established the existence of a compound with the composition ScMn03 and
three types of cubic solid solutions; based on S0203, Mn203, and a cubic
modification with the composition Mn304. The compound ScIInO crystalli-
zes in a hegagonal lattice; its specific magnetic susceptibRity is 18.0
t 0.5 x 10- abs. el. units/gram; at 1350 t 2000 it decomposes with the
formation of solid solutions based on S0203 and the cubic modification
Rn304. The solubility of Mn20 in scandium. oxide changes only slightly
with temperature and is from 1~ to 20 mole %; the solubility of Sc20 in
cubic ~~304- rises sharply from 10.5 mole % at 120000 to 30.0 mole ?at
150000. The article demonstrates further that scandium oxide does not
form compounds or a wide range of solid solutions with MnO, NiO, CoO,
OdO, and ZnO. Orig. art. has: 5 figures and 4 tables.

TITLE: A New Automatic Speed Controller for Mine Hoists
PERIODICAL: Ugol' Ukrainy, 1958, Nr 3, pp 34-39
ABSTRACT: An automatic speed controller serves as a controlling link in the
automatic program speed control system and also serves to limit hoisting
speed. The accuracy and reliability of existing speed limiters are inadequate;
the limiters are unfit to operate in automated mining hoists. The controller
compares the actual and set speeds, the latter being recorded magnetically.
A speed deviation brings about a variation in frequency induced in a reading
head. The controller also comprises a self -supervisory device and can be
used for both drum and multirope-friction hoists. Five illustrations.

ABSTRACT: The experimental equipment and research technique have been
described by Vereshchagin (Ref.4). The investigations were
carried out with pure substances of D.I. Mendeleyev's periodic
system and with special steels. For all investigated
substances and steels an increase in resistance to shear, with
increase in pressure, is observed (except for polymorphic
transformation compounds). Comparative data as to the
increase in the resistance to shear with increase in pressure
are shown in the table on p 479 (T25, T50 etc. constant

ABSTRACT: Complete Translation
As already reported by Vereshchagin (Ref.1), the authors
of this paper are carrying out research on the influence of
hydrostatic pressure on the change in resistance to shear
for various substances. Further improvement of the existing
equipment enabled the resistance to shear at pressures of
up to 300 000 kg/cm2 to be studied.
A constant increase in resistance to shear with increase
in pressure can be observed for both the investigated
materials: technically pure iron and high temperature steel

TEXT; Referring to a publication by Vereshchagin and Shapochkin
(scheduled to appear in Zh.fiz.metallov i metallovedeniye) on
measurements of shear stress in pure elements at pressures up
to 50 000 atm, in which certain regularities were revealed,
improvements in apparatus are described which permitted an
extension of the range of measurement to 500 000 atm. A plate
of the metal under investigation is placed between the polished
faces of two truncated cones pressed aga inst each other. The
combination of axial pressure and friction causes the metal plati
to flow in a manner which creates a bi-convex lens shape, whilst
the initially flat faces of the conical pistons become concave.
Two such assemblies are placed in line inside the press and the
middle part between the two specimen metal plates is provided
with means of being rotated about the axis. This creates a

plastic torsional deformation in the specimen, Beyond a
certain axial pressure the deformation takes the form of
internal slipping inside the specimen. The torque was applied
by a rack and pinion mechanism at the rate of I degree/sec an
measured by a piston.-type hydraulic dynamometer. Plates of
3 - 5 mm diameter and various thicknesses between 0.03 and
0.3 mm were used as specimens. Steps were taken to reduce the
contact between the specimen and the conical surface of the
plungers or else to measure the eriror caused by such contact.
Several tests were carried out with each specimen and if the
first of these tests gave singular results, it was ignored.
Thexelation between the torque and angle of rotation was
determined for each value of the pressure applied by the press,
so that the resistance torque to shear deformation was found to
grow with increasing pressure, An example shows the increase
of the torque with pressure for 0.45% carbon steel and another
example the same relation for molybdenum oxide. The latter

of steps in the curve. The evaluation of the shear stressea
from the torque is shown. The presence of hydrostatic support
at the point of contact and the mounting of the plungers in
tapered holes of large steel rings have made it possible to
increase the strength of the plungers made of a stellite-type
material by a factor of 10 (details to be published by

effects of hydrostatic pressures up to 500 000 kg/cm on

of the Bridgman apparatus, described in an earlier paper
(Ref 7) was used. More than 20 elements and 10 steels
and alloys were studied; data on the mechanical
properties of these are entered in Table 1, p 260. The
obtained results are given in Tables 2 and 3 and plotted
in graphs,, Figures I and 2. Most of the substances

of the results indicates that the Shear resistance
increases almost linearly with increasing pressure up to

agreement with previous experimental data and theoretical
calculations carried out by B. Deryagin (Ref 8) about
twenty-fIve yews ago. The calculated coefficients A 1

of the order of hundreds of thousands of kg/cm 2, the
dependence of the shear resistance on the pressure is
more pronounced still. For several substances, the
shear resistance at pressures of several hundred
thousand kg/cm 2 was of the same order as the pressure.
The absolute values are equal or even higher than the
theoretical strength of these substances at atmospheric
pressure. Thus, for armco iron the shear resistance at
300 000 kg/cm 2 was about 750 kg/mm2 and for the steel 45
it was about 1 300 kg/mm 2 (1 500 kg/mm2 accovding to

substances does not permit deriving a quantitative
dependence of the periodic change of the shear resistance
at such high pressures on the atomic number of the element.

ABSTRACT~ The author (with L.F. Vereshchagin has already shown
(Ref 1) that resistance to shear at pressures of some
hundreds of thousands of kg/cm 2 can increase more than
50-fold. He now repo?s the study of this effect for
heat-resisting allo,_ and steels, using equipment available
at the -Institute of High-pressure Physics of the Ac.Sc.,
USSR. The materials tested Tere Nr 1 titanium alloy

tends to rise with increasing pressure. The greatest
effect is shoim by the titanium alloy and the least by
alloy Nr 3; the resistance rises faster for all the
heat-resist-ing alloys than for the iron and type 45 steel.
Above a pressure characteristic for each material the rate
of increase of resistance becomes approximately the same
for all.

TEXT-. Bridgman (Ref.2) and the authors of this Eaper
(Refs.3 and 4) used pressures of up to 5 000 kg/cm in their
experiments in order to study the changes in the friction forces
and internal shear (sliding) at very high pressures and to study
the phenomenon of "freezing" (seizing) of contact surfaces. The
principle of the operation of the test machine used by the
authors of this paper for bringing about shear under the effect
of pressure was described in an earlier paper (Ref-5). A sketch
of the test-rig for applying normal pressure and a torque is
shown in Fig.l. A thin plate of the investigated material is
placed between two carbide pistons and pressed down and, following
that, the pistons are turned relative to each other. The rotation
was proceeded with until the torque stopped increasing, Thereby,

the speed of turning was constant and so small that the thermal
effe.-.ts could be disregarded. The dependence of the turning angle
on the torque for various specific pressures in the normal
direction were determined. Under the effect of the applied normal
pressure the plate assumed the shape of a double concave lens,
whilst the surfaces of the pistons remained convex. The results
are plotted in Figs.2, 3 and 4 and entered in a Table, P.138. The
inp-rease in internal sliding with increasing pressure was measured
up to pressures of 500 000 kg/cmv whilst the increase in the
friction force and the change in the friction coefficient (in 9

higher than those displayed under normal conditions, the permanent

hydrostatic pressure is small, except in cases when the application
of high pressure brings about phase transformations or other
similar changes which may profoundly affect the mechanical properties
of metals. The present authors studied the effect of high

to 1000 kg cm was appiied, the maximum deformation attained
being 55*. The residual effects of both treatments were studied
by hardness and micro-hardness measurements and by metallographic
examination. The results obtained confirmed that no permanent
increase in strength of a metal is attained by the application of
high hydrostatic pressure alone. However, in the case of specimens
subjected to the simultaneous action of pressure and shear,
increase in hardness, reaching 150% in the most heavily deformed
regions, was observed. Acknowledgments are expressed to

TEXT: In their earlier studies of shear under pressure
Bridgeman (Ref.1) and the present author (Ref.2) assumed uniform
distribution of the normal and tangential stresses in the contact

arch,ifit was necessary to verify
th~i's-a-ssumption; hence the investigation described in the present

by a method entailing the use of two axially-loaded, flat-ended
rods made of the carbide 13K (VK), fthe faces of the rods between

amounting to 50 to 100 microns for the contact zone 3 to 4 mm in A

a flat ring at the periphery and a several mm deep hollow in the
centre, were employed. The experiments consisted in placing red
phosphorus between the end-faces of the experimental rods,
subjecting it to both normal and tangential loads, and assessing
the distribution of the loads by the manner in which red phosphorus
changed to its black modification. Red phosphorus was applied
either by painting a very thin layer, in which case the conditions
obtained in direct contact of the hard alloy rods were reproduced,
or spread in the form of a relatively thick layer, in which case
conditions approaching those when a foil specimen is stressed
between the rods were obtained. To facilitate observation of the
effect studied, contact zones of the largest possible diameter-

case of a small degree of concavity (corresponding to loading of
the foil under very high pressures), the.change of colour of
phosphorus took place almost simultaneously at all points of the

the change from red to black started in the flat portion and then
spread gradually towards the centre of the cavity; with
increasing load the pressure distribution became more uniform.
Application of tangential stresses at the moment at which*phosphorus
started to change its colour from red to black owing to the action
of normal pressure brought about a widening of the region of
polymorphic transformation. In order to spread the transformation
over the whole contact area, it was necessary to increase the
torsion moment only by 10 to 20%; as in the case of normal load
applied alone, the change of colour due-to combined action of normal

PERIODICALt Fizika metallov i metallovedeniye, 1961, Vol.12, No.1,

TEXT: Bridgman and Vereshchagin found that with increasing
hydrostatic pressure the shear resistance changes and increases by
6everal times at pressures of the order of 50-100 thousand atm.
In these experiments circular plates were investigated and the
distribution of normal pressures along the areas of contact were
assumed uniform. It was zonsidered that the shape of the epures
of the shear stre3ses is triangular or occupies a position which is
intermediate between the triangular and the rectangular. Since the
real distribution of the normal and the tangential stresses
differ from those assumed in the calculations, a certain error was
introduced. For reducing this error and for evaluating it, the
authors carried out experiments in which the shear strength under
pressure was determined for ring specimens made of commercial iron

L. F. Vereshchagin, Ye. V. Zubova and V. A. Shapochkin (Ref.4a PTE,
1960, 5),For producing high preasurespistons of the carbide BK6 (VK6)
with a ring-shaped face were used. The external diameter of the
ring equalled 10.2 mm, the internal 9.0 mm. The specimens under
investigation were cut from sheet metal 0.04 mm thick. They were
ring-shaped with dimensions corresponding to the dimensions of the
ring area of the piston. During the testag specimens of the
investigated material were plated between pistons on ring-shaped
areas. The loading was in stepsi, when the normal pressure reached
a certain value torque was applied. Turning of one piston relative
to the other was effected until the torque reached its maximum for
the given normal pressure. In th I experiments the magnitude of the
normal pressure was 100 000 kg/cm and of the torque 1000 k&-cm.
The experiments yielded linear relations between the torque and the
axial force, which were the same for commercial iron and niobium.
Since the ratio of the width of the ring to its average diameter
was below 1:10, a uniform distribution of the normal and the
tangential stresses throughout the width of the ring could be

the dependence of the shear strength on the normal pressure was
linear; the value of the shear strength was 15-20% lower than that
obtained earlier for circular specimens without a hole and 40-50%
lower than the values obtained by Bridgman. As a result of the
non-uniform distribution of the normal and tangential stresses on
the circular contact area the measured value of the shear strenith
will be excessively highi at pressures of 50-100 thousand kg/cm
the excess value reached 40-50% in the case of Bridgman and 15-20%
in the experiments carried ouir. at the Institute of High Pressure
Physics AS USSR. L. F. Vereschagin and V. A. Shapochkin
(Ref.58 Inzh.-fiz. zhurnal~ 3, 1960) found that the non-uniformity
in the distribution of the normal stresses along the ava of
contact decreases at pressures exceeding 100 000 kg/cm . This
should lead to a decrease in the error of calculating shear
stresses. There are 2 figures and 5 Soviet references. \All

ABSTRACT: Thin, round plates (diameter 5-10 mm, thickness 0.05-0.1 mm) of Sn, Pb,
Zn, Cd, In and technically Dure iron were tested on a special tester (mean normal
pressures up 100,00o k,g/cm2- temperature range -50 to +2000C, stress sta-e values

i-esults (see Firs. 1, 2 and 3 in the 11-iclosure) were subjected to statistical
evaluation. It was established that the pressure dependence of shear strength
remains linear for Lhe -iven temperature ran,re. Effects of hydrostatic pressure

stren-th decreases in value as pressure rises. The energy parameter, i.e. acti-
vation energy, increases as pressure rises. The function In-e-11T can be assumed
to be linear for a wide temperature range, whether pressure is present or not.
The stren.-th o-4 technical frrades of A was affected directly by temperature (room
temperature to 200C) in the presence of pressure, in that its shear strength in-
