ABSTRACT: The authors Investigated the electroconductivity of phase components of
the chromium-silicon system In which the properties, especially in a liquid state,
have not been adequately studied. Measurements were made within ranges of 5-19250C
.for chromium,.700-18300~ for silicon, and 25-18810C for CrS12* Measurement results
are presented In graghs. The authors found that a specific resistance of electro-
lytic chromium at 20 C was 14.1 p0hn and rapidly increased with temperature* reach-
ing 145.5 vQ at 18000C. This differed somewhat from previous results. The tempera-
ture dependence of the el*ctrocooductivity of pure silicon agreed quit,s well with
previous data.. Chromium diallicido has an alectroconductivity In a solid state

increasing temperatures lovered the parameters of austenite pe=eability, as calcu-
lated, from the high-temperature sections of the polythem to values vhich approxi-
mated those calculated from the low-temperature sections. In order to obtain data
which would supplement earlier studies of the imperfections accounting for the
anomalous changes in hydrogen permeability, the authors investigated the recovered
hardness during a 30-minute annealing of 10 x 10 x 2-5 specimens reduced by 27%.
At 500 C hardness was recovered by 18% and activation energy of pe=eability by
32%. The authors conclude that the recovery of diffusion characteristics occurs
within a lower temperature range than the recovery of hardness. Hydrogen pezze-
ability parameters, as affected by plastic deformation and annealing, have an
exponential relationship p i~-, expE analogous to that determined in earlier studies
for phase-hardened austeni?e. Experimental results are explained in the light, of
an earlier theory on crystal lattice imperfections which affect diffusion by en-

ABSTRACT: purpose of this article is to investigate in 'greater
detail the structural characteristics of carbides of transition
group IV metals of the type' Me(IV)Cx and of group V metals of the
type r-le(V)(' and specifically the space distribution of vacancies
in them. 6A the basis of the model in which the valence of C. atoms
in cubic carbides of transition metals of groups IV and V is always
satisfied by the metal atoms surrounding them it is shown that the
formation of vacancies in carbon sublattice MeCx increases the num-
ber of electrons of the unscreened Me-Me bonds which pass through
the C defe(:t. Assuming that 113 of the electrons of unscreened Me-
Me bonds are localized in the vacancies the article considers their

regions of VCX and Nb the adjacent distribution of C vacancies is
less probable than inCAe(IV)C , although even in the latter compounds
it is unfavorable energywise.x A comparison of Me-Me distances in
defect lattices of carbides, with parameters calculated on the basis
of the number of electrons in the Me-Mo bond, along with the data
on space distribution of vacancies enable the explanatAon of the

formation of granular cementite, the permeability of 34KhM4 steel increased by

most perm-,able to hydrogen was found to be that of graaular cementite. The

ABSTRACT: A study was mad-) of the temperature dependence (20-1110 C) of the
hydrogen jvrmeability, the yield and tensile strengths, and the hardness of an
Fe-Ni alloy (28. 6116 Ni) in equilibrium and hardened conditions. Phase hardening
of the Ni austenite significantly increased its hydrogen permeability and the ener-
gy of activation E of this process: at 350-300 C, E (',~45 kcallmol) was about
1. 5 times greater than E for austenite in equilibrium conditions. Recovery of tile
diffusion cha racte ris tics of the alloy was especially intense in the 400-500 C
range Increasing the annealhig temperature further to 700-850C had little effect

on permeability and E. Phase hardening significantly increased yield strength,
tensile strength and hardness, but had only a little effect on the modulus of elas-
ticity of the alloy. Recovery of mechanical char teristics developed strongly at
,~Vc crease of
-600-700C. The increase in electric resistance with temperature in
the phase hardened austenite stopped at about 440 C. The coincidence of the
recovery of' electric resistance and hydrogen permeability is attributed to the
possible hypOrsensitivity of these processes to similar defects. The mechanical
t
and diffusic-nN'tharacteristics are sensitive to different defects in the crystal lat
tice. The first is apparently d0ermined by the subgrain structure while the
second is determined by the nature and distribution of vacancies, dislocations
and other similar defects in the crystal lattice. Orig. art. has: 3 figures

the composition T&C is nearly linear, characteristic of metals, which
indicates a low tempOlture sensitivity of the energy spectrum of electrons in the
carbides. Av for the concentration dependence of the electric conductivity of
and 'Y-phases of the Ta-C system, this is determined by the relative role of two
factors: the variation In the electron concentration within the conduction band
(Me-Me band) and the variation in electron mobility with decreasing concentration
of vacancies in the carbon sublattices of these carbides. Thus, the appearance of
a defect in the carbon sublattice is accompanied by a decrease in the amber of the
valenooelectrons of Ta atoms participating in the bondings with C atoRs. As a .
result, the electron concentration in the Me-He band, which is responsible for the
electric con~uctivtty of the carbide, increases.

ABSTRACT: X-ray diffraction, metal-lographic, and densitometric investigations of A
series of Cr-Ge alloys containing 2.0 to 31.0 at % Ge showed that substitutional
solid solutions based on Cr and the intermetallic compound Cr3Ge are formed. ~~e
concentration ranges of single-phase existence of these solutions at 11500C ext(!nd
approximately up to 3.0 at % Ge for the Cr-base solid solution (a phase) and fron
23.1 to 25.7 at % Ge for the Cr3Ge-base solid solution (6 phase). The solubility of
Ge in Cr at 11500C Is approximately 30%. Increase in the Ge content of the S Phase
is accompanied by a rise in thermo-emf and decreasing microhardness. Changes in the
lattice constant a of the 0 phase and in the density of the alloys with ch:ingii:7, ~;er-
manium content were determined. Orig. art. has: 4 figures.

TITM Kinetics of the reduction of lower niobium oxides with carbon :3
SOURCE: Zhurnal prikladnoy khimii, v. 38, no. 10, 1965, 2174-2181
TOPIC TAGS: niobium compound, chemical reduction, carbon
ABSTRACT: Pressed NbO2 + C and XbO + C powder mixtures were heated at 1200-16000C,
and the kinetics of reduction of NbO2 and NbO were studied In a vaccum as a function
of temperature, compacting pressure and presence of additives (K2CO3, Na2CO3, CaCO3,
T102). The degree of reduction stu=did as a function of temporature, time, type
of carbon and amount of r hite e ction process was found to be complex.
Under certain conditions, n addition to the usual two-stage mechanism of direct re-
duction, intesvmdiate niobium carbides form. Because of its diffusive nature, the
decomposition of these carbides is kinetically hindered to a considerable degree.
While the initial stages of the interaction the rate-determining factor is the gasi-
fication of carbon, during the final stages the rate-determining processes involve
diffusion. It is concluded that In order to accelerate the reduction, it is neces-
sary to avoid the formation of niobium oxycarbides, a. g., by maintaining a high vac

alloys with titanium and zirconium. Unlimited series of solid solutions of niobium
with a-Ti and S-Zr are formed in these systems over a wide temperature range (from ap-
:proximately 1000-110011C to the melting points). The dimensions of component atoms in
lalloys of niobium with titanium (as well as their lattice parameters) are extremely I
!close (rN =1.45 A, rT,=1.46 A). The atomic radii of the components in the Nb-Zr sys-

ieffect which the size factor has on the diffusion mobility of niobium atoms. Homoge-
;neous $-phase alloys were melted with various concentrations of titanium (5-0, 15.1,
129.8 and 40.9%) and zirconium (5.0, 15.1, 214.2 and 36.1%). The coefficient of self-

,an increase in the concentration of alloy g elements raises diffusion mobility while
,reducing the activation energy and the 4,xponential fact r. The addition of niobium
!to titanium reduces the activation energy more rapidly than in the case of Nb-Mo alloy
The activation energy in Nb-Ti all-o-y-s-c*Fainges more rapidly with the preexponential fac
.Uor than in Nb-Mo alloys. This is probably due to the difference between the atomic
Xatios of the components and the length of the elementary displacement as well as to
the activation spaces produced by the impurity atoms. In spite of the considerable
~difference between the atomic radii of zirconium and niobium, the effect of zirconium
ion activation energy and preexponential. factor is much weaker than that of titanium
This is apparently due to the fact that the rate of diffusion depends not only on the
!atomic radii but also on the potential fields and vibration frequencies of the atoms.
!It is shown that there is a simple linear relationship between activation energy and
ithe logarithm of the preexponential factor. There is a regular increase in 'the corre-
!lation factor with the dimensions of the alloying atoms (Mo, Ti and Zr). Orig. art.

the tantalum-c&rbon system depends substantially on their compo3ition (the carbon

ABSTRACTI: The kinetics of the reaction of powdered and massive vanadium with carbon
monoxide were studied at various pressures and temperaturesp for which the reaction
rates were determined. The activation energy for both forms of vanadium was found
to be 35.3 kcal/mole at 1400-15000C. X-ray and metallographic analyses indicate
that a cubic oxycarbide 61 Phase M.G~) is formed on the surface of the samples,
and an oxycarbide Y9 Phase (:V2qKOjr) is located under it. This shows that the diffu-
sion front of carbon moves faster than that of oxygen, since,, if the opposite were
true, an oxide phase instead of a carbide phase would be located at the metal bound-
ary. Tho 60 phase accumulates on the surface of the sample in the form of a loose
layer which ametimea psel& off on oooling, whereas the layer of the y" phase remains

approximately stationary. It is concluded that the diffusion of carbon and oxygen
..and the reverse diffusion of vanadium through the y' phase determine the kinetics
of oxidation of vanadimm by carbon monoxide. Orig. art. has s 6 figovap 2 taUes
