TITLEi Exchange of experience PERIODICALs Zavodskaya laboratoriya, v. 27, no. 9, 1961, 1166 TEXT: A special apparatus was designed by the authors to study the deformation of specimens caused by repeated quenching (see Fig.). Tube 3 of heat-resistant steel is inserted into furnace I and quenching tank 2; specimen 4 is moved in this tube. The time of heating and cooling is regulated by drum 5 which is mounted on the motor shaft. When the drum is rotated, relay 6 reverses the direction of rotation of motor 7, on the shaft of which disk 8 is fixed. A special arresting device stops the disk after every individual rotation. Counter 9 records the number of cycles of thermal treatment. The apparatus was used for studying the deformation of aluminum, silver, gold, and platinum specimens on cyclic quenching In vacuo. Vacuum oil was filled into tube 3 sealed at its bottom end; furnace 1 and disk 8 were put into an evacuated vessel.

The Hc increased during the annealing, from an initial value of about Ir oersted to 10 oersted after 6 hrs. in the case of the specimens tempered at 9000C or to 13 oersted after 16 hrs. in case of those tempered at 11000C. It is assumed that the increase in H is caused by the action of dislocat- ion loops (generated by the inieractions between blocked dislocat- ions ana clusters of vacancies) whioh interfere with the motion of the domain boundaries; point vacanaies, although beinS very mobile, do not leave the crystal volume but acoumulate of the defeot sites.

One of the methods used in this study is Umt of paramagnetic S113cepti- bility, by means of which it is possible*to determine the inte"elationship between struc- tural changes and the states of phases, whether these changes are successive or simultan- eous, and to what extent they occur during the process of themal fatigue. In addition to the above methods the following were also use&- changes In tbarmal rigidity and card 1/3 ACCESSION NR: AT4010696 electrical resistance, form changes, and measurement of the surface electrical resis- tance with determination of losses due to eddy currents. The first task was the investi- gation of the effects of thermal stress on form changes and hardness of samples of the alloy subjected to cyclic heat treatment. The results obtaiied showed that the linear dimensions of alloys with high recrystallization temperatures did not change appreciably as a result of thermal cycles. It is interesting to note that after 250 thermacycles with cooling in water, breakage occurred without noticeable change in the length of the samples. Thermal rigidity of samples was measured in a standard VIM-IM apparatus. It was found that the changes in hardness resulting from thermal treatment depend not on ther- mal stresses but on changes in the fine crystalline structure of the alloys. The dependence of the electrical resistance of the alloy on heat changes during thermal treatment was studied by the potentiometric method using a standard PPTN bridge. It was found that resistance decreases up to 50 thermocycles. The absolute minimum occurs at about 325 cycles after which there is a continuous increase Vp to 600 cycles. 7hostudyof during heat treatment Were was a continuom Paramwetic suscepubulty showed that decrease in the hard'soludon d the fnetrix dAa to tha 6114)US QMDWfttg- TW4 Ptftess should cause a decrease In electrical resistance, The sharp biariso 323 O&G to Card 2/3 -wi- -mow- ACCESSION NR: AT4010696 difficult to explain. Por the exact explanation of the process Involved it is necessary to employ new methods using structural sensitivity characteristics and phase composition. Ile study of paramagnetic susceptibility demands a thorough study of structural and phase changes occurring during cyclic heat treatment. For measurements of suscepUbility a special unit was designed which utilized the compensatory method of measurement. The following conclusions were reached: cyclic heat treatment, with cooling In a stream of air, of thin sam ples 3 m m In diameter merely leads to acceleration of the aging process. With samples of complicated form a considerable stress gradient developed during heat treat- ment leading to an unbalanced redistribution of elements. Under these conditions the appearance of cracks is more probable. The study of paramagnetic susceptibility of the alloy showed that for 3mm samples susceptibility increases evenly. No anomalies were observed, a fact which Is explained by the almost total absence of a gradient of thermal stresses during cooling. Orig. art. has 5 formulas, 7 figures, and I table.

TITLEs Gas-Discharg4Stabilizer PERIODICALt Izveatiya Akademii nauk Armyanskoy SSR. Sorlya f1zik,,- matematicheskikh nauk, 1960, Vol.13, No-4, pp.65-.68, TEXT: The direct-current stabilizer described in (ref.1) consists cl a gas-discharge tube being within a solenoid which is series-connected with the discharge interval. The axis of the tube is parallel to the magnetic lines of force. In the discharge interval the anode-cathode charges move on spirals, i.e. they have a tangential component of velocity. Under the influence of them the gas begins to rotate 4n the tube. For an increase of the discharge current, the magnetic field increases, the trajectory of the charge strains in, the length of the spirals and therewith the resistance of the interval become greater. the current decreases. In the present paper the authors report on the measurement of the stabilizing coefficient. It is stated that it depends on the magnetl~ field and that it reaches a maximum for a certain field intensit Y" The coefficient is smaller than 3. The measurements confirm (in spite cf Card 1/2 83620 S102 60/013/004/004/004 C11 1YC222 eome deviations) the theory developed in (Ref.1). The velocity cf rc~ation of the gas in the tube and its Reynolds number were iic,-. determined. Hydrogen and argon were used as gases; here the result-4 d1ffered only by the fact that in the case of hydrogen the etabilization began for a somewhat greater voltage.
