VASIL'Yl-l', khozakillo 2.) 19 64. 430 F. 22(l) SOV/3-59-3-2/48 AUTHOR: Vasillyev, D.I.s Candidate of Technical Sciences, .0 1j" en~, - lef TITLE: Correspondence and Evening Education Needs New Orga- nizational Forms (Zaochnomu I vechernemu obrazo- vaniyu nuzhny novyye organizatsionnyye formy) PERIODICAL: Vestnik vyashey shkoly, 1959, Nr 3, pp 4-8 (USSR) ABSTRACT: According to the new Law on Consolidating the Contact Between School and Life and on the Further Develop- ment cf the System of Natiaml Education in the USSR, evening and correspondence education will play a para- mount part in the reorganized higher school. There- fore, the problem of how to better organize instruct- ion without the students having to discontinue their work is at present of great importance. The existing organizational forms of correspondence and evening tuition are, in the author's opinion, in a definite contrast to the scope which training-without-leaving- Card 1/4 employment has assumed at present. About 1 million SOV/3-59-3-2/48 Correspondence and Evening Education Needs New Organi z at i anal Forms people are being trained at the present time by the higher school correspondence and evening system, con- stituting 45.3% of the total number of students. The author doubts that the existing syz~,tem of evening and correspondence education can succv.-nfully copo with the task of training this great number of students to become highly qualified speciali.st:;. At present, the training of specialists staying on their job is mainly performed by correspondence instit,rt.,~:q. The majority of them have branches and traininr--~~onsultation points (UKP) all over the country, each Ise-"'4 ng several tens of thousands of students without having at their dis- posal the required training and na-~erial basis. Al- most all these vuzes are located in Moscow, Lenin- grad andKiyev. It is evident that they are unable to properly supervise such a wide net of branches and UKPs. At the same time resident vuzes, working under considerably better conditions, have noticeably in- Card 2/4 creased the number of evening and corresDondence I SOV/3-59-3-2/48 Correspondence and Evening Education Needs New Organizational Forms departments only in the last 2-3 years. It is appa- rently necessary to open correspondence and evening departments with resident vuzes for students uniting study and professional work. The author stresses a thorough change of the training process, suggesting that it be divided into 2 stages. The first one (courses 1 to 3) to provide education on general scientific and engineering subjects. For the second stage, evening and correspondence departments at- tached to special faculties should be established with the vuzes, where students would be taught the program of the fourth to sixth courses. The author suggests that the training literature for corres- pondenoe and evening students be printed in larger editions for which purpose a publishing office, "The Higher School" should be established. He also Card 3/4 recommends that radio, television and tape-recorders, SOVI'3-59-3-2/48 Correspondence and Evening Education Needs New Organizational Forms which are not being utilized in the training process, be introduced into the system of education-without- leaving-employment.

The bellows' is made of-stainless steel and is welded to the frame of the valve and the rod of the needle (see Fig. 1). The gap between the housing and the bellows is 0.4-0.5 mm, which permits the bellows to retain its rigidity at high gage pressures. A steel ball between the screw and the needle rod protects the bellows from twisting during the opening and closing of the valve. The needle, with a 40* angle, covers the 2 mm L __UDC_:__621AA6. 2 1, 17996-66 ACC NRt Ap f; ACC NRt AP6007846 0 1 SUB CODE: 14/ SUBH DATE: IlJan65/ ATD PRESS:,q 2/1- I AUIRIOR: Vasillyev, D. 1,,~ and Shallnikov, A. 1. /37 TITLE: Small Stream Flo -meter.

Vasillyev it is possible to follow directly the behavior of the matrix regions and of the .brittle skeleton in plastic deformation?and also to determine the structural stresses acting upon the A--region (of the matrix) and the B-region (grain boundariesIVnd mosaic blockd, hard phases). Between the residual microstresses di, the microstresses a , and the "structural stresses", the relation m or + a t - CY holds. The microstresses in turn are com- m s , posed of the microstreases a,. The stresses acting upon the ferrite of the carbon steel were experimentally measured for ste8l with 0.22%C in normalized steel and in steel tempered at 680 . The results illustrated in a diagram show the following: As soon as the fluidity area Is found, the structural stresses Card 1/3 acting upon the ferrite become smaller than the macroscopic q-"- On the Nature of the Fluidity Area of Pure Iron and Carbon Steels Card 2/3 67325 SOY/181-1-8-30/7J2 stresses, and this difference is conserved up to very high degrees of plastic deformation. When considering the disper- sion 4 cr at ,A ai, the sample exhibits regions in which the stress almost vanishes, in addition to the ferrite regions in which the stress is somewhat larger than a m. For the direct de-termination of the "structural stresses" 0acting upon cementit-- the authors used U-8 steel annealed at 760 . On a sample stretched by 10% it was possible to determine the average structural stresses a st of the ferrite and cementite. Immed- iately after the passage through the fluidity area, underloading of the ferrite begins with a considerable overload of the cementite, which fact sharply contradicts the Koster hypothesis. Apart from cementite apparently also the grain boundaries and the mosaic blocks play an important part by taking up part of the overload. In a metal containing either no impurities or which is subject to such conditions as prevent the formation of "atmospheres" around the dislocations, the curves of average structural stresses correspond to the macroscopic 67325 On the Nature of the Yluidity Area of Pure Iron SOV/181-1-8-30/32 and Carbon Steele deformation curve. The X-ray curves of deformation are smooth. If there are "atmospheres", the macroscopic curve of deforma- tion is a straight line in the initial stage of the process, and the structural stresses are not necessarily equal to the macroscopic stresses. The plastic deformation leads to a skeleton fracture. This, however, is no obstacle for the particles scattered into the materisl of the boundary-near regions in the way of taking up also the structural overload stresses, and to compensate in this manner for the underload of the weak A-regions of the matrix. A direct experimental hypothesis thus contradicts the Koster hypothesis where it holds that the cementite skeleton in the fluidity area of steel is unloaded. There are 3 figures, 3 tables, and 4 references, 3 of which is Soviet.

In the first part of the paper it is shown that a shift of X-ray diffraction lines occurs in the range of "rearward" angles of diffraction. In the second part of the paper the nature of equilibration of the residual miorostraine occurring in metals after macroscopically homogeneous and plastic deformations is investigated. Tests made with the following pure metals: a-Fe, Al, Cu, Mo, and Ni show that in all oases contracting residual strains which are independent of the sign of the preceding plastic deformation act on the matrix range. An equilibrium is reached in this system of miorostrains owing to the existence of grain boundaries and mosaic blocks which are under the influence of streaming microstrains. The ferrite and cementite in high-oarbon Card 1/2 steels were also found to be subject to miorostraine having On the Miorostrains Arising in Metals by Plastic Deformation.

The present paper describes a method of determining aligned microstresses, based on a macro-uniform and plastic deformation of polycrystalline samples. A method for the discriminating determination of macro- and micro-residual stresses is also given. For the angle plotting of small- dimensioned samples a camera was employed, based on the design Card 1/3 of the OK type, but featuring a shorter distance "camera On the Method of Radiographic Measurements of Macro- and SOV/32-25-1-30/51 Microstresses According to the Method of Angle Plotting aperture - film" (30 mm), as compared to the well known Kros camera (55 mm). A linear stress or compression of cylindrical samples leads to the formation of a homogeneous field of aligned microstrenses. The experimental X-ray analysis of this field calls for the sample to be cut to the shape of a rectangular parallelepipedon (Fig 2a). In the calculations the dependence of the relative change of the interface distance b6d on the square of the sinus of angle ~ between the d reflecting plane and the deformation axis is of essential importance.

The nature of microstresses can be explained by the hypothesis of "strong" and 11 weak" ranges offering a varying resistance to plastic deformation. If the various ranges of structure (grain) are regarded as such rangesp Greenough's (Ref 7) hypothesis is arrived at, which is, however, not confirmed experimentally (Ref 8). The stresses acting upon the range of structure in plastic deformation cang howevert be determined experimentally (Refs 6, 10)(Fig: Deformation diagram for steel 20 after hardening and tempering at 6800). in steel rich in carbon of type U6, the stresses acting upon ferrite and cementite (Refs 9, 11, 12) can be directly determined; thus, a natural explanation cf Baushinger's effect is obtained, and the hypothesis on the decisive importance of microstresses is quantitatively confirmed (Refs 119 13)- It is found that the method of "angular recording" according to Gloker is not Card 2/3 05M The Problem of t ~Clks6if ication and Nani1festation, of SOV/32-25-10-27/63 Residual Stresous.

TITLE: On the Part Played by Microstrains in the Process of Plastic Deformation of Metals 1~0 PERIODICAL- Fizika tverdogo tela, 1960, Vol. 2, No. 3, PP- 543-546 TEXT: The authors reported on investigations of microstrains occurring in plastic deformation of samples of JT-70 (L-70) brass and aluminum. Brass was homogenized for 30 hours at 4000C, aluminum (purity of 99-7 per cent) for two hours at 2500. The microstrains were measured according to shifts and widenings of the KaNi line 331 in the case of brass and according to the K.Cu line 333/511 in the case of aluminum. The elasticity limit 60.05 determines the resistance to deformation. Fig. 1 shows various characteristic curves drawn on brass samples. For aluminum (no diagrams are shown of these experiments) the greatest change in the properties investigated was observed in the range 100 - 2500C; do.05 had its maximum a+ 1000C. The course of the individual curves is discussed., It is Card 1/2 e 81368 On the Part Played by Microstrains in the S/181/60/002/03/27/028 Process of Plastic Deformation of Metals BOo6/Bo17 shown that ~he changes of various parameters occurring in the course of deformation can be divided into a "weak" A-range and a "strong" B-range (Fig. 2). The shift and the widening of the X-ray diffraction lines occurring in deformation are caused by mean structural strains ast / (lm and a dispersion of the structure A cret / 0, and they are a result of a varying resistance to deformation of the ranges A and B (which causes the line shift) and of the varying resistance to deformation of the individual A-ranges (line widening). After the macrostress has ceased, a field of microtensions is formed in the sample, which essentially influences the first part of the re-deformation curve. This effect becomes especially manifest in a sign change of load. There are 2 figures and 6 references: 4 Soviet and 2 German. ASSOCIATION: Leningradskiy politekhnicheskiy institut im. M. I.

TITLE: On the Problem of the Mechanism of the Formation of the LU"der's Lines and the Geometry of Plastic Deformation of Steel Specimens in the Tield Ledge Region PERIODICAL: Fizika metallov i metallovedeniye, 1961, Vol.11, No-3, pp.451-46o TEXT: The stress-strain diagram of some metals, of which steel is one example, is characterized by the presence of the yield ledge, i.e. a region within which strain continues to increase at a constant stress. This effect is associated with non-uniform deformation of the spectmen in the Initial stages of the plastic deformation process, On reaching the yield point, only a small portion of the specimen deforms plastically, this process continuing until the plastically deformed region attains elongation corresponding to the end of the yield ledge, When this stage has been reached, a region of plastically deformed material exists side by side with a region of undeformed metal, and the boundary between these two regions constitutes also a Card 1/9 21-923 S/126/61/011/003/011/017 Oit the Problem of ... E193/E483 boundary between two parts of the specimen which, now, have different diameters, These sudden changes of the diameter of the specimen not only cause stress concentration which promotes spreading of the plastic deformation to the yet undeformed regions but also give rise to surface marks, known under the name of Louderts lines, which do not disappear even when the mean diameters of the adjacent parts of the specimen become identical as a result of further deformation. A study of the process of deformation of the surface of a steel test piece, carried out by the present authors with the aid of high speed cine-photography, showed that the formation of 111der's lines is associated with the arrests of the front of the deformation region and with the appearance of new deformation nuclei, the arrests being probably caused by localized variation of the mechanical properties of the metal along the specimen. It is pointed out here that the formation of Lu"der's lines is independent of the nature of localized plastic deformation; irrespective of the physIcal causes of the latter effect, the very presence of boundaries between the deformed and undeformed regions and the periodic arrests of the deformation front are sufficient to cause the appearance of the LU'der's lines. Consequently, in Card 2/ 9 41,ee3 S/126/61/011/003/011/017 On the Problem of ... E193/E483 studies of the mechanism of the initial stages of plastic deformation, the analysis of the geometry of the process and of the physical causes of the localization of deformation is of fundamental importance, the nature of LUder's lines (which are merely an external manifestation of localized deformation) being a relatively simple problem. In this connection, the present authors discuss a hypothesis due to L.B.Erlikh (Ref.1) who has postulated that the surface layer of a plastically deformed specimen constitutes a "weak" region which deforms plastically under stresses, constituting 1/2 to 2/3 of the yield point of the material tested-, as a result, at the moment in which localized plastic deformation begins and the load, consequently, decreases, compressive stresses are set up in the surface layer of the tensile test piece, the surface layer loses its stability and "crumples", the resultant "creases" representing the LUder's lines. However, apart from the fact that LUder's lines are a volume and not a surface phenomenon (Ref.2) and that Erlikh's hypothesis does not explain the formation of Luder's lines on compressed specimens, the theory of redistribution of macro-stresses (during macroscopically uniform deformation) under the influence of the hypothetical Card 3/9 21223 S/126/61/oll/003/011/017 On the Problem of ... E193/E483 t1weakened" surface layer has not been supported by experimental evidence. Since, in addition, the very existcnce of the "weak" surface layer has not been experimentally proved, Erlikh's hypothesis cannot be regarded as having been sufficiently substantiated. The basis of the theory, postulated by the present authors, is provided by consideration of a tensile test piece which is being deformed by the mechanism of slip. If slip takes place in one direction only, and if the process of plastic deformation (taking place within the yield ledge region) is localized, deflection of the specimen axis must occur at the boundary between the plastically and elastically deformed regions. This is illustrated in Fig.1 which shows a specimen deforming by slip on planes at 45* to the specimen axis, the diagram showing the initial M and deformed (II) state of the specimen in a plane passing through the specimen axis and parallel to the direction of slip. In this case, elongation of the specimen takes place by parallel slip of-the adjacent crystallographic planes under the action of the maximum tangential stress. Since the interplanar distance during slip must remain constant, it follows from Fig.1 Card 4/9 S/126/61/011/003/011/017 On the Problem of ... E193/E483 that the relative deformation c is given by 4-4 cot 45* - cos (450 + COS (450 + 1) where tj and denote the length of the deformed part of the 2 specimen before and afterdeformation, and y is the angle through which the specimen axis has been bent as a result of deformati.on. For small y (measured'in radians) Eq.(l) becomes Y = Y (2) Y Similar relationship dl 7 d2 Y (3) dl Is obtained fr-om the consideration of the change in the diameter of the specimen, measured in the direction of slip. It can also be seen from Fig.1 that in the case of a cylindrical specimen, deformed Card 5/9 212 2 S/126/61/011/003/011/017 On the Problem of ... E193/E483 locally by slip taking place in one.direction only, the boundary between the elastically and plastically deformed regions (i.e. a.LU"der's line) represents an ellipse, inclined to the sp-ecimen axis at an angle of approximately 450'. This has been confirmed by the examination of a comparatively rare example of a-cylindrical tensile test piece, a part of which (approx. 10 mm long) deformed by slip in one direction only. An expanded graph of a LUder's line, formed on this specimen, is shown in Fig.2 (curve 1) together with a graph of a line (ellipse) formed on the surface of this specimen by a plane, intersecting it at an angle of 47*30'. Measurements carried out on this specimen showed that dj. = 9.55 mm, d2 =,9.40 mm and Y = 1003' = o.ol8,- hence c = 0.016 y which confirms the validity of Eq.(l) and (2) for the case under consideration. The geometry of deformation of cylindrical specimens In which slip occurs in more than one d1rection is analysed in a similar manner, and It Is shown that in this case the slip planes do not intersect the entire cross-section of the specimen. A nucleus of a deformed region "spreads" into the surrounding material'in a direction which does not correspond to Card 6/ 9 2122i S/126/61/011/003/011/017 On the Problem of E193/E483 the direction of any particular slip, but which is determined by the "interference" of all slips taking place at a given moment. As a result of this slip "interference", the material flows in consecutive layers on a complex, saddle-like surface whose intersection with the specimen surface produces a Ulder's line. Whereas in the case of "compact" te8t pieces (i.e. specimens of round or square cross-section) the Lu"der's lines appear as distinct, equidistant bands, the plastically deformed region of a thin, flat test piece is characterized by a uniformly roughened surface. Although the cause of this difference is still somewhat obscure, the present authors show that the formation of Luilder's lines within a plastically deformed region (as distinct from those which are an external evidence of the boundaries between the elastically and plastically deformed regions) are most likely associated with the arrests of the deformation front. Finally, experiments are described whose object was to ascertain whether slip takes place along the grain boundaries or within the graina. To thIs end, the number of grains per unit length was measured in two directions (parallel and normal to the specimen axis) before and'after deformation that had taken place within the yield ledge region.

TITLEs X-ray methods of studying plastically deformed metals PERIOD ICAL: Uspekhi fizicheskikh nauk, v- 73, no. 3, 1961, 503-558 TEXTt The present survey deals chiefly with structural distortions of plastically deformed metals, as become manifest by a change of position, shape, width, and the integral intensity of the lines. The methods first developed for the study of macrostrains under macroelautic stress are also discussed briefly. The present paper does not, however, deal witt studies concerning the various methods o 'f studying the mosaic structure and its effect upon metal properties, as this problem had already been studied by P. Hirsch (Progr. Metal. Phys. 6, 236 (1956). The present report is the first systematic description of the principal results available in the literature. In fact, the well-known survey by G. Greenough, (Progr. Me tal. Phys. 3, 176 (1952)) is concerned with publications until 1951 only. The lectures by Barrett and Green at the congress in Detroit (International Card 1/6 21229 S/053/61/073/003/003/004 X-ray methods of studying... B125/B201 Stresses and Fatique in Metals, Proceedings of the Symposium, Ed. by G. M. Rassweiler and W. L. Grubs, N. Y. Elsevier, 1959) contain only brief reports on some of the problems. The article by B. Warren, Progr. Metal. Phys. 8, 147 (1959) is an accurate survey of the totality of methods of harmonic analysis of the diffraction line profile. The present article is divided into the following chapterst 1) Shift of X-ray diffraction lines under macroelastic deformationss A. F. Ioffe and M. V. Kirpicheva sug- gested that the elasticity constants of single crystals be determined by measuring the lattice constants of a specimen under stress. Reference is made to papers by G. 1. Aksenov. M. Ya. Fuks used nomograms for in- vestigating steel specimens. This problem has been first studied by G. V. Kurdyumov and co-workers. V. Romberg supplied the formulas for the triaxial state of stress. D. M. Vasillyev and S. 0. Tsobkallo analyzed the "end effect" of the plane problem. The formula for a triaxial state of stress reads: a - ka E 2 W1 (1.8) T _L 1+p sin2T2 sin2 (P 1 Card 2/6 21229 S/053/61/073/003/003/004 X-ray methods of studying... B125/B201 where a-L denotes the stress in perpendicular to the surface. The coef- ficient k takes account of the effect of 11-L on the position of the X-ray lines. According to H. Mdller and H. Barbers, the use of elastic constants Em and % for the calculation of a. leads to a difference between ar and 6m. Vasillyev and Yerashev confirmed the hypothesis advanced by G. Greenough, Nature, 160, 258 (1947); Proc. Roy. Soo. A197, 556 (1949). According to B. M. Rovinskiy, the hypothesis of the boundary-near zones and of the inner parts of the grains explains the phenomena observed. The following conclusions can be drawn from the papers discudsed in the second chapter: The hypothesis of the "weakened" layer does not explain all of the phenomena observed. The hypothesis by Greenough yields values of ZN d/d (relative change of distances between the layers) that are by one order of magnitude smaller than the observed ones. The hypothesis of the weak zones of the matrix and of the strong boundary-near zones gives a satisfactory explanation of the phenomena observed. 3.

'According to G. I. Aksenov, V. A. Moshchanskiy, and several non-Soviet authors, the macroelastic deformation of a poly- crystalline specimen is bound to cause an insignificant reversible expansion of the X-ray lines if the elastic properties of orystallites are anisotropic.

The results of studies by V. K. Kritskaya, G. Gertariken, Ya. S. Umanskiy, V. A. Illina, and several non-Soviet authors diverge considerably. A paper by A. Kochanovska and a formula by Villkhinskiy are mentioned. D. BatruB1, V. I. Iveronova, G. P. Revkevich studied the nature of extinction in deformed metals. In deformed powders, the intensity of X-ray lines may vary due to the fol- lowing causess fragmentation of crystals, whereby extinction is altered; appearance of distortions in the lattice, associated with displacements of the atoms from their position of equilibrium (distortions of third kind), appearance of errors in the layer packing. M. A. Krivoglaz made critical remarks on a separation procedure. N. N. Davidenkov gave a definition of remanent distortions. 6. Data on dislocations resulting from the diffraction of X-ray lines.

TITLE: X-ray study of the initial stage of plastic deformation of polycrystalline metals PERIODICAL: Fizika tverdogo tela, v. 4, no. 1, 1962, 140 - 147 TEXT: The authors used an x-ray method to find out whether plastic defor- mation of Al, Ni, Cu, and steel with 1% Cr proceeds inside or along the crystal grains. The small specimens were deformed at room temperature on an~iM-4P(IM-0) tensile testing machine after heat treatment. The micro- scopic stresses can be found from the behavior of x-ray diffraction lines; with the aid of these microstressee and the macroscopic stress one can determine the structural strain acting on the grains. The microstre,13es in Al were determined by an investigation of the 333/511 diffraction line obtained in a K.,Cu emission while those in copper, nickel, and steel samples were determined from the 400(K 4.100), 420(K,,,Cu) and 21](K,,Cr) lines.
