The aim of the investigations was to find methods of heat treatment which ensure high magnetic properties in hot rolled sheets of iron alloyed with 16% Al. The alloy~O 16 (Yu16),d corresponding to the American "alphenol", was produced in an open 100 kg capacity induction furnace using as charge materials pure iron and refined grades of Al. Prior to alloying with Al, the melt was treated with a vacuum of 10 to 15 mm Hg col,, for the purpose of decarburization and deoxidation. The metal was poured into metallic moulds and heated to 5000C. To eliminate thermal stresses and cracks, the ingots were cooled from 8000C with a speed of 80 to 90OC/hour. The specimens had the following composition in percent.- C 0.009, Si 0.38, Mn 0.03, S 0.002, P 0.004, Cr traces, Ni 0.04, Cu 0.02, Al 15.7. The hot rolling was by means of a 2-high mill in packets consisting of sheets of dynamo steel and of the Card 1/4 85961 5/126/60/010/005/005/030 E073/E535 Investigation of Heat Treatment of Iron-Aluminium Magnetically Soft Alloys alloy Yul6. Discs of 30 and 20 mm diameter were stamped from hot rolled 0.35 x 600 x 1200 mm pickled sheets. The specimens, consisting of 20 sheets, were air annealed in a silite furnace in the temperature range 800 to 1200*C, followed by cooling at a rate of 1000C to the quenching temperature, held.at that temperature for 30 min and then quenched in a 20% NaOH solution, water or transformer oil. The magnetic properties were measured ballistically, the electric properties were measured by means of resistance bridges. For determining the influence of the annealing temperature on the magnetic properties, the specimens were cooled at the rate of 1000C/hr and then quenched in the alkali from 600*C. An increase in the annealing temperature from 850 to 1050*C brings about art improvement of the magnetic properties. On increasing this temperature further, the magnetic properties will become somewhat poorer. An increase in the annealing temperature leads to some burning off of the Al. The quenching medium and the quenching temperature have a consider- able influence on the permeability and on the coercive force; the highest ji0 values were obtained after oil quenching from 650*C Card 2/4 85961 S/126/60/010/005/005/030 E073/E535 Investigation of Heat Treatment of Iron-Aluminium Magnetically Soft Alloys (annealing at 9500C) and 7000C (annealing at 10500C). An increase in the annealing temperature shifts towards higher temperatures the optimum quenching temperature from the point of view of 40. The initial permeability is considerably lower for specimens quenched in alkali and water. For obtaining high maximum permeabili- ties it is necessary to quench the alloy from 6500C (after annealing at 9500C) and 6oo*c (after annealing at 10500C). An increase in the annealing temperature and the quenching speed leads to a decrease in the optimum quenching temperature. In the case of oil quenching, the coercive force decreases with temperature up to 650-700*C. It was found that an increase in the quenching temperature and the cooling speed leads to an increase in the electric resistance and, consequently, to a decrease in the degree of ordering. An increase in the soaking time from 15 min to 3 hours during annealing and also of the cooling rate from 50 to 200*C/hr does not affect greatly the magnetic properties. The results show that with this alloy magnetic properties can be obtained which compare favourably with those obtained for an iron alloy with a 50% Ni content.

E073/E335 temperature and the appropriate curves show a pronounced maximum (or0minimum). The residual induction has a maximum at 20 - 40 C and shows little dependence on the heat- treatment conditions. At low quenching temperatures (400 - 500 OC) and high cooling speeds, the magnitude and the temperature stability of the magnetic properties are low. The highest initial and maximum permeabilities were obtained in tests at 100-120 and 40-60 0C after annealing followed by oil-quenching. Artificial ageing at 50 - 100 0C resulted in an improvement in the magnetic properties by 5-20%. The results have shown that heat-treatment, which leads to improved magnetic properties of the alloy, brings about a decrease in the temperature stability of these properties. An increase in the cooling speed during quenchin� narrows the range of operating teifipetatures; at 15&180 C an irreversible deterioration in th8 magnetic properties will occur., Artificial ageing at 50 And 100 C improves, and artificial ageing at 200-250 0C reduces the magnetic properties of the investigated alloy.

This is a description of its principle of operation. This motor has neither a conventional steel stator with a copper winding nor a massive rotor. It operates by using the principles of static electricity - the interaction of stationary electric charges. The disk does 6000 revs/min. Attempts were made to increase the speed of the motor by producing the rotor from different materials. The best results were obtained with plexiglass. The speed can also be increased by placing the rotor in a vacuum, thus Card 1/3 reducing air friction. The power of the motor can be increased by An, Unusual Motor SOV/29-58-9-26/3o placing it in a high-pressure chamber . In a fluid di- electric the nominal voltage is reduced almost by a factor of 10. As a compensation the speed is considerably reduced owing to the increased friction of the rotor in the fluid. The dieelartric motor is still anything but perfect. Never- theless it is capable of being used in practical work. If a vane is attached to it it may serve as a ventilator. If the shaft of the rotor is arrested by a spring this motor is transformed into an instrument measuring high d.c.tension. The angle of deflection of the rotor will be proportional to the potential applied to the electrodes. The high speed of such motors and the lackine of a commutator recommends such motors for use in gyroscopes. Although at present it may sound phantastically, there is no denying that in princ4ple such a motor could be used in connection with a radioactive electrostatic generator. There are 3 figures.

The cathodoluminencence of all the specimens ex- hibited a characteristic band peaking at 380-400 r4A.

In this connection, the temperature dependence of Ebr was investigated in this paper in the field of electric breakdown in various dielectrics with different dielectric. permeability. This were dielectrics of different polarization character, different and a temperature dependence of 6 , being represented by titanates of zinc ZnO TiO (F -30), of calcium CaTiO, (EE -130), of barium BaTiO (r- .10005 and by SBT (E .8oo).(The V"alue of 8: is referred t9 room temperature at a frequency of I kc). The maximal errors in the determination did not exceed 12%. Mean and maximum values for Zn, Ca and Ba titanates and for SBT are given on a table. The dielectric strength of the investigated polycrystalline dielectrics does not change with the duration of voltage application at room temperature (figure 2). A certain correlation exists between the temperature dependence of C- and the breakdown voltage (figures 3 and 1). A higher breakdown voltage corresponds to smaller values of,E , although the temperature minimum of E, and the maximum of 6 do not coincide.

The examinations of the theory of electric breakdown in solid dielectrios proceed from the conception of impact ionization by electrons in a mediuin electric fi-ld. The disturbance of electron distribution is a consequence of the avalanche-like accumulation of conduction electrons in the crystal lattice. The interrelation between electric dis- ruption and the polarization effect (frequency, effective ionic charge) can be caused by energetical losses of the conduction electrons on lattice vibrations. The effects of polarization on the magnitude of dielectric strength of the dielectric must be caused by the energetical losses of the electrons on the vibrations of the basic lattice ions (atoms) as well as of the ions causing a polarization accompanied by an high dielectric, permeability., Moreover a strongly effective field is in a position to modify the frequency of the basia ions into either direction, which will show in the energy losses of the conduction electrons,, From this viewpoint it proves to be extremely difficult to obtain an analytical representation of the dependence of dielectric strength on Card 3/4 dielectric permeability and makes necessary special investigations. On the Temperature Dependence of the Pulsed Dialectri(., 48-22-4-11/24 Strength of Some Polycrystalline Dielectrics The representation of the interrelations between dielectrio strength and dielectric permeability must be examined and proved with pure monocrystals, The authors performed experiments with polycrystalline samples- For this reason the here investigated dependence is rendered more complicated by secondary effects, as caused by macroscopic heterogeneity of the substance (crystallites', vitreous layers, pores etc.)~ A final answer as to the nature of the temperature dependence of dielectrio strength on dielectric permeability can presumably be achieved by means of experiments with mono- crystals.

Platinum electrodes, applied to the specimens by evaporation coating, proved to be the most stable. The samples were sealed into aluminum containers and- placed in special cavities in a heavy-water test reactor. The specimens in the container must not be allowed to screen one another. The specimens were 8ubjec-ted chiefly to slow and fast neutrons and to gamma rays.

In ord.er to irradiate the specimens with thermal neutrons with a low enough percentage of fast neutrons, teat channels in the reflector of the reactor were used. Cadmium filters were used to absorb the thermal neutrons, so that the effeat of the fast neutrons and of gamma-background alone could be'studied. All samples irradiated by thermal neutrons showed considerable beta and gamma activity. V. S. Vavilov and S. A. Gavrilov are thanked for discussions and collaboration. There are 2 Soviet references.

Diamond doping was carried out in a' ion-ray installation with a magnetic separation at a focusing angle of 180% Lithiuml and boron ions with an energy of 40 kev were introduced into the natural face of the crystal or into the cleavage plane perpendicularly to the crystallographic directionsi (111) and (100). The activation energy for lithitim was (0.29 1 0.01) ev and for borork I- (0.25 t 0.01) ev. Lithium-doped diamond has an electron-type conductivity, while ini boron-alloyed diamond the holes are the major charge carriers. Annealing of specimensi at 600C for three hours in an argon atmosphere had virtually no effect on the activa-; 1/2 ACC NRs AP6018580 tion energy of electric conductivity; the general resistance of the doped layer in- creased somewhat only in the case of boron. The acceptor and donor levels appearing in the forbidden band as the result of radiative defects are deep and have only a slight effect on the activation energy. With an increasing concentration of lithium, the activation energy decreases in the range of high temperatures as well as in the range of lower temperatures. These rules apply to the impurity band, in which the concentration of lithium is about 1020 cm-3. Ion bombardment makes it possible to obtain semiconducting layers of diamond whose electric conductivity can change by 5 to 10 orders, depending on the extentof doping. The energy level corresponding to the lithium admixture is separated by 0.29 ev from the bottom of the conductivity band, while the energy level of boron is 0.25 ev from the top of the valence band.

The in- strument is based on Gerdien's principle, employing two identical cylindric capacitorf as measuring units. The change of the zero point current is analyzed and shown to be caused by the charge of the metal electrode by coarse aerosols. A procedure for eliminating this effect is presented. Deviations due to air turbulence are shown to lower the magnitude of ion concentrations in the capacitors by approximately 8% and to influence similarly conductivity. Analysis of data obtained over the Ukraine, Siberia, and the Far East region indicated that the ratio 1+/X- > 1 in the lower layer of the atmosphere, decreases with an increase in altitude ' and changes to values below unity at heights depending on conditions.

The results of direct measurement of radioactive-fallout intensity on the continents and on the islands and the data on the cuncentration of radioactive fission products in the air above the sea surface and above the surface of dry land were also taken into consideration. On the basis of these data, it is supposed that the intensity of radioactive fallout over the sea surface is ater than over dry land. Orig. art. has: 5 tables and 4 figures.

Moscow, Izd-vo Nauka, 1966, 43-56 TOPIC TAGS: Mohorovicic discontinuity, earth crust,.deep seismic sounding, granitic layer, basaltic layer, seismic velocity , %5ZIalme- C//,3 UZ ABSTRACT: The results are summarized of deep seismic sounding conducted in 1960 to 1962 along a 300-km submeridional profile between Stepnoye and Bakuriani and a 700-km sublatitudinal profile extending along the axial part of the Transcaucasian intermountain region between the Black and Caspian Seas. Continuous, piece wise continuous and point profiling methods were used. The analysis of data shows that the Earth's crust, 32-km thick in the region of El'iehotovo, increases to 38-40 km in the area of Stepnoy-Nizhniy Kurp and to 42-46 km in the southern part of the profile. The boundary velocity along the Mohorovivic discontinuity determined in the area of Nabakhtevi is 8.4 km/sec. The depth to the top of the consolidated crust with a boundary velocity of 6.km/sec varies from 7 km in the Zaterechnaya Cord 1/2 ACC NR: AT6034504 Plain to 300-400 m at Rokskiy Pass. Although the interfaces within the crust were not determined, seismic data appears to indicate a layered structure. The thickness of the Earth's crust along the sublatitudinal profile varies from 40-41 km at the western end of the profile and near the city of Kirovabad to 47-49 km under the Dzirul'skiy. massif and east of Lake Dzhandar. The boundary velocity is 8 km/sec. The boundary velocity along the top of the consolidated crust is 5.8-6.2 kmfsec. The depth to the top of the consolidated crust varies from 0 (Dzirul'skiy massif) to 12-15 km in the area of Barda-Agdzhabedi. Two interfaces with boundary velocities of 6.7-7 and 7.2-7.5 km/sec were established within the crust at a depth of 10-20 and 30 km, respectively. Sharp variations were established in the ratia of the thickness of granitic to basaltic layers along the sublatitudinal profile. A downwarping of the Mohorovicic. discontinuity under the mountains along both profiles is noted. The results obtained are in qualitative agreement with earlier geophysical investigations. However, deep seismic-sounding data indicate a downwarping of the Mohorovicic discontinuity under the Dzirul'skiy massif, while gravity data indicate upwarping. The article contains 7 figures including a map showing the locations of the profiles, a rough seismic cross section along the submerldional profile, a seismic cross section along the sublatitudinal profile and three other seismic- geologic cross sections' of the same general area compiled from seismic and gravity data by other investigators.

Moscow, Izd-vo Nauka, 1966, 97-102 TOPIC TAGS: Mohorovicic discontinuity, earth crusts-seismic velocity, granitic layer, basaltic layer / r4UeQ_70-Zs ABSTRACT: The correlation method of refracted waves was used in the investigation of the structure-of the crystalline basement along a 60-km profile running between Anaklia and Zestafoni along the Rionskaya and Kolkhidskaya lowlands as far west as the Dzirul'skiy massif. A refracting seismic horizon with a boundary velocity of 5.7-6.3 km/sec was identified as the -surface of the crystalline 'basement. Several* blocks separated by subcrustal faults are found in the basement along the profile. Each block is characterized by a boundary velocity and probably by a slightly different petrographic composition. Although the scope of the investigation did not include a study of the structure of the subbauement, it was established that *the Earth's crust along the profile consists of 3 layers with layer velocities of LC~rd 1t2 -ACt - P4~- AT6034508 3-7.2 km/sec. The approximate depths to the interfaces are 3, 6, and 10 km. The gravity data were used in preparing a cross section showing the depth to the Mohorovicic discontinuity, which varies between 45 and 46 km along the seismic line. The article contains 4 more figures including a cross section of apparent velocities along the seismic profile down to a depth of 27 km.

In super-cooling the ~ phase of alloys containing 4 - 10 percent V, as well as during isothermal exposure of these alloys, the decomposition process also occurs by diffusion; how- ever, when alloys containing 6 - 10 percent V are cooled at a rate of 5 - 6 deg/min the process of the T assumes a non-diffusive martensite character. At identical cooling rates the W T in a 4 percent V alloy is of intermediate nature, but ctnges to a martensite nature when the cooling rate is in- creased. From the results obtained it is concluded that both the kinetics and the mechanism of T in a super-cooled gamma phase of the' alloys investigated may be interpreted by means of the usual theory of decomposition and martensitic transformation.

V substantially affects the critical points of alloys of the Fe-Co system, by lowering the temperature of the oZ -'-C- t transformation. The microstructure of slowly cooled alloys exhibits a characteristic grain lattice, probably due to the phenomenon of orderly regulation of grains. The hardness of cold rolled specimens is considerably increased by heating to 400-6000; any further increase in temperature reduces the hard- ness due to incipient - ' r ecrys tall iza tion.
