microsections and the Dresence of the intergranular
constituent. The hardiLe ss-compo sit ion curve is the normal
type for metals forming unlimited solid solutions.
The plasticity decreases with increase of the second
component (Figure 4, Curve 4)-, especially in the region
40 - 601% V where the tensile strength is 100 - 150 kg/mm2
The greatest plasticity is shown by pure molybdenum.
The electrical resistai),~,e-composition curve at room
temperature is shown in Figure 5. Thia curve is similar to
the hardness c-j-rve with a maximum of 50 40/cm at 601/0 V.
The results obtained confirm that V &ad Mo form a continuous

ABSTRACT: The microstructure, hardness, plasticity, strength and
susceptibility to oxidation of vanadium-tungsten alloys
in the whole_range of concentrations was investigated.
The following starting materials were used:
vanadium, 98.6% V1 0-3~-D C, 005% oxygext, 0.2% nitrogen,
0.06% su~ph& end less than 0.4o' of metallic admixtures;
tungsten, 99.95% Wo, 0.032%, Mo, remaining oxygen and
nitrogen. About 40 g samples of alloys were melted in
an are furnace with non-consumable tungsten electrodes in
a medium of helium under pressuxe of 0.5 atm. In all
cases the content of tungsten was 1% higher than in the
Card starting charge. Cast alloys were annealed at 1100 OC
1/3 for 500 hours in double quartz sheaths, evacuated and
sealed. Specimens for the investigation were prepared

by anode cutting with subsequent polishing. The
solidus -temperatures-were determined by the d-cop method,
metallographic and X-ray analyses by the usual methods,
hardness by the Vickers apparatus, plasticity and
strength on compression of specimens 4 x 4 x 6 mm in a
"Gagarin" press, and the suseeptibility to oxidation on
heating in air by the gravimetric method (increase in
weight, or decrease in weight after mechanical or
chemical removal of the scale formed). In some cases
the scale was chemically analysed. On the basis of the
results obtained the equilibrium diacTam of the system

in the compression strength. Further increase in the.
content of tungsten causes changes in properties,
characteristic for systems with continuous solubility
in the solid state. Vanadium decreasas the resisbance
of tungsten to oxidation. At temperatures between 700
and 1100 OC all alloys as well as starting metals are
strongly oxidised and require protection (Fig 3). The
microstructure of annealed vanadium-tungsten alloys is
shown in Fig 2.

chromium (99.900 Cr, 0.02 Fe, 0.03 S1, 0.02 N, 0.002 H, 0.0023 0),
Alloys were arc melted (non-consumable tungsten electrode) under
helium, each ingot of 50 g being remelted four times and analysed.
Compositions of the charges and alloys are shown in the first two
main columns of a table. Solidus and liquidus temperatures were
determined under argon in an apparatus constructed in the
Laboratoriya splavov redkikh elementov 1,81E'r AN SSSR (Laboratory of

determined with an optical pyrometer calibrated under similar
conditions against melting points of pure nickel, titanium,
zirconium, niobium and molybdenum. Liquidus temperature was the
reading when the specimen lost cohesion, the solidus, that when
a hole drilled in the 4 x 4 x.15 min specimen fused over.
Curves I and 2 in Fig.1 show plots of these temperatures against
wt.00 Cr (the relatively low value for vanadium is due to
impurities). Microstructure was studied and hardness measured on
the cast alloys and alloys annealed for 100 hours at 1100 OC in
evacuated quartz capsules and slowly cooled. The hardness (Hk,
kg/mM2) results are shown in Fig.l.; curves III and IV correspond
to the cast and annealed states respectivelyg and curve V gives
hardness at 1000 OC (annealed alloys). Hardness was determined
with a 50-kg load on a 11pobedite" cone, in argon at the high-
temperature which was measured with -a Pt/Pt-Rh thermocouples
Electrical resistivity of annealed 4 x 4 x 15-20 min specimens was

TEXT: Aluminothermic V (96.5%,), carbothermic V (gE%), and electrolytic Cu
mark M 0 (MO) were -taken as the starting materials. The alloys with Al were
charged with an addition of Cu to the alumothermic V, and addition of C in the
carbothermic V. The 0alloys were smelted in an are furnace in a fie atmosphere,
homogenized at 1,000 C for 100 hours, and Investigated by the methods of thermal ,
microscopic and X-ray structure analyses and by the measurement of the mechanical
characteristics. The vertical sections were constructed of the V vertex of the
system V - Cu - Al and V - Cu - C at a constant composition of 1.5% Al and C.
The solubility of Cu in the aluminothermic V at 200C is about 7.5R,", and as the
temperature increases so does the solubility, reaching a maximum (9.4% Cu) at
1,5300C. In the system V-Cu-Al one observes a wide region of lamination In

temperature Is equal to 1,5300C. The melting temperature of V in Cu is 1,1200C.
The limiting solubility of Cu In alloys V-C at room temperature is about 1%,
and at 1,5750C - about 3.5%. The addition 0of C raises the temperature of
monotectic equilibrium from 1,530 to 1,575 C and extends the region of immisci-
bility. The lamination in V-Cu-C alloys is observed beginning from 11% Cu. Cu
raises the hardness and lowers the ductility of V. In V-Cu-C alloys-a second
V-phase was found with a hexagonal lattice; one supposes that it is the r-phase.

TEXT: The object of the present investigation was to explore
the DossibIlities of achieving the removal of N, 0 and S from
vanadium and thereby improving its placticity, by addition of
cerium to vanadium melts. Both alumino- and carbo-thermic
vanadium was used in the preparation of experimental samples
(10-15 g in weight), which were melted in a tungsten arc furnace
with water-cooled copper hearth in an atmosphere of pure helium
at 0.9 atm. The proportion of cerium added varied from 0.2 to
50% wt. Each sample was remelted four times to ensure
homogeneity of the metal. The buttons obtained in this manner
were mechanically descaled and the vanadium-rich layer, separated

from the cerium layer, was used to conduct chemical and gas
analyses, metallographic examination, hardness measurements,
compression tests and cold rolling tests. The conclusions were
as follows. 1) Cerium has limited solubility in both solid
and liquid vanadixim. The liquid miscibility gap begins at
0-2-0.3 % wt. Cc, and the solid solubility of Cc in V is less
than 0.1 % wt. 2) Addition of Cc to V melts brings about a
considerable decrease in its oxygen, nitrogen and sulphur content
and causes a corresponding improvement in its plastic properties..
This is de~monstrated in Table 3, where some data for Ce-treated
carbo-thermic vanadium are given. It should be pointed out that
complete purification of the melt cannot be achieved in one
operation since a state of equilibrium is reached between liquid
vanadium, cerium, and the slag; further decrease in the oxygen
content in vanadium can be attained only by repeated removal of
slag and addition of cerium until the required degree of purity
of the melt is attained. Sample melt in Table 3 underwent five
such operations. 3) The carbon and metallic impurities content
in vanadium is not affected by Cc additions. 4) When large Ce

additions are required to purify heavily contaminated vanadium*#
difficulties may arise in melting the charge, owing to the
formation of a thick layer of (mainly Ce02) slag which either
weakens, or even breaks, the arc, particularly when large
(500-600 g) batches of vanadium are treated.

ABSTRACT: Of the three metals in group V of the periodic table, most attention, at
present, is being given to niobium and vanadium. These metals are quite pliable in the
pure state, but their properties are markedly affected by traces of C, N, 0 or 11. Their
purification is therefore unusually important, and one of the most promising techniques i
for their purification is reduction of their oxides or nitrides with an active element such as~
Mg. The present investigation concerned the interaction of -vanadium and niobium with
magnesium. On the basis of studies of the macro- and micro-structure, X-ray and thermal
analysis, as well as hardness and micro-hardness determinations, the phase diagrams of
the V-Mg and Nb-M systems could be plotted. Both systems showed immiscibility in the
liquid and solid stal, including practically the entire concentration range. Very narrow

areas of solid solutions are formed on the vanadium and niobium sides. The solubility
limit of magnesium in vanadium and nioblum at 20C is 0. 01 and 0. 04%, respectively-, at the;.
monotectic temperature (1860C for V-Mg and 2380C for Nb-Mg), the corresponding figures
are 0. 03-0. 04 and 0. 05%, respectively. This does not significantly affect the structure of
V and Nb. Vanadium and niobium do not dissolve in solid magnesium. In liquid Mg the
solubility of vanadium at GGOC is 0. 06%, increasing to 0. 3% at 950C, while the solubility of
niobiumlnrnagnesiumatl2OOCisO.05%. Melting with magnesium leads to reduction of
vanadium and niobium, lowering their strength and hardness and increasing their plasticity"
However, reduction of vanadium and n1oblum is hampered by the high vapor pressure of
I magnesium and the difficulty of removing the slag. Orig. art. has: 3 figures and 3 tables.

ABSTRACT: The article considers the possible strengthening of six differeunt NI-V
alloys by secondary alloying elements (TI, Al and Ko) and heat treatment. Cast
specimens were successively annealed at 1200C for 5 hours, water quenched at 900-
1050C and tempered at 20-ICOOC for from 25 hours to two months. The microsections
were Investigated, as well as the electrical resistance, and some specimens were
subjected to X-ray analysis. Fig. I of the Enclosure shows the effect of tempera-
ture and temp6ring duration an NI-V alloy hardness, while Fig. 2 shows the varia-
tion In relative electrical resistance of the alloys when heated at a constant rated
The author cites the conclusions of W. ?. Pearson and W. Hurree-Rothery with regard
to these processes. The Investigation shmad that secondary alloying with TI and
Mo significantly !ncreases the hardness of NI-V alloys at higher temperatures, due
