ABSTRACT: The homogeneous crystallization Of solid solutions
results of two processes advancing simultanoo,_sly: (1)
deposition of new crystals whose compositions conform
with the solidus-liquidus equilibrium at any point of
the dropping temperature; (2) reaction between the mDiten
matter and the crystals formed earlier, whose composi-
tion must be altered to conform with the solid',is-liq~~_J,s
equilibrium at the particular temperature. The first
process is provided by diffusion in the liquid phase
and the second by diffusion between the solid and
liquid phases. Since the latter is a slow process, a

TITLE: Castings from Prittle "aterials
PERIODICAL: Liteynoye Proizvodstvo, 1Q59, Nr 3, PP 11~"-l LP
ABSTRACT: For the various branches of the industry it has ~-ecome
necessary to use materials resistant to high tempera-
turea and chemical influences. Such materials but are
difficult to cut and machine and are not possible to
form by pressure as V7ey do not have any elasticity.
The best method of workability for such materials is
casting. But the main obstacle for tle latter method
are the appearance of cracks caused by shrinkage aid
inner heat pressure of the casting. This dependance
between temperature and pressure of the core material
is represented in one drawing and is well known for
die casting and pressure die casting. Tt is necessary
that the core material has a greater coefficient of
Card 1/3 heat expansion than the material of the casting.
Castings from Brittle Materials
Graphite, carbon, coke, etc., or Rn ot-er
terial are suited as a core material, where t'~e core
T
material had been previously cast in aluminuw- _n all
cases pseheating of tle core material to ?CO 0r up
to 500, Celsius is necessary. When CAstinp complicated
shapes, like e.g. pistons, pouring of tl--e complete
shape is not possible. In such cases the core consists
of several parts. Cracks caused by Ve pressure ori-
ginating from the cooling-off of the material -re a
disadvantage too when casting brittle materials, like
e.g. cast iron with a high percentage of chromium,
silicium, diabase, etc. A table is offered list~rg the
deformations of the materials when cooling-off. 7uch
cooling-off shall be clone slowly and uniformly, and the
casting should not betaken from the mold too early.
The final solution of the experiments made revealed
that employment of the centrifugal castinp Fet~~Od

TITLE: On the Crystallization of a Solid Solution
PERIODICAL: Zhurnal fizicheskoy khimii, 1959, Vol 33, Nr 10, pj~ 2253 - 2256
(USSR)
ABSTRACT: The equilibrium crystallization of solid solutions is usually
represented as the sum of two processes, i.e. precipitation of
the solid solution along the solidus lines and interaction of
the precipitated solid solution with the liquid. The second
process is not mentioned at all in publications (D. A. Petrov
(Ref 1)), two possibilities are suggested (N. X. Vittorf (Ref 5%
or it Is incorrectly assumed that diffusion takes place only in
one direction, i.e. from the highly melting crystal component
into the liquid (I. V. Gorbachev (Ref 6)). It is shown here that
the average composition of the substance that passes from +he
liquid to the crystals during equilibrium crystallization may
running between the solidus and the
be defined by a curve c

solid solution and the liquid is brought about by transition of

ABSTRACT: The authors stuaied the effect of conposition of the starting maturial, a-W
of the speed and number of passes on the quality and purity of single crystals of
rhenium obtained by zone molting with an electron beam.2 The total amount of
impurities (some 26 elements , originally about 2 x 10 %, was reduced after three or
four Passes to about 3 x 10-~%, the limit of detectability. The atmoaphero (Vacuum or
hydrogen) had little effect on purification. Surprisingly, no direct connection was
found between the degree of purification and the vapor pressure of the impurities.
For instance. iron and molybdenum were removod at about the same rate, although their
vapor pressures, at the temperature of rhonium molting, differ by a factor of 1000.
After two or three passes, the rhenium rods became single crystals. Their

TEXT: Pure CaF3 and K9F2 were used as initial materials for the manufac-
ture of the alloys. The fluorides were melted in crucibles made of electrode
graphite. Gas and electric furnaces assuring heating up to 1,3000C were em-
ployed as melting units. The alloy was prepared by previous mixing of powderlike
salts, taken in a given ratio, and subsequent melting of the mixture. Graphite
or graphite-chamotte were the most suitable materials for the manufacture of 0
molds in fluoride casting. In all cases the alloy temperature was 1,060 - 1,120 Q
arA the temperature of the mold prior to casting was 750 - BWOC. Prior to
casting the mold was dried and roasted at 800 - 8500C. The filled molds were

TEXT: The aut.h~,rs pcint 7~ut thal ilte a number of alloys during melting
and pc.urirkg are consideratly contaminated with oxide films which reduce their
1.ectinolcgical &nd mechanical properties and the qua-lity of components. They
enumerate a number of metal, puriflcation proLesses and report on tests which
were carried out to remove films from aluminum alloys by filtration. These
tests were :aLrried ou~ d-aring the sem!-~cntlnuous casting of ingots of the A16
(1)16') andAK6 (AK6) alloys by A,G. Spasskly, M.V. PIkunov and AN. Kurdyumov,
Prior T-, the casting process, filtr8tion was studied by simulating metal fli-
~.ration with water with ptec,?s of paper representing the films. Lumps of
-rusned magnesite bricks were usea as fIlterIng agent. The filtration results
showed that a lump fil,.er -f mm ~nickness holds back 50 - -0% of particles

duction of secondary aluminum to purify the melt from iron. This method
easily removes impurities, i. e. oxide, flux, nlag etc. Filtration is of
particular importance with the casting, of tall molds wheri the velocity of
motion of the metal is hl~,h, particularly (luring the initial stage Decreas-
ed metal veloc;ty in the riser diminishes the darigt:r of 31ag foam, an(', hl - s-
ters. Before filtration the permeability of Ilump filters should be deter-
mined. For this purpose the tests described in this article were curried
out. The time required to filtrate 5 - 7 tons of liquid metal was recorded

1160 537s 19591 119s 570m 1960),, spin-orbital splitting is greater than cryBtal
spUtting.. but according to J. L. Birman (PtWs. Rev.., 114, 149ol 1959),, crystal
splitting is greater than spin-orbital splitting. The author proposes, in line
with previcrus workjo that nesawsments on line displacecents during deforzation
may detarvAm which of the two wdels is valid for a particular crystal and may

to arrive at a determination of tho amount of line splitting resulting from
.definite values of deformation. From this he obtains an expression for the energy
spectrum permitting computation of terms of the equation. Results show that there
can be no doubt that deformation of a crystal definitely causes a change in dia-
tones between lines. By measuring simultaneously the displacement of all three
1~ lines,, it is possible to determine the ratio of changes in ejuwgy levels. By
knowing this ratio In addition to the distance between lines in the undeformed
crystal,, all three constants required for the principal equation my be determined,,
and,, consequently., the proper model my be selected. "In conclusion,, I wish to

!ABSTRACT: This is a continuation of earlier work by one of the
,authors (Aronov, FM v. 5, 552, 1963), where it was shown that meas-
i

t
11determine the effective masses of semiconductor carriers. In this
ipaper it Is shown that measurements of Indirect transitions In crossed

,fields increase appreciably the sensitivity of the method, thus per-
t
!mitting a determination of the structure of bands between which no
idirect transitions were observed, and also to determine the frequen-
icies of the corresponding pbonons. The analysis is carried out.for
'semiconductors in which the extrema. of the valence and conduction
~
,bands are at different points In momentum space. From calculation of
i
'the absorption coefficient and its variation in weak electric fields
ilt is deduced that measurement of the absorption-coefficient variatim
increases the sensitivity of magneto-optical methods for in-
:direct transitions, making it possible to use these methods to deter-
imine the band structure of the semiconductors. It is shown that the
presence of the electric field gives rise to additional measurable
:change In absorption, which increases the sensitivity of the method.
~.!An experiTdent in crossed fields should yield a set of lines corres-
Tonding to different nonequivalent extrema, and measurement of the
;frequencies in-the conduction and the valence bands make it possible
'to determine the components of the effective mass tensor in both
ibands. Expressions For the angular variation of the frequencies were
presented by the authors elsewhere (PTT v. 6, 506, 1964). Authors

ABSTRACT: A brief description is given of a laboratory prototype
of a imass spectrometer with a glags analyLer Provision
is-rde for careful out lassing so that a pressure of about
10 mm Jig or less can be obtained in thp analyzer and
thus ensure the absence of chemically-active gases I . low
residual pressure and the use of a photomultiplier aL the
detector ensured a high sensitivity of the spectrometer
The mass spectrometer was designed for studies in cathode
electronics and the physics of ultrahigh vacuum (outgassing
of oxide cathodes, negative i.on em:Lssion, evaporation of
the cathode material, etc). The basic design was later
used to construct two similar mass spectrometers which are
now satisfactorily working at Kiyev State University and
the Institute of Physics of the Ac.Sc.. Ukrainian SSR. The
working specification of the instrument is as follows
