Sbornik statoy.- Moscow, Metallurgizdat, 1963, 178-181 TOPIC TAGS: conductance measurement, solid metal conductance, liquid metal con- ductance, high temperature conductance, non-clectrodo conductance measurement., conductance measuring equipment J STIUCT: Using a new instrument, which is described in detail in tLe text, con IB solid or liquid metals can be measured over the range 20-2000C, honc; ductanco in even for Ti, V or Zr. The design is based on a non-electrode method of measuring conductance in terms of the moment ol forces acting on a specimen in a rotating 'hi and located inside ma.-aetic field. The instrument has stator coils 180 cm gh the bousin-, hence the entire assembly can be made of common structural stool. a The usual operation is in an. atmosphere of inert gas (4rgon), although tests can be carried out in 0,._,10-3 mm Ha vacuum. Dependence of the angle of twist on spgcimei~rheight for.a specimen aiameter of 14 mm was plotted in a diagram (see co ACC U-'SION NR: AT11013987 Fim. 1 in the Raclosure) which can be used to reduce all angles of twist to a Iuniform specimen height and to determine the conductance of a given material with the aid of a simple formula: WSJ- whore X is the instrument-constant determined from the angle of twist of a uniform,. hei-ht standard, i is the average current intensity in stator components in mean ampa."dniq,, is the angle-of twist reduced to uniform specimen hoight,:ih radians., Temperature was shown to have little affect on the value of K.

Chernaya metallurgiya, no. 5, 1964s 17-21 TOPIC TAGS: vanadium pentoxide, SiO sub 2, Cr sub 2 0 sub 3, Cu sub 2 0, termal change, semiconduction, chemical activity, ZrO, sub 2 crucible, ionization ABSTRACT: There is a'recent tendency of investigating the reduc- tion - oxidation of matals from the viowpoint of semiconductivo pro- perties* Thus, the authors observed the effects Of S102, Cr201 and Cuq0 on the character of thermal changes in the electrical"con- ductivity and chemical activity of vanadium pentoxide. Specimens were'prepared by mixing V 0 for 50 hrs. with a rated amount of additives and melting in irb crucibles. The specimens rre crushed and passed through a 120 mesA sieve. A load of 1.5 t/cm was applied to produce 4 X 5 X 40 Mm compacts which were sintered in an oxygen bard ACCESSION NR: AP4039271 stream at 600C for 7 hrs. Impurities exerted a considerable in- fluence on the character of changes of the electrical resistivity of specimens according to temperature. They affected the initial ~~l temperature at which the conductivity of vanadium pentoxide began predominating over the conductivity of-impuritio3. The higher the concentration of impurities, the greater the effect on the initial temperature at which the inflection on,the conductivity curve appears. Low reducibility S'O and Cr 0 act in one diro'ction while CU 2 0 acts in the opposite dire tion. ~N authors contend that low roKcibility oxides act as acceptors and high reducibility oxides ias donors. As S102 ~nd Cr203 concentrations are heightened, the -I temperature of transition of the conductivity of impurities to that. of V 0 increases. Impurities with a low-temperature ionization 2 were f9und to lower the temperature of initial oxide reduction and increase chemical activity. High-temperature ionization impurities 7act in the opposite direction. The authors believe that it may be- come possible to predict the character of'the effect of impuriti:es on the properties of oxide.

The Segden method of testing was used (maximum gas bubble 1i pressure in two capillaries of a different diameter). Specimens were prepared from "TO-00" Ti, spectrally pure Sn and Al, and iron' carbonyl. The surface tension of all Ti-Al-Fe alloys was measured -t.at~'1750C, and of Sn specimens at 1750, 1850, and 1970C. High- density graphite crucibles were used. ;Sn was found to lower Ti surface'tension more than Al and Fe,, Evidently, an increase in the , Frd ACCESSION NR: AP4039274 surface concentration,,.,of Sn,and Al which react weakly to C would lower pickup. The le4st carburization:was observed with a to 14% Al and 4% Sn cast in electrolytically produced white corundum mo ids with an ethylsilicate bond and coated with colloidal graphite; surface smoothness was good and all specimens were,readily removed i- without pickup. Experimental data coincided with calculations. Ti density was lowered by Al and heigh~enedby Sn gdditions at about., thQ same rate. 20% Sn increases the dqnqity of hot Ti,to 4e4 g/ cm4 while 20% Al decreases it to 3.89/qm;. The authors conclude ~that additions of Sn in excess of 8% and of Al in excess of,10% to cast Ti alloyshave a beneficial effect on the surface tension of-- Ti.

Chernaya metallurgiya, A TOPIO TAGS: titanium carbide, titanium tetrachloride, methane disso-i :ciation, vapor.pressuret hydrogen, titanium tetrachloride ABSTIUC.~: Although the method of precipitating titanium carbide Is, -well knovn, the mechanism of the formation of high-melting carbides remains to be studied. Por that purpose, the authors observed the process of titanium carbide precipitation from a mixture of titanium tetrachloride, methane and hydrogen. The process +-ck place-in'the gas flow (hydrogen, helium) at.atmosphorio pressure. The possibility-. of forming metallic titanium under conditions of a substantial excess' :,of hydrogen was Investigated b~ holding an.incadesoant titanium fila-;, a gas flow consisting of titanium tetrachloride and hydrogen all.tests the titanium filament was dissolved which Co- .'Card ;!ACCESSION NR: AP4022897' with available thermodynamic data. The authors attribute the! precipitation of titanium Carbide to the reaction of elementary do- ~composition of methane that occurs on the hot surface. This reaction. 'has been studied in great detail by many authors and the thermodynam-, ic as well as the kinetic constant are well known. Methane.was foundv 'to be thermically unstable dissociating at temperatures above 10000. Therefore, the processes of the formation of a carbide film on the carbon surface differ only In that the carbon Is provided by the diff- usion of the carbon base or as a result bf the decomposition of meth-, :ane by the gaseous phase., In the.latter case, the rate of titanium ,oarblde formation is affected by the partial pressure of methane in ,'the initial mixture. 'Theincrease in the'partial pressure was accompl!' ~ h n iihie by a IncreasA in the rate of titanium carbide formation. How-, !ever, above 1.4-10-4 atm. partial pressure either accelerates the :formation very little or not at all. Titanium tetrachloride *was not 'affected by the partial.pressure of methane. The authors account for :the precipitation of metal by the reducing effect of hydrogen on tita' ~nium tetrachloride.

The rate of formation of t solid pro- ~ph 5 0 ducts was determined by weighing the thread before and after the proces f deposi- b tion, at periodic intervals of time, and the composition of the coating was radio- graphically analyzed. on this basis, the following empirical equation was derived for the rate of Nb deposition as a function of the partial pressure of NbC1 5 in the vapor-gas phase 6-10'3 p0.7 1/3 UDC: 669.293 Card W.U 66 -ACC7(4k. _AP5028978 and for the rate of deposition -3 0.8 1.88-10 P where W is the rate of Nb deposition, g_atoM/cm2_O.5 hr and P is the partial pressure of NbCl ato In the latter formula the slightly higher order of magnitude with re- V spect to the concentration, of NbCl at which the activation energy of the process markedly decreases with decomposition of NbCl on NbC surface, as compared with Nb surface, may be attributed to the virtually thal absence of inhibition of the re- action by Cl in the case of deposition of HbC. It appears that the reason for this lies in the different catalytic properties of Nb and NbC. A comparison of the fin- 4ings on specific weight gain within 0.5 hr indl_qptes that in the presence of partial saures of NbCl amounting to 0. 78*10-2 - 6- 10'_4 atm the deposition rate of ;NbC is time-% pre independent. This, as well as the sufficiently high activation energy ~f the total process (33 kcal/mole) shows that in the 1500-18000K temperature range the rate of the total proc2as is limited by the surface che6icil rie'a'ctio"n-s.

On the basis of an analysis of the isothermal carburizatioli curves, they determined the influence of the temperature., the porosity of the graphitep the atmosphere of the furnace) and of the allaying on the carburization process. A logarithmic equation for the kinetics of the carburfiation in obtained by trial and error. The viscosity of the liquid titanium increases with increasing catbon concen- tration, first slowly and then rapidly, this being connected with the release of carbide-phase particles from the liquid. Data are obtained on the viscoGity of alloys" of titanium with Fe, Si, Ni, Al, Mo, Zr, Cu, and Co. The surface tension v of Ti was Imeasured by the method of maximum pressure in the bubble. The carbon increases the a Card 1/2 1 UN-. 669.295.154-. (532.13 + 532.691 ACC NRt )dC635413 of titanium. An equation is obtained for the capillary penetration of liquid titanium; under conditions when iz interacts chemically with the graphite. The carburization, process is determined by the Initial stage of the external mans transfer. An equation! relating the mass of the drop with the area on which it spreads is obtained. The re- sults of the calculation by means of this equation are compared with the experimental data on the spreading of liquid titanium and alloya over graphite with different pro- perties. Sufficiently good agreement between the calculated and the experimental data is obtained. 6 illustrations. M.

A study of the disintegration of supersaturated solid sol- ution of tungsten carbide in titanium carbide carried out by one of the authors'showed that this piocess in its early stage is accompanied by'an increase in the intensity of the (200) diffraction line of the solid solution. This increase could only be interpreted as caus 'ed by a decrease in the size of mosaic blocks of.titanium carbide due to the influence of par- ticles of precipitating phase.

Metallurgiya, 1959, .Nr 2, PP 9-14 (USSR ABSTRACT; The reduction of the iron ores in layers has a complicated kinetics. The rate of the reduction process depends on the crystalline transformation of the ferric oxide in the layers. The degree of reduotion is detected by a gravimetria deter- mination of the ore or by the measurement of the vapor developed. The dependence of the reduction process on -Atlemperature was investigated and is shown in figure 1. The curves in figure I show the course of a reduction in the case of a temperature rise which is expressed by the dopendence U = HSW /k. The kinetics of a reduction process of the Iron 0 in layers was investigated at 400 0 and 8000 and given in figure 2 (a - b). The influence of the rate of flow of the Card 1/2 reduction gas on the reduction of ferric oxide was investigated Some Kinetic Rules in the Reduction of Ferric Oxide With Hydrogen In Layers in the course of 30 minutes at 800 0 and Is given in figure 3. It was found that a lose of unused reduction gases occurs with the rise of'the rate of flow. Thus an experimental detection of the optimum rate of flow of the reduction gas is apparently necessary. There are 3 figures and 2 Soviet references.

TITLE: Determination of the (.ptimum composition of nillco-chromane and its application in alloying 14 Xre (14KhOS) grade steel PERIODICAL: Stal', no. 7, 1962, 615 - 616 TEXT: Tests were carried out (with the cooperation of A.S. Rabinovich, G.T. Duzenko, .;*.V. Pai'chlk, M.I. Vaynshtok, P.L. Konstantinov, et al.) on the application of silicocnromane (with 15 - 18% Si, 25 - 40% Ml and 25 - 35% Cr) in alloying 14KI-W grade steel. (The application of this ternary alloy was pro- posed by V.F. Mazov, I.S.,Viarakhovskiy, I.M. Leykin, A.A. Khomutov, A.A. Podgo- rodetskiy.) Silicochromane for the tests was p1roduced from ferromanganese, fer- rochrome, ferrosilicon, etc.j the teat steel was smelted in a 10-kg induction furnace and in 15-ton and 220-ton opoi-hearth furnaces. Besides testing ferro- chromane with various percentages of the main components, th,'A Investigatfons al- so covei-ed the possibility of adding this alloy to the steel without its prevl= Card 1-3 S/133/62/000/007/003/014 Determination of the optimum composition .... A054/A127 reduction. When ferrochromane was added to the bath without previous reduction, the burning out of manganese was 35%, that of silicon 80 - 85%,.while, when it was added to the reduced bath the corresponding values were not more than 4 - 5 and 45 - 50%. The burningloss cfchrome is not greatly affected by the degree of bath-reduction. By reference to laboratory tests, silicochromane with 32.- 34% 141n, 35 - 36% Si and 18 - 19% Cr was used In the pilot plant tesis with a 15-ton open-hearth furnace. In these tests silicochromane replaced silicomar;ganese in pre!-minary reduction and ferrochrome + ferromanganese In alloying. The burning loss cf manganese was 5 - 7%, that of silicon 50 - 55% and of chrome 16 - 18% In this zest series. When 50% of silicochromane was added in the furnace and 50% in the ladle, the losses of silicon were decreased'to 42% and the total amount of thealloy required for reduction and alloying dropped by IC%. The loss of manganese increased to 15%, while the burning 1cos of chrome remained unchanged (15%). Similar results were obtained for the 220-ton furnace. The optimum com- position for silicochrome was found to be 35 - 38% 14n, 32 - 35% Si and ZI ~- 23% Cr. The distr1bution of the main elements In the helght of the ladle was more uniform than with reduction accordingto the conventional methods.. Th) amount of gases also decreased when silicochromane was used. As to nonmetallic inclu- Card 2/3 S/133/6Z/000/007/003/014 Determination of the optimum composition .... A054/A127 sions the metal reduced by silicochromane showed silicate inclusions mainly In the skin of the ingot bottom, evidently because they could not float due to the lower liquidity of the metal caused by the addition of great amounts-of ferro- alloys In the ladle. This, however, can be corrected by using exothermic ferro- alloys. There is 1 figure. Card 3/3 AUTHORS: Khitrik, S.
