The presence of high stresses of the first order in the surface layer can be explained by the con- siderable strengthening of tle latter and the particular nature of the strained state in the layer determined by the penetration of roentgen rays into the metal. This state possesses the nature of oriented stresses of the second order. There are 21 references. I.K. Translator's note: This is the full translation of the original Russian abstract.

Nr 4. . PP ?57-?60 (USSR.) ABSTRACT: It was reported -',1y Firike-11 %haV. in a wide ranse (80%) of plastic deforma-,ion the intensity of the (310) lines (Co-radiata.on) of c09-rSely grained steel remained practically oonst-ant . 1,1ndeT 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 T)lastic def ormation'. aiile granting that this . fact is of great practical interest. O.N.Shivxin disagrees with Finkel's interpretation of Lis experimental results and Card 1/3.2 points out that: (i) It has been shown (Ref.1, -2) the SOV11 26- 6-4-28/3 4 Discussion on V~b!.FiLlml's Pap,:~- cra, "".rfstal lattice Distortions in Coarsely and Finely Grained Steell Du_-ing Cold, Plastic Deformation" p:vocess of _Lnagn_~~iLtation vihLzh causes weakening of the extinction effect prar~-tical.11.y ceases at 8-1070 deformat-Lon; wItla :in~-,.reasing deformation one should expect a decrease off the 1-ine intensity as a result of the formation of distortions of the 111-rd type. Such an effect was in _Pac.47 vbse-inred by Shir-rin in the case of steel .2 d'-formed by turning at high rates of feed and small de-oth cf the and iu -ULe case of brass and t 4 .% copper u-nder hvd-rosta ~ pxesssure: In every case the in-censitty of lines iin,3i-easi,~o. up to a certain degree of deformation only, (ii) Since the intensity of the diffraction ba:,~.kground is ass-z;_ziated with the magnitude of t.r-e distortions of the 111-rd. type, but. not with the extinction effect, the fact of its remaining constant d:L;ring deformation of coarsely grained metal is quite iu,.omprehensible.

This, for some ~-eason or other, was not observed by Finkell,, (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) weakaning of the secondary extinction effect due to the increase of the degree of disorientation of the blocks within the cryst-~~llites. This means t]3&,t a metal can be characterised by coarsely grained structure and still not show any .secondary extinction effect if only the struoture of the crystallites is sufficiently close to the ideal, and that the secondary extinction effect can be considerable even in finely grained metals if only the cLegree of disorientation of the blocks within each crystallite is sufficiently smalls The character of the variation of the line intensity will depend on Card 3/12 whether the primary or secondary exi.-,inction only, or O-Till 26-6 -.4-28/34 1~s Paper Discussion on V.M.Finkel Coarsely and Finely Grained Steel Card 4/12 on "Cryst-al Lattice Distortions in During Cold, Plastic Deformation" both these effects take place in a polycrystalline metal specimen. It is easy to show that, as was postulated b~r 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 o~rerlooked by Finke!Q On the other hand, the presence of secondary extinction (Ref-5, 6), partioularly when the conditions are favourable for the formation of texture (Ref.7)*, the variation of the lines intensity can be quite different. For this reason Finkel's cc-r-tention that the observed effect was caused exclusively by the secondary extinction is no-h quite justified.. since in the case under considerat,ion the effect of texture might have been the predomin nt factors (iv) The difference (not much larger than the limit of the experimental error) of the values of in the (310) aind- (211) directions can be attributed not only to the anisr-tropy of the distortions of the lll,..:ai type. but also to the SOV/126-6-4.28/-34. - Discussion on V.M.Finkell's Paper on "Crystal Lattice Distortions in Coarsely and Finely Grained- Steel During Cold, Plastic Deformation" difference between the depth of penetration of the Co- and Cr-radiation. 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 pro-wed only by further experimental work. There are 9 Soviet references. ASSOCIATION: Petrozavodskiy Gosuniversitet (Petrozavodsk State University) SUBMITEED: 28th January 195?. Reply by V.M.Finkellstates the following: In spite of the "coarsely" and "finely" grained structure of the experimental steels, the size of the regionz of coherent d~.sp~rsiou 1-u steel 3 did not exceed. i.? x 10-5cm at 2% deformation wid 1.1 x 10-5cm.at 4% deformation. In the case of the heat-treated rail steel, the size of the mosaic blocks was smaller by one Card 5/12 order of magaitude (e.g. 2 x 10--6cm at 10% deformation). SOV/126-6-4-28/34 Reply by V.M.Finke2 Consequently~ the observed phenomena cannot be attributed to the effect of primary extinction in either case since primary extinction -is practically non-axistent at the size of the regions of coherent dispersion quoted above. (Ref.3., 4). To account for the stab-11ity of the intensity of the (310) lines. one has to assume that its decrease due to the effect o� micro-distortions of the 111-rd type is counter-balanced by an opposite effect of some other physical factors. auch as secondaa-7- extinction and texture. The seconday~y extinction can, in all probability, display itself th:coughout the whole deformation range: in its initial stages it is associated with the process of block fragmentation and J the resulting disorientat -Lon of the mosaic blocks, in the later stages it is caused by the process of disorientation not directly connected with the block fragmentation (Ref-5). Unlike secondary extinction, the effect of primar7j extinction (in a coarsely grained aggregate), being associated with the process of Card 6/12 fragmentation only, probably disappears in the initial Reply by V.M.Finkell 1Z OV/1 2_6 6 - 4 - 28/3 11 stages of the deformation (b_aving 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 magaitude larger.than that in steel. so that the mnyimum. on his curves is obviously associated with-the effect of the primary e3ctinction. When a high caroon 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 disorientation. ThAs minimises or possibly even eliminates secondary extinction, which would explain the differez~,t character of the variation of the lines intensity with deformation in annealed and quenched specimeaus 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.7), Iu add- uion, had the observed phenomena been attributed to the effect of tsmtuTe onl-j, Card 7/12 it would imply that the chaEacter of the texture in SOVI/120- 6-4-281/34 Reply by V.M.Finkelf steel .3 and rail steel is basi-ally diffeient (since in the former case 1(310) is C:Fnstant and 1(211) increases 'With increasing degree of deformation, while in the latter case both 1(310) an(' IJ211) decrease) which, of cours6. cannot b6 true. IU is difficult to understand v~ay SJ~ivrin should be surprised by the fact that the background intensitT in defor-med steel 3 did not change: The variation of the baokground intensitT in the high carbon content, rail steel did not exceed 7-8%. It is only to be expected tiiat it should. amount to less in the case ofo steel 3 i-il wh~ -ch., owing to its low carbon content,*the la-k-Itice di~stortions caused by deformation are much smalle-r -,I-;aa those in steel 3. Since the variation of the. bac"Kga-o~ind intensity is generally small it cannot be used as a practical criterion of the degree of lattice distortion.

The heavily deformed surfa(~e layer was removed by etching in a mixture of HN03 and HCI; it was found that the struotural distortions were the same throughout each specimen. The specimens were relaxed in a tubular furnace at 300, 350, 400 and 450 OC by soaking for a period of from 10 minutes to 20 hours, depending on Card 115 temperature.

This method has the disadvantage that the preceding metal layer is always dest-oyed and no general picture of the structural changes can therefore be considered. The diagonal cut method allows repeated measurements on the same sample and is widely used for investigations of the surface hardening for the determination of microhardness (Ref 1). In the case under review the last mentioned method was applied with some modifications to roentgenographic investigations of the surface hardening that occurs on turning steel 45 and brass L 62. The cut was made Card 1/2 under a small angle (10), and.the cut surface on the steel Investigation of the Surface Cold Hardening With SOV/32-25-5-13/56 the X-ray Photography Method by Means of the Diagonal Cut was first polished with aluminum oxide and with GOI pastes afterwards. On the brass samples the cut surfaces were prepared by milling and subsequent polishing. Roentgenograms were taken along the cut surfaces with the 1-KROS camera. Measuring results of the variation of the line width (211) of ferrite on steel samples 45 which were turned at different cutting speeds (Fig 1) show the thickness of the hardened layer to be always larger than 0.5 mm. The distribution of microdeformations in the surface layers of brass (Fig 2) differs from the one on steel, which is explained by phase transformations at higher cutting speeds (i.e. higher temperature). There are 2 figures and 2 Soviet references. 01 ASSOCIATION: Petrozavodskiy gosudarstvennyy universitet (Petrozavoi--w-L State University) Card 2/2 16 1 G 0 , 18- 20 0 AUTHORS: Snlvrin, 0.

The difference in granularity was attained by means of a corresponding heat treatment. In the first part of the paper, the heat treatment of samples of the grade steel CT.20 (st. 20), their preparation for the experiments, and the experiments themselves are described in brief. The second part contains the results, which are discussed. It is shown.that neither in coarse- nor in fine-grained steel of the grade investigated, any influence could be found to be exerted by the weakened surface layer on disoriented macrodeformations (that would have led to a macrohomogeneity of the micro- deformations). The experiments also showed that the microstructure exerted Card 1/2 The Problem of the Macrohomogeneity of Micro- S/170/60/003/005/015/017 deformations and the Existence of a Weakened B012/BO56 Surface Layer a very slight influence upon the dependence of the disoriented micro- deformations upon the crystallographical direction. It is pointed out that ID this is in accordance with the fact that the anisotropy coefficients are V independent of the degree of deformation, which had been shown to exist in the papers of Refs. 9, 13. It is declared with some caution that the anisotropy coefficients are rather universal, and are constant for the material concerned. There are 3 tables and 13 references: 12 Soviet and 1 British.

In continuous polycrystalline specimens, texture also has an effect which has led to many investigations being carried out on powders. However, such investigations cannot solve important problems relating to continuous specimens, e.g. in which structural disturbances are responsible for metal strengthening in plastic deformation. Their present brief work (for Shivrin a continuation of previous investigations - Refs-3,5 ) deals mainly with continuous specimens, especially the development of techniques to give reliable results. It had been concluded (Ref.3) that for deformed steel, copper, brass and aluminium, secondary extinction predominates in the annealed state. To check this an annealed Card 1/3 S/126/60/010/004/013/023 Elll/E452 Structural Disturbances Producing Changes in the Intensity of X-Ray Interference steel was investigated with a view to quantitative treatment of extinction. One specimen (of type 45 steel) was heat-treated to give a fine-grained, and another to give a coarse-grained structure. Patterns were obtained with filtered Co KC, radiation. The ratio of the theoretical to the experimental integral intensity is plotted against the value of the specific reflecting capacity. A linear relation was found for both specimens (Fig.1) indicating absence of primary extinction. Block disorientation was calculated from these graphs. Results differ from those of V.I.Ivernova et al.(Ref.12). A material very different from those previously studied is tungsten. The authorslattempt to study monolithic specimens failed. The results for various powder sizes agree well (Fig.2) with those calculated by Darwin's equation. The absence of type-III disturbances is attributed to the exceptionally high brittleness of tungsten. There are 3 figures and 12 references: 7 Soviet, 4 English and 1 in Acta cryst.

Observations of lunar radio emission at a wavelength X = 2.3 cm, using the large Pulkovo radiotelescope PERIODICAL,,, Izve5tiya vysshikh -,jcliebnykh zavedeniy, Radiofizika, 1961, Vol.4, No.3, pp.428-432 TEXT~ It has been shown (Ref.-I-, V.S.Troitskiy, Astron.zh., 31, 51-1 (1954)) that measurements of the brightness temperature at the zentre of the lunar disc permit an estimate to be made of the equivalent -zonductivity of the lunar surface material. Such measures, carried out over the -,ourse of a lunation, demand great stability of the instrument used, In order to minimize the stability requirements, the antenna temperature was determined indirectly by measuring the displacement (x) of the centre of gravity of the emitted lunar radiation from the geometrical centre of the Moon, Using this met-acd, the amplification coefficient of the system only has to remain ~-onatant during the course of one observati-on, The use of the displacement x is discussed in the Card l/ S/14!/61/004/003/004/020 Observations of lunar radio E133/E435 paper of N.L.Kaydanovskiy and lvis team (Ref.2. Izv. AN SSSR, M., 1956, P~347)- The results iliere are inaccurate owing to the fact that the lower reflectivity of the Moon, towards the limb, was ignored, The antenna temperature is derived from the displacement in the way which ha8 been described by Traitskiy (Ref,l). Only the first harmonic term is retained in the present paper, The -variation of x Yrith the amplitude of the variable component of the brightness temperature at the centre of the disc is thuz obtained, The Lheoiy ul Ttoitoltiy assumes that the Moon's orbit lies in the ecliptic plane and that there is no libration. This approximation is applicable except near new, or full, moon. At these latter times, however, the displacement of the centre of gravity of the lunar radiation is small and, therefore, the deviations can also be ignored at these points. The authors discuss the use of an antenna with a low half-width in one coordinate and a considerably greater half width in the other coordinate (Fig.2). Su:-h an antenna can be used so long as the pattern is elongated parallel to the plane of the Earth-Moon axes, so long as it is trailE-d in a direction perpendicular to this. Observations of the Moon wer;_: inside in October-December 1959 at Card 2// 30753 S/ilil/61/004/003/004/020 Observations of lunar radio ... E133/E435 X =-:2.3 cm on the large Pulkovo telescope. The angular resolution of the antenna was 21 in one direction and 201 to 10 in the other. The observations were made with the Moon at upper culmination in order to fulfil the conditions mentioned in the previous paragraph. Fig.4 shows the variation of x with lunar phase. x = 0'.17 (Wt - 350), where t is counted from the new Moon. The accuracy of this expression is + 30%. The amplitude of the variable component at the centre of The lunar disc is, hence, derived as 13.5 + 40K. Acknowledgments are.expreBsed to S.E.Khaykin and X.A.Novysh.
