Spectrograms of the gegenschein,~ere obtained with a fast nebularspectrograph having a focal rati 1:0.7 and a dispersion of 2000 A/mm at 5500 A. The observations were carried out in 1956 at the Alma-Ata Observatory and in October, 1957 at -he High Altitude Station of GAISh near Alma-Ata (H = 3060 m). The spectra were obtained on DH and P~-3 (RF-3) plates using an exposure of one hour and a slit width of 3 mm (1956), and OAF plates using an exposure of 30 min and a slit width of 4 mm (1957) The calibration was carried out using 0-particle excited phosphors of the type described by Kharitonov on p.164 of the present issue, The relative intensity of the above lines in the region of the gegenschein and in the night sky were measured at the same zenith distance. Detailed numerical results aremIxoduced in a table. Card 1/2 69326 S/033/6L/038/001/009/019 E032/E514 On the Intensity of the Principal Emission Lines of the Night Sky in the Region of the Gegenschein The mean relative intensities of the three lines were found to be 0.99 + 0*01 51 1.02 + 0.036 and 1.08 + 0.04., respectively. The observations give no indication of line intensification. Strictlv speaking, this result has no connection with the concePt of the gegenschein as the gaseous tail of the earth. It merely shows that these lines are not excited in the tail even if a tail does exist. A study of the principal emission lines in the region of the gegenschein does not provide information about the nature of the latter. A detailed study of the spectrum of the gegenschein in a wide spectral interval is necessary. There are I figure, I table and 17 references: 8 Soviet, 9 non-Soviet.

A description is given of two very-high-speed low-dispersion nebular spectrographs: HCC (NSS) which is a glass prism,instrunLent for the visible region and HKC (NKS),'which is a quartz prism instrumeat for the violet and ultra- violet regions. These spectrograTphs were designed by V.I. Bedel and N.V. Lobachev and constructed under the direction of P.V. Doby-1 chin in 1954. The spectrographs each had a tube which widened in ..front where there was a large precision-made nebular slit of 300 MMI length, a prism and a camera with a.sinqple collimator lens focused on the sliti They were: used, along with a C5 63 (SP63) spectrograph Pard -1 .. .. . .....

TITLE: The counterglow as the effect of scattering of solar light by interplanetary dust particles PERIODICAL: Astronomicheskiy zhurnal, v-39, no.4, 1962,.689-701 TEXT: This paper is concerned with the optical theor-y of counterglow in which the latter is interpreted as being due to the scattering of solar light by interplanetary dust particles. The analysis is mainly concerned with the photometric profile of counterglow and the energy distribution in its spectrum. In order to account for the known properties of counterglow, the following assumptions must be made. It is necessary thata certain fractioii of dielectric particles must be present in order to account for the enhanced brightness at the antisolar point. The spatial distribution of the dust may_be either constant-or decreasing in accordance with the r 1 law, or finally, there may be a tendency for the dust to concentrate in the asteroid region. The lat;ter gives the best agreement with the observed photometric profile at angular distances of 180 to 1600 from the sun.. The Card 1/2 The counterglow as the ... S/033/62/039/004/oo6/oo8 F,032/E514 size distribution of the particles Ca-p da is such that 1) = 4 or 5. When p = 4.9u to 95%.of absorbing particles with an albedo of A,-- 0.1 are required in addition to the dielectric particles. When p = 5 the counterglow may be explained by scatter- in& off dielectric particles only. This value of p gives better agreement with the observed energy distribution in the counterglow spectrum. A higher value of p would not yield the observed photometric profile. In the case of a constant or r - particle density, the number of particles with radii greater than 0.6 ji is found to be approximatelY 5-10 3 CM-3. If the dust is preferentially accumulated in the asteroid region, then the avejage concentration in that region should be of the order of 10- 2 and their conjentration at the earth's orbit then turns out' to be less than 10- 3 cm-~` (a> 0.6 10. The general conclusion is that with suitable adjustment of the particle parameters the optical theory is capable of explaining the main feature of counter- glow. There are 4 tables ane. l.figure.

Together with the conclusion regarding the absence of any intensifica- tion of primary emission lines of the night sky in the region of the counter- glow, the presence of a continuous counterglow spectrum has been established. Energy distribution in the counterglow spectrum in the region -?%-4600-6500.x was found to be very close to the energy distribution in the zodiacal light spec- trum; however, in the 4300-4500 X region a clearly expressed excess was detected. in comparison with the spectrum of zodiacal light. -It was also determined that Ca~d- -1/4 ACCESSION NR: AP4017623 the energy distribution in the counterglow spectrum in the XX4250-6500 region corresponds to scattered solar light with an intensity proportionil'to~ 'K7" , where X lies within the range 1-2, with the most probable value x 1. 74. Observations of the energy distribution in the counterglow spectrum in the -A;L3900-6500 ~ region were made by N. N. Pariyskiy with a nebular spectograph (glass and quartz cameras) during 1957-1959. The energy distribution curve is given in Figure Lof the Enclosure. It can be represented by I(k) - cK"Eo(;k),: where E0 (,A) is the non-atmospheric spectral illumination from the Sun at the mean distance from the Earth to the Sun. In the computations, the value of E0 (X) as given by Johnson (F. S.'Johnson, Jour. of Neteor., 11, 431, 1954) is adopted. The parameter x is computed by the method of least squares: x .1.28- =0.16. The continuous spectrum of the counterglow is the solar spectrum scattered by solid particles of interplanetary dust. Orig. art. has: 2 fig- ures and 1 formula. ASSOCIATION: Astronomicheskiy in-t im.

Modern instruments can penetrate to a dis- 010 tance of 10 million light years. Within this radius exist 1 galaxies or ,1021 stars. Life need not necessarily be similar to the terrestrial. The number of civilizations in our galaxy can be represented by Nkjk2pjp21(Qy! 1 where N is the number of stars in the galaxy and N is the number of civilizations, i 0 Caid L 3670-66 ACCESSION NRt AP5024060 D k is the factor accounting for the presence of a planetary systom, k 2 's the factor accounting for the lifo-supporting possibilities, P'l iG the probability 01' life existing under favorable conditions (probability = 1), P2 the probability i, that life has evolved to an intelligent form, and f(tc) the factor accounting for the durability of a civilization. The last factor has supporters for both the short range and long range theory. The value for our civilization may be 0,25- 0.5. The most precisely determinable factor is k1, and many feel that k, is e-1.. The factor k2 is difficult to evaluate, but probably lies in the limit 10-6 05 - 1010 0.06. This would give 1 planets in our galaxy capable of supporting life. It is likely that p2 also equals 1. The possibilities of civilization 5 existence extends from one in every five neighboring galaxies to 10 per galaxy. The communications could be of three typest a) direct contact or exchange of information; b) contacts along a communications channel; c) contactsof a com- binod type (sending out a space probe and receiving information). The possibil- itiea of those three types are explored for different distances. It Is concluded that for distances of loss than 100 light years all three types are possible and that for longer distances one-way communication is favored. Relativity Card 2/3 L 367o-66 ACGESSION NR: AM14060 considerations are used in computing the times involved. Radio waves present the most favorable form of communication. The strength of the radio signal depends both on distance and on the transmitter energy output, so the civilizations are in three types, depending on the energy requirements: type K I (approxi- mazely the same technical level of development as our civilization) has an energy roquirement of 1019 - 1024 erg/see; K II with 1033 erg/Bee, which means that this civilization has completely mastered the energy of its star; and K III with an' ener,Tf requIxoment of 1044 - 1045 erg/soc, which moans that it has mastered the ener;-,.- of the entire galaxy. For conummications with earth-like (K I) civiliza- tions, radiations near the wavelength of hydrogen (21 cm) seem to be a natural . choice, and it is used in experiments with passive listening (such as Green Banks in the USA). Although results have not been favorable to date, equipment is being Liproved and the program continued. Probability calculations for two type K I civilizations contacting each other with this random scanning of apace were made. If type K II or K III civilizations exist, the possibility of coramunica- tiona -..if-h them is greatly enhanced. Orig. art. hasi 5 figures, 2 tables, and 2 formulas.

B. Sholomitskiy, M. G. Darionov, and N. F. Sleptsova of the State Astronomical Institute im. P. K. Shternberg have been carrying out systematic measurements of radio emissions coming I from stellar radiation source CTA-102. In order to avoid errors inherent in absolute measurements, -radiation from this source was compared with the radiation of radio source 33-48, observed simultaneously. The measurements showed that the ratio between the emissions from CTA-102 and 3C-48 varied within a range of 30X. Since the radia- tion intensity of 3C-48 was shown to be uniform, the variability of the CTA-102- radio source appears to be an undisputed fact. Orig. art. han: 1 f igure.

Abstract : Authors studied reaction to tularin (allergen used in diagnosing tula- remia) using skin biopsies from 21 immune and 3 non-immune guinea pigs. Non-sensitizeci (non-immune) animals showed only a slight skin reaction; in immune anim.1s, the reaction was prolonged and more severe. Histo- morphological and histo-pathological findings, effects on the organs and other tissues are described. Authors conclude that reaction fol- lowin.a administration of the vaccine strain or of tularin was less malignant than the reaction from the virulent strain. 7 references, 7 USSR, 3 since 1940.

The formation of granulomas in the ~experlmental animals was characterized mainly by productive inflammation and, un- i !like the control, the granulomas did not become necrotic. The infectious proccss in ~guinea pigs inoculated with low doses (10 microbial cells) was generally restricted ito the inoculation site and regional lymph nodes, but in animals inoculated with massive doses (10 million microbial cells), the process spread beyond them to the ,viscera.

The now method proved more advantageous than the conventional onei it required less time and no pickling. The pulverizing apparatus In simple, inexpensive and easily adjustable to automation. After coating the bimetal ohoet3 were welded air-tight on the perimeter and the and surfaces. The rolling tests were made on a 2,300-mm stand at Chelyabinsk by the standard method. The welding seams prevented warping and lamination of the bimetal sheets. The tight- i neas and the strength of the seams depended on the surface quality of the stain- lose and carbon steels composing the sheet and on the assembly and welding of the sheet layers. The deformation of the various layers in rolling was not uniform.

(Moscow) TITLE; On the control of chemical reactions SOURCE: Problemy kibernetiki, no. 5, Moscow, 19061, 97-103 TEXT: This paper is a general discussion of some ideas that may be relevant to the automation of processes in the chemical in- dustry. The basic ideas of this paper were reported and discussed at a seminar at the Vsesoyuznyy institut aviatsionnykh materialov (All-Union Institute of Aviation Materials) in 1946, under the lea- dership of Ya. I. Frenkell, now corresponding member of the Aca- demy of Sciences USSR. The author argues that there is a need to establish a branch within cyberneltics to deal with the specific problems arising in chemistry. The main purpose of "chemical cy- bernetics" would be to construct devices for the automat-L,-. contiol of chemical processes, using sensing elements and information pro- cessing units. At present, however, the most important problem i5 the algorithmization of chemical processeeg I.e. the construction Card 1/3 S/582/61/000/005/005/012 On the control of chemical ... D222/D306 of logical schemes for the kinetic, technological and other pro- perties, and the construction of "chemical" algorithms. Two' kinds of factors are distinguished that can influence the course of the processes: Internal (those which originate in the phyaico-chamical properties of the reacting substances), and external (those or-&-- ginating in the environment of the reaction; i.e. temperature, eto.). The author concentrates on the internal factors. It ie sug-, ,gested that the dispersion of results, observed even with eeeming- ly rigorously controlled uniform conditions, is due to the fact t6t -the experimental specimens have a kind o-rL individual nature due to the complexity of their physico-chemical structure. Small fluctuations in these properties can give rise to either a conveT- gent or divergent tendency in the results. Examples of processes where such an individual nature of specimens is found are the co1r... rosion of metals, electrochemistry, chemical kinetics, semiconduc- tore, strength of materials, and so on.

Institutioni Nona Title: Investigation of Plastic Properties of Beryllium Monocryst~Lla 'Zriginal Periodical: Fiz. metallov i metallovedeniye,, 1955, 1, No 3., 529-537 Abstract: transition of the Be monocrystal into a fully-twinned state is related to the process of mechanical twinning in the (102) plane) and is particularly easy to ef- fect at 4000 and ab-:,ve. In addition to the principal system of twins along (102), one observes also tudins in the (101) and (103) planes. The mechanism of slipping of Be depends substantially on the temperature and orientation of the specimen. In ame specimens, base slipping is observed even at -1960. The plasticity of Be, which in- creases monotonically with temperature, reaches a maximum at 4000 (B z 26%) and di- minishes somewhat at 6000, and increases again at 8000. The mechanical character- istics of the plasticity of monocrystals of beryllium are determined, and their de- pe-'adence on temperature. The yield point when slipping along the (100) and (101) planes diminishes by approximately 4 times when heated from 200 to 8000. _Q_VV~2 - 2 - Crtr;gory : USSR/Solid State Fhysics - ','iechr-nical Fropertics of % Orystp.1s rmd Crystrllino Co-pounds Abs Jour : Rof Zhur - Fizika, No ~', 1957, i~io 6787 ;-.uthor : Grrbor, R.I Gindir I.A,j Kogan, V.S., Lezarev, B.G.

A similar structural change is 41 bound in iron samples after rolling in liquid nitrogon, but in this cane the deGree of refinement is higher than on the occasion of pres-ging the ball through the tube. The degree of refinement in iron and nickel after treatment at low temperatures followed by heating to 20' depend3 on the size of grain of the initial structure as well as on the degree of deformation. For the pro- duction of microdistortions the initial stages of deformation are of import- ance at low temperatures, on which occasion the work performed by exterior forces goes over nearly entirely into the latent deformation energy. On the occasion of deformation (beginning with an 8,'/a deformation) as a result of pressing a ball through a tube micropores are produced, a process which may be connected with mechanical twin formation. In all the cases of recrystallization at low temperatures investigated on this occasion, deformation was broucht about by the formation of creeping stripes either in a pure form (nickel) or in connection with twin formation (iron).

PERIODICAL: Fizika Metallov i lAetallovedeniye, 1957, Vol.5, No.2, pp. 326-330 (USSR) ABSTRACT: In earlier worh of the authors (Ref.3), it was found that work hardenin(S caused by grinding activates diffusion processes which then may become very intensive even at room temperature. It was, therefore, considered of intuerest to machine such specimens end make X-ray exposures of these under conditions such that these processes axe either completely eliminated or at least appreciably reduced. For that purpose zinc monocrystals were ground along their cleavage planes at the temperature of liquid nitrogen (-1960C) and X-ray patterns taken directly after grinding, prior to heating them to room temperature and aftsr "ann aling" at room temperature and at 100, 150 and 200 0.

As a result of annealinr,-,, of the specimens, certain details viere detected in the state of the lattice of the surface layer of the specimens after grinding,which were not detected in previous experiments, during which the specimens were work hardened and subsequently investigated at room temperature without any heat treatment.

Under the recrystallized zone there is a layer in which the monocrystal consists of blocks with orientations approaching the initial orientation and the depth of these layers increases with the annealing temperature.

TITLE: Investigation of the Plastic Properties of Aluminium at Low Temperatures (Issledovaniye plasticheskikh svoystv alyuminiya pri nizkikh temperaturakh) PERIODICAL: Fizika metallov i metallovedeniye, Vol 7,,Nr 5, pp 794-800 (USSR) wp ABSTRACT: Pure aluminium (99.994A Al) and technical aluminium con- taining up to 1% impurities (Si,, Mn, Fe) were used for the investigation. The specimens were in the shape of plates of 2.5 x 2.5 mm cross-section and 17 mm working length, widening at the ends for ease of~gr4ping in the testing machine. After grinding and polishing, all specimens were annealed in vacuum for one hour at 3000C. The average linear grain size in pure aluminium was 1.0 to 1.5 mm, and in technical aluminium 0.3 to 0.5 mm. Deformation was carried out In a vertical-tX* teasile testb* machine using mechanical loading, being specially adapted for low temperature work. Card Tensile tests were carried out at 293, 77, 20, 4.2, 2.06 and 1.40K. In this apparatus it was possible to carry out 1/4 tensile and compression tests in liquid hydrogen as well as SOV/126---7-5-25/25 Investigation of the Plastic Properties of Aluminium at Low Temperatures. In liquid helium at 4,20K and below. A temperature of less than 4,20K was obtained by evacuating helium. The layout of the apparatus is shown in Fig.l. A study of the macro- and microstructure of fractured specimens has shown that the nature of plastic deformation of aluminium changes fundamentally with change in temperature from 20 - 4.20K and below. Fig.2 shows the microstruGture of an aluminium specimen (99.994%), fractured at 200K. Fig.3 shows the microstructure of a similar specimen fractured at 4.20K. In Fig.4 the macrostructure of aluminium specimens (99.994% Al) fractured at 200K (a) and 4.20K (b) is shown. In Fig.5 load-extension curves for cylindrical specimens of technically pure aluminium of 3 mm diameter (annealed at 30000 for one hour, grain size 0.3 mm) are shown for various temperatures. In Fig.6 load-extension curves for flat pure aluminium specimens of 2.6 x 2.5 mm section (annealed at 30000 for one hour, grain size 1-1.5 mm) are shown for various temperatures.

The defleotlon of a scratch at the boundary of large blocks is visible Fig.10 shows the deflection of interference lines at the ;oundary of large blocks of a pure aluminium specimen deformed at 1.40y'. In Fig.11 the dependence of the mechanical properties of aluminium on temperature In the range 1.4 to 29511 is shown. The authors arrive at the following conclusions: 1. It has been foiaid that a sharp difference exists in the macro- and microscopic nature of plastic deformations of specimens of pure aluminium if the temperature at which they are strained is changed from 20 to 4.20K and below. A lowering in the temperature of testing leads to an intensifi- cation of the inhomogeneity of plastic deformation; i.9. to the formation of large blocks the sizes of which exceed those of the average metal grain. 2. The plastic deformation of aluminium at 4.20K and below is characterized by an unstable flow which is expressed the Card 3/4 more clearly, the lower the testing temperature. Preliminary cold working of the specimens intensified the interrupted SOV126- --7-5-25/25 Investigation of the Plastic Properties of Aluminium at Low Temperatures nature of flow. 3. At 4.26K and below the formation of mechanical twins is observed in aluminium. It is possible that the instability of plastic flow is associated with the formation of mechanical twins. 4. The mechanical properties of aluminium in the temperature range 77-1.40K have been determined. It has been found chat the true strength of specimens of pure and technical aluminium tested to fracture at 4.20K are close to one another. The ultimate tensile stress os is practically independent of temperature, The residual elongation has a maximum in the range 20 to 4.20)1.

TITLEz The Low-Temperature Polymorphism of Metals (NizkotemperAturnyy polimorfizm metallov) PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1958, Vol 35, Hr 3, pp 802 - 804 (USSR) ABSTRACTs In the present paper (unlike the practice adopted by several earlier papers dealing with the same subject) the method of mechanical tests is used, in which the compression diagr--m of lithium, sodium, cesium, bismuth, and beryllium samples with subsequent heating are investigated. Also the varia- tions of volume in inverse transformation are recorded. These tests were carried out on a one-ton machine with a rigid dynamometer, which is suited for carrying out measure- ments at helium temperatures. The velocity of deformation was constant and amounted to 0,03 mm/sec, A graph gives a typical diagram of the deformation in the coordinates "stress absolute compression" for lithium. At 770K this is the melting curve with consolidation of the shape at high degrees Card 1/3 of deformation. There are no singular points indicating a The Low-Temperature Polymorphism of Metals sov/56-35-3-46/61 transformation. If the deformation temperature drops to 200K and less (down to 1A OK), a characteristic discontinuity is observed on the curve with a sharp decrease of resistivity against deformation. The Most direct proof of the polymor- phous transformation in the tests discussed are the variations of volume in inverse transition while the deformed sample is being heated. Similar curves were obtained also for sodium. In the case of cesium no polymorphous transformation is observed on the deformation diagram even at i,4 OK. Ne-erthe- less, the shape of the curve of heating allows UB to conclude that, to a small extent, such a transformation actually exists. This behavior of the three alkali metals is apparently ocn- nected with the reduction of characteristic temperatu--.9 and leads to the conclusion that polymorphism exists in tae entire group of alkali metals. The discontinuity of stress in the compression diagram is observed also in the case of beryllium at temperatures of 4,20K and less. All this seems to indicate an extensive occurrence of low-temperature poly- morphism, which is observed in the case of tin, sodium, lithium, cesium, bismuth, and beryllium.

TITLE: Study of the Plastic Properties of Monocrystals of P Berylliu PERIODICAL: Fizika metallov i metallovedeniye, 1959, Vol 8, Nr 1, pp 130-139 (USSR) ABSTRACT: In the present paper slip processes in monocrystals of beryllium which have not been submitted to preliminary twinning have been studied and the relationship between slip and fracture of beryllium in the white temperature range has been established. Specimens were made from monocrystals of a beryllium block grown by slow cooling of the melt in vacuum. The purity of the original material was 99.7%. Cutting of the block was carried out by an electro-corundum disk on a grinding machine. The worked layer was removed by etching the beryllium with an aqueous solution of hydrofluoric acid. The specimens had the shape of a rectangular prism, 3.5 x 4.0 x 7.0 mm. All prism facets were ground. Two side faces (3.5 x 7.0 min - type-a face and 4.0 x 7.0 min type-b face) were polished. From the Lauegrams it was Card 1/5 evident that the crystals were undistorted. The experi- 66900 SOV/126-8-1-18/25 Study of the Plastic Properties of Monocrystals of Beryllium. II. ments were carried out under conditions of compressive deformation on a special press (Ref 6) at a constant deformation rate (0.03 mm/sec) at temperatures of -253, -196, 20, 4oo, 600 and 8000C. The specimens were orientated in such a way that the basal plane (0001) made an angle of 45 + 1,50 with the axi.s of the compressive forces (Fig 1). The side face of the specimen was parallel with the crystallographic plane of the primary prism (110 and subsequently also parallel to the primary diagonal Y120D . The metallographic and X-ray methods used for the studies have been described earlier by Garber et al, (Refs 1,7). Indexing of the exposed elements of plasticity and fracture was carried out according to the traces of deformed bands and cracks on previously polished specimen faces. The results vrere plotted on a standard stereographic projection of the basis plane of the crystal. An X-ray analysis method was used for the orientation of specimens and for the supplementary control of elements of slip and fracture. The structure of the bands of basal Card 2/5 slip was studied also electronmicroscopically, In Fig 2 traces of slip occurring in monocrystals of beryllium at f6901 SOV/126-8-1-18/25 Study of the Plastic Properties of Monocrystals of Beryllium.

Photo- micrographs of the surface of specimen faces after compression at 200C are shown in Fig 3a and b and the micro-interference picture of the relief of these surfaces in Fig 3b and 2,.. The slip bands have been resolved electronmicroscopically as slip packets. At -196 and +200C the thickness of the packet is the same, namely 0.1-0.3 IL (Fig 4). The magnitude of slip can be estimated from the displacement of a scratch intersecting the trace of the slip band in a type-b face (Fig 5). In Fig 6 compression curves for monocrystals of beryllium (curves for various slip temperatures along the abscissae axis) are shown. 1 mm along the abscissae axis corresponds to 60 IL deformation; 1 mm along the ordinate axis corresponds to a load of 18 kg. Fig 7 shows the temperature dependence of the mechanical characteristics of monocrystals of beryllium: a s - yield stress in compression, ab - UTS in compression; 6 - total residual compression; b - residual compression prior to the appearance of tRe first slip bands.

Fig 11 is a standard stereagrapb-ic projection of the basal plane (0001) of a monocrystal of beryllium. The orientation of monocrystals of beryllium is shown in Fig 12. The authors arrived at the following conclusions: 1. The essential aspect of plastic deformation of beryllium in a wide temperature range (-1-960 to +8oo0c) is slip along the base (0001) in the direction (112q . t~~ Card 4/5 The slip in beryllium differs fundamentally from that in 6f 9r"/ SOV/126-8-i-18/25 Study of the Plastic Properties of Monocrystals of Beryllium. II. other hexagonal crystals, Beryllium has a large number of different crystallographic twinning systems. Mechanical twinning is not responsible for the great brittleness of beryllium. Re-forming of twins within an entire crystal leads to an increased plasticity and strength of the crystal in subsequent slip. An unevenness in movement along basal slip planes has been observed. This causes the formation of microcracks along prism and secondary pyramidal planes. Thus the brittleness of beryllium is associated with a large number of cleavage planes which are exposed particularly strongly because of the non-uniformity of slip at low temperatures.

The investigations described here were carried out with purer Be single crystals (9q.98;,,) at 77 and 200K. Further, slipping on (0001) under the influence of a deforming force forming an angle of 450 with the plane (0001) was investigated. The direction of displacement in the case of basic slipping was parallel to the lateral face of the investigated crystal - the diagonal of first order [1120] . Deformation was brought about by means of a machine which was especially constructed for operation at low temperatures (Refs 3, 4); the rate of deformation was 0.03 mm/sec. Card 1/3 The character of slipping was found to be highly dependent on ~4 The Slipping of sov/56-36-2-5/63 Beryllium Single Crystals at Low Temperatures III the stage of deformation. In the case of weak deformations, there is no immediate slipping along the 3trips, and displacement occurs in a thin layer resting against the strips. Thus, the part of the crystal between two strips is displaced as a whole. Residual stroas causes elastic displacomont of the opposite sign in the crystal layers resting against the strips. In the case of strong pressure slipping takes place along the strip, and strong relative displacement occurs. The formation of a saw-shaped profile of the crystal face is characteristic of this stage; this may, according to reference 8, be looked upon as a result of twinning on planes with large indices in the case of basic slipping. The discontinuity of displacement is explained as being due to the existence of impurities. Purification of the beryllium contributed towards rendering the course of displacement along each strip more continuous, which leads to a higher degree of plasticity. At 770K the formation of whole packets of strips can be observed, which is very clearly shown by figuxe 7. The method of building up the face profile of deformed crystals makes it possible to determine the basic dimensions of the fine structure of the elementary slipping Card 2/3 strips and of the packets. The twist noticeable between the The,Slipping of SOV/56-36-2-5/63 Beryllium Single Crystals at Low Temperatures III strips can, in the first stage, be considered to be due to residual stress; this twist, which increases with deformation, must necessarily be explained in tho advanced stage, when it attains 30, as a resuit of twinning. In conclusion, the authors thank 1. M. Fishman for constructing and producing the replicae and for making electron-microscopical recordings.

It was the aim of the authors to find the cause of the different be- havior of the interfaces under static load. Preceding papers (Refs. 1 and 2) -have shown that the t*in layer became thicker, and that one interface of the twin layer remained immobile, while the other was shifted. For their study , the authors used iron (degree of purity: 99.99%, grain diameter: 2 - 2.5 mm) which was annealed for five hours at 8000 after polishing the boundary faces. A multistage deformation at the temperatures of liquid nitro- gen was carried out on the samples with room-temperature heating in between. It was thus possilbe to observe the appearance and disappearance of the twin Card 1/3 81618 Slippage Along the Boundaries of Twins During 5/161/60/002/06/06/050 Direct and Reciprocal Twinning of Iron B122/B063 double layer, as well as its boundary shift with increasing load. The deforma- tion to be reached per deformation step was chosen from 0.1-0.5%. Changes were observed by the microinterferometric method with a microscope of the type NOW-4 (MII-4) and by variations arising in the etched lines. Experi- ments established that the lines suffer a break on compression and are displaced on a boundary plane. This displacement was likewise observed on the break of the interference stripes on one baumdary. The displacement, however, did not increase with further increasing load. If the displacement was missing in the initial deformation stage (it could not be observed on all identical boundary layers of a twin system), it did no more arise on any further intensification of the deformation. It is conoluded therefore that the slippage along the plane (112) must take place before the twin formation, i. e. while the lattice changes over to the twin formation. An "accomodation region" often forms besides the displacement on the slip plane. Still, one phenomenon does not necessarily entail the other.

TITLE: Dispersion and Re-establishment of Contacts Between Micro- blocks During Plastic Deformation2p PERIODICAL Fizika tverdogo tela, 1960, Vol. 2, No. 6, pp. 1089 - 1095 TEXT: The low strength of solid bodies after deformation is ascribed to dislocations, fractures, and microcracks and the resulting concentratioll of strains which attain the value:of theoretical strength in microregion8. Furthermore, the formatioY4 splitting, and disorientation of microblocks are observable. The concentration of strains may be regarded as an increase in latent energy which is due to the extension of the inner surface brought about by disorientation. The surface energy of the liberated parts of the block surfaces would pass over into latent energy. The block dimensions themselves have a specific value for every material. According to B. M. Ro- vinskiy and L. M. Rybakova (Ref. 7), this value constitutes a mean value of split and restored blocks. In this connection, the saturation of the latent deformaiion energy corresponds to the stabilization of the mean block Card 1/3 X 81620 Dispersion and Re-establishment of Contacts S/181/60/002/06/08/050 Between Microblocks During Plastic Deformation B122)Bo63 dimensions. The surface energy is determined by formula;y - 01 where a = v/l~ le 7th S/12, , v denotes the volume of the block, 1 its ng S is the surface, ~is the material density, q is the latent energy of plastic deformation on saturp-tion referred to the sample mass, and a is the mean surface tension. As an exan~ple, I has the value 0-5 for copper, i.e., on plastic deformation of copper a considerable part of the block surfaces is without contact with the neighboring block6. It is then oonsi- dered that a part of the latent deformation energies must be also ascribed to other causes, such as lattice defects, dislocations, and residual stres- ses. The latter a3~e determined in metals roentgenographically, and do not amount to more than 2 ~ of Q. Atomic dispersion and imperfections, de- termined from the change of resistivity as a result of plastic deformation., correspond to only 5 %*of the latent energy Q. 1%us,alziost---the entire latent energy of the plastic deformation was found to be present as the energy of the free block surfaces. The process of contact re-establishment was studied on pressed and high-vaouum heated copper disks, on the change of the ::'low vel,sity of hydrogen through iron tubes, which were deformed at the tfamper.- atures of liquid nitrogen, and finally, on the change, caused by annealing 7 Card, 2/3 81620 Dispersion and Re-establishment of Contacts S/1,91/60/002/06/08/050 Between Mioroblocks During Plastic Deformation B122/BO63 in light dispersion intensity of deformed rock salt samples. The setups used for the investigation are shown in Figs. 1 - 5, and respective re- 8UltS in Figs. 6 - 9. The studies revealed that the activation energy of contact formation in copper decreases with rising pressure, i.e. the said formation proceeds very quickly at a certain pressure and also at low temperatures. In the case of iron, a recrystallization occurs under the given conditions, which, however, does not necessarily give rise to con- tacts. It is concluded therefrom that at a certain deformation stage there is a firm inte'rlinkage between the various contact faces of the blocks besides dispersion and disorientation.

Tubular copper samples (diameter: 1.5 mm; wall thicknesss 0.45 mm) were used. The samples were first annealed at 800 0C for 8 hours (at 107 6 torr). Special care was devoted to the perfect cleanliness of the inner wall of the tube. The sample was deformed in vacuo at.20 and 4.20K perpendicular 16--o the tube axis until the inner walls touched, and further., until the plastic. deformation ~ - 23 %. The sample was then heated at low.'pressure, and kept at room temperature for 10 - 15 hours. Recrystallization was observed on a cut -:!f the cross section of the tubes after deep etching, by using a metal- lographical microscope of the type M~M-6 (MIM-6)(Figs. 1 and 2). Small Card 1/2 Y 81621 Low-temperature Recrystallization of Copper S/181/60/002/06/09/050 B122/BO63 bridges of reorystallization grains were observed along the contact planes.

The experiments showed that copper deformed at low temperatures is well recrystallizable already at room temperature, and that the idea of temperature threshold of recrystallization is a preliminary one, i.e., when constructing the recrystallization diagram it is necessary to consider the temperature at which the plastic deformation is activated.

TITLEi On the Effect of Preliminary Straining at 300*K on the Mechanical Properties of Technical Iron at 77*K PERIODICAL: Fizika metallov i metallovedeniye, 1960, Vol 9, Nr 3, PP 447-455 (USSR) ABSTRACTi According to the theory of dislocations, brittleness of the body-centred cubic metals is due to blocking of dislocations on dissolved impurities (Cottrellt atmosphere) or other obstructions. If this is true, it should be possil-le to lower the critical temperature of low- temperature brittleness by preliminary deformation in the temperature range in which the metal is ductile, followed by cooling through the temperature range within which blocking of dislocations takes place. The object of the investigation described in the present paper was to check this hypothesis by studying the low-temperature mechanical properties of technical iron, containing 0.03% C, pre-strained at room temperature. The experimental tensile test pieces (1-5 x 3.0 mm cross-sectiong Card 1/8 10 mm gauge) were prep4red from a central portion of a 69698 S/126/60/009/03/021/033 E193/E483 On the Effect of Preliminary Straining at 3000K on the Mechanical Properties of Technical Iron at 770K forging. In order to completely remove the cold-worked surface layer, the test pieces were etched and electrolytically polished, after which they were vacuum annealed at 300 C for 4 h. In the course of the investigation the microstructure, grain size, character of deformation and distribution of the slip bands near the fracture of the test piece were studied. The treatment, illustrated in Fig 1, to which the test pieces were subjected comprised three stages: (a) preliminary straining within the elastic range (up to a stress ao) or preliminary plastic deformation (up to elongation 60) at room temperature (3000K), at a low (vl = 0.4 micron/see) strain rate; (b) slow cooling (approximately 50/min) of the test pieces under the load applied originally (ie with ao or 60 maintained constant) to the liquid nitrogen temperature (770K)l straining the test piece to fracture at 770K, at the normal strain rate Of V2 = 30 micron/see.
