ABSTRACT: The authors established a correspondence between the dialoc&+Aon theory
of fine twins and the phenomenological theory proposed by I. M. Lifshits (ZETF, 18,1
11M, 1948). They hFive investigated the actual physical sense, the microscopic
nature, of a number of parrmeters involved in the mrcroscopic theory. These param-
eters are complex, involving, surface stresses acting on dis~qcationq, twinning
angle, deformption ratio in trinned and untvinned crystals Ohnd related factors that
do not permit easy plZrsica-l representation. The auTtors ve found t1m form of

ABSTRACT: In view of the lack oJ! a consistent theory of deceleration of
dislocations, brought about by the discrete structure of the cryBtal in
which the dislocation moves, the authors consider the deceleration of a
moving linear dislocation in a continuous medium, resulting froin macro-
scopic processes of dissipation of elastic energy. The method used is
similar to the electrodynainic calculation of ionization losses of charge
particles passing through a mediinn. The problem is solved in first ap-
proximation for a linear dislocation moving with constant velocity in a

TOPIC TAGS: crystal dis ocation, atom, flow velocity, diffusion mechanism
ABSTRACT: Diffusion mechanism has been analyzed for a crystal flow in which the
sources and sinks of point defects (vacancies and interstitial atoms) are prismatic
dislocation loops within the crystal grain. A unixial external load creates condi-
tions leading to the appearance of diffusion flows which transport the substance
from one dislocation loop to another. It was shown that the flows may produce a
stationary state in the crystal which is characterized by a constant rate of plastic
deformation. If the number of creatioit centers of the dislocation loops is not very
large, the rate of flow of the material, should be proportional to the cross section
area of the crystal grain and to thivolume density of the creation centers. Under
certain conditions, the flow velocity increases linearly with the growth of the

external load. Generally, the dependence of the flow velocity on the external load
is determined by the nature of distrib~ition of the dislqaDion-formation centers.

successive rapid heating and cooling of the specimen produces stresses in the metal. Two
factors are taken int10 account: the hysteresiEi character of the equations of the phenomenolo-
gical theory of plasticity and the relaxation ol elastic stresses. Owing to either of these.factors
the shape of the specimen following the cyclia heating-cooling process differs from its original
shape, i. e. residual deformations appear. It is shown that the pulsed heating of the rod at
which the max-imum temperature suffices for the development of plastic deformation causes the
rod to undergo irreversible plastic changes. rho residual deformations are proportional fri the
change in temperature mid affected by the relmtionship between stresses and elasto-plasvc
deformations. Orig. art. has: 36 formulas.

the creation of an elastic'-twin., but differs fromIthe twinning process in ionic

ABSTRACT: It has been earlier established that an amorphous phase
occurs in thin films of antimony. Two transformations
a- and 0- were distinguished when these layers crystal-
lised. Here the crystallisation of amorphous layers of
antimony, evaporated onto amorphous substrata (quartz or
collodion) is examined. Observations were made of the
electrical resistance and also metallographically and
electronogra~hically. Films were condensed at
8 x 10-7 g/cm2sec. Initially, the Sb appears ches'tnut
and then develops blue spots, the latter (as shown
electronographically) being a crystalline phase. This
is-the a-transition. A graph of the dependence of the
time for full transition to the crystalline state on the
thickness of the lkyer is given. h a is the thickness

one minute. The tizo of condensation of the film t is
given by t - dh/w 0-0?4 h secs (d is the density of
2
Sb and w = 8 x 10_~ g/cM see the rate of condensation).
The rate of growth of crystalline spherulites in an
amorphous layer as a function of its thickness was
measured microscopically. The stability of the Sb as an
amorphous thin film can be explained if it is regarded
as a super-cooled liquid with a co-ordination number of 3.
On the sudden cooling, a compression of the film arises
but at a temperature below that of crystallisation, bonds
with the substrate a:~e established and the substrate is
compressed. The resulting tension std-Dilises the
amorphous phase. This tension decreases in the Sb as the
thickness increases. Amorp ous phases are known in other
metals for layers of 30-50 ~ (00, V, Or Be) but here the
thickness of a stable layer can be 270 k . Using
diffraction methods, a diagram of the a- and 0-

ABSTRACT: On the basis of the method worked out by S.A.VekshinskV(Ref 1),
the following method was worked out for electronogrophic investi-
gation. In pr4noiple it consists in the fact that on a horizontal
plate (the collector), which is divided into three surface'.sections
by means of two vertical plates, the metal vapors emerging from
the test crucibles are collected. outside of the two separating
plates the pure metal condensates, whereaz between them the alloy
is separated. For the purpo3e of calculating the concentration of
the alloy two methods can be applied: Firstly, the method of sym-
metric lines, and, secondly, the method based upon the radius. For
the control of the arrangement of the separating plates the photo-

ABSTRACT: Metallic layers of various thickness were investigated which
had been evaporated on various bases in a vacuum. The thick-
ness of the layers was measured by a microinterferometer
according to Linnik, while the microhardness was determined

with two special devices by the mechanic V. V. Gordienko:
an automatic load mechanism,, and a coordinate table which
makes possible the observation of the exact position of the
investigated point at the colleotor in polar coordinates.
The apparatus was standardized by means of rock salt; the
selection of the metals to be investigated was made in such
a way that various combinations occurred: soft layer-hard
basis, hard layer-soft basis. The results obtained are given

Graphical representations with the corresponding explanations
are given. From the results obtained may be seen that with
soft layers on hard bases the value for n is lower than for
hard layers on soft bases which must be taken into account
in the determination of the microhaxdness of various coat-
ings; besides it was observea that the value n is greater
with small load. Therefore the microhardness can be determin.-
ad at the samples obtained according to the method by S. A.
Vekshinskiy (Ref 4); the thickness of the sample should be
10 p and the material of the bases should be harder than
that to be investigated. There are 2 figures, 2 tablesy and

ABSTRACT: In the present paper the kinetics of the cx- and ~-transfor-
mations in Sb films which at room temperature were condensed
on amorphous (glass, collodion) and ciystalline supports (ion
salts, metals) is investigated. By means of metallographic
and electronographic methods and by the method of measuring
the electric resistance the authors first constracted the dia-
gram of the a-transformation in Sb-films which were condensed
on glues or collodion. This diagram determines the duration of
the transition of Sb-films from the amorphous state into the
crystalline one as a function of jhe thickness of the film. in

formation and the macro-structure of the crystalline antimony
are qualitatively different in the case of a- and P-trans-
formations. The a-transformation is a diffusion transformation
with regard to its kinetic characteristics and to the struc-
ture of the forming crystalline phase. The P-transformation to
a certain denree resembles the known diffusionless martensite
transformations. There is also sense in the expression I'dif-

crystalline phase of Sb takes.place without preferred
orientation. All orystalline substrata lead to a decrease
in the critical thickness of an amorphous layer of Sb by
30-50016. Those of group (b), besides this, decrease the
the stability of amorphous Sb. Metallic films, not
covered by oxide layers decrease the stability of t e
amorphous phase of Sb most markedly. Substrata having
non-metallic bonds or those covered by passivising layers
behave towards the Sb as if amorpohous. Investigation
of the orientation of textured 3b condensed on metal
films shows that the orientational correspondence between
crystallites of Sb and the metal is established indepen-
dently of differences in the geometry of the crystal
lattices,, The basic conditions affecting the orientational
correspondence consists of the adjacent layers having the
same (in this case, metallic) bond type. Moreover, there
must be direct contact between the layers.

arbitrary angle with the twinning planev and shows that the
critical characteristic of such a barrier (inclusion) is

ABSTRACT:
f'ardl/2
A concontrated loaid was used to give a quantitative
estimate of twinning in monocrystals of bismuth, antimony,
and b�simuth-based alloys. The loadIng used was a
microhardness tester PMT-3 with a diamond pyramid.. The
type of impression obtained is shown in Figure 1. It is
shown that the length of the twinned band (1) and the
diagonal of the impression (d) are related by the
equation t =. a + ad (Figure 2b, 4). The coefficient a
can be used as a quantitative estimate of the intensity of
twinning of a givon crystal. With homogeneous bismuth-
antimony alloys, the value of a markedly increases with
increase in antimony content. The increase is similar
to that for microhardness. Figure 5 shows cx (continuous
line) and hardness (dotted line) against antimony content.

TITLE: Formation of dislocations in the electrical erosion of
single crystals
PERIODICAL: Doklady Akademii nauk SSSR, v, 138, no. 1, 1961, 96-99
TEXT: The authors have examined the distribution of dislocations produced
by spark discharges on bismuth, antimony, and zinc single crystals. For
bismuth and antimony the experiments were performed on the (111) cleavage
planes, and for zinc on the (0001) plane. Thu following etching agents
were used: for bismuth 20 % of HNO 3 in CH3COOH, for zinc 7 % of HC1 in
CH3COOK, and for antimony, CP-4 (SR-4)- Prior to the experiments, the
specimens were examined for dislocations, whereupon.those sections of the
planes concerned that contained the least dislocations were once subjected
to a spark discharge. The sections were then photographed (Fig. 1a) and
etched again (Fig. 1b). Besides anode and cathode holes, it vas thus
possible to establish a major number of etching figures giving evidence of

an intensive formation of novel dislocations. The density distributions
of dislocations are graphically represented in Fig. 2 for anode holes.
As may be seen, the large dislocation densities ( >10 6cm-2) do not reach
to a depth beyond 25 A. In the range of 25 -100 ji the densities amount
6 _ -2 are rapidly reduced to
to about 1-10 5-105 cm , and at greater depths L
normal density. Fig. 3 presents a zone,diagram cl the density distribution,
conetrubted on the basis of the abovementioned results. The density
distribution of dislocations around cathode holes differs considerably, in
bismuth and antimony, from that in case of anode holes. Here, ine etch
patterns form an inner dark ring'-shaped zone, and an outer brighter one
(Fig. 4a). One may see-from greater magnifications that those of the inner
dark zone are deep, sharp etch patterns, while those of the outer zone have
a flat and smooth character. The new dislocations on the zinc specimens
fill a hexagonal plane both in caae of anode and cathode holes (Fig. 4b).
Dislocations in these experiments are the result of the following physical
processes: 1) The surface meete an air shook wave arising in the discharge
space. 2) Crystal undergoes a melting anO solidification process. 3) A
field of thermal stresses is formcd. The air shook wave merely leads to a
formation of dislocations on the aipeoimen surfa.oe. Melting of the crystal

ABSTRACT: Rapid heating and coolting of the electrode due to a spark discharge produce
a number of defects in the crystal structure of the metal. These are of interest in the
study of mechwifisms of electrical erosion. In the present paper, the dislocation effects
in monocrystals of bismuth, antimo,ay, and tin were studied by selective depth etching
and microphotography, while the Inerease in lattice vacancies and the lattice packing
defects in polycrystals of gold, silvar, and copper were studied by means of X-ray

techniques. In the dislocation study, the crystal surface was initially etched, then sub-
jected to a spark discharge, and theri etched again at selective depths to expose lkyers of
various dislocation densities. The resulting dislocation density curves for bismuth
(anode trace) are shown in Mg. I and the corresponding density depth profile is shown in
Fig. 2 of the Enclosure. The cathode trace density distribution is shown In Fig. 3 of the
Enclosure. Three distinct physical mechanisms present in the electric spark discharge
explain the shape of the above density curves. The air shook wave contributes heavily to
the creation of dislocations in thin surface layers 'and is' pronounced in the cathWe trace
(segment nl1p in Fig. 3). The point hardening due to local crystal melting is prominent
in the rnode trace (segment abc in Curve I of Fig. 1) at the surlace. The impulse field
of thermal potential is by far the largesk contributor to the dislocation effect in volume
(segment k1m in Fig. 3, segment db1l of curve I and curves M - VH in Fig. 1) and is
more pronounced in the anode trace. Thit, is explained by the fact that the time duration
-of the thermal potential wave in the anode is much longer, due to local melting. The
'packing and vacancy defects were investigated using 9.99% pure polycrystallinc copper,
silver, and gold. The changes in lattice parameters after the spark discharge were ob-
served by comparing Wtial and final X-ray spectra using cobalt radiation with the
following standardst silver for gold and copper and iron for silavar. 7ho Una (420) was
used for calculations. 7be decrease in the lattice parameter IV after spark discharge

It was found that thq parameter "a!' decreases due to 'a spark discharge effect. This
decrease was found to be different for different lines, as shown in Fig. 4 of the Enclosure,
from which the W- stence of packing defects in the crystal lattice is evident, since the
distances between atoms in various lines can either increase or decrease (decrease for
line 331). Tbe-concentration of this defect was calculated to be of the order of 1%. The
parameter "all tends to return to its initial value, the return rate being faster when a
high-temperature annealing process is used (6 minutes at 300C which fully corresponds to
the annealing time for hardened vacancies). The packing defects having higher thermal
stability require higher annealing temperatures for a = a42 - to chleve its normal

value (600C for 20 min.). Such unusually high concentrations vacancies (0. 29%to 0. 40%)
have not previously been observed and are attributed to rapid heating and cooling of metal
when subjected to a spark discharge.- Origi art. has: 8 figures, I table and I formula.

STRACT: The published data on the phmse composition of Co films obtained by vacuum
condensation are highly contradictory; this is apparently associated witli the non-aniformity
I of experimental conditions. Accordingly, the authors performed a systematic investigation of
the phase composition of these films as a function of the chief parameters determining the
manner ofgrowt1i of the condensates: 1) substrate temperature T.; 2) condensation rate w;
3) degree of vacuum; 4) effective film thielmess h. 99.98% pure Co was condensed on carbon
