Doklady, v. 140, no. 6, lo61, 1301 - 1303 TEXT: By x-ray diffraction studies, microscopic examinations, and hard- ness measurements (Vickers hardness, 10 kg load) the authors constructed a complete recrystallization diagram.of cast tungsten (99.6 %). After casting the specimens were compressed (70 %) and annealed (16000C). The material had a grain size of 40 - 50 A. The specimens were compressed from 6 to 90 % with'a hammer in a hydrogen atmosphere at 700 - 11000C. These temperatures are just below the recrystallization temperature of tungsten. After this treatment specimens of each deformation degree were annealed in the range from 1000 to 25000C at every 1000C for one hour (between 1400 and 16000C at every 5000. The specimens were electro- lytically polished (10 % NaOH in water, 1.7 a/cm2). The recrystallization Card 1 2981 3/020/61~140/0006/014/030 Recrystallization diagram of cast ... B104/B102 diagram of deformed tungsten is shown in Pig. 1. At deformations between 30 and 90 %, recrystallization sets in at 14500C. The recrystallization takes place between 1450 and 16000C. At a temperature of 17000C, the grains start growing. At 9 % deformation, recrystallization sets in at 16000C. The critical degree of deformation shifts from 12 % deformation at an annealing temperature of 16000C to 6 % deformation at an annealing temperature of 21000C. The coarsest grains were obtained by annealing at 25000C. With an increase of the degree of deformation from 30 to 90 % hardness increased from 380 kg/mm 2 to 440 kg/mm2. When recrystallized grains appear, hardness drops to 360 k9/mM2. The optimum annealing tem- perature of tungsten deformed bY 50 _ gea was assumed to be between 1500 and 16000C. A comparison with data on high-purity single crystals showed the strong influence of impurities on the recrystallization temperature. There are 1 figure and 4 references: 2 Soviet and 2 non-Soviet.

E193/r,333 lound to be directly related to the broadening of grain boundaries. This was taken to indicate that the brittleness of recrystallized tungsten and other similar metals was caused by inter.-ranular internal adsorption of impurities. In view of the results obtained it urould appear that there are four possible ways of tainimizing the embrittlinG action of recrystallization of tungsten and other Metals prone to this effect: a) reducing the impurity content of the metal; b)'L grain refinement; c) heat-treatment: d) alloying with elements inhibiting intcrgx:anular internal adsorption and harmful L.iptiz-itics. That the last of those methods may be no less e*Cfectivo than the first is indicated by the results of many invest, i Sat ions carried out by V.I. Arkharov and his co-workers and by the fact that the plasticity of W and Mo can be increased considerably by the addition of 20 - 35") rhenium in the former and 40 - 505 r4enium in the latter case.

In the 1200-2300C range, both tantalum and its !alloy have a single-phase structure. The recrystallization tempera- 'Card l/ L 1~778_65 ACCESSION NR: AP4046091 tures of are-cast tantalum And tantalum alloy were found to be 1200-1300C and 1500C, respectively, and thope of electron-beam-melted tantalum and tantalum alloy (hi;theryurit )t,) IOOG-1100C and 1300C, respectively. These results indicate that the recrystallization tem-,' perature depends to a great extent on the impurity content. During the recrystallization of tantalum and its alloys, and of other re- fractory metals, intererystalline adsorption of impurities occurs. The minimum content of Impurities within the grains is observed with an,lealing at temperatures exceeding the recrystallization temperature of the metal by 100-200C. A further increase in temperature leads to a reversed migration of impurities into the grains. The increase In hardness, and the accompanying decrease in ductility and increase, in the tantalum lattice parameter after annealing. at 1800C, are ex- plained-by the reverse migration of impurities and the contamination occurring during beat -treatment. The fact that different refractory metals show different behavior during recrystallization can be ex- plained by the different-9,61ubilities on interstitial elements in those metals.

Annealing in air at 500C for 5 or 10 hr followed by homogenizing annealing at 1200C in a vacuum, increased the oxygen content to o.4 or 0.7% respectively, which was below the limit of oxygen solubility of tantalum at 20C. The sheets were then cold rolled with a reduction of 50% and vacuum annealed at 800 to 2000C for 1 hr. The recrystallization temperature of oxygen-poor and oxygen-rich tantalum as determined by x-ray diffraction pattern examination and by hardness measurements was 1200C regardless of the oxygen content. Annealing at tempersbzes!' above 1200C and below 1600C brought about no noticeable changes in hardness. However annealing at 1800C lowered the hardness in direct proportion to the initial oxygen Card 1/2 UDC: bb9.2~14!>40.>J - - ------- - ACC NR, AP60320619' content to roughly the same value. Thus, after annealing at 1800C, the oxygen-rich and oxygen-poor tantalum have the same microhardness and also the same lattice par- ameters. This appears to indicate that the embrittlement of recrystallized tantalum molybdenum, tungsten and chromium is brought about not by interstibial, but by sub- stitutional elements.

Special studies of driver reactions show a correlation between attentiveness during training and reliability as a driver. Tests of drivers' ability to quickly orient themselves over Gtrange terrain revealed that over half (17 of 24) could not do co successfully. Special experiments showed that in 68% of the cases, drivers capable of rapid thinking were more effective drivers because of their fast reaction times, but ovor-roaction in dangerous in drivers.

ABSTRACT: An attempt is made by the authors to give a brief summary of the most important Soviet works and achievements in this field. The first electron tubes were produced in the Soviet Union in 1918 by M.A. Bonch-Bruyevich, who initiated a small- scale production of receiving tubes. The first investigati-ons of the cathodes were carried out by several workers a few years later. In 1920, P.I. Lukinskiy and N.D. Semenov cerried out first investigations of the photo effect. At the beginning of the Thirties, the work on cathode electronics was primarily carried out in a laboratory in Lenj.n(~,rad attached to the factory "Svetlana" and in a laboratory in Moscow. The Moscow laboratory was directed by P.V. Timofeyev and it was primarily interested in the investigation of the photo effect and the secondary emission. At about the same time, I.Ye.Tamm and S.P. Shubin proposed a theory of the photo effect which is valid up to the present day. The photo effect vas also investi- Uardl/3 gated quantitatively on Ag-Cs cathodes and on Sb-Cs cathodes. 40 Years of Soviet Cathode Electronics. log-11-8/8 In the field of secondary emission) the follo~,.ring problems were investigated: velocity distribution oT the secondary electrons, emission of alkali-haloid compounds, emission of thin, transparent films, emission of dielectrics, and Sb-Os cathodes. A new era in the development of the cathode elec- tronics dates from July, 1944, when a conference on the problem took place in Moscow. During the conference, a number of important papers were read by various workers in this field. A rapid development of the electronics began in 1951, when a conference devoted to cathode electronics took place in Kiev. During the conference, a large number of papers were read on the following problems: electron microscopy, pulse emission, cathode sptAttering, secondary emission, Sb-Cs cathodes, Pb-Cs cathodes and secondary ion-electron emission. Since that time, a large number of technical papers have been published in , which the following problems have been considered: determin- ation of the vapour pressure of barium, ireasurement?,of the semi-conductor layer of the oxide cathodes and their work functions, mono-layer cathode systems, investigation of the natural semi-conductors such as PbS and CdS, special investi- Uard2/3 gation of the physics of secondary electron emission, ion . .

Understanding of the mechanism of the operation of thermionic cathodes requires the knowledge of the value of the saturated barium vapour pressure in the presence of BaO and the activators. This work aimed at determining the pressure and its temperature dependence. The experiments were carried out on a liecial tube which is shown in Fig. 1. The tube consisted of: a container; 2)a heater; .3) a tungsten ribbon; 4) an electron gun, and 5) an Alp6rt-type ionisation vacuum gauge. The investigated reaction was taking place in the container,which consisted of two hollow cylinders. The con- tainer had an aperture of about 0.5 mm at its lower end. The stream of barium atoms ejected from the aperture of the con- tainer was collected by the tungsten ribbon.

A similar cuLrve for the barium vapour pressure of a system with sil-'Icon activator is given in Fig. 4, while Figs. 5 and 6 show the pressure for tantalum and titanium activators, respectivel~y. The results are additi- onally summarised in Table0lv p.1524. From the data obtained, it follows that, at 1 600 K. molybdenum has the lowest reducing properties and it is followed by silicon,otungeten and tantalum; at operating temperatures of about 1 300 K, the reducing properties are the lowest-in molybdenum and the highest in titanium.

The cathode of the valve is a tungsten wire 110 mm, long and 0.1 mm in diameter. Two such cathodes are availableg one of which is a spare. The grid of the valve is 30 mm in diameter and 50 mm long. it consists of a tungsten wire 0.4 mm in diameter. The grid is so constructed that it can be heated by an electrical current. The grid is isolated from the metallic supports by tubular ceramic insulators. The ceramic tubes can be heated up to 900 OC and can thus be reliably outgassed. The ion collector is a tungsten wire 50 mm long and 0.2 mm in diameter. The valve turned out to be more sensitive than the valve described by Card 1/2 Bayard and Alpert.
