ABSTRACT: X-ray diffraczion studies have been made of the resions
of the crystal lat'Gice adjacent to the slip hand in a
deformed crystal of rock salt, The Debye temperature of
this region has been measured and appears to be only half
that of -the undeformed crystal, The static displacements
of atoms in the slip band and far from it have been
measured. Rods of NaCl 0.8 x 0.8 mm in cross-section,
were examined at room temperature and at liquid-oxygen
temperature by rotation photograph. The films were photo-
metered to give the 200 9400 and 600 integrated intensities.

TITLE- -Tri-e-Influence of Annealing on the Stvueture of the
Crystal Lattice in a Slipband of Rock Salt
PERIODICAL: Kristallograftya, 1959, Vol 4, Nr 3, pp 438-440 (USSR)
ABSTRACT: Measurement of Laue photographs showed that in the.slip-
bands of deforiued crystal of NaCl the crystal latticeis
in an unotable state. Annealing at. a temperature near
to the rielting. point fully re-establishes the lattice and
the interatomic bondinG- This is shoi-m by the observation
that after annealing the characteristic Debye temperature
returns to its proper value. At 600 OC the re-establish-
ment of0the lattuice be.-ins to proceed intensively and
at 400 C there is practically no change. This is
surprising as sti-ldies of the phenomenon in specimens of
pure t-,ietals sho-ured no changes In Debye temperatu-re. A
graph is given of the neasured Debye temperature and the
mean static displace.-.,.ent of the atoms against annealing
temperaturo. The normal undeformed Debye temperature is
280 OK and -w-hen the crystal is deformed by a load of

displ.acement is about 0.18 k. Iuvestigations were also
made of the scattering background between spots in the

state. Full return to the normal state of the crystal
required about 10 hours at 760 OC.

TITLE: Determination of the Static Displacements of Atoms in the
Slipping Band of Rock Salt (Opredeleniye staticheskikh

PERIODICAL: Izvestiya kkademii nauk SSSR. Seriya fizicheskaya, 1959,
Vol 23, Nr 5, pp 606-6io (USSn)
ABSTRACT: Pirst, reference is made to the method developed by
G. V. Kurdyumov and his collaborators for the determination of
the static displacement of the atoms in the deformation of
metals. It was found that when subjecting metals to cold-treat-
ment their Debye temperature does'not change. As ras shown by
N. A. Brilliantov and N. A. Obreimov, a large number of slip
planes is generated on the deformation of parallelepiped rock
salt crystals; these planes are visible in the polarization
microscope. The determination of the Debye temperature of non-
deformed crystals is then dealt with, and the values obtained
are tabulated. Sample measurements are given in connection with
the Debye temperature in the slipping bands. A micropicture of
Card 1/2 such a slipping band uith a pola-rization microscope is then
-Detex~mination of the Static Displacements of Atoms SOV/48-23-5-14/31

shown, and the values measured on some samples are also
specified. Next, mention is made of the relationship between
the mean displacement square and the Debye function, and the
computed values of the root mean displacement squares of the
atoms are specified. The static deformation is dealt with next.
Measuring values of atom displacement in the slipping band and
pertinent values of Debye temperature are tabulated. Results
show that plastic deformations are not restricted only to the
slipping bands, but that also atoms lying at a considerable
distance are affected by them. This unstable atomic state may
undergo recrystallization with an appropriate thermal treatment.
This is likewise investigated and results are sumnarized in a
table. There are 3 figures, I table, and 6 Soviet references.

T EXT The authors investigated the resistance to wear of 18KhNVA grade
steel utilized for heavily loaded gears after bending subjected to heat treatment
used at the plant (cementation, double tempering at 6500C with 6 hours 30 min,
holding, oil-hardening from 8500C, tempering at 140-1600C for 2 hours)- high-
temperature hardening (heating after cementation in a salt bath at 985 6C, 10 min
holding, tempering at 140-160 C), and step-by-step hardening (after cementation
and high tempering the parts were heated to 810 + 10 0C, 25 minutes holding, trans-
ferred to an oil bath with a temperature of 160j7O OC, 5 min holding and cooling
in air; tempering at 1500C). For the manufacture of gears the authors recommend

TITLE: Thermal Etching and Annealing of Twinned Layers in
Crystals of Antimony V~l
PERIODICAL: Kristallografiya, 1960, Vol. 5, No. 3, pp.472-475
TEXT: The study of twinned layers with dimensions 5 to 20 ji in
single crystals of antimony has shown that annealing at 600 C
(for less than 5 hours) leads to the establishment of mono-
crystallinity in the specimen. The twin boundaries and the glide
steps are the place -s-ihere the most intense thermal etching occurs.
Edge dislocations have been discovered both in the parent crystal
and in the twinned part. The dislocation lines lie in the 111
plane. The 111 planes in antimony are the directions of the
principal cleavage. The crystals of antimony were obtained, after
preliminary zone refining, by the Shubnlkov-Obreimov method.
Specimens utere in the form of plates 2-3 mm thick and 10-12 mm
in diameter. They were prepared by cleaving the crystal which had
been grown. The defdrmation produced in this process gave rise
to the tivinned layers mentioned, The examination was carried out

TITLE: The Formation of Dislocations in the TwiLi~ng~o'f Calcite
PERI6DICAL: Kristallografiya, 1960, Vol.5, No.59 PP.737-71+3
TEXT: It is found that in calcite a twin boundary not
containing dislocations is made visible by selective etching
although the intensity of etching is significantly less than the
intensity of etching at dislocations. The existence of incoherent
twin boundaries containing dislocations has been experimentally
shown. In the crystal In the twinning process complete
dislocations are formed. The twins were produced by Garber's
method (Ref.5). Twin layers were studied on the face of the
crystal not forming steps on twinning, i.e. 100 or 010. The twin
plane could be indexed as 110 with the boundaries of the twinned
layers parallel to rpofl.

ABSTRACT- Knoopfel, Loopfo, Stoll at al.,(Refs 1-3) reported that Gsl crystals
grown from superheated (to 800-9000G),melts exhibit luminescence and
have an d.-yield of 9.3%. The present authors repeated Knoopfal, V/Z
Loopfe, Stoll at al's work using analytically pure (Series 1).
zone-refinod (Series 2) and very pure (Series 3) GsI crystals.
Crystals of Series 1 and 2 were found to contain 2.3 x 10-4-2.7 x 10-5;r.
Tl; their absorption spectra (Fig 1) had a Tl band at 299 mp.
Seriso 3 crystals were subjected to chromatographic purification
and quadruple re-crys tall I zation; this treatment reduced the amount
of Tl in Chem to below 10-7% (Fig 2) and no scintillations were
observed on "citation 'with K-ray*. Samples of each series were placed
in carefully cleaned quartz ampules , which were evacuated, sealed and
heated for up to 5 hours at 9OOkG. After such heating temperature

Luminescent Properties of Caasium Iodide Crystals Grown from Superheated Melt
of 3-5 um/hour. The relative y-aciatillation yields of crystals ol' each
series are sham in Fig 3. Series 1 yields rose with the dumtion of
superheating to about 60% (after 5 hours heating). while those of
Series 2 and 3 rose to over 10/. after 1-2 hours and an further super-
heating fell to below 10/QL The results obtained show clearly that
luminescence produced by superheating cannot be due to thallium
impurities, but it is probably caused by dissolution of quartz
itkpuritioa and consequent activation of CsI with silicon; the
hypothesis of Knoopfel, Loopfe, Stoll at al. that this luminagconce
is due to iodine vacancies was rejected by the authors - Acknowl ed Vn ants
are made to R.S. Budnik and L.G. Maystrenko for help in growing of
crystals and measurements on them,and to A.N~ Fanova for obtaining the
absorption spectra. There are 4 figures and 9 references, 4 of whidh

TITLI: The Temperature Dependence of Luminescence of N&I(Tl) Crystals at
Temperatures of 0-27000. -, 1 11
MIODIGAL: Optika I spektroskoplya, 1960. Vol 8, Nr 4, pp 541-544 (USSR)
ABSTRACT; The reported (Refa 1-4) tomperaturo d6pandances of the intansity of
luminescence of Nal(TI) are contradictory. The aim of tho present
work was to study the temperature dependence of the intensity of
luminescence of NaI(Tl) with 0.05-0 .1% Tl excited with Ii-rays. The
temperature dependence was obtained between 0 and 270'OG at the rates
of heating varying frcm 15 to 90 do&/hour. An N&I(Tl) crystal of
13 mm diameter and height (4 in Fig 1) was placed in an aluminium
container 6 inside a copper block 3 which was joined by means of a
copper rcid with a heater. Tonperatures were measured with a copper-
constantan thermocouple and the temperature difference between the

TEXT: The authors investigated the twinning process of antimony mono-
crystals caused by mechanical deformations by studying selective
corrosion which allows dislocations to be determined. The samples (thin
disks, 2 - 3 mm thick, diameter; 10 - 15 mm) were cut out from the mono
crystal in the direction of the (111) cleavage traces, the caustic
solution was composed of 9 unit volumes of concentrated nitric acid and
4 unit volumes of distilled water. As appears from Figs. 1 and 2 a
d-is-twinning leads to an incomplete regeneration of the crystal lattice
and causes lattice defects. These defects in turn cause a hardening of
the crystal, The experiments also showed that the dislocations may form
at any point of the twinning layers. As is shown by theoretical

considerations and by experiments (Refs. 3, 4) elastic twinning does not
lead to disorientation of these two blocks if the angle between the two
blocks is not more than 2 - 31. During the study of selective corrosion
it was observed that this angle is smaller than 1/2'. Finally, it is
demonstrated that dislocations occur in high-purity antimony monocrystals
on bending the crystals also by a gliding of the crystallographic planest

mutual discrientation of two blocks. When such a crystal is annealed,
the boundaries.of the blocks are sh4fted and, consequently,-the disloca-

TITLE: Motion of twinning dislocations in calcite
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 141, no. 3, 1961, 607-610
TEXT: The mechanical stress which starts the motion of twinning disloca.
tions, is an important factor in the description of twinning processes. The
present paper reports on tests which have been performed to determine these
stresses. The motion of twinning dislocations was observed by the method
of repeated etching suggested by J. Gilman et al. (Dislocations and Nechan-
ical Properties of Crystals, N. Y., 1957, P. 116). The mechanical stress
which caused the motion of twinning dislocation, was induced by pressing
the diamond pyramid of a nMT-APMT-3) microhardness device into the specimen.
BY varying the load of the diamond pyramid that load was determined, at which
twinning dislocations started moving. For the calculation of the forces
acting on each dislocation, strain-field formed by neighboring dislocations
had to be allowed for. The stress required for starting a motion ranged
between 60 and 15 9/mm2, and was dependent on the amount and character of
the neighboring dislocations. The authors voice the opinion that these

values might permit the determination of interaction forces between dis-
locations. The establishment of equilibrium distribution for dislocations
in accumulations was analyzed. Results point to the fact that the resist-
ance of dislocations to a motion is equal for all dislocations and -is equal
to the starting stress. If there is no external stress, then the following
relation will be valid for the starting stressI5~ - 6' n Gb when
0 o - L (I-V)
denotes the number of dislocations in ail accumulation G the shear modulus
b the Burgers vector, L the length of the accumulation, and V Poisson's
ratio. This expression was derived on the assumption that the barrier be
sufficiently long, that the dislocations be arranged in straight lines, and
that the f0rce acting on a dislocation be evenly distributed. Test results
are compiled in Table 1. The large spread of 6~ is caused by the curvature
of dislocations and similar properties of the crystal. The authors thank

TITLE; On the structure of the accommodation region in

PERIODICAL: Fizika metallov i meta-Ilovedeniye, V.13, no.3,
1962, 441-450
TEXT. Bismuth and zinc were purified by zone refining, and
monocrystals of these metals of high purity were obtained.
Specimens were cut from the monocrystals along the cleavage plane
at liquid nitrogen temperature (in order-to reduce deformation
by slip). on splitting a crystal, stresses are set up under the
action of which twinning bands form. Therefore, application of
additional stress for the production of twins and accommodation
regions is unnecessary. The specimens were studied with a
.'metallurgical microscope, using oblique illumination, and with
a microinterferometer. In order to expose dislocations in
bismuth, monocrystals of this metal were etched in a solution
consisting of 10 parts H2SO4, 10 parts H20 and 1 part HN03 (67%).

The zinc crystals were irradiated with a converging beam and then
annealed. A special attachment to the metallurgical microscope
was constructed by means of which changes in the accommodation
region during annealing could be kept under constant observation.
After annealing, the zinc crystals were again irradiated and
studied metallographically, Polygonisation of accommodation
regions was observed to occur when the dimensions of the latter
exceeded 100 Ii. on annealing, fusion of blocks of polygonised
accommodation regions occurs. The algebraic sum of the angles
,between the blocks agrees well with the resultant angles between
blocks produced after fusion, which confirms the dislocation
struzture of the accommodation re-gion. Selective etching of
monocrystals of bismuth showed that dislocations concentrate at
the boundary between the accommodation region and the parent
crystal. In zinc crystals no polygonisation of accommodation
regions of less. than 100 ~A dimensions takes place during
only a decrease of the width of this region occurs.

ABSTRACT: The setup fvr inducing elastic twinning is illustrated in Fig. 1 on the
Enclosure. Tho load was measured by a slotted spring dynamometer with an indicator
(with a precision of 25 g). The sample was immersed in liquid nitrogen for the
experiment. Twinning developed in Bi at this teuqierature by the appearance of
elastic twins, much like the growth of twins in calcite and antimony at room
teuperature. At some value of internal atresas thin wedge-like twin layers formed
under the knife edge or near it,, growing with increase in load. In their experi-
ments, the authors were unable to determine any definite relationship between
thickness and length of the elastic twins. It was necessary always to apply some
finite load to the crystal to induce the elastic twinning. This value varied from
experiment to experiment,, but was alwayL; smalls near 0-3-0.5 kg, This suggests
some incipient mechanism for the formation of such twins. The actual causes may
Card 1/3

be many. It is concludod that each act of acquirine and of losing twinning leaves
its trace in the crystal. Defects are apparently formed in the crystal lattice
where twinning develops, and these defects accumulate with increase in number of
loading cycles, facilitating the wedge-like growth of the elastic twins. Gliding
may be an important factor in this twin growth. Orig. art. bast 4 figures.

scope (polarized light) under magnification much larger than 200.

fact structure of the crystals. The process of expansion of the

ABSTRACT: The authors study the effect of temperature on hardness and creepin
polycrystalline methane at nitrogen and hydrogen temperatures. Since methane is
tively dissolved by nitrogen and hydrogen, the specimens were prepared and their
a
c
hardness was determined in the same hermetically sealed cryostat. The specimens
were transparent without visible flaws and had a smooth horizontal surface. The
hardness of the methane was determined by.sinking a conical indenter into the speci.-
men. The loading unit of the instrument consists of a metal cylinder with a weight,
of P = 600 g. On the lower section of the cylinder are three conical indenters 1- --
with vertex angles of 900 located equidistantly around the cylinder. Penetration
of the indenter was monitored on a cathetrometer with an accuracy of 0.01 mm. In
determining the hardness, penetration of the indenter is given as h = h1+ h2 where
hl is penetration under a load P1 10 g, which is read on a spring indicator; h2

of the Enclosure. Curves for argon and krypton are given for comparison (C. Treppg,,..-
Schweizer arahiv., Bd. 24, 191, 230, 1959). A reduction in temperature was found
to reduce the creep effect in solid methane. A physical explanation is giveA for

ABSTRACT: The strength and ductility of polycrystalline ammonia are studied as func-
tions of temperature under unilateral pressure. Cylindrical specimens 10 mm in dia-
meter and 40-mm long with uniform microstructure and polished ends were studied at
temperatures from 77 to 160OK4 Curves are given for the breaking point, limit of
proportionality and relative com resolon as functiona of tompanturo. Thena data
show that crystalline ammonia ~4 extremely low strength properties and ductility.
Solid ammonia is quite brittleiat the temperature of liquid nitrogen and shows elas-
tic deformation right up to the breaking point. At stresses of 0.5-0.6 kg/mm2,cracks
are formed parallel to the axis of the specimen with an accompanying characteristic

sound and a slight reduction in loading (up to 100 g). The final breaking stress of
IvO.8 kg/mm2 remains constant throughout the experimental temperature range. At this
point there is an instantaneous reduction in loading to zero and the specimen is
shattered. The shape of the fragments and the slight degree of deformation before
the breaking point show that cleavage is the mechanism responsible for fracture of
ammonia crystals between 77 and 1300K. Above 1300K (0.6 T ), the ductility of the
M
specimens increases and creep is observed under a constant load. Shearing is respon-
sible for fracture above this point since cleavage strength remains nearly constant
wiib temperature, while an increase in temperature causes a considerable reduction
in shearing strength. The relationship between rate of uniform creep V and stress a
is V= AGn, where A and n are constants equal to 500 and 5 respectively at 1600K and
stresses greater than the limit of proportionality. The energy of creep activation
is found to be 5.6 Kcal/mol. This is approximately 10% lower than the,heat of sub-
limation for solid ammonia. Orig. art. has: 3 figures.

ABSTRACT: In view of the fact that the experimentally observed connection between
the speed of dislocations and the applied voltage In these crystals have not yet
been fully explained theoretically, the authors have attempted to obtain different
information on the character of dislocation motion In single-crystal KBr, in vhich
the motion of dislocations has not been heretofore investigated. The tests were

above approximately 80 dmm2 the dislocation velocity increases rapidly and then
increases' at a slower rate. There was little difference betweed edge and screw

ABSTRACT: The authors have measured the elastic scattering cross sections of C12 and.
Be9 for 70 MeV electrons at different scattering angles between 30 and Mo in order
to evaluate the root-mean square radii of the nuclei. The 70 MeV electron energy was-
chosen for the measurements because at that energy the momentum transfers are high
enough to permit determining the momentum transfer dependence of the form factor, an
yet low enough to allow of neglecting higher powers than the second (of the momentum
transfer) in the expression for the form factor. The electron beam was produced by
a pulsed accelerator. The primary beam intensity was measured with a secondary
emission monitor which was calibrated with a Faraday cup. The electrons that were

ABSTRACT: An attempt is made to determine the stress relationship of the

ties. On the basis of experimental data, it is concluded that the broadening of
twin layers occurs by a heterogeneous mechanism. The activation energy is
determined for the processes of twin layer broadening and twin growth in the
direction-of shear. It is established that 'the process of-twin layer broadening in
bismuth involves the simultaneous reorientation of about 104 atomic planes and

ABSTRACT: A description is given of a simple oscillator of short (10'-8 see) triple
electrical and light pulses, suitable for adUstlng of high speed scaling circuits,
coincidence circuits, and for investigation of photomultiplier parameters. The
advantage of such an oscillator is that it overcomes the shortcomings bf its prede-
cessors which are capable only of single pulse outputs, either electrical or light
signals. The input oscillator of the system develops pulses of 50 V with A
duration front of 10 to 15 nsec and sequence freqaency from 1000 cps. Hydrogen dis-
chargers are employed in the generator,. The pulse shift is achieved by an allternatins
lag pattern having a magnitude of 0 to 0.5;,gsec. The width of the produced electrical
pulses is 10 nsec, and that of light pulses, 50 nsec. Orig. art. has: 2 figures.

dence of resistivity, the rare earths divide themselves into two groups. rn La,Ce,
Pr,Nd and Yb thoro Is no region in which the resistivity is a linear function of
:temperature. The curve for Nd is given; it is smooth and concave to the temperature'
axis. In Sm,Gd,Tb,Dy,Ho,Er and Tu the resistivity depends linearly on temperature
throughout the paramagnetic region, and the curve has a sharp bend at the paramam-
netic-antiferromagnatic transition point. The behavior of Eu (curve given) is very
peculiar: there is no linear region (up to 3000K), and the peculiarity at the tran-
sition point is very marked, there being even a small region in which the resistivi~
ty decreases with increasing temperature. This behavior is tentatively ascribed to
ichanges in the conditions of scattering and in the energy spectrum of the current i
.carriers. The Hall emf in all the rare earths is proportional to the Induction
throughout the paramagnetic and antiferronagnetic regions. In some of the metals
the current carriers are holes, and in others they are electrons* The number of carw
riers per atom varies widely, from 0.17 (holes) In Eu to 3.5 (electrons) in Lu. The
behavior of the Hall emf in the ferromagnetic region is very complex. Orig.art.has:

temperature ranges (i.b--4.2 and 12--20.3K). The terms proportional
to the different powers of the "Lemperature correspond to conduction-
electron scattering by electrons, phonons, and spin waves. It is
concluded t1hat at helium temperatures the conduction electrons. are,
scattered in ferromagnetic gadolinium by spin waves, this type of
scatteringibeing absent in nonferromagnetic ytterbium at the same
temperature. "The authors are grateful to S. V. Vonsovskiy for his

ABSTRACT- The electrical resistance and Hall effect are excellent indicators of the
characterishes of the electronic structure of solid bodies. The present paper describes
simultaneous measurements of the electrical resistance and the Ha-U effect for alarge
group of hj&y purified/rare earth metals. The electrical resistance of neadymium,
europium, gadolinium,fterbium, dysprosium, holmium, erbium and ytterbium was
measured by a common potentiometer in -a metal cryostat at temperatures beturaen room
and4.2K. The electrical resistance differed significantly from that of ULO usual metals
with low -resistance, The temperature relationships could be used to divide the rare

earth metals into four grcoups. The first group contains neodymium and ytterbium, which,
do not show a.Unear relationship in the above-mentioned temperature intervale Ile
second group includes dysprosium, holmium and erbium, which show breaks in the curves,
and low resistance maxima when passing from the paramagnetic into the anti-ferromagnet-
ic condition. The third group contains gadoliniu and terbium, which show a sharp break
when passing from the paramagnetic to the anti-ferromagnetic condition, with a linear
relationship in the paramagnetic field. Europium has a special place aroong the rare
earth metals. It shows a sharp drop in electrical resistance below the point of passage
from the paramagnetic into the anti-ferromagnetic condition. The detailed behavior of
europium requires further investigation. Analysis of the curves for all the rare metals
shows that the specific electrical resistance at equivalent temperatures is higher than
for metals in the first group of the periodic table. The Hall effect, was measured with
a DC potentiometer in a cryostat for europium, holmium,, arbium and dysprosium,- the
authors being the first to measure the Hall effect of europlum and holmitum. Tezrperature
variations did not change the Hall effect. On the basis of these tests and publications by
C. J. Kavan, S. Legvold and G. S. Anderson, k can be seen that all the rare earth
metals may be divided into a "light"group (up to gadolinium) and a "heavy" group, in both
of which the waductivity depends on the electronic bonding. The paper further describes
