ABSTRACT: The rubbor-motal sealine configuration shown in Fig. 1 on the Enclosure
was inM3tigated, using rubber inserLs with different properties (TH-21 hardness
85-95, 75-85, and 55-65). It was found that the hardness of the rubber insert
played the most important part in securing the sealing effectiveness. Experiments
show6d that hardness was related to tho modulus'of elasticity E60 (after a
60-minute compression) by a single curve for all types of rubber used (E60
F . h]. W"; So = initial area), By pushing the metal ring into the rubber seal
so he - I

Abstract Studied are the magnetic properties of electrons in a metal in the
case of an arbitrary law of dispersion. The authors find the energy
levels of a quasiparticle with arbitrary law of dispersion in a mag-
netic field and calculate the magnetic moment of the gas of such
quasiparticles taking into account spin paramagnetism. It is shown
that the periods and amplitudes of oscillations are determined by
the shape of the Fermi boundary surface. Knowledge of these quan-
tities permit one to reproduce the shape of the Fermi surface and
the values of the velocities on it. Eight references.

Abstract Considered are the magnetic properties of electrons in thin metal
layers in the case of an arbitrary law of dispersion. The authors
determine the energy levels of quasiparticle with arbitrary law of
dispersion in a magnetic field in the presence of a perpendiciDe
potential field. They calculate the oscillating part of the mag-
netic moment of the gas of such quasiparticles, and utilize the gen-
eral formulas for an investigation of the De Haas-Van Alphven effect
in thin layers of metals. It is shown that the periods and ampli-
tudes of oscillations are determined by the shape of the Fermi bound-
ary surface and depend essentially upon the ratio of the thickness
of the layer and the "radius of the classical orbit" of the quasi-
particle. Two references.

The asymptotics of the oscillations of the conductivity in
strong magnetic fields. In this case amplitudes can be
developed asymptotically in a power series. The asympr~otic
is here written down also for' the special case,that FERMI'S

The oscillations of the resistance: When experiments.are

Thereiore the oscillatory share of IR CIA has to be determined.
The connection between CrCIO and RaO is given here. The
expression for A Q N3 contains classical values and oscil-

concrete cases are computed (one zone of conductivity and

ABSTRACT: In the course of recent years a number of experimental papers
has been published which deal with the influence exercised by
elastic deformation in metals on certain physical phenomena
which are connected with the character of the energy spectrum
of the conductive electrons (Refs 1 - 4). Proceeding from the
semiphenomenological calculation of the influence exercised
by an elastic deformation upon the electron spectrum, the
present paper investigates several effects ocr-=ing in the de-
formation of metals. Investigations are based on the assump-
tion that the influence exercised by elastic deformation upon
dispersion can be taken into account in form of a small ad-
mixture to the electron energy in the undeformed metal

ABSTRACT; In a previous paper (Ref 1) the author already spoke about in-
v,.-stigat ions carried out of the de 11aas - van Alphen (de Gaaz -
van AlIfen) effect in alowly varying inagnetic fields and in-
vestigated the question as to when it is possible to proceed
from formulae for the quantization of the motion of electrons;
together with Lifshits (Ref 2) the magnetic moment of the elec-
tron gas in homogeneous magnetic fields was calculated. In the
present paper the author investigates the quantization equa-
tiono in an inhomogeneous magnetic field the gradient of which
is vertical to the direction of the field, as well as the part
played by the inhomogeneity of the field when the de Haas - van
Alphen effect is dealt with by means of the impulse method. The
author bases an the assumption that for particles with the

pp 251; - 267 (USSR)
ABSTRACT: Recently, several experimental researches have appeared
devoted to the change in shape of solid specimens in
allotiropic transformation. The multiplicity of factors
controlling the effects has made theoretical treatment
difficult. The present authors attempt to evaluate the
defor-mation of a flat solid specimen on the basis of a
purely macroscopic examination of mechanical stresses
and deformations due to changes in the specific volume.
They formulte conditions in terms of an isotropic
solid. 1,ayer, assuming temperature stresses are comparatively
insignificant, Figure 1 showing the arrangemeat of the
phaso boundaries. The boundary conditions are determined
and general equations deduced. Deformation and dis-
Cardl/2 placements are analysed on the basis of the equations

Deformation of a Flat Specimen of a Solid in Phase Transformations
deduced. The authors next consider residual deformations
and stresses in the specimens; Figure 2 shows the
relation of the stress and deformation in the new phase.
After it discussion of residual deformations and stresses
in the reverse phase transformation, the authors go on
to exeunine phase transformations with large specific-
value changes. Figure .9 shows the relation of stress on
deformation. There are 4 fiZuk-es and 4 Sovlet references.

Inelastic deformation and residual strains of a
flat solid layer under polymorphic transformation
PERIODICAL: Ukr&7inslkyy fizychnyy zhurnal, v. 5, no. 4, 1960,
479_485
TEXT- An infinite isotropic layer is considered which has two
phases (I and II) with different physical properties (in particular,X
xqith different specific volumes, whereby 6V/V = 36o). If the sur-
face temperature of the phase-I layer reaches the value of poly-
morphic-transformation temperature (transition from solid phase I
to solid phase 11) or exceeds it, then the phase-II layer is formed.
Assuming that at the phase boundary the infinitely thin, defonned,
phase-I layer passes into phase-II which remains attached to the
phase-I layer, then, owing to the different specific volumes of the
phases, a stress-strain state of the specimen as a whole arrises;

this state changes with time in accordance with phase-boundary dis-
placements. The case is investigated when the relative change in
volume of the body due to phase transformation exceeds the deforma-
tions corresponding to the elastic-limits of the phases. Such a
problem is encountered in considering mechanical processes in solids
which take place at cyclical temperature regimes, the surface tem-
perature passing repeatedly through the polymorphic-transformation
point. The problem was dealt with, where the observed effect was
entirely due'to plastic deformations, while neglecting relaxation
stresses, by two of the authors (Ref. 2: A.M. Kosevych L.V. Tana-
tarov, Fizika metallov i metallovedeniye, 8, 225, 19595. In the
present article, the relaxation processes are taken into account.
The hysteresis character of the plastic deformations, as well as
the relaxation stresses, lead to residual strains in the specimen
(after it passed into the new phase). These residual strains cause
irreversible changes in shape of the specimen. The principal ass-
umptions and equations are similar (in the present article) with
those of Ref. 2 (Op. cit), but the~results differ substantially,
Card 2/6

since the relaxation stresses involve the dependence of the resid-
ual strains on the rate of motion of the boundary phases, i.e. on
the heating and coo-ling, temperatures. Two cases are considered:
a) the relaxation time -V is large as compared to the phase transi-
tion time T; b) 'r is smaller than 2T. Case a) A system of differ-
ential equations is set up for the stress tensor a. These equa-
ti'ons are solved by the method of successive approximations, after
expanding iu terms of the small parameter Tft. The residual strain
is given, in the first approximation, by

TEXTi A local melt means the melting of a small spot of a solid body
which appears if in a small spot of the body a certain quantity of
heat becomes free veiry quidkly. The authors consider the plastical
deformation caused by the difference of the specific volumes of the
solid and the fluid state of aggregation. It is shown that during the
hardening of the melted spot in the fluid there may appear a very high
negative pressure which may involve a rupture of the fluid and finally
an appearance of c&vities in the hardened body. Here it is assumed that
the heat beoomes free instantaneously, that the body initially was
isotropic, that the apecific volume of tho fluid state of aggregation
is greater than that of the solid one, that the relative enlargement

easily satisfied at the same time for metals at low temperatures. The

The method described here for expanding the kinetic coefficients in a

reasons of simplicity, however, an isotropic quadratic diSDersion law is
assumed here. It is found that the oscillating part of the coefficient

phase transition is solid 1 -4 solid 2, their specific volumes dif-
fering from each other.The auV_orB show that the equations descri-
bing the deformation of the cylinder are formally identical to
those derived fjr the case of flat plate in (Ref. 1: Fizika metal-
lov i metallovedenlyep 1959t 89 po 255). If the surface temperatu-
re of the cylinder is equal or higher than the traneition tempera-
ture, the boundary moves inwards and can be represented by a cy-
lindrical surface. The velocity of the boundary is assr-med to be
known and meshanical stresses and strains are considered. The func-

TITLE: Dislocation theory of hysteresis effects during tivinning and
shearing iii an unbounded medium
PERIODICAL: Pizika tverdogo tela, v. 3, no. 11, 1961, 3263 - 3271
TEXT:- The author considers the,hysteresis effects which occur during
twinning and shear formation in an infinite crystal. The crystal is
assumed to be exposed to an external stress which changes infinitely
slowly but monotonically with time. A very simple isotropic model with
equilibrium dislocation distribution is chosen. First the two-dimensional
problem of twin formation under the action of an external monotonically
growing stress in consi&red. The trace-of the axis of the dislocation
source coincides 'with the beginning of the planes of Cartesian coordinates
