Theauthors give a report on investigations of deformation
processes in rock salt in the case of the formation of ele-
mentary displacements constituting a special deformation state
(further deformation leads t-o the formation of individual gliding
bands). The following stages are distinguished: Elastic defor-
mation (d -100);
isotropic light scatter (Tyndall cone) (d > 120); as terism (tf > 600);
destruction(6 >2000). The d-values give the normal tension in
g/MM2. The aG tivation energy reqtLired f or annealing the residual

traces of the elementary displacements. It is suggeoted that
this is due to the effect of the line inhomogeneities which
are differently orientated on both sides of each trace. Some
traces of elementary displacements have been found to coatract
after the load is removed as in the Case of elastic twins of
sodium salpetero The trace of the elementary displacement on
the lateral surface of the crystal was found to have a amooth
profile extending over 1500 2. This smooth profile can b9
satisfactorily explained by the effect of the surface tension
forces which are in thermodynamic equilibrium with the additional

TEXT: The low strength of solid bodies after deformation is.ascribed to
dislocations, fractures, and microcracks and the resulting concentratioA
of strains which attain the value,.of theoretical strength in microregions.
Furthermore, the formatioN splittingp and disorientation of microblocks are
observable. The concentration of strains may be regarded as an increase in
~latent energy which is due to the extension of the inner surface brought
about by disorientation. The surface energy of the liberated parts of the
block surfaces would pass over into latent energy. The block dimensions
themselves have a specific value for every material. According to B'. M. Ro-
vinskiy and L. M. Rybakova (Ref. 7), this value constitutes a mean value of
split and restored blocks. In this 'connection, the saturation of the latent
deformation energy corresponds to the stabilization of the mean block

TITLE: Welding, opper by Exposure to Sonic Vibrations
PERIODICAL: Fizika metallov 1 11,11 tallovedelliye , 1960, Vol.;O' 9100.11,
TEXTs Investigations were carried out using an oscillator,
a magnetostriction device, an arrangement for loading and a vacuum
chamber. The apparatus is shown in,Fig.l. The specimens were
simultaneously loaded with static and dynamic ressures. The
experimentswere carried out in a vacuum'of 10-3 mm mercury. The
influence of the applied pressure, the temperature, the time and
regime of vibrations on the strength of the joint were investigated.
The samples were heated by a molybdenum,heater and shields of thin
..sheets of stainless steel. The samples were prepared from
oxygen-free copper in the form of a disc, 16 mm in diameter and
10 mm hi h (Fig.2)~. The strength of the joints was tested on an
lvim_4p NM-4R) machine. The optimum time of exposure to sonic
il;;vlbrations in order to produce the strongest joint is 20 to
30 seconds at 825% and a pressure of 1.5 kg/mm2 (curve 1, Fig-3)
and 2 to 3 minutes at 700 C and a pressure of 2.5 kg/mm2 (curve 1,

treatment after the sonic treatment at the same temperature.
Curves 2 in Figs-3 and 4 show the strength of joint without the
sonic vibrations. To obtain joints of similar strength to those
obtained with vibrations, the pressure has to be maintained for one
hour at 8250C or three hours at 700*C without the application of
vibrations. Thus the time is considerably reduced by the use of
.the vibrations. Fig.6 shows the microstructure of a specimen
after 4 minutes application of vibrations at 6000C (the optimum ti e

that of the original material. The strength of this sample was

19 kg/mm After 20 minutes vibration, the grain size becomes
coarser and cracks begin to develop (Figs.7,8). The strength fell
to l4to 15 kg/mm2. Fig.9 shows a sample after 10 minutes
vibration at 825*C. Cracks have developed in the grain boundaries
of the coarse grains., Fig.10 shows the relation between the
strength of the joint and static pressure at 6000C, Curve 1 is

reduced to obtain the same strength. The use of vibrations also
enables joints to be obtained with low values of plastic deformation

TEXT: The present paper is a continuation of Ref. 13 (Geguzin and V ' I
Startsev, Kristallografiya, ~, 2, 1960) and brings results of an experi-
mental and theoretical investigation which has been performed to study
the influence of uniform -oressure on the healing of defects (coalescence
of pores and micro-cracks) occurring during plastic deformation of NaCl-
.crystals. Samples 0measuring 5 * 6 - 15 mm (natural rock salt) have
been heated to 650 C for two days and after that cooled down slowly.
Samples without any defects have been selected for the test. In order
toproduce micro-defects (of one magnitude smaller than the wavelength of
visible light) in these samples they have been deformed with an exponential-
ly increasing load. An increase of light scattering could be observed

tween 1250 and 1350 g/mM2. Then, the deSormed samples have been exposed
to heat treatment in an autoclave (60 cm ) under uniform pressure (argon).
After this, the light scattering has been studied at room temperature
using an ultramicroscope. Several test series have been performed, in
order to obtain useful results (isothermal treatment at 400, 500, 6009
and 7000C at 1-50 atm, during T - 30 min). The results are shown in
Fig. 1: i = (i o-ib)/(in- ib) as function of pressure at four different
temperatures; where 1 0 is the intensity of the light scattered in the
crystal, i n is that after crystal deformation, i b is the intensity of
the background. The time dependence 0(T) of the lighttransmittance of a
crystal at p - const, T - const (500 C, 1, 30, and 70 atm) has been
investigatedin another teat eeries. The reoults are 8hown in 0Fig. 2.
The temperature dependence i(t) at a constant h8ating rate (10 /min)
has been studied also for 1 and 30 atm. At 100 C a noticeable healing
process can be observed. The results may be interpreted in terms of the
diffusion theory. At given test conditions and a given value of the

The process studied by the present authors consisted in butt-
joining two flat, ring-shaped aluminium specimens by simultaneous
application of heat and pressure and constituted, in facto pressured
welding. The object of the present investigation was to study the
relationship between the strength of joints, produced by this
methodq and the pressure employed, temperature, and duration of the
process. In addition, the variation of the microstructure near the
joint interface was studied, and the temperature dependence of
hardness of aluminium was determined, To minimize the effect of
oxide films and gases absorbed on the metal surface all
experiments were carried out in vacuum of io-5 to 1;-6 mm Hg.

Investigation of the process of sintering metals. Ii.
Immediately before each oxperimento the surfaces to be joined were
cleaned with a steel brush after which the surface roughness was
0.5-1.5 1&. The two rings were then assembled in a specially
designed press, the whole was placed in the vacuum changer.~ the
temperature of the aluminium rings was raised to 6oo IC and kept
constant for 15-20 minutes, after which they were cooled to the Vx
test temperature and the appropriate load applied. The strength
of the joint was determined on a tensile testing machine. The
results are reproduced graphically. In Fig.4, U.T.S. (Op, kg/mm2)
of the joint obtained under 'pressure P = 0.32 kg/mm2, is plotted
,against the sintering time-(T, minutes), curves 1-4 relating to
sintering at 450, 500, 550 and 600 OC respectively. A similar set
of curves, constructed for joints obtained under p -- 2 kg/mm2l
is reproduced in Fig.5. in Fig.6, ap is plotted against p
.(kg/mm2), curves 1-6 relating to joints obtained at 300, 400, 450,

results that the process studied takes place in two stages. The
firststaSe consists in the formation of metallic bond between the

clean surfaces brought into intimate contact by the action of the
applied pressure. The strength of the resultant joint is deter-
mined mainly by the conditions obta-Ining during this initial stage.
It in pointed out here that for the joint to be formed, it is not
only%necessary to bring the two mating surfaces within a distance
equal to the lattice parameter of the metalo but a re-grouping of
the atoms has also to take place in order to create conditions
favourable for-the formation of the metallic bond. The activation
energy for the re-grouping of atoms in aluminium has been found to
be 6.4 kcal/mol. In the second stage of the process, in which
diffusion plays the predominant partg the areas of contact
established during the first stage increase as a result oft
(1) movement of vacancies to the boundaries of the welded regions;
(2) coalescence of the excess vacancies and formation of large
pore a due to dissolution of small pores; and (3) dissolution of
large pores. The effect of the second stage of the process on the
strength of the resultant joints becomes significant only at high
temperatures and after a prolonged sintering.

TITLE# Method of determining the tangential stresses in a medium
under high pressure,
PKRIODIGALt Fiiika tverdogo tela, v. 4, no. 3, 1962, 810-811
TEXT: A method of.determining tangential stresses in a solid compressed
by solids is described. It is based on determining these atreases for
standard single crystals which at relatively low tangential stress show
traces of residual deformation. From the stress - strain diagrams a
standards compressed under hydrostatic conditions one can then find the
tangential stresses in any specific case by determining the difference
between the hydrostatic traces and those obtained by compression between
solid's. -Bythis method.it is also possible to determine the solidifica-
tion point ofla liquid. There are I figure and I table. 'The-English--

The-device (see Fig. 1)
contains a casing with two liquid-filled inter-
connecting cylindrical chambers, and two plungers rigidly connected together and
moving within the -above chambers. One of the plungers t ,ransmits'the load to the
sample mounted between the plungers, while the other compensates for the change in
volume caused by displacement of the -first plunger. To improve precision, meas-
urement sensitivity, and automatic' recording of diagrams reflecting changes in
sample volume,due to.deformation, the pluager resembles a ---tgid cup with the sample

:ABSTRACT: -Experiments were made on the sintering ?f technically pure iron samoles.!
,Wm at 525-1060G-,pressures of
ISintering was crried out in a vacuum 1.33-0.131K
1.0-607.6 M,Wm~ and time intervals from 3 minutes to 10 hours, The relation
the consolidation strength to temperature, pressure afid sintering time was
~detcrmined, and the relation of the beginning of setting to crystallographic grain
orientation roughness of grain surface, and the presence of scales on the surface
ihave been studied. It was established that the increases in pressure, temperature,
;and sintering time increase the strength of the product, The inicroroughness
the fragment surfaces prevented a simultaneous contact along the whole contact-
J !surface. , The contact was achieved subsequently by a further increase in pressure
to level the rough places. An increase in strength is possible because of the
diffusive growth of contact areas due to creep, coalescence, and closing of voids

:between the coalescing surfacesi This is achieved by increasing temperatures
.,and sintering times. Durable bonds were obtained by a close contact between the
particle surfaces and by nondiffusive local rearrangements of.the crystal lattices
~on the contact surfaces The activation energy of atomic dibplacement during rear-
rangement was 35-1 kjImol., considerably smaller than the activation energy of iron
diffusion. "The authors express their appreciation to R. 1 Garber and V. S. Kogan,

ABSTRACT: In an article -in "Tavatnyye Metally"I 19'6, No.11 by
I. N. Plaskin,.A. M. Okolovich, V. V, Shikhovaya-
N6ginikaya and G. M. Dmitriyeva some problems in the develop-
ment of a scheme for the flotation of polymetallic ore were
formulated and proposed for discussion. The present
article contains discussions of theae and additional
problems, based mainly on experience at the Belousovsk
beneficiation works. The quality of the ore (Pb 4 1%)
there has recently been cWmging and a two-stage ore
grinding process has been adopted; while research is
proceeding on the corresponding two-stage flotation of the
lead sulphide, which is especially important at this works
because of the extensive.adoption of direct successive
flotation'there. . A qualitative flow-sheet for two-stage
flotation is shown and discussed, different variants being
1/2 compared. Agreeing with the contention of Plaskin et al.
that it is very difficult to obtain with tWO-Btage flotation.t

TITLE: New Mass-Production Radio Receivers (Novyye massovy-ye
radiopri~,eumiki)
PERIODICAL: Radio, 1959, Nr 4, pp 12 - 15 (USSR)
ABSTRACT: The Soviet radio industry has begun the mass-product-
ion of the "Zarya" and the "Strela" radio receivers.
Although the same types of miniature tubes are used
in both, their circuitry is different. Figure 1
shows the circuit diagram of the "Zarya" and Figure 2
that of the "Strela" receiver. They are designed for
reception of radio stations working on medium (187-
577) and long (723-2000)-waves. They may be connected
to any type of record player. The sensitivity of
these receivers at an output of not less than 0.5 watts
and a sound pressure of 3-3.5 bar, is not less than
400 microvolts. The range of reproducible sound fre-
'.Card 1/2 quencies is from 150 to 5000 cps at a non-linear
