structure. The results Indicate that the observed.higb resistivity of the alloys is
connected with the structure of the metastable y' phase and depends on the nature of,
the alloying elements. The necessary condition for obtaining the y' phase is quenchin
from the unstable 0 phase which exists In such alloys, The resistivity decreased as
a rule with increasing atomic number of the additive, and increased very strongly with
increasing atomic percentage of the additive, This report van presented by Acadenicii

Title : Penetration of liquid titanium into graphite.
Periodical : Izv- AN SSSR, Otd. Tekh. Nauk 5, 129-132, May 1955
Abstract : This investigation was made necessary because with the
present method of melting titanium in a graphite crucible
there was too much loss of the metal by its penetration
into the graphite and also its seepage completely through
the crucible and onto the heating elements. This caused
the breakdown of the heating furnaces. In conclusion the
author states that ordinary graphite crucibles are too
porous and cannot be used. It is recommended that graphite
crucibles with higher walls and smaller bases, made of the
lowest porosity graphite, be used in melting titanium and
that the metal be kept in the crucible, in its molten state,
for minimum periods of time and at'the lowest temperatures
possible, above melting point. Graphs, tables. one refer-

ABSTRACT: The titanium was molten in graphite crucibles which were
sufficiently dense to hold the molten titanium for twenty-
five minutes without appreciable penetration of the metal
into the crucible walls. The authors used the method of
Meyer which was further developed by Shvidkovskiy, Ye.G.(2)
and was intended for measuring torsional oscillations of a
cylinder with a liquid suspended on an elastic thread and
then determining the viscosity from the logarithmic damping
decrement and the period of oscillation of the cylindrical
crucible suspended on the thread and filled with the molten
metal to be investigated, The authors used ahigh tempera-
ture viscosity meter embodying a vacuum resistance furnace
with a carbon-grap&te heater, the design of which was
described by Yelyutin et alii (3), a sketch.of which is
Cardl/2 shown in Fig.1, p.96. The estimated measuring error was
5 to 6% and the Ti used in the experiments was produced by

the magnesium-thermal method and remolten in an are furnace;
it contained less than 1% admixtures, i.e. max 0.2% Fe,
max 0.2% Si, max 0.4% 0, max 0.1% N. The results obtained
in five series of measurements at temperatures between
1730 and 1920 C are entered in Table 21 p.100 and it can be
seen from the obtained data that the viscosity decreases
from 0.89 to 0.37 centistokes if the temperature increases
from 1730 to 1920 C. Calculated results show that the free
energy of the viscous flow is a linear function decreasing
with temperature. The heat of evaporation/energy of
activation of the viscous flow ratio equals 2.7.

ABSTRACT# The author gives a description of the educational conditions
in Russia before and after the Revolution. He states that the
development of higher education made enormous progress during
the post-revolution period. He indicates some figures relating
to this evolution. The number of students in 1940 amounted to
811,000; in 1950 to 1,247,000; in 1957 to 2,001,000. Compared
with 1919 the number of students increased by 16 times, especi-
ally in the fields of engineering, transport communication,
agriculture, forestry, and economy. The creation of vuzes in
remote areas was considertbly-activated. The organization of
new vuzes and the expansion of those already existing was car-
ried out in the Ural, western and eastern Siberia, in the Far
East and in Central Asian republics. The number of students
increased in 1956 by 1.6 times compared with the figure of 1950
and bY 3.2 times compared with 1940. In tha eastern areas

other higher educational Institutions. In the Soviet Union
there is no republio without a national university and other
higher educational institutions. In 1956 the Soviet higher
and secofidary special educational institutions released
770,000 specialists, and during the last 5 years - more than
2,700,000. The Soviet Union has now 38 universities, and the
number of students amounts to 200,000. A characteristic
feature of the higher schools is the uninterrupted endeavor'
to improve their education methods.

The Interaction Betneen Nickel-Vanadium Alloys and Refractories
To determine the suitable refractory for the nickel-vanadium
alloys the interaction between the alloys and the refractory
wan Investigated, Vanadium is a comparatively activP metal in
the melt and reacts energetically with the refractories of the
crucible, bringing impurities Into the metal melts. In the re-
actions mainly VO reacts. In the interaction between VO and
the oxides of refractories also V20 3 is formed. The lower sta-
bility of ZrO2 as compared to vanadium melts is probably a
consequence of the reaction 2ZrO + V ~FkZr 0 + VO.

By means of radioactive indioatorn the character of the ln'~er-
action bet-ieen the refractory and the liquid metal alloy with
a vanadium content of 30% was determined. ZrO . was used as r,~--
fractory to which the radioactive isotope Z ~5 'was added.
The investigations showed that non-metallic impurities can be
avoided only if the melt to not overheated and is left in the
state of melting for as short a period an possible.

ABSTRACT: The influence of the temperatures on the reaction velocity
of the reduction of metal oxides with carbon was in-
vestigated. Activated and non-activated charcoal were
used as reducing agent; it had been obtained by the inter-
action of the gas mixture CO 2+ 04o 2 with metallic
magnesium. The initial temperature of the interaction
between carbon and motal oxides, as for instance MoO 39

an increase-of the rate of the reduction process. The
kinetic curves obtained show that the reduction processes
of the oxides have an autocatalytic mechanism.Vased on
the results obtained the apparent activation enerCj
of the reduction processes of the oxides with metals

ABSTRACT: In order to determine the fluidity of nickel-vanadium alloys of a
content of 25, 30, and 35 % of vanadium, the method of pouring the
alloys into molds of the Ruff-type was chosen. By this method, the
tests can be carried out in vacuum or in a neutral atmosphere. The
metal was melted in crucibles of beryllium-oxide with argon in a
high-temperature resistance furnace with a graphitic carbon heater.
A special furnace structure as shown here allowed the metal to be
poured into crucibles without disturbing the tightness of the fur-
nace. The experimental method of Yelyutin and Maurakh (Ref 6) was
c=plofred to determine the specific gravity of the smelt. This for-
merly used method is rather simple but reliable.- By investigating
the fluidity of the nickel alloys of a vanadium content of 25, 30,
Card 1/2 and 35 % It was found that these alloys showed a rather good fluidi'W;

of obtaining an education without ceasing to work in one's
profession has been considerably expanded. Out of 2%lOO,OO0
higher school students, 880,000 are being trained by the
evening and correspondence system. In recent years higher
education has developed vigorously in the eastern provinces
of the Soviet Union. At present over 500,000 student a almost
25 % of the entire number, are being trained there. in 1950,
there will be established in the East the Khabarovskiy avto-

Temir-Tau. In the light of N.S. Khrushchev's speech at the
13th VLXSM Congress, the question of shop practice must play
not only an instructional, but also a great educational role.
It is considered expedient and necessary, beginning with the
1958/59 school year, to considerably increase the admission
to vuzes of persons with not less than 2 years experience in
industry, agriculture, and other branches of the national
economy and culture, who are recommended by the social
organizations of theenterprises where they are working. The
new,ruleo of enrollment into USSR higher schools this year
provide.for admissiont with work being discontinued, of persons
awarded a gold or silver medal on graduating from secondary
achools or of excellent pupils of secondary.special schools,
who are in the top 5 % of the graduating class. The encourage-
ment of youth with shop or personal experience does not pre-
vent capable young.people with secondary education from enter-
ing the vuzes, even though they have no shop practice. The
now rules of admission providelthat 20 % of,adminsions be
allotted for general competition in case applications of

ABSTRACT: The authors investigated the effect of combined chemical and heat
treatment (CHT) of the surface of specimens of a TiC base (71.5%
TiC) alloy cemented with a NiAl compound containing 54 atom-1/6 Ni
and 60 atom-16 of metallic Nb, Zr, Cr, or Be on the resistance to
scale formation at 1150 - 12500C. The CHT consisted of annealing of
the specimens covered with a 50:50 mixture of ZrO2 and alloying
metal and 1% NH4CI in an H2 atmosphere at 15000. Saturation of the
surface with niobium. and zirconium does not improve the resistance
to scale formation of TiC - NiAl alloys - GHT with beryllium and
chromium increases the heat resistance by 19007o and 2001o, respec-
tively. The authors note that a change in the procedure of saturation
Card 1/2 of the alloy surface with chromium (for example at 11500 temperature

SOV/137-59-1-575
Effect of Combined Chemical and Heat Treatment on Heat Resistance of Alloys
in an atmosphere of air) has no effect on its resistance to scale formation. How-
ever, CHT conditions should remain constant (15000 temperature for 0.5 hour) for
Be, because any difference in the interaction between Be and TiC and NiAl re-
sults in a different concentration of Be in these phases. The authors submit that
during longer CHT Be reacts predominantly with the NiAl and that the TiC grains
become exposed, which lowers the resistance to scale formation of these alloys.

for TL3 carbide, 6.16 &/cm3 for Ti6O carbide. The alloys were prepared of Ti-
carbide powder and complex Ti-W-carbides. Powders of the initial material
were mixed in alcohol for 48 hours, dried in air, pressed into briquets and
dri,4d In a vacuum cabinet. Sintering was carried out in argon and hydrogen
atmosphere, in a laboratory vacuum furnace with a graphite shaft and In a
TVV-2 furnace. Optimum sintering conditions were determined from the results
of measuring the strength, hardness, speciflo weight, and changes in the com-
position of the alloys. Greatest changes in the composition were otserved in
sintering Ti-carbide-base alloys In a vacuum. Loss of individuall ccmponents
through sintering was oaloulated after ainterirA in a vacuum, hydrogen and
argon for 1 hour at 1,7000C. The loss amounted to 15% TI, 67% Al and 13% C
of the total amount of the component in the alloy prior to BinterIng.
Minimum loss was observed in sintering in pure argon. Table 2 contains the
composition of the T100B (15) alloy prior to and after sint-ering under
different conditions. The strength of alloys during bending was investigated
with the aid of a special device on a two-ton testing machine at high temperatures

without shielding atmosphere. Figures 1 - 5 show the effect of the sintering
temperature on the alloy strength during bending. Highest strength of Ti-
carbide'base alloys was obtained by sintering for I hour at 1,9000C. A raise
of the sintering temperature up to 2,1000C did not affect the strength (Figure
1), although shrinkage and density of the alloys increased. Extended holding
up to four hours entailed decrease in strengthl holding time reduced down to
0.5 hra entailed a decrease in density. The authors oontradict the statement
made in [Ref 41 that the optimum temperature of sintering for a TIC-NiAl alloy
was 1,6500C. They proved experimentally that alloys of highest strength and
density.were obtained at 1,9000C and above. It was-establiahed that optimun
mechanical properties of the alloys depended on the optinram amount of the
licraid phahe during sintering. To obtain this, alloys with a lesser content
of'binder should be sintered at higher tempgratures which ~ralse the amount
of the liquid phase due to the dissolving of the carbide component.

TEXT: An Investigation was carried out with titanium and titanium-tungsten
carbide powder bound with NiAl and CoAl compounds. The effeit of the composition
and of different quantities of the binders was determined. The results are illus-
trated by curves. In case of titanium carbide with 15 volume % NiAl the binder
composition bad no effect on the alloy strength at room temperature, but a pro-
nounced effect was observed at 1,0000C. Alloys bound with binders of stoichiome-
tric composition proved strongest, and alloys bound with NIA1 with 60 atomic %
Ni weakest. Alloys with over 025 -vol=e % NiAl have the maximum strength. The
strength of TiC-NiAl at 1,000 C was in all cases higher than at room temperature,
which not fully corresponds to statements made in a previous investigation (Ref.3).
Me alloy with high NiAl content had a considerably higher heat resistance than
with low NiAl content. Titanium- tungsten carbide T-15 (T-15) and T -60 (-1-60) were
bound with CoAl with 60 atomic 56 Co, with 10 and 15 volume % CoAl, respectively.

A higher strength was observed in alloys with 15 and 20 volume % of NiAl at 9000C
than in cold which is explained bv higher plastioity of NiAl at c)OOOC. At. higher
temperature the alloy strength dropped. The high strength of TIC-NIAl alloys in
hot state Is apparantly also due to the plasticity of NIA1 and stress redastribu-
tion. This phenomenon had been observed by G.S. Kreymer, O.S. Safonova and A.I.
Baranov (Ref. 4) in WC-Co alloys (maximum strength at 2000C due to softened coball-)
The following conclusions were dravni: 1~' Titanium carbide alloys bound with NiAl
j -
have higher bending strength at 1,0000C than at room temperatire. 2) Titaniim-
-tungsten carbide alloys with 16% titanium carbide bound by NiAl retain their
strength up to 900-1,OWOC, 3) Titaniiur-tungsTen carbide bound with CoAl has a
higher strength than analogous alloys bound with NiAl. 4) At room temperature
the strength of titanium carbide alloys doeq, not depend on the composition of NIA1,
but at 1,OOOOC It does. At 1,OOOOC alloys bound with NiAl of stoichiometric com-
position have maximum strength. 5) The carbide base composition is Important for
alloys bound with NiAl. and CoAl. Alloys with pure titanium carbide and titanium-
tungsten alloys with high titanium content (64% T-10 have low strength at room

1959/1960, 1489 students learned in this special branch. From 1950 to
1959, 1322 students finished this special education, among them 700

the specialists also in the Khar1kov Engineering-Economic Institute$ in
the Moscow Mechanical Engineering Evening Institute, in the Moscow Poly-

machines" is given in secondary schools. At the same time an advance of
the quality of the preparation ahall be reached, theoretical and
practical educations shall go hand in hand. The establishment of books
is essential. A strengthened mathematical preparation of the students is
aspired. A research on the domain of mechanization on a broad bass is
essential. This research is performed already successfully at the

accompanied by a slowing-down in the increase of the electric
conductivity with temperature. From the point of view of the
Semiconductor properties, this corresponds probably to a
transition from i.mpurity- to intrinsic -conductivity of the oxides.

polymorphous transformation or to plastic deformation caused

TENT: Th emecbanism of reduction of metallic oxidles is
insufficiently understood, particularly fox- tenperatures below
7000C at which the speed of re,(.;encration of the oxides of carbon
is insignificant, hence new ;-.iethods of investigation are needed.
In this work the change in electrical resistance of the hiZhor
oxides of vanadium, molybdenum and tungsten was investigated at
-the temperature of their initial interaction with carbon.
Samples of cornets (2 x 6 x Ito mni) were prepared by pressing the
powdered oxides at 1.5 tons/CM2 and sintering in an atmosphere of
oxygen for 6 hours at 6oo"c (VP-05); 7000C (1)'1003) and SOG"C OWO~).
The electrical resistance of the samples was measured by a
compensating method using a high temperature four-point probe in an
atmosphere of argon at temperatures of 200 to 5800C (V205);

that the resistance of t1te samples has a typical semiconductor
character. A discontinuity occurs in the curves relating
electrical conductivity ,-Ind temperature and it is :010'.-In that the
temperature at wbich tiiis discontinuity occurs is approximately the
same as the temperature at which reduction of the oxides be-ins.
The effect of adding SiOq to V205 i-,ras also investigated. The
transition temperatures are: V-005, 373 to 430OC;
V205 + 0.08" SiO,-), 381*C; V205 + 0.17',o

V905 + 0-35% Si02, 11330C; 1,1003, 1115 to 11800C; wo3, 675 to 695DC.
Ii is also shown that the temperature for the initial reductIon
of the oxides depends on the width of the forbidden zone .'-Eo.
The larger /"Eo the highcr the transition temperature. The
addition of SiO2 raises the transition temperature of V`05 and
simultaneously lowers its chemical activity. There arz

TEXT: Although data on the electric conductivity of
titanium up to temperatures of 13000C have been published, similar
data relating t.o near-fusion temperature and to the liquid state
have not been published. An electrod6less method was applied for
measuring the resistivity of titanium. This is based on measuring
the stationary torsion angle of a sj~ecimen suspended on an elastic
thread in a rotating magnetic field. The stator coil winding of
the measuring instrument was provided with a high temperature
insulation and the coils were placed inside a water-cooled steel
housing. Graphite heater elements *ore used which permitted
obtaining temperatures tip to 25000C. The method of measurement of
the resistivity is similar.to that applied by other authors for
measuring the resistivity of molten metals. The temperature

of this paper, curves 2 and 3 are published values. For the liquid
metal t-i values were obtained: A - for melts produced in ThO 2 or

author points out that the data for liquid titanium at 18000C
(points A and B) are not entirely reliable and should be verified
with a crucible material less active towards liquid titanium than
the graphite, thorium dioxide, and beryllium'oxide used in these
experiments. From the test results the temperature coefficients of

TOM The object of the present investigation was to
study the effect of various factors (compacting pressure,
sintering conditions) on the internal -friction of green and
sintered copper-powder specimens. The test pieces
(70 x 5 x 0.5 - 1.5 mm) were prepared trom electrolytic copper
powder (20 - 30 It particle size), 99-915% purity, whAch had been
given a preliminary reducing anneal (2 hours at 400, C) in
hydrogen. The internal friction was determined by measuring
the amplitude of forced oscillations of thl'specimen near its
resonance frequency on an apparatus designed by one or the
present authors (a dekeription is given of both the equipment
.,.and experimental procedure)* Typical resuits are reproduced

Several co'i~clusions we*i"e reached; 1) Temperature-dependence
of internal'friction of green copper-powder compacts have
two peaks: a low-temperature peak associated with the grain-
boundary effect and a high-temperature peak associated with the
presence of oxygen; thp internal friction of green compacts

this can be attributed'to sintering taking place during the

4) On increasing the sintering temperature from 600 - 900 C
the height of the low-temperature peak increases and the peak'
is shifted toward s higher temperatures; further increase in
the sintering temperature brings,about &.decrease in the height
of this peak. These effects indicate chat on raising the
sintering temperature from 600to goo C the contact ar.ea
increases at a rate faster than the rate of the grain orowth;
on raising the sintering t emperatur e 'from... 900 to 1 000 C the
