M. RyVkin (196,11). The samples (whose temperature varied from 90 to 5200K) were parallelpipeds of p silicon of dimen- sion n-10xlOxlS I ive contacts were formed by vacuum brazin VU a vapor depo- ;afg sited ~ aluminuM,Fatrie4. TAn equilibrium generation volume of carr ors was obtained by passing light t: i;ugh a' I cm thick silicon filter at room temperature. Under this method of measurement, the surface is found to have a negligible effect on the volume lifetime of cirriers. Since the concentration of.recombination conters in the samples was found to be slight, the relaxation time constant of photoconductivity -1 is the same as the lifetline Tn of electrons. The data for the dependence of -t,, on temperature and 1/2 L ACC NR: AP6015501 C;2- injection level y at high temperatures indicate that recombination accurs through mul- ticharged centers. The temperature dependence of the time constant in a p-type semi- conductor (in the case of doubly charged centers calculated using an activation energy of 0.41 ev) agrees with the results for the majority of samples. Furthermore, using the results of J. Okada (J. Phya. Soo, Japan, 14, 11509 1959) for thedependence of -r on y, the data indicate that the recombination level is in the lower half of the for- bidden zone and has a donor character in agreement with known data (m recombination levels in silicon. Finally, the activation energy E -8 , the concentration o and the 0 a capture cross section of carriers one and a . for cohesion levels iii determined from P the temperature dependence of the lifetime in a region of cohesion Irf a method devised by S. M. Rivkin, et al (PlT 2, 1966, 1960). The average values for the samples were R -E = 0.6 ev, a = (1-3-101 cm-3 a . 10-16 CM2, one it 10-11 cm2.

Izvestiya. Seriya fizicheskaya, v. 30, no.12, L966, 1954-1956 TOPIC TAGS; germanium single crystal, field emission microscopep adsorption, oxygen, oxidation, crystal surface, surface migration ABSTRACT: This paper reports a continuation of earlier work of the author (Radio- tekhnika'i elektronika, 10, 576 (1965)) on the purification of the surface of german field emitters. The apparatus and experimental technique are described in the earlier paper. The germanium emitter was etched in 5HN03:2HE:4C11.3COO11 as described by F.G.Allen (J. Phys. Chem. Solids, 19, 87, (1961)). The system was pumped down to 10-9 mm 11g and the germanium point was purified by the technique of E.C. Cooper and E.W.Muller (Rev. Scient. Instrum., 29, 309 (1958)), Oxygen was provided by a silver copper wire which had been oxidized in liquid air and mounted it, a side tube. The tip of the germanium point was cut on the [110] direction. Simeral field emission Card 1/2 ACC NR: AP 7001725 micrographs are presented and discussed. The migration rate of -~xidas on the clean rface was found to be enhanced by an inverse field and flashing at 100 germanium su to 1500 C. Heating to 3500 C drastically reduced the oxide migration rates and heating to 6730 stabilized the oxide films, which could not subsequently be removed even by heating nearly to the melting point with application of a field, Introductioi of oxygen at 4 x 10-8 mm Hg led to rapid covering of the germanium point by oxygen and decrease in the brightness of the image except at certain locations marking clusters of oxides. Adsorption of oxygen took place as rapidly at liquid air temper- ature as at room temperature. A lattice detect, marked by a chg.in of oxides on (113), (011), .(1110), and (131) faces, was noted on one of the g(irmanium points.Before the point wa*s cleaned the defect was marked by a dark band on the field emission image, indicating enhanced etching; selective oxidation on the defect took place after removal of about 100 atomic layers in the desorption field and flashing at 400-4500C.

The B. pes- tis E. V. 76 usually used for the production of vaccine was grown on culture media containing radioactive phosphorus (P32) of varying activity, from 0.6 ac. /ml. to 20 pc. /ml. From the medium containing 2.5 mc. /ml. a mutation of D. pestis was obtained different from the original strain in morphology, biochemical character- istics and metabolic rate. This new achromogenic strain of B. pvstis E. V. 76 is constant, its newly acquired features remaining unchanged after 15 months of culture and passage through experimental Wmals. Its antigenic structure Is ana- logous to that of the original strain. The stability of the changes thus induced is also shown by the absence of any regression of these changes after culture on selective media. References 17.

Upon the suggest-fon of Topaller, M. I., addition and removal of slag was done before complete melting of the bath, reducing Phosphorus content by 0-005-0-015%. For tile decrease of sulfur content new slag was added (freshly calcined lime 8-10 kg/ton, and crushed chamotte 2-2-5 kg/ton). After 15-20 min slag was completely removed and new deox1dizing slag was applied (limestone, sand, and chamotte in the amount Of 2% of metallic part of charge in ratio 1.2;1:1). At the same time, ferromanganese was added in order to obtain 0.115-0.20% manganese content in steel.

This is most conveniently achieved by the application of high-frequency induction or electrical resistance heating and the object of the investigation described in the present paper was to study the charact.,pristic features of -the recrystallization process taking plLaae under these conditions as well as the effect of various factors (annealing temperature, heating and cooling rates) on the Cardl/4 properties of so annealed titanium. The experiments were 411" 80982 S/180/60/000/03/oi4/030 Recrystallization of Technical Titan!umF-bRMnEj8Aap�d Heating by Passage of Electric Current carried out on specimens measuring 2 x 8 x 150 mm, cold-rolled to 60% reduction in thickness after a preliminary vacuum annealing at 780 0C. An alternating current (2 500 cps) was used for heating, the rate of heatin9 achieved in this way varying between 20 and 1 000 C/sec. The temperature and time intervals of the primary recrystallization irere determined by hardness measurements and the beginning and the end of recrystal- lization were pin-pointed by metallographic examination. The jesults were compared with those obtained on identical z-pecimens vacuum-annealed for half-an-hour at various temperatures. It was found that when electrical resistance heating was employed, the recrystallization range was displaced towards higher temperatures; thus, for instance, I-dien the rate of heating of 100 ()%;/sec was employed, the temperatures of' the beginning ahd end of recrystal- 0 lizatlon (tn and t k) were, respectively. 140 and 100 Card2/4 higher than in the case of the furnace (vacuum) annealed 80982 Recry-stallization of Technical Passage of Electric Current s/18o/60/000/03/014/030 E19~4E.j Titanium r R'j Rapid Heating by material. With increasing rate of heating v this difference increased, as is shown in Figure 2, where tn and t k are plotted against v (0C/gec). The rate of heating had no effect on hardness (Brinell) of 2 recrystallized titanium, which never exceeded 180 kg/mm The reduction in time, necessary for the process of recrystallization to proceed to completion, observed in specimens heated by the passage of electric current, 'was attributed to the fact that under the conditions of rapid heating, the processes of recovery and recrystallization took place both at the same time and temperature. J~~- ~ frequency induction heatingtiwas used in the last series of experiments, in which titanium strips (2 x 10 x 150 mm) were annealed by passing them at a constant rate through a loop inductor so as to attain the temperatures of 800-825 or 85o-88o Oc in 10 or 3.5 see, respectively. The mechanical properties and the degree of oxidation of Card3/4 specimens annealed by this method wore compared with those of similar specimens- annealed in the furnace (10 min at IK 809132 S/l8o/6o/ooo/o3/ol4/030 Recrystallization of Technical Titanium'haMFn-j'Rapid Heating by Passage of Electric Current 700 OC followed by cooling in air). It was found that the UTS of titanium was the same, irrespective of the method of annealing but the ductility of metal, annealed by rapid heating, was -31ightly higher and Ats grnin size was approximately 1.5 times smallon, in spite of higher temperature attained, the cbgree of oxidation of the rapidly heated apecimens was several times cower than that of the furnace-annealed material. In addition to these advantages, the technique of rapid annealing by means of electrical heatUng opens wide possibilities of me(;hanization and automation of the process of annealing of cold-worked titanium.

Th-e process of recovery was studied on both technical and high-purity iron (99.67 and 99.99%, respectively). The experimental wire specimens, 0.6 and 1.5 mm in (liameter', preliminarily annealed in vacuum (3 hours at 8000C) were deformed plastically at room temperature to 80, 84, 94 and 98% reduction in area. The kinetics of recovery were studied by measurements of the thermo-emf of plastically- deformed against annealed material, which were taken immedintely after deformation and during subsequent isothermal treatment at various temperatures, The value of (I - e/e ). where e0 and e denote the specific thermo-emf (jiV/?C) Card 2/4W 33182 s/l8o/6l/ooo/oo6/ol6/o2o A study of the kinetics E193/E383 before aii(. isothermal annealing, respectively, was taken as the measure of the degree of recovery attained.

It was inferred from the results obtained that the activation energy for recovery is a function of several states of the crystal lattice, which vary not only with the degree of preliminary deformation but also with the degree of recovery attained~ The dependence of the activation energy on the degree of recovery can be attributed to the following factors: Card 6/4R0 33182 sli 8o/6 1/oo(?/, oWol 6/020 A study of the kinetics ....

TITLE: A study of the grain growth in highly pure m-iron PERIODICAL: Akademiya nauk SSSR. Doklady, v. 138, no. 2, 1961, 338-341 TEXT: The iron investigated contained the following impurities : 0.001 ~fb 0, 0.001 % C, 0.002 % S, less than 0.002 % N and traces of Cu, Ni, and Si. Iron rods of 7.7 mm diameter were subjected to a preliminary treatment during which they were cold formed and, subsequently, subjected to a recrystallization annealing; the resulting grain size diameter was less than 0.2 mm. Grain growth was studied at electric heating and a mean rate of 200 degrees/sec. In the range of from 700 to 9000C, the rate of heating was reduced from 300 to 150 degrees/sec. After heating to a pre-determined temperature, the specimens were chilled in water, the interval between the end of heating and dipping of the sample into water being less than 0.02 seconds. The temperature conditions of heating were registered with a Cr-Al thermocouple, which was fixed in the middle of the sample, by means of a loop oscilloscope and a ballistic galvanometer. The results of Card 1/5 23832 S/020/61/136/002/015/024 A study of the grain growth in highly- B104/B207 measurement are graphically represented in Fig. 1. When heating at constant rate a, the rate of shifting of the grain boundaries G can be determined from the equation G - 2-adD/dt, where D = f(t) is the mean grain 2 diameter. If a is not constant, D =,y(T) must always be determined (T denotes the time). The lower part of Fig. 1 shows the temperature t as a function of time. The curve t = Q(T) is determined from the oscillograms. The curve D = V(,T) is constructed, as shown in Fig. 1, by means of the experimentally determined curve D = f(t). (Fig. 16). According to the above equation, the values G = 128; 188; 210; 230; 300 and 354010- 50M/sec are graphically obtained from this curve at temperatures of 735, 765, 790, 810, 865 and 8900C. In another experimental series, the specimens with 700 degrees/sec were heated to 610 t5oC and kept at this temperature for a varying length of time according to the individual specimen, e.g. for 0, 0-4, 1.0, 2.25, 3.0, 125, 275, 660, 900 and 1800 seconds. The respective ,arain diameters were: 43, 63, 87, 128, 141, 175, 194, 205, 210 and 240-10-4 CM.

The slowing down of the shifting rates of the grain boundaries is explained by the reduction of the radius of 3urvature of the grains and the increasing concentration of impurities at tae grains. Owing to the high purity of iron, this state occurs only with very large grains. Prom the discussion of the results the authors conclude that the mechanism for the grain growth as suggested by Mott (Proc. Phys. Soc., 60, 391, (1948)) is very probable. Accordingly, the grain, when growing, melts at its boundaries and solidifies again with the boundary being shifted in outward direction, The authors, experimental data can be easily described by Feltham's equation (J. Inst. Metals, 85, (2) 95, (1957); Acts. metallurg., 5, 97 (1957); Proc. Phys.

B104/B207 The results of the second experimental series are in good agreement with (2). Herefrom, 25.3 koal/gram-atom is obtained as activation energy for the grain growth. In a preliminary study (Ref. 20 Izv. AN SSSR, Metallurgiya i toplivo, No. 2, (1960)), basing on the hypothesis on the activatiQn energy of various processes in solids, the authors obtained theoretically an activation energy of 22.2 kcal/gram-atom. Finally, the fact is discussed that in the case 'of lead and iron AH and q are almost equally high (s e'e Ref. 20). This is brought into relation ivith the melting and re-solidification of the grain boundaries. V. P. Fedotov supplied the pure iron for this study.

In -the present investigation the effect of the rate of heating, during aniiealing of cold-worked commercial grade Ti, on the kinetics of recrystallization, the grain size of the recrystallized materie1l-------'_ and the critical degree of deformation, was studied. The experiments were carried out on 1.5 x 6 x 150 mm test pieces which, after the last intermediate annealing, had been plastically deformed to 9.8, 21, 40 and 60% reduction.

Hardness of the central part of the test piece 'was measured, the grain size determined and, when necessary, X-ray diffractioa analysis carried out. With isothermal annealing in which the effect of the degree of preliminary deformation, c, and the rate of heating on To and Tj was studied (where 'ro and denote, respectively, annealing times required to start and com~plete the recrystallization process), it was found that with increasing E both To and Tj decreased at a gradually diminishing rate, becoming negligible at E -.;,40%. Increasing the rate at which the test pieces were brought up to the annealing temperature also caused a decrease in both T 2 and Tl for all values of E, typical results obtained at 900 C being as follows. For specimens deformed to 9.8% reduction and heated at a rate of 30 and 300 *C/sec, To was 15 and 8 sec respectively, the corresponding values of Tj being 70 and 50 SOO;* for specimens deformed to 40% reduction To was 3 see at 30 'C/sec and 0.6 sec at 300 *C/sec, the corresponding valuesi of Tj being 5 and 2 see. In the non-isothermal annealing, each test Card 2/,f The effect of the degree of 5/180/62/000/003/Oo6/oi6 E193/E192 piece was heated through a range of temperatures to determine the effect of various factors on the temperature of the beginning and end of recrystallization of T! (tH and tK, respectively) and it was found that, irrespective of the degree of preliminary deformation, both the beginning (tH) and the end (t:.K) of Ti recrystallization increased by 70-150 *C on accelerating the heating rate, the rate'of increase in each case diminishing as the heating rate increased. At any given heating rate both tH and tK increased with increasing C; the rate of this increase also became insignificant at C > 400/o. Typical results tire reproduced in Fig,3, where tH and ty, (*C) are plotted against C (%), graphs a and relating, respectively, to specimens heated at a rate of 30 and 300 OC/sec.

The results of the final series of experiments showed that the detrimental effect of preliminary deformation on the grain size of recrystallized Ti can be considerably reduced by increasing the rate of heating, thus obtaininj finely-crystalline and more uniform structure.
