The twisting was porformod by stretching spirals (6 mm in diameter) made of wire of th6-,.investigatod motals (of diametors 0.23 and 0.5 mm respectively) at helium temporaturo. To produce compression,apecimons in the form of tin wires 0.1 -- 0.2 mm in diameter and approximately 30 mm lomg were compressed between glass platos. Curves are given to illustrate the of- fecto of the deformation.

TITLEt The Low-Temperature Polymorphism of Metals (Nizkotemperaturnyy polimorfizm metallov) PERIODICALi Zhurnal eksperimentalinoy i teoreticheskoy fiziki, 19589 Vol 35P Nr 3, pp 802 - 804 (USSR) ABSTRACTs In the present paper (unlike the pr aotioe adopted by several earlier papers dealing with the same subject) the method of mechanical tests is used, in which the compression diagram of lithium, sodium, cesium, bismuth, and beryllium samples with subsequent heating are investigated. Also the varia- tions of volume in inverse transformation are recorded. These tests were carried out on a one-ton machine with a rigid dynamometer, which is suited for carrying out measure- ments at helium temperatures. The velocity of deformation was constant and amounted to 0,03 mm/sec. A graph gives a typical diagram of the deformation in the coordinates "stress absolute compression" for lithium. At 771DK this is the melting curve with consolidation of the shape at high degrees Card 1/3 of deformation. There are no singular points indicating a The Low-Temperature Polymorphism of Metals SOV/56-35-3-46/6i transformation. If the deformation temperature drops to 200K and less (down to 1,4 0K), a characteristic discontinuity is observed on the curve with a sharp decrease of resistivity against deformation. The most direct proof of the polymor- phous transformation in the tests discussed are the variations of volume in inverse transition while the deformed sample is being heated. Similar curves were obtained also for sodium. In the case of cesium no polymorphous transformation is observed on the deformation diagram even at 1,4 0K. Neverthe- less, the shape of the curve of heating allows us to conclude that, to a small extent, such a transformation actual.17 exists. This behavior of the three alkali metals is apparently ocn- nected with the reduction of characteristic temperatui,@e and leads to the conclusion that polymorphism exists in the entire group of alkali metals. The discontinuity of stress in th'e compression diagram is observed also in the case of beryllium at temperatures of 4,20K and less. All this seems to indicate an extensive occurrence of low-temperature poly- morphism, which is observed in the case of tin, sodium, lithium, cesium, bismuth, and beryllium. There are 2 figures Card 2/3 and 6 references, 4 of which are Soviet.

Absorption of Energy During Low Temperature Deformation of Nickel PERIODICAL: Uch. zap. Khar'kovsk. Un-t, 1958, Vol 98, Tr. Piz. otd. f1z.- matem. fak., Vol 7, p-p-35T - 363 ABSTRACT: The authors investigated the effect of the deformation temperature on the magnitude of latent Ni deformation energy within the tem- perature range of liquid N2 and room temperature. The following pulse method was used for measurements. Deformed and standard specimens were connected to a bridge circuit and current Vilses of a'short duration (0.01 - 0.02 see) were passed through. The pulse intensity was sufficient to anneal the hard-faced specimen. During the annealing process, due to the liberation of latent de- formation energy, the bridge balance dhanged; this served as a criterion to calculate the latent deformation energy, The error of measurement was about - 7%. The specimens consisted of wires Card 1/2 of 0.25 mm diameter and -150 mm length. They were deformed by P,1515 SOV/137-59-5-10790 Absorption of Energy During Low Temperature Deformation of Nickel compression between two plane parallel plates. It was established that a de- crease in the deformation temperature caused an increase of the latent de- formation energy from 0.53 cal/g at room temperature to 2.2 cal/g at 770K. The energy consumed for deformation did not remain constant,, but decreased from 17.5 to 5.38 cal/g, respectively, Consequently, during constant work the temperature dependence of the latent deformation energy will be still more pro- nounced. Results obtained confirm the assumption that relazation processes occur with sufficient intensity even at room temperature. In the investigated range of temperatures the linear dependence between the increment llp and the magnitude of latent deformation energy for Ni was established. L.B.

TITLE: Investigation of the Plastic Properties of Aluminium, at Low Temperatures (Iazledovaniye plasticheakikh svoystv alyuminiya pri nixkikh temperaturakh) PERIODICAL: Fizika metallov i metallovedeniye, Val 7, Nr 5, pp 794-800 (USSR) ABSTRACT: Pure aluminium (99.994A41) and technical aluninium con- taining up to 1% impurities (Si, Kn, Fe).were used for the investigation. The specimens were in the shape of plates of 2.5 x 2.5 mm cross-section and 17 mm wQrking length, widening at the ends for ease of grIpping in the testing machine. After grinding and polishing, all specimens were annealed in vacuum for one hour at 30000. The average linear grain size in pure aluminium was 1.0 to 1*5 mm, and in technical aluminium 0.3 to 0.5 mm. Deformation was carried cut In a vertical-tjS* tassile test1W machine using mechanical loading, being specially adapted for low temperature work. Card Tensile tests were carried out at 293, 77, 20, 4.2, 2.06 and 1/4 1.40K. In this apparatus it was possible to oarr7 out tensile and compression tests in liquid hydrogen as well as BOV/126---7-5-25/25 Investigation of the Plastic Properties of Aluminium at Low Temperatures. in liquid helium at 4.20K and below. A temperature of less than 4.2*K was obtained by evacuating helium. The layout of the apparatus is shown in Fig.l. A study of the macro- and microstruoture of fractured specimens has shown that the nature of plastic deformation of aluminium changes fundamentally with change in temperature from 20 - 4.20K and below. Fig.2 shows the microstrueture of an aluminium specimen (99.994%), fractured at 200K. Fig.3 shows the microstrueture of a similar specimen fractured at 4.26K. In Fig.4 the macrostructure of aluminium specimens (99.994% Al) fractured at 20011 (a) and 4.20K (b) is shown. In Fig.5 load-extension curves for cylindrical specimens of technically pure aluminium of 3 mm diameter (annealed at 3000C for one hour, grain size 0.3 mm) are shown for various temperatures. In Fig.6 load-extension curves for flat pure aluminium specimens of 2.5 x 2.5 mm section (annealed at 3000C for one hour, grain size 1-1.5 mm) are shown for various temperatures.

In Fig.11 the dependence of the mechanical roperties of aluminium on temperature In the range 1.4 to 29694 is shown. The authors arrive at the following conclusionst 1. It has been found that a sharp difference exists in the macro- and microscopic nature of plastic deformations of specimens of pure aluminium if the temperature at which they are strained.is changed from 20 to 4.20K and below. A lowering in the temperature of testing leads to an intensifi- cation of the inhomogeneity of plastic deformation; i.e. to the formation of large blocks the sizes of which exceed those of the average metal grain. 2. The plastic deformation of aluminium at 4*20K and below is characterized by an unstable flow which is expressed the Card 3/4 more clearly, the lower the testing temperature. Preliminary cold working of the specimens intensified the interrupted SOV/126---7-5-25/25 Investigation of the Plastic Properties of Aluminium at Low Temperatures nature of flow. 30 At 4,20K and below the formation of mechanical twins is observed in aluminium. It is possible that the instability of plastic flow is associated with the formation of mechanical twins. 4. The mechanical properties of aluminium in the temperature i@ange 77-1*4*K have been determined. It has been found that the true strength of specimens of pure and technical aluminium tested to fracture at 4.20K are close to one another. The ultimate tensile stress as is practically independent of temperature. The residual elongation has a maximum in the range 20 to 4.20K.

The specimens were Initially free from distortion and were deformed by uni-axial compression at both room temperature and temperature of liquid nitrogen. The latter samples were investigated in a low-temperature X-ray chamber (Figure 1). The specimen was partly immersed and also sprayed by 0liquid nitrogen, giving a variation of less than +-0.2 . An approximate method (B. Ya. Pines - Ref 8) ;as used to distinguish between the effects of "fine dispersion" and'Inicro-distortion". Figure 3 shows that even at small deformations (2-5%) a fine dispersion is -developed with coherent regions of Cardl/3 approximately 10-5 Cm.

Similar curves were obtained for lead. These show that the main effect of distortion of the crystal lattice is obtained at the very beginning of deformation. Deformation at low tem- peratures proddees more micro-distortion than at room temperature. Curves of relative micro-deformation at low temperature are shown in Figure 6. These show it in inhomogeneous and passes through a maximum. Thin ciaxi increases with increasing deformation and decreasing tempwature. Micro-stresses in the samples were calculated and an attempt was mad-e to relate them to creep limit. It was shown that the micro-stresees are always less than the creep limit. Figure 7 shows that a linear relation-hip exists between the micro-deformation of the lattice and the creep limit. A similar relationship occurs with Card 2/3 SOV/126-8-2-12/26 X-ray Study of Deformation of Metal Crystal Lattices, Deformed at Low Temperatures hardness. From the obtained data, the mean values of the elastic energy of deformation were calculated.

These values are only small percentages of the total latent energies of deformation - There are 7 figures and 14 references, of which 10 are Soviet and 4 English.

A more detailed study was intended of the nature of the dependence of these factors on the deformation temperature in a wide temperature rangep particularly at small deformations. Massive specimens of technically pure aluminium and spectroscopically pure lead were plastically deformed by uniaxial compression at 90, 1952 255 and 293 OK, Immediately after deformation2 without intermediate amealingg the s ecimen was placed in a low-temperature &amber (see 9ef 1) and its X-ray Card diffraction pattern was photographed. It was kept at 1/)+ liquid-nitrogen temperature during the X-ray exposure in order to exclude the influence of relaxation. X-ray 67751"" JOV/126-8-5-9/29 X-ray Crystallographic Study of the Temperature Dependence of Metallic Crystal Lattice Distortions irradiation was carried out by the inverse exposure method in a copper radiation with a sharp-focus X-ray tube having an adjustable focal spot. The (511) lines of aluminium and the (620) lines of lead were studied. The average linear size of the coherent scattering regions and the micro-stresses were found by harmonic analysis of the shape of interference lines. The method of X-ray irradiation and treatment of results has been described more fully by Golik et al (Ref 2). In Figs la and 2a the dependence of theaverage linear size of the coherent scattering regions D on the percentage deformation is shown graphically for the investigated metals at the above temperatures. In Figs lb and 2b the dependence of the average linear size of the coherent scattering regions on deformation temperature is shovm. In-Fig 3 the.same dependence.is shown for aluminium.

The average percentage deformation e was calculated by graphic integration,, and averaging along the depth of the column (600 and 800 A for Pb and All respectively), A graph representing the dependence of this factor on the degree of deformation forlead specimens deformed at various temperatures is shown in Fig 4.

According to M.A. Bol'shanina (Ref. I - Ivz. AN SSSR, ser. fiz., 1950, 14, 223) plastic deformation of metal does not only cause formation of crystal-lattice distortions but also leads to their elimination. According to published work a sufficiently high deformation at room temperature in Al and Au leads to a decrease in the concentration of the excess vacancies. Data are given in this paper on the influence of deformation.at the rate of 1005Vmin and 105 9'./m:Ln (impact) at 20 and -196 OC,on the increase in the resistance caused by preliminary quenching. The investigations were made on 60 mm long, 0.05 mm dia. -urire, made of pure gold (99.99%), which was determined by compressing the wire with two polished steel plates. The quenching was by rapid submersion of the specimens in water. Fig. 1 shows the dependence Card 1/# Influence of the .... S/126/61/012/003/020/021 E073/E335 of the relative increase in the resistance as a function of the rate of deformation for specimens which were annealed prior to the experiments (Curve 1) and for specimens which were quenched prior to the experiments (Curve 2); these curves were obtaincd at low rates of deformation at room temperature. In -the medium range of deformation rates intensive elimination of vacancies occurs and at high rates of deformation excess vacanGies are completely absent And the process of deformation is practically the same in -the quenched and annealed specimens. FES. 2 shows' similar curves plotted for specimens which were deformed by impact (rate of deformation 105 %/min) at room temperature. In spite of the possibility of the specimens being heated during the process of deformation, an appreciable elimination of the vacancies occurs at considerably higher rates of deformation. Curves are also given in the paper for specimens deformed at -196 OC; at this temperature practically no elimination of vacancies was observed.

Therefore, the authors investigated: the influence of excess vacancles and dislocation loops an the Hall "constant" R; the ratio of the potential of the Hall field 9 to the potential in the longitudinal d1rection of the specimeA EX; the relative change of the electric resistance in a magnetic field Ae/P(O). They confined their investigations to the range of weak and intermediate magnetic fields H < H 0, where H 0 is the magnetic field for which the radius of the electron orbit is equal to the length of the free path. The measurements were made at the hydrogen temperature using fields up to 3.5 kOe. generated by reversing the polarity of a permanent magnet.

Defects of a specific type were produced by quenching the aluminium from near-fusion temperatures in methylated spirit which had been cooled to a temperature approaching the solidification temperature. Due to coagulation of the vacancies during annealing at room temperature,, dislocation loops with a density up to 1010 cm -2 were produced. The curves of the changes in the electric resistance of aluminium in a magnetic field proved to be in good agreement for the following specimensi hardened as described above; aged at room temperature; annealed at 600% for 90 to 120 min, This confirms that the K'O'hler rule is fulfilled for the given range.

TITLE: A new induction method of measuring electrical conductivity PERIODICAL: Pribory i tekhnika eksperimenta, no.1, 1962, 189-igi TEXT: The electrodeless inductive method of measuring electrical conductivity described here has definite advantages compared with the usual methods. It permits a comparatively quick measurement of the electrical conductivity of solids and liquids over a wide temperature range. The sample is supported at the end of a.straight metal wire about 80 cm. length from a magnetic suspension. Near the upper end of this -s-rire is an aluminium rotor by means of which a rotary motion is communicated to the system. The sample is in a magnetic field and its temperature can be altered'over a.wide range by meaijs of a furnace. The-whole arrangement is evacuated to a pressure of about lo-5 mm Hg. It is shown.that the electrical conductivity a is given by the expression: Card 1/3 S/120/62/000/001/049/061 A new induction method E039/E485 15 C2, (3) H TR7 0 where I is the moment of inertia of the system, R is the radius of the sample, Ho is the intensity of the magnetic field and w its angular velocity, c is the angular acceleration of the sample. Electrical conductivity measurements were made for copper, tin, zinc and aluminium and also of the thermal resistance coefficient for aluminium on cylindrical.samples-of different diameters. The results show that at the 'working frequency of the system and for samples of radius up to 1 cm, the influence of the self induced current does not introduce a noticeable error. The values obtained are.in good agreement with the accepted values for these materials. Analysis shows that the absolute accuracy of the method is up to 0.1%. The method is suitable for the easurement of electrical conductivity over the range-10- T to 108 ohm-l cm-1. There is 1 figure. Card 2/3 S/120/62/00o/ool/o4g/061 A new induction method'...

It was eptablished that dependence. of the mean dimensions of the regions of coherent scattering on the time of the isothermal treatment was non-monotonic. The magnitude n of the microdeformations of the lattice decreases monotonically i the process of relaxation. Specimens were first annealed at a high temperature to otabilise their structures and were then deformed by a maximum of 60-659;- at liquid nitrogert temperature, applying uniaxial compression with a constant loading rate.

At this temperature, the lattice constant of the light isotope 6 a (a(Li 3.5iO7.t 0.0009 R) is by 0-0015 R greater than that of the 7) heavy isotope (a(Li - 3-5092 + 0.0006 R). The relative difference in the volumes LVIV is about 0.1%. It has been shown for Ni isotopes that this difference between the lattice constant of the light isotope and that' of the heavy one becomes less at higher temperature, and may even turn I zero and reverse its sign. Consequently, the,iootopic effect in Li should@' be more distinct at low temperatures. In order to verify this the authors Card 1/3 3/056/62/042/003/049/049 Temperature dependence.of the ... B106/B102 took a number of X-ray diffraction patterns of the Li isotopes at 20) 70, and 3000K. Low-temperature exposure was made in a cryostat in which specimen and film were either completely (liquid hydrogen) or partially (liquid nitrogen) immersed in the cooling liquid. The X-ray beam entered the cryostat through plane beryllium windows sealod into the walls of a dewar. The diameter of the casing was 57-3 mm. The accuracy of determina-1 tion (A a . + 0.001 R) was not high enough to state the difference in the lattice cons-tants of the Li isotopes at room temperature. At low tempera- tures, however, this difference was clearly expressed: 0 a( 6 7) T = 20 K Li ) - 3-480 a(Li - 3-478 6 7) T - 780K a(Li ) - 3-483 a(Li - 3-482 The nature of the bonding forces in the lattice obviously has a decisive influence on the isotopic effect. In metals this effect is much weaker than in crystals with purely Van der Waals bonding forces.

These treatments introduced nonequilibrium vacancies which significantly af- fected the magnetic resistance Ap/po (where pois the specific resistivity of aluminum in the absence of a magnetic field at 20 and 110K).

Measurements of -AP/P0 = f(H2) were given for the quenched and deformed samples after aging at 2900K and. roan temperature. The magnetic results were plotted on a Korel diagram and little of the data deviated from the universal curve. Only after 50% deformation at 761K did the data deviatte significantly; however, after aging at room temperature for 250 hrs or at 4730K for 30 min, the deviation disappeared. A correlation was made between the Hall coefficients and the Korel rule, i. e., R-Ro = f(Hp k/P ot) where R = lim K is the Hall constant and Pk/Pot is the ratio of specific resistivity U-0 at room temperature to that at the measured temperature. The value of Ro extrapolated to zero field. These experiments confirmed that the symmetry principle of kinetic co- efficients depended on the crystal lattice defects.

In this work, the influence of the decomposition of the K-state was studied in terms of high temperature strength. The temperature dependence of electrical resistivity was obtained as a function of temperature and heating rate. For each alloy, the resistivity in- creased initially and at 5000C reached a peak, whereupon it dropped to a minimum (about 7000 to 9000C depending on the alloy) and rose again. The drop in resisti- vity was associated with the decomposition of the K-state. Deformation by compres- Sion (60 to 70%) in the temperature interval from -196 to +200C showed that the do-, composition of the K-state was practically independent of deformation temperature. At higher temperatures (between 5000 and 100000 and at high rates of heating the decomposition of the K-state was studied by increasing the heating rate to 101 deg/min. The interval for the maximum decomposition was displaced to higher tem- peratures (300 to 4500 higher), depending on the type of alloy. In the K-state re- gion a significant strengthening was also noted when the speed of deformation was increased from 0.03%/mip to 0.3%/min, while in the region of X-state decomposition no effect on strength @;as apparent. For fast heating rates, the rise in strength was maintained at higher temperatures than for slow heating rates. In.particular, for Ni-Cr this rwgion was expanded to 7000C, while for the other alloys to WO or 10000C. Where the K-state was decomposed at ix= temperature, no additional strong- thening occurred upon pulse heating. Orig. art. has: 4 figures. SUB CODE: 11/ SUBM DATEt 06AuSG4/ ORIG RM 011/ OTH REF: 003.
