In-Fig. 6, the increase in the width (PIO-3 radians) of the (211) lines is plotted against the degree of deformation at temperatures indicated by each curve. It will be seen that a maximum degree of polygonization is attained in the materkiil,extended to 9% elongation at 1 150 OC- if, however, a 0specimen in this condition is held under a- , , load at 1 150 C for 80 min, the X-ray reflections become more diffuse, indicating that this treatment brings about an increase in the dimensions of blocks.

Experiments were carried, out on 99.8on pure Pd test pieces, preliminarily annealed for 1.5 liours at 1 300 OC with an average grain size of 1-25 mm and 2 hardness of 42 - 44 kg/mm . The.creep tests were cond2cted in vacuum under stresses ranging from 2.3 to-7-0 kg1mm . In addi9tion to the determination of creep curves, photomicrographs of the surface of the test pieces were taken at regular intervals without interrupting the test; on the completion of each test a Card 14 s/l8o/62/ooo/oo2/ol6/ol8 Microstructural study ....

In the present work some specific features of the mechanism of this process are studied in the chromium-nickel-manganese steel and a Nimonic-type alloy. The treatment was carried out at 1000-1100 *C with rolling at speeds of 3-6 m/min to give 25-30% reductions; nucleation and growtkr of new grains being arrested by cooling in water. Resulting microstructures were compared with those produced by ordinary Card 1/2 Some peculiarities in the ... S/180/62/000/003/007/016 El11/El52 heat treatment. The authors conclude that in the course of the treatment studied a slip occurs accompanied by rectification of the crystal lattice in the zones of slip and in the adjacent regions. In addition, a diffusion displacement of parts of grain- boundaries also occurs. These segments, formed as a result of the emergence of slip planes Ont. grain boundaries, undergo diffusion. displacement similar to grain-boundary migration in a stress field. Slip and displacement of grain boundary segments cause serrated distortion of grain boundaries specific to the treatment, the coarseness of the serrations increasing with intensification of the diffusion displacement. As a result of the diffusion redistribution of the crystal lattice defects produced in plastic deformation, substructure sometimes appears; its preferential appearance at the grain boundaries indicates that plastic deformation is most intense there.

TEXT; The object of the present investigation was to study the effect of temperature and strain-rate on the deformation- induced structural changes in Ni.- To this:end,'tensile tests- were conducted oh 99-305-o' pure Ni (containing 0.59% Co, 0.06c."

The structural changes were studied by hot-stage metallography, entailing the use of a cine-camera, and by metallographic examination of extended specimens at room temperature. Stress/strain diagrams were constructed for specimens extended at various temperatures Card 1/4 S/180/62/000/004/003/009 Specific features of .... E193/E383 and the temprature-dependence of the stress required to provide a strain of 209,,, was determined. In addition, the temperature dependence of hardness of Ni was studied and the microhardness was measured in various zones of extended test piecesa The affect of various factors studied on the stress/strain relationship is demonstrated in Fig. 1, where the stress (0-, kg/mm Yis plotted against clon-ation (Eq %) of Ni specimens extended at strain rates of 0.5 - 0.6% per hour (graph a) and 600 - 800c,, per hour (graph -z>) attemperatures indicated by each curve. The results of metallo- graphic examination can be sumiiarized as follows: 1) metallo- graphic studies of the surface 0of extended specimens showed that deformation of Ni at 20 - 400 C at slow (0-5 - 8!1 per hour) rates of strain is reflected in the formation of microrelief in the interior of the grains, where evidence of cross-slip can also be observed. The deformation, as revealed by slip bands, is not 0 uniformly distributed. The formation of sub-boundaries at 400 C can be just observed and there is some evidence of relative movement of the grains. 2) The formation of intragranular micro- relief at 600 900 `C (at the same strain rates) is much loan Card 2/4 N j . S/180/62/000/004/003/009 Specific features of El93/E383 pronounced, the relative movement of grains becoming the predominant mode of deformation. Intorcrystallino cracks appear'.r.ind the formation of clearly defined sub-structures takes place, the sub-grains.tending to become more equi-axial as the temperature of deformation increases- 3) Deformation (at a slow rate of strain) at,*l 0000C is accompanied by a recrystallization whose onset can be-detected almost immediately 'after application of the load. No visible slip lines are formed but the formation of sub-structure can be observed even at- lo-w maCnifications. 4) Deformation by slip becomes more pronounced at all temperatures-studied at hIghor (6oo z 8oo% per hour) strain rates, with a 'corresporfdinf; decrease in the .degree of deformation in the Grain-boundary regions; the distri- bution of slip bands is very -nonuniform, there is a marked 0 refinement of the sub-structure, particularly in the 800-1 000 C range and recrystallization in the early stages of deformation at 80CL - 1 000 OC is suppressed. 5) In common with many other metals and alloys, Ni appears to be prone to hot.;-shortness in the 6oo - 800 OC range.

At the same time, pilot test pieces were heat- tre~'ted in the conventional manner by quenching from temperatures given in column 4 of Table 1.

Similar results were obtained for alloy t-,, which, however, reqxtiressupplementary study. The conclusions reached can be summarized as follows: 1) VTMO brings about substantial (in comparison with the conventional hardening treatment) changes in the shape of the grain boundaries and orientation of the grains,and markedly affects the condition of the solid-solution matrix. 2) Vj.',%10 promotes more complete dissolution of the second phase on heating and more complete,precipitation of this phase during agei-ng than the conventional heat-treatment. 5) VTMO brings about a decrease in the dimensions of the mosaic blocks (down to 0.05 It in the case of:.alloy A), this effect becoming less pronounced if higher temperatures or faster rdlling speeds are employed. 4) Quite large (up to 1 X 10-3) microstrains are set up in the alloy as a result of VTMO, ageing or quenching from relatively Card 3/6 S/126/62/oWool/olVoA The effect of ....

The beneficial effect of this treatment is associated with the preelpitation of a large quantity of the liardening-phase particles, with more favourable distribution of this precipitate and indirectly with the reduced size of the mosaic blocks.

Thin effect is due to a higher conceiitration of beryllium in the grain-boundary regions where - possibly some precipitation-hardening takes place during quenching.

Round bars, .16 mm in ~160'mm long,,were annealed at 1100C for 1 hr, cooled to 900, 8000 diameter and 700, 600, 500, 400i or Mi rolled at these temperatures with a reduction of ;25~, and water quenched. The specimenz verethen subjected to recrystallization annealing for 1 hr in a vacunm at 500-900C. Hardness tests and microscopic examination revealed that an increase in temperature of TMT increases the tem- persture of the beginning andetcl of recrystallization. For instance, In speci- mens rolled at room temperature recrystallization begini,at approximatelY 57.,c Card 1/3-_ L 111114-63 ACaSSION 0: AP3000491 and is completed at approximateli 650C. Corresponding figures for specimens rolled at 900C are approximately 66o and 740C. The temperature interval between the beginning and end of-recrystallization is not affected by the conditions of DO and remains approximately 75C for all conditions tested. The kinetics of recrystallizationvere studied at 600C in a vacuum of 10-5 = Hg. At this tem- perature a sharp.decreas6 of microbardness begins after approx te 1 hr I ima 1y n all specimens rolled at 20--.800C After 50 hr recrystallization was completed and microbardness dropped from the original 190-120 kg/= 2 to approximately 70 kg/MM2. In-specimens rolled at 900C the recrystallization proceeded at a much lower rate and was not comileted even after annealing 100 hr, when micro- hardness dropped from. approximately 120 kg/= 2 to 80 kg/= 2. The stress-rupt re tests at 600C under an initial stress of 10 kg/MM2 showed that rolling at 20'u 900C considerably improves heat resistance as compared with that of Ni annealed at 1100C. Specimens rolled at 20, 400, 800, and 90OC'had the longest rupture life. Specimens rolled at ~O and 700-900C had the lowest creep rate in the fAirst-stage creep. The total elongation in stress-rupture tests, which does not ' exceed 3-4% for Hi annealed at U00C, varied in TMT specimens from 15% (rolled at 5000) to 44a (rolled at 600 and 700C).

The present article includes data o--n the total elongation of nickei sampies when tested an the D4ASbv-5S machine ax 400- 109ffC and at rates from 0. to 800%/hr. The flat W mm nickel samples were 99 3% pure Rid had passed metallo- Frap~dc tests. The grain size variation was calculatea by 'te Rachinger equations. K)o,L---dt1on was measured on a PMT-3 table wita 130X magnification. The quantity and size of 1~ntezmr-ystalline fractures was alBo measured. The main variations in nickel grain shape ttL,4~ size for different testing conditions are shown in Figures and 2 of the Enclosure. An ------------ Q., I! ACCMION NR: AT4046869 Increase in the rate of elongation to GOO-800%Ar causes marked disintegration of the i;tnicture. By comparing the curves in Fig. 2, it may be seen that when the grains are furtl~er from the aurface, with elongation rates of 0. 5 to 8 %/hr, the grains become larger, at 600 ve Ale -800%/hr, the i3tructure disintegrates. Sliding along the g7rain boundaries was Oetermined on the nJokel samples under tension at 400 and 800C and a rate of 0. 5-0.6 %,/hr. On the basis of the data obtained it is concluded that at a rate of 0. 5- 0. 6 Jj/hr the highest qupmtity of crackB per unit sample length, the maximum average crack width In the direction of tension and the largest fraction of total elongation occur at 800C. Fu&,her away from the surface, these deformations drop sharply. The total. length of separate cracks was also cLiculated, being equal to 0.25 mrn at 400-600C and reaching 0. 11-0.6 mm at 800-900C.

They appLied tensile tests in a 10-5 mm Hg vacuum at 2-0, 400, 700 and 1000 C to 99.3~ Ni and Ni 4301p Fe specimens. At 20 and 400 C the plasticity of Ni specimens was 72 and 51% respectively. Deformed grains were characteristic of the microstructure. With temperatures at 700 C, plasticity dzxqTed to 15-6% but was restored during further temperature increase of up to 1000 C. Hicroexaminations showed the predominance of e(rdiaxial grains. Plasticity ic Ord WE" L 164h9-65 AccEssioN ma: Ar4o4m5o was also high in, the Ki - Fe specimen with negligible restoration at 1000 c. The authors propose a generalized diagram of changer. in the mechanism of failure of polycrystalline metals within a wide range of temperatures. The diagram should be adjusted in accordance with the purity and the nature of the material but otherwise it is applicable to many metals andalloys that exhibit a tendency towards hot brittleness and recryst ZationOduring high-temperature deformation. However, the rate of deformation has to be invariable within a wide temperature interval. Orig. axt. has,. 4 figures.

The recrystallization of Ni was characterized by an appreciable de- crease in hardness with time and a high initial hardness of the recrystallized sect~ions of the structure which also decreased as the holding perioa was extended. Speqimens reduced at high temperatures and specimens annealed for 3 hours wit4in the 500 to 900 C range were characterized by an analogous pattern of initi- a I 11~,gh hardness of the recrystallization section.

Material Card 1/2 M~ N.- 1. 24853-65 ACCESSION NR: AP4046099 although the level of internal stresses is considerably lower than in that workhar- dened part. With the formaticn of new grains, n-icrohardness decreases in both 'the new and the workhardened grains. Deviations from the linear relationship observed in the recrystallized sections when recrystallization is slight and in non- crystallized sections when it is appreciable, are attributed to the base layer. With a base layer softer than the object of investigation, the hardness values are lower and with a harder base layer they are higher. This relationship mav pre- vail in the beginning and towards the end of the process of recrystallization when small amounts of new grains and the remainders of non-crystallized old grains occur in the basic mass of the opposite structure.

The devices are divided into four types. To type I belong those in which indentation is produced at a high temperature but the size is determined at room temperature. Type 11 includes those.devices in which the indentation is measured at the temperature at which it is produced.- Type III.devices are similar to the type II ones, but include sighting attachments for precise locating of the indentations. Type IV devices are similar to'those of type III but also include a mechanigm for applying tensile stress to the specimens. Five different microbardness tester axe discussed (all previously described in the literature). The- performance of three devices in determining micro- hardness of iron in -the temperature range of 20--1300C is explained, and the r-4 1/2 T ACC NR, XP6005652~ experimental results are tabulated. It is concluded that the performances of the three devices are approximately the same. The equipment tested here has been described byl. Schenk, E. SchmiAtmann, H. Brandis, and K. Winkler (Arch.

The rods were given a preliminary annealing treatment of 3 hrs at 11000C -and subjected to high tempera- ture thermomechanical treatment.(HTTT) at 500, 700 and 9000C (6.7 m/min) which yield ,ed a series of samples respectively reduced by compression to 2, 5, 10, 15, 20, 30 and 45%. 'Some samples were tested In the annealed state and others after deformatioi at 200C. Experimental results are presented for both.brief and protracted tests for tensile strength at 4000 and 5000C. As the HTTT temperature increased, strength de- creased. Maximum increases (1.5 and 2 times) were observed for'HTTT at 5000C, and UDC: 669.24-15i.9 Card 1/2 L 11096,~,66 ACC NRt AP5026365 for cold working at 200C--fdr the more heavily deformed (40 to 45%) samples. The yield stress was also found to increase more than the tensile strength; the best treatments resulted in increasing the yield to tensile strength ratio from 0.3-0.4 to 0.8-0.95. For short time testing the same general results were obtained at a somewhat lower test temperature (40000. In the 100-hour tensile strength test, strengthening by HTTT was achieved after a deformation of more than 20%. At 45% de- formation, the 100-hour strength of Mi at 5000C rose to 25.8, 26.6 and 30.8 (kg/=2) following HTTT at 900, 700 and 5000C respectively; after cold working, to 31.5 kg/M2. These ialues reflect an increase of 50-85% in strength. A schematic diagram illus- trates the effect of preliminary plastic deformation at various temperatures on the heat resistance of metals and alloys. In no case did phase transformations or dis- persion hardening occur. The low.strength region In this diagram was for low defor- mation. Orig. art. has: 3 figures, 1 table.

The following alloys were studied in the Fe-Co-W system with addi- tions of'molybdenum, chromium, manganese and nickel: V27K25, V20MTK25, V27K25Kh4, V2TK25G4, V27K25N3, V20M7K30 and V2OM7K2O. Control tests were also conducted using R18 standard high-speed steel. The results were compared with the variation in hard- ness after two hours of annealing in,the same temperature range. The dispersion- 1hardened specimens were quenched after heating to 13000C and holding for 4 minutes, a ,then tempered at 600*C for 2 hours. Conventional heat treatment was used on the spea mens of R18 steel (quenching from 12800C, triple annealing at 5600C). The Vickers hardness was measured under a load of 1 kg on a UIMV-1 installation with heating in a vacuum to 20, 500 and 6000C with folloving measurements every 500 to 8500C.
