The following four procedures were employed in the C of the speci- mens: 1) C temperature: 9200 ; carburizing agent (CA): kerosene; a carburized layer (CL) 1.6-1.9 mm deep was obtained after a period of 20-24 hours; 2) C temperature: 9200; CA: spindle oil Nr 3; a CL 1.6-1.9 mm deep was obtained after 18-20 hours; 3) C temperature: 10000, CA: kerosene; a CL 1.6-1.9 mm deep was obtained after 13-16 hours; 4) C temperature: 10000; CA: spindle oil Nr 3. After C a portion of the specimens was subjected to normalizing followed by tempering and stress annealing. By means of mechanical testing and metallographic Car 1/2 studies it was established that increasing the C temperature to 137-58-3-5520 High Temperature Carburization in Shaft Furnaces 10000 doe-s not produce any large incl-Ca5CS in grain growth in steels 18KhGT and IZKhNZA; in the case of ZOKh steel prain growth was observed at 10000; it is, therefore, necessary to normalize this steel prior to tempering. At a temperature of 10000 the C time required to obtain a CL of specified depth is reduced by 20 to 30 peTcent. C at 10000 raises erb and ak values sometimes and increases the resistance of the steel to static bending. A. B. Card 2/2 ZOBOVAP Z.T..

The first one was characterized by an increase in temperature !in the zone of welding caused by -the dry friction between contact surfaces, removal lof oxide filmsp formation of cohesive compounds, and a low resistance to fracture. iThis stage lasted for 0.1-0.3 sec. The process responsible for increasing the Iresistanoe occurred in the second stage. The first group of materials chosen for this study conelated of Cu + All Al + All and Cu + Al; the second group consisted of 'Ti + Cu and Ti + Tie The welding was performed in a UZSM-1 machine equipped with a- power generator MS-50I* In the first group (under the influence of ultrasonic oscillations) the surface flow of the sa9*1 led to the breaking down of blooks of Card 1/2 'ACCESSION NRI AP4034062 ,coherent scattering. The intensities of the lines (111) of Cu and Al were reduced :significantly. The splitting of line (111) of Cu in the zone of,plastic flow of the :compound Cu + Al indicated the existence of a solid solution of Al in Cu along with 1pure Cu. In the cohesion zone only the solid solution wao.observed. The appearance :of Cu&1 accounted for the aging process. In the second group the breaking down of scattering blocks was also observed. In the zone of plastic flow a solid coheren ,solution of Ti in Cu was noted in place of Cu* The aging process was caused by the' !appearance of the Ti Cu phase.

It was assumed with the dissociation of phanyl-diaconium-boron fluoride that the entering of phenyl into the meta-position with respect to the meta-11orientates" proves the cationic nature of phenyl. With the decomposition of this compound, the products of the entering of phenyl into the benzene-ring of the methyl- and ethyl-ester of benzenesulphoacid could not be obtained. The action of phenyl was directed to the sulphalk-oxyl-6-roup. Phe- nylester of benzenesulphoacid proved to be the sole determinable reaction-product in both cases. The yield amounted to 4o% in Card 1/2 the case of ethyleatert to 35% in the case of methylester (of Decomposition. of Phenyldiazonium-Boron Fluoride in 62-58-5-6/27 the Ester of Benzenesulpho-Acids and in Acetophenone benzenesulphoacid). This phenyl thus acted exclusively on the sulphalkoxylgroup. A mixture of the m-ard p-phenylacetophenones (relation 4:1) is formed in acetophenone with the decomposition of boron-fluoride of phenyldiazonium. These reactions prove the heterolytic character of the decay of phenyldiazonium-boron fluoride. There are 11 references, 3 of which are Soviet.

TITLE: Decomposition of Aryl-Diazonium Boron Fluorides in Nitrobenzene (Razlozheniye boroftoridov arildiazoniyev v nitrobenzole) PERIODICAL: Izvestiya Akademijk nauk SSMI Otdoleniye khimicheskikh nauk, 1 1958, Nr 12, pp 1452-1460 (USSR) ABSTRACT: In the present paper the authors investigated the decomposition of aryl-diazonium, boron fluorides in nitro-benzene with aryl= r,kenylv paratolyiq parachloro phenyl, paramethoxy phenyl, orthocarbomethoxy phenyl, paracarbethoxy phenyl, orthonitro phenyl, and orthochloro phenyl. Besides a direct precipitation of reaction products by means of distillation and crystal- lization, the relation between the substitution products of the benzene nucleus - ortho-, meta- and para-isomers - possibly forming in the reaction mixture, were determined by optical annlynis. In the first i3ix cases the aryl formed in the de- comp;sition of,aryl diazonium boron fluorides in nitro-benzene entered the nitro-benzene nucleus only in a meta-pCBitiOrl to the nitrc group. Of the 3 possible isomers (ortho-, penta-, Card 1/3 para-) only one, the corresponding metanitro-biaryl, was SOV/62-58-12-8/22 .Decomposition of Aryl-Diazonium Boron Fluorides in Nitrobenzene separated. The optical analysis of these mixtures by ultra- violet spectroscopy likeivise proves the presence of meta- "Laomers only. Absorption curves of the investigated substances were obtained by the spectrophotometer SF-4, a censtruction by V. I. Dianov-Klokov. '?he authors thank 1. V. Obreimov and 1. Xachkurov-a for thoir optical measurements. The entrance of aryl from the aryi-diazonium, boron fluorides into the nitro- benzene in the meta-position proves the electrophil-~c, cat- ionic, nature of this ary'. and EL heterolytic character of the decompoaition of the diazonium salt. Only in the last two cases the a:7y! unexpectedly entered the ortho-position of nitro-benzene. Only 2 diphenyl derivatives were separated: 2,2-dinitro-diphenyl and 2-chloro-21 nitrodiphenyl. In the first case a possible crosswise conjugation of the two nitro groups with both benzene nucle-i and besides that a coplanarity of two benzene nuclei in such a substituted diphenyl may be regarded as the cause of that formation. In the second case there is also a possible con3ugation of chlorine atom electrons with the electron system of 2-nitro-diphenyl and a coplanarity of such a molecule. In this case also the possible presence of Card 2/3 a certain ortho-effect must be considered. It is expressed by SOV/62-58-12-8/22 Decomposition of Aryl-Diazonium Boron Fluorides in Nitrobenzene the interaction of the electron cloud of the chlorine atom with the positive charge of the nitrogen atom of the nitro group.

During the decomposition of 4-methylphenyl- and 4-chlorophenyldiazonium boron fluorides, the aryls enter all of the three positions of nitrobenzene,the orthoisamr being formed first of all. The following compounds were iso- lated: 4-methoxy-41-nitrodiphenyl and 4-methoxy-31-nitrodiphenyl. The presence of 4-methoxy-20-nitrodiphenyl, 21-nitro-, 41-nitro-, and 31-nitrochlorodiphenyls was spectrographically proved.

Vol 2. Moscow, AN SSSR, 1957, pp 52-56 ABSTRACT: The heat of' subli.mation (HS) was determined by the rate of evaporation. Two specimens of alloy of the same chemical composition are mcounted in. a ceramic cup, one facing the other at a dista ce of I mm. The cup is placed in a vacuum furnace ( - 10- mrn Hg), One of the specimens contains a radioactive isotope of the constituent investigated. The specimens arc! heated to a specified temperature and held at this temperature for a specified time. The vapor pressure of the components of the alloy corresponding to the tempera- ture of the experiment is established in the space between the specimens. A reaction of isotope exchange goes on between Card 1/2 the samples, the rZLte of which is gaged by the growth of SOV/1 37--58-7 -15610 Determinatioh of the Heat of Solid-state Sublimation of Iron (cont. J) radioactivity in the specimen which had been originally inactive. To bring the reverse current to a minimum, the area of the nonrarioactive specimen is made 20-30 times as large as tbe surface of the active specimen. The HS of iron in a number of Fe-Cr alloys (0. 8-87. 50/o Cr) was investigated in the 1100-IZ500C range. The relationship of the HS to the corTcp osition has the appearance of a curve with d maximum in the region of. 50 ~o Cr. At 0. 8% 50%, and 87 '576 Cr the AHJPe is 98, 161, and 99. 3 kcal/g. atom, respec- tively. The calculation of the variation in thermodynamic activity of the Fe in relation to the Cr content in the alloy shows that 'in the region of inter - mediate concentrations of Cr there exists a considerable negative deviation from the ideal. This indicates that in this region the interaction between like atoms is weaker than between unlike ones. This situation leads to the formation ,of-;:. cL phase on lowering of the temperature. Data on the heat-resistance of Fe-Gr alloys likewise indiicate that the highest resistance is possessed by alloys containing -6007o Cr. 1. Chroni:lum-iron alloys-Properties 2- iron--Sublimat-ion 3.

A method and instrument (1) based on the principle of isotope exchange for the purpose of investigation of the vapor pressure and the diffusion constants of metals are described. The Fe59 isotope is employed for study of industrial Fe and also of Fe ir. a number of its binary alloys. The isotope is introduced into the alloy by metallurgical methods.

In order to remove all gas from the metal, the extra specimen was first fused in vacuum. Industrial Fe was investigated in the 1120-12550 temperature interval. After a number of anneals of varying dura- ,jr,ific activity of the S was measured, and the amount of Fe con- tion, the spF densing o!-The target was counted. Under conditions of unilateral exchafige, L e. , under experimental conditions in which the area of the radioactive S is set at only 1/20 to 1/30 of the area of a non-radioactive specimen so as to re- duce to a minimum the feedback of vaporized atoms, the solution of the prob- lem of rj~ass transfer for the concentration of isotope is analogous to the solution of the problem of heat transfer from a semi-infinite heat source in a medium the temperature of which remains zero. A method of calculation on the basis of the data of the kinetics of isotope exchange is presented, cover;.ng rate of evaporation, vapor pressure, and the coefficient of self-diffusion of industrial Fe. The data obtained were employed to derive the heat of sublima- tion of Fe, AH=97 kcal/&-atom, and the energy of activation of self-diffusion, Q=70 kcal/g-atom, which is completely in agreement with the literature data. A diagram and description of an 1, making it possible to heat a number of pairs of disk-shaped S simultaneously, are presented.

All the tests were carried out in vacuum with a residual pressure of 10-5 mm Hg, both for constant temperature and also for cyclically varying temperatures. In the latter case the specimen was tested with a constant torque at various temperatures. Straight line dependence on the diagram strain versus time was taken as evidence that the steady state of creep had been reached at the given temperature. The reliability of the obtained results was verified by the coincidence of the activation energy of the steady state creep during gradual increase and decrease in the temperature. In the case of titanium, metal of 99.5% purity was chosen that had been forged into rods of Card 1/4 86965 S/180/60/000/005/006/033 E073/E535 Investigation of Plastic Deformation ofHigh Melting Alloys at Elevated Temperatures 12 mm diameter and also iodide titanium that had been purified by zonal melting. The sDecimens had a gauge length of 12 mm and a diameter of 3 mm. Their surface was carefully polished, The creep was tested in the range of 0 modification (1000 to 1500 C) with torques of 90.5, 109, 137 and 200 g/cm.

The dependence of the logarithm of the speed of creep of Or on the reciprocal of the temperature for various stresses is graphed in Fig-3. Simi]Lar results for niobium specimens are plotted in Fig.5. The dependence of the activation energy of chromium and niobium on the applied stresses is plotted in Figs. 4 and 6. The following conclusions are arrived at: no temperature dependence of the activation energy of steady state creep was observed for chromium, niobium and V)( titanium. With increasing applied stress, the creep activation energy of Cr and Nb decreases, whilst that of Ti remains unchanged. The absolute value of the creep activation energy of titanium is less than that of self-diffusion. The creep activation energy of Or and Nb at r = 0 is a complex value equalling in the first approximation the sum of the activation energy of self-diffusion and the energy of formation of vacancies.

Dekhtyar et al. (Ref.1) and other authors (Refs 2, 3) have previously shown that plastic deformation affects many properties. The present work gives preliminary results of an investigation of the influence of plastic deformation (torsion) on the rate of evaporation of iron from type 10 steel (0.10% C; 0.45 Si; 0.03 P; 0.02 S; 0.26 Al; remainder Fe), The apparatus developed and used is shown in Fig.1; the hollow cylindrical specimen has its open end closed with a tantalum diaphragm to form a Knudsen cell. The specimen, subjected to torsion if required, is heated in a Card 112 S/180/60/000/005/021/033 E111/E135 Influence of Plastic Deformation on the Kinetics of Evaporation of Iron from Type '10 Steel graphite inductor of an axially varying wall thickness. After fabrication specinens were annealed in helium for 30 minutes at 1200 OC,, sealed in;quartz capsules and irradiated with thermal neutrons, giving Fe59. The rate of evaporation was found from the activity of the deposit on a molybdenum foil (polished to a mirror finish) in an aluminium holder cooled with liquid nitrogen. Fig.2 shows evaporation xates of iron for undeformed specimens of the steel (curve 1.) and pure iron (curve 2).

Analysis of the structure of the source showed that it was obstructed because the distance between the internal loop', was almost 3 times greater than that of the external loops. As a result of accumulation of groups of dislocations, the stress concentration in individual-places may increase considerably and lead to the formation of microcracks and subsequent brittle fracture. For chromium this obstruction of -dislocations can occur even at high temperatures leading to brittle fracture. This explains why chromium has an intercrystalline fracture up to 0.75 Tfusion- An a result of the action of the Frank-Reed source, a large number of dislocations are formed and slip lines appear.

A solution consisting of 95% phosphoric acid and Vc water (Ref. 1) is used as electrolyte. Work is conducted with an anodic current density of 1.8 a/CM2 and a terminal voltage of 7 v, a layer of 1.5 mui thickness being separated from the crude sample in the course of 2 hr. Castings of electrolytic chromium, obtained by floating melting in pure, dry helium atmosphere, of the following dimensions were used as crude samples: length of the tapered part 15 mm, diameter3-mm, length of the crown pieces, (at both ends) 5 mm, their diameter 6 mm. These crude samples are hung into the electrolytic bath, and current is fed through by means of molybdenum wire contacts. The Card 1/2 S/03 61/027/002/ClO/026 Electrolytic method for the ...

Furthermore, such data as have been reported in technical literature are often very contradictory. For these reasons a re-examination was made of self-diffusion of chromium on specimens prepared from electrolytic chromium (99.96s'a pure) with nitrogen content of less than 0.010% and oxygen content of the order of 0.1%. The spepimens were prepared by levitation melting and casting in copper moulds in an atmosphere of dry and purified helium. The specimens'were in Card l/ 4 On the self-diffusion of chromium s/iSo/62/000/002/009/018 E040/E135 the form of rings 16 mm in diameter. After polishing, Cr5l was deposited on the specimen surface under a vacuum of 1o-5 mm iig. Care was taken to ensure art even thickness of the deposit of the radioactive chromium. Diffusion annealing was carried out at 1050-1400 OC in a sPecial vacuum furnace in a corundum crucible, using simultaneously two specimens pouitioned face-to-face; the actual annealipffig temperature being contz-ollecl by n2eans of two Pt/Pt-Rh thermocouples.

The temperature dependence of chromium self-diffusion was found to obey the following relation: 1) o.o647 exp 59200~ (1) IRY-- ) where R - universal gas constant and T - temperature. Investigation of the self-diffusion of chromium is also of great interest because chromium has a body-centred crystal lattice structure.

The tests were performed with pure electrolytic chromium (99.967.). Chromium samples 55 mm long and 6 mm in diameter were cast in pure helium and were then tested for creep on the 724-4K machine under constant torque at temperature.; up to 1500-1600C. It was found that one of the most important factors at high temperatures is the position of the boundaries and the presence of processes Card -1/2 ACCESSION NR: AT4013922 arising at the boundaries. Photomicrographs in the article show the gradual development of defects at the grain boundaries in2the process of buckling of the chromium sample at 1200C and a load of 2.05 kgjmm . Another part of the experi- ment involved tests on molybdenum. It vae found that molybdenum failure at the grain boundaries started at a,significantly lower degree of deformation, which showed that molybdenum has a higher resistance to plastic deformation and a relatively lower plasticity in comparison to chromium. Thus, when creating heat-resistant alloys, not only should the solid solution be strengthened, but the possibility of strengthening the grain boundaries should be considered.

Metally, no. 4, 1966, 99-102 TOPIC TAGS: chromium, polycrystal, metal heat treatment, cyclic heat treatment, crack propagation ABSTRACT: The authors study the effect of cyclic heat treatment on the process of crack formation in polycrystalline chr4mitmi. Test specimens 5 mm in diameter and 10 mm long were made from 99.96% purele Ilectrolytic chromium. In each heat treatment cycle the specimens were .*aeated to 12001C vith holding for 5 min anq subsequent rapid cooling in water to room 'temperature. No special measures were ta4n to protect the specimens from oxidation. After each 10 cycles the microstructurelof the metal was studied and the microbardness was measured with a load of 50 9 on the indenter. A slight change in microhar(Iness from 210 to 250 kg/mm was observed after 100 cycles due to the hardening action of cyclic thermal stresses and diffusion of oxygen from the surface to the inner regions of the specimen. Cracks appear after 4o-60 cycles preceded by dislocation pile-up in certain slip planes, The increase in dislocation 1/2 UDC: 539-4-011 0 density in these planes results in the formation of submicroscopic cracks which then propagate at an extremely high rate of speed due to the increased brittleness of the material. The possibility for development of slipping in the secondary slip system or development of other processes, e. g. transverse slipping, results in relaxation of the stress in front of the developing crack and propagation of the crack in the parallel plane creating fwrorable conditions for "relay-race" crack propagation.
