AUTHOR: Finkellp M.Ya. TITLE: On the'Paper by I'.G.Antypko and G,P'.Zhbannikoval "On the Temperature *of Gas After Primary Coolers" (K statlye Antypko i G.P~.Zbbannikovoy 110 temperature gaza posle pervichnykh kholodilinikov") PERIODICAL: Koks i-Khimiya, 1957, Nr 10, Pp.63-64 (USSR) ABSTRACT: In the original paper, published in Koks i Xhimiya, 1957, Nr 21 an increase of the temperature of gas leaving primary coolers was proposed. The author points out that such a measure, which gives only insignificant advantagesp is detrimental to the operating condition of the whole by-product plant and therefore cannot be recommended. zt~(". n ' ASSOCIATION: UKhIN.

As a rule, two metals have similar values of atomic radii in a three-component system (Cu and Au or Fe and Ni, etc.). For interstitial phases this need not be so and a third metal can be interstitial in an alloy of two others. Aumerous regularities (standard types of structures) are observed but there are some alloys which cannot be fitted in. These are characterised by a high Al content and extremely various structure. They are, for example, Mg 3Cr2A1181 Cr4Si4All3l O-Cu2lbAl?, 11i4MnllAl6O The main regular classes are: uard 1/2 SOV/70-3-4-10/26 On Certain Regularities in the Structures of Triple Metallic Compounds 1) Triple electron compounds with electron concentrations of 3/2. 1 2~ Triple interstitial phases.

There were no TiC lines in X-ray diffraction patterns from aged specimens, probably because of excess of other secondary phases in the residue. The temperature threshold for the sigma-phase is below 9500C and the concentration "Threshold" is about 0.035%. If alloying elements enter appreciably Into the Intermetallic compounds, they leave the solid solution and the solubility of carbon rises. The mechanism of sigma-phase formation during ageing at 8000C is more likely to be directly from austenite and not in association with chromium- carbide formation.

TITLE: Plastic deformation of textured beryllium PERIODICAL: Fizika tverdogo tela, v- 3, no. 3, 19611 796-802 TEXT: Single crystals of beryllium show highly anisotropic mechanical properties on account of their hexagonal crystal structure. A study has now been made of the mechanical properties of high-purity beryllium foils. For this purpose, thin textured Be foils of high purity (99.987% without taking hydrogen into account) were prepared_by condensaticn of beryllium vapor on molybdenum sheet in a vacuum of 1.10 6 mm Hg. The rate of evaporation was 0.2 g/cm2-hr, the condensation temperature was 300-3200C, and the tempera- ture of heat treatment was 7000C for one hr. These conditions were the same for all specimens. The purity was checked by a determination of the resist- ivity ratio: R 4.20K/R2930K - 9-10-3 _ 1.5.10-2. The grain size varied from 8 to 15 p, the foils had a thickness of 170-300 p, and the density was Card 1/5 Plastic deformation ... 20791 S/181/61/003/003/017/030 B102/B205 1.831 91CM3. The texture was studied by X-ray analysis using a tube de- signed by B. Ya. Pines and V. S. Xogan. Two different textures (I and II) were studied. Texture I of the Be foil showed no relationship with that of the molybdenum backing which had been oarbidized. The X-ray diagrams showed no (002) linep i.e., an axi symmetric texture with the axis rootl (perpendicular to the surface of the foil) could be assumed. Texture II showed "interaction" of the condensate of hexagonal beryllium with the backing(body-centered cubic Mo) with the texture (100) [0111 . on account of this "interaction", the basalplane (002) was orientated at an angle of 450 toward the surface of the foill, which resulted in a shift of the inter- ference points. The plastic defo!rmation (rate: 1% per min) was studied at 20-80000. The temperature'waiis measured by means of a Pt-PtRh thermo- couple (accuracy: +20). The specimens had a size of 50 x4 x(0-17-0.3) mm. Three kinds of specimens with different directions of the texture relative to the direction of expansion were studied. Type T: The basal plane coincided with the plane of the specimen. The temperature dependence of the breaking point a b of the longitudinal expansion 6 and of the lateral contraction T was measured (Fig- 4). The maximum value of a b at room tem- Card 2/5 20791 S/18 61/003/003/017/030 Plastic deformation ... B102YB205 perature was 43 kg/mm2. 6 increased monotonically from 14% at room temper- ature to 77% at 6000C. These specimens showed a three-dimensional plastici- ty. X-ray analysis disclosed effects of prismatic sliding in the entire range of temperatures (20-8000C). Type II: The basal plane formed an angle of 450 with the plane of the specimen. It showed practically the same temperature dependence of ab; at room temperature ab - 44 kglmm2 and 6 - 18.% (somewhat higher than in the case of I). These specimens exhibited a two- dimensional plasticity. The temperature-dependent variations in width and thickness are illustrated in Fig- 5. The two types show different ru ture. Type III: The same texture as II but expansion in the direction E610T. These specimens showed a particularly low strength; at room temperature, there is practically no longitudinal expansion. X-ray diagrams showed no variations. Only at 2000C they showed an insignificant shift of the intensi- ty maxima. Maximum 6 appeared at 5500C (26.5~). The behavior of these specimens on expansion in one direction perpendicular to the plane of a prism of type II is similar to Be single crystals. I. A. Gindin and V. S. Kogan are thanked for a discussion. There are 6 figures and 16 references: 11 Soviet-bloc and 5 non-Soviet-bloc. Card 3/5 8/18 06719~03/003/017/030 J Plastic deformation ...

Orientated'growth of beryllium precipitates on oriented TITLEt and on isotropic bases PERIODICAL; Fizika metallov i metallovedeniye, 1961, Vol.129 No.1, PP-73-77 TEXT: The Plasticity of beryllium can be increased by preparing it with a preferred orientation. A preferred orientation can sometimes be obtained by condensing the metal onto a base with a preferred orientation or by changing the angle between the direction of the molecular stream and the normal to the base. In the present work, the structure of beryllium precipitates prepared by the condensation of vapour in vacuo on a textured base of various metals, and also the variation of structure with the angle of inclination of the molecular stream to the bass, were investigated, The-method of precipitation used was described earlier (Ref.10t Fmm, ig6o, lo, 4, 581). Beryllium of 99-987% purityAdiscounting oxygen) was vaporized in a resistance furnace with a BeO crucible.

The precipitate was annealed for 1 hour at 700 to 7 00C, Precipitation was carried out in a vacuum of (1- 5) x 10-2 mm HS. Rolled sheets of Mo, Ta, Ni, Cu, Ti and armco Fe were used an a base. The texture of the bbndensed beryllium was investigated by X-ray methods. Some of the photographs obtained are shown in the paper (of a layer condensed on a molybdenum base, on nickel. and on an amorphous bass). Fig.2 shows the orientation of the crystals on the same bases. The results are given in the table. Epitaxial growth was observed in several cases with precipitates up to 500 -o thick. The best plastic properties of beryllium were obtained by condensation in the (2111 direction on a molybdenum base, and on a neutral baBe. The orientation of beryllium condensed on a nickel base is unfavourable for plastic deformation. There are 2 figures, 1 table and 16 references: 9 Soviet and 7 non-Soviet.

Previous investigations of the crystalline structure of Ni-,Cr alloys in the temperature range of 1840 to 19300C indicated the presence of a cubic, face-centred P-phase of chromium and the possibility was suggested that chromium exists in five allotropic modifications. To verify these assumptions, a study was made of the crystalline structure of 80 x 10 x-.2 mm chromium specimens with a purity of 99,94%. The examination was made i~ a high-temperature X-ray camera, which was first evacuated to 10- mm HS and then filled in with argon to the pressure of 300 mm Hg. The specimen was heated by passing through �t electrip, current (up to 600 A).

TITLE: The high temperature polymorphism of beryllium PERIODICAL: Fizika metallov i metallovedeniye, v.12, no.6, 1961, 865-872 TEXT: Measurements of the electrical conductivity of beryllium were carried out on specimens in the form of plates about 0.3 mm thick, prepared by condens ng beryllium vapour on molybdenum sheet at 3000C and 2 x 10-~ mm Hg pressure. The beryllium was of purity 99.96 to 99.97% (total metallic impurities 0.01%, oxygen content 0.01% and carbon content less than 0.02%). The density of the beryllium was 1833 g/cm3. The plates had axial symmetry with the '[0011 axis perpendicular to the surface. Electric resistance measurements were carried out in the range VIK 18 to 128oOc, in an atmosphere of purified helium above 900*C. Fig.1 shows the relation between temperature and relative electrical resistance of beryllium. Curve 1 is for 99.97% beryllium and shows a continuous smooth increase with increase in Card 1/3 33453 - S/126/61/012/oo6/010/023 The high temperature ... E021/E435 temperature. Curve 2 is for 98% beryllium. This shows the effect of impurities in the region 2oo to 8oo0c. Curve 3 is for 99.97% beryllium after 10% deformation and annealing at 9000C for l..5 11, and shows the effect of residual stresses which are difficult to eliminate. At 1254 + 5*C the electrical resistance increases rapidly, due to a polymorphic transformation. Samples similar to those used for electrical resistance measurements but no less than 0.5 mm thick were investigated by X-ray analysis. The results showed that there was a transformation at 1254 + 50C from the hexagonal a-Be lattice to the body-centred cubic P-Be lattice with the parameter a = 2.5464 kX. The transformation was accompanied by a decrease in specific volume.

PERIODICA.L:Fizika Metallov i Metallo-~mdeni-ye, 1958. Vol 6., Nr 4. pp ?5?-?60 (USSR) ABSTRACT: It was reported by Finkell that in a wide range (80%) of plastic deformation the intensity of the (310) lines (Co-radiation) of coarsely grained steel remained practically constant. bnde~r the same conditions, the intensity of the (211) lines (Cr-radiation) was 1.4 times higher, but also did not depend on the degree of the n1astic deformation. While grairting that this.fact is ;f great practical interest, O.N.Shivrin disagrees with Finkel's interpreetation of his experimental results and Card 1/12 points out that: (i) It has been shovm (Ref.l.~ 2) the SOV/126-6-4--)8/34 Discussion on V.M.Finkells Paper m "Ox~ystal Lattice Distortions in Coarsely and Finely Grained Steel During Cold, Plastic Deformation" process of blar,,k..fi-agma:.a-at:Lon. which causes weakening .of the extinction effect practically ceases at 8-10% deformation; with inoreasing deformation one should expect a decrease of the line intensity as a result of the foribation of distortions of the 111-rd type. Such an effect was in fao+~ vbze.T-.,ed by Shivrin in the case of steel 2 deformed by turning at high rates of feed and small depth of the out-, and iu -the case of brass and copper under hydrostatic pxessure: In every case the intensity of lines inereasqd up to a certain degree of deformation only, (ii) Since the intensity of the diffraction bactkgroizid is associated with the magnitude of the distortions of the 111-rd type, but not with the extinc~tion effect, the fact of its remaining coastant during deformation of coarsely grained metal is quite ircomprehensible. No matter how strong is the masking.effect of extinction on the Card 2/12 weakening of the inter-aity of the lines due to SOV/126-6-4-28/34 Discussion on V.M.Finkelvs Paper on "Crystal Lattice Distortions in Coarsely and Finely Grained Steel During Cold, Plastic Deformation" distortions of the 111-1d type, the magnitude of which should be considerable at 80% deformation, their effect should be reflected in the variation of the background intensity. This, for some -reason or other, was not observed by Finkel). (iii) Block fragmentation results in (a) weakening of the pAmary extinction effect which is directly associated with the size of the blocks, and indirectly in (b) weakening of the secondary extinction affect due to the increase of the degree of disorientation of the blocks within the orystallites. This means t]3a-.t a metal can be characterised by coarsely grained structure and still not show any .secondary extinction effect if only the structure of the crystallites is sufficiently close to the ideal, and that tho secondary ex'u-inetion effect can be considerable even in finely grained metals if only the degree of disorientation of the blocks within each crystallite is sufficiently small. The character of the variation of the line intensity will depend on Card 3/12 whether the primary or secondary extinction only, or SOV/126-6.-4,28/34 '. Discussion on V.M.Finkeihs Paper on "Crystal Lattice Distortions in Coarsely and Finely Grained Steel During Cold, Mastic, Deformtion" both these.effects take place in a polycrystalline metal specimen. It is easy to show that, as was postulated by Avarbach (Ref-3, 4) in the presence of primary extinction only,, the variation of the intensity of the lines of high orders is negligible. (This fact, for some reason or other, is overlooked by Finke!Q On the otber hand,, the presence of secondary extinction (Ref-5, ~), particularly when the conditions are favourable for the formation of texture (Ref.?)-, the variation of the lines intensity can be quite different. For this reason Finkel's contention that the observed effect was caused exclusively by the secondary extinction is not quite justified., since in the case under consideration the effect of texture might have been the predominant factor. (iv) The difference (not much larger than the limit of the experimental error) of the values of 4iT`2 in the (310) and (211) dire6tions can be attributed not only to the anisotropy of the Card 4/1p distortions of the 111--rd type; but also to the , M1 SOV/126-45j6.28/-34. , " Discussion on V.M.Finkell's Paper Coarsely and Finely Grained Steel on "Crystal Lattice Distortions in During Cold, Plastic Deformation" difference between the depth'of penetration of the Co- and Cr-ratliation. Some authors favour the hypothesis of the weakened surface layer in which small distortions are neutralised. In the final analysis the correctness of this or other theory can be proved only by further experimental work. There are 9 Soiiet references.

In the case7of the heat-treated rail steel, the size of the mosaic blocks was smaller by OnO Card 5/12 order of maguitude (e.g. 2 x 10--6cia at 10016 deformation). SOV/126-6-4-r28/34 Reply by V.M.Finkd Consequently, the observed phenomena cannot be attributed to the effect of primary extinction in either case since primary extinction is practically non-existent at the size of the regions of coherent dispersion quoted above. (Ref.3, 4). To account for the stability of the intensity of the (310) lines, one has to assume that its decrease due to the effect of micro-distortions of the 111-rd type is counter-balanced by an opposite affect of some other physi.cal factors, such as secondary extinction and texture. The secondary extinction can, in all probability, display itself throughout the whole deformation range: In its initial stages it is associated with the process of block fragmentation and the resulting disorientation of the mosaic blocks9 in the later stages it is caused by the process of disorientation not directly connected with the block fragmentation (Ref.5). Unlike secondary extinctiong the effect of primary extinction (in a coarsely grained aggregate), being associated with the process of Card 6/12 fragmentation only2 probably disappears in the initial Reply by V-M.Finkell Card ?/'12 S'OV/126- 6-4-28/34 stages of the deformation (having increased the intensity of the lines), after which the intensity of the lines decreases due to the effect of the distortions of the 111-rd type. Shivrin carried out his experiments on brass and copper in which the size of the mosaic blocks is one or two orders of magnitude larger.than that in steel, so that..the maximum on his curves is obviously associated with the effect of the primary extinction. When a high carbon content steel is quenched, a structure is obtained which is submicroscopically nonhomogeneous, and which is characterised by small size of the blocks and high degree of their dimorientation. This minimises or possibly even elimi tes secondary extinction, which would explain the differemt character of,the variation of the lines intensity with defoTwation in annealed and quenched specimens of steel 3. He (Finkel) did not take into account the effect of texture, since this effect in the case of plane (310) is negligible (Ref.?). In addition, hacL the observed phenomena been attributed to the effect of taxture only, it would imply that the character of the texture in SOOV/126 6-4-,e~,8/34 Reply by V.M.Finkell steel 3 and rail steel is basically diffe3:ent (since in the former case 1(3~0) is constant and 1 increases With increasing degree of deforma~121651), while in the latter case both 1(310kand 1 211) decrease) Which, of cours6, cannot M e. I~ is difficult to understand vChy Shivrin should be surprised by the fact that the background intensity in deformed steel 3 did not change: The variation of the background iutenBity in the high carbon content, rail steel did not exceed 7-8%. It is.only to be expected that it should amount to less in the case of steel 3 in which, owing to its low carbon content, the lattice distortions caused by deformation are much snaller ~bau. those in steel'3. Since the variation of the backgroand intensity is generally small it cannot be used as a practical criterion of the degree of lattice dist ortion. As regarding Shivrin's comments on the problep of anisotropy, the hypothesis of the weakened surface layer does not Card 8/12 seem to have any bearing on this problem: Unstable, Reply by V.M.Finkelf 6 0 V/1 2- - /3 4 elastic distortions may be present in the surface layer, while distortions of the 111-rd type are of non-elastic nature,, There are 9 Soviet references.

The quoted figures do, in fact, exclude the 'b lity of the intensity ,rssi i of the (211) and (31 lines being affected by pri-Imary e2rtJnction, but then he (Shivrin) did not assert that such ~n effect was possible. On the contrary, he emphasized that secondary extinction is not directly Card 9/12 associated with the size of the blo(*s and that such a SOV/126, 6--4-28/34 Comments of O.N.Shivrin on the Reply of VJA-Finkell direct connection exists in the case of the primary extinction only. (ii) The data on the size of the blocks given by Finke~ are not reliable.. If the quoted size of the blocks in quenfahed and tea ered rail ste~el deformed 10% is in far:,t, D = 3.8 x 10-Fem then the width of the lines (310) calculated from the Selyakov formula is B = 0.285 radion or 160. This broadening is supposed to be due to the small size of the blocks only, without taking into account the effect of the distortions of the 11--nd type. Under these conditions the (310) lines would disappear completely arid one could not discuss the variation of their intensity, This proves that the quoted data on the size of the blocks are incorrect. (iii) The assumption that, secondary extinction diminishes throughout. the whole deformation range cannot be regarded as well substantiated. since increasing disorientation of the blocks leads to its rapid disappearance. (iv) The increase of the lines intensity observed in brass and copper cannot be attributed to the effect of Card 10/12 primary extinction since this effect is negligible SOV/126-6 -.4 -28/34 Comments of O.N.Shivrin on the Reply of V'M.Finkell 0 already at the size of the blocks equal to 1 x 10-4 emo In the case under consideration the size of the blocks was 4 x 10-5, o.9 x lo-5 and 4 x 10-6em. at 2. 5 and. 20% deformation, respectively. (v) Finkel's statement that the character of texture in the rail steel and in steel cannot but be the same, has not been questioned. However, it should be borne in mind that even small additions of alloying elements can af4ect the character of texture formation (Refol2).

Seriya fizicheakdya, 1959, Vol 23, Nr 5, pp 611-614 (USSR) ABSTRACT: In the introduction the influence exerted by texture on the intensity of X-ray interference is stated as being explained by the orientation of the structural grain surfaces. To eliminate this influence it is necessary to introduce a method making it possible to record all or at least most of the reflecting surfaces of the structural grains and to measure the reflec- tion intensity. As this would require the rotation around any axiel the authors applied the method tested in the determina- tion of deformations of the 3rd kind, permitting the measure- ment of the intensities of the various interference lines, A principle scheme of such a system is shown (Fig 1). The ground section is inclined by a certain angle and the inter- Card 1/2 ference is observed. Next, a graph is given depicting the SOV/46-23-5-15/31 On the Possibilities of Eliminating the Influence Exerted by Texture on the Intensity of X-Ray Interference mechanical arrangement for the rotation of the crystal (Pie 2), and mathematical considerations are made concerning the in- tervals of intorferenoe lines in dependence of the angle of rotation. The results obtained with this method are compared with other methods in a diagram, and it becomes evident that it is actually possible to eliminate the influence of the texture. Two X-ray pictures are given in the appendix for an exemplification. There are 4 figures and 11 references, 7 of which are Soviet.

The present paper reports two methods for studying the small angle scattering in elastically and plastically strained copper. In the first method the primary X-ray beam is very narrow and this is achieved by careful collimation. This method requires long exposures (of the order of 100 hours). If a counter is employed as the detector, considerable errors are introduced owing to an appreciable X-ray background due to the scattering by slit edges and to cosmic radiation. From the-experimental point of view, the method is very difficult and requires high-output tubes. The second method is based on the apparatus described by Zhurkov and Slutsker (Ref. 6). Here, a divergent beam is limited on one Card 1/4 S-/1-39/60/000/005/001/031 Eb32/Ell)+ A Study of Small Angle Scattering in Elastically and Plastically Strained Copper side by a screen and a baffle placed at a distance frcm each other. The baffle serves to absorb the radiation scattered by the edge of the screen. In this method angles of the order of 11 from the primary beam can be investigated. The present authors have modified the Zhutkov-Slutsker method as follows. A wide mono- chromatized beam is passed through a collimator consisting of three slits. The width of the first and second slits can be adjusted within the range 0.3-0.5 mm and the actual width is chosen so as to obtain the maximum possible intensity as well as a geometrically sharp beam on one side. The optimum slit widths 'are chosen empirically. The third slit is in the form of a lead baffle having a sharp edge and absorbs radiation scattered by the e7dge of the second slit. In practice this baffle is brought right up to the beam without actually entering it. The total length of the collimating system is 160 mm. The specimen is placed immediately behind the baffle and coincides with the centre of rotation of the counter. A 0.1 mm wide slit is placed in front of the counter.

The region where the intensity increases very rapidly (1000-4000 pufies/sec in the first mimte) was taken as.the atarting point for the measurements. The total width of the primary beam was about 201. The device has been used to measure X-ray scattering in the region up to 2-31. Since the experiments were only preliminary, all the measurements were carried out in air.
