ABSTRACT: .1-i coating steatite ceramics with molybdenum, the layer of ceramics
next to tLe metal changes its properties. X-ray diffraction study shows that,
during the metal-coating, an acid-base interaction between the ceramic
components Si02, B203 and the oxides of Mo takes place. It is assumed that
Si atoms can diffuse preserving their valence bonds; the diffusion is carried
out by a tra.,isformation of these bonds between the atoms. To obtain a strong
coating, Mo should be fired on in a slightly oxidizing medium where Mo is
oxidized to a basic oxide at the ceramic boundary. In this case, the metal--

ABSTRACT: An investigation is made of the conductivity versus tempera-
ture relationships in the 10C 900'3C range of periclase high
refractories of three types, namely, simple magnesite, mag-
nesite with additions, and fused magnesite. The materials
investigated have greater resistivity than P at temperatures of
under 1000c). Refractories of burnt magnesite demonstrate a
semiconductor type of conductivity, while fused magnesite is
dielectric. The samples were metallized by soldering to metal.

ABSTRACT: Paper presented at the Inter-University Conference
on Dielectrics and Semiconductors, Tomsk, February,1958,
In the past much attention has been paid to the physical
and technological properties of the manufacture of
steatite but too little attention has been given to the
microscopic processes, i.e. to structural changes,in
spite of the fact that these changes govern the observed
changes in properties. The main aim of the here described
work was to study the structure and structural changes
of vacuum-tiGht ceramics. The process of forming was
studied of the crystalline component of various steatite
materials which were produced by pressing and also by
Cardl/4 casting under pressure in the hot state. First,the
structural studies are described of specimens produced by

pressing. In studying the ceramic material VK-92 (B)
the lines enumerated in Table 1, P 156, were selecte-a
as being the most charact,eristic for each phase under
consideration. The changes of the phase composition of
this cergic is graphed in Fig.la; it can be seen that
up to 350 C tale predominates, then, due to decomDositior
of the tale, an intermediate product,hydroenstatite,
forms which becomes transformed at more elevated
temperatures into Drotoenstatite; the silica which
separates out during the decomposition manifests 0itself
in the X-ray patterns as christobalite from ~100 0
onwards. Specimens fired above 1250 to 1320 C show a
partial transformation of protoenstatite into 0
clinoenstatite but even specimens fired at 1400 C co-.-. In
magnesium metasilicate, predominantly in the form of
protoenstatite. Magnesium oxide additions between
1 and 6% were tried and also barium oxide additions
as well as additions of oxides of alkali metals
(1% Na20 or K20). In Table 2 an enumeration is given
of the bending strength of specimens from three types of
Card2/4 materials produced by casting under pressure and, for
On thePolymorphism of Steatite Ceramics SOV/139-58-4-22/30
comparison, the data for the same materials are given
if produced by pressing. Some of the results obtained
on specimens produced by casting under Dressure in the
hot state are graphed in Fig.3 and it can be seen that
generally the dependence of the phase composition on the
temperature is comparable for all the tested ceramic
materials. The determined higher mechanical strength of
ceramic materials produced by casting under pressure
is attributed to the absence of polymorphous transforma-
tions of magnesium metasilicate,due to the stabilisation
of protoenstatite and also to the saturation of the glass
phase and possibly also of the crystal phase with silica
which results in an improvement in the physico-chemical
and mechanical properties of the glass phase, which in
turn brings about a stabilisation of the protoenstatite.
The results are summarised thus:
1) It was found that additions of magnesium oxide bring
about a transformation of the protoenstatite into
clinoenstatite, whilst BaO. Na 0 and K 0 brake such
transformation. This is probibly due 2t0 the change in
Card3/4 the composition of the glass phase resulting from the
On the Polymorphisia, of Steatite Ceramics SOV/--,
simultaneous transformation of the silica into the glasS
phase.
2) During firing of cast specimens, a transformation of
clinoenstatite into protoenstatite Was observed C),
The formed protoenstatite has a higher stability to
polymorphism and this can be due to either a partial
dissolution of the christobalite into the glass phase,
which brings about an increase in viscosity, or formation

ABSTRACT: The instrument (Fifr.!) cann be used for raid measurement of
electrical conductivity and Hall's constant for --iven areas on
thin specimens deposited on slides of rl-lass or other dielectric
material. The slide 3 with the deposited samples 4 is kept in
position by the cam 2 on a moveable table 1. The table moves
on a lath along the guide 7. The fixer 5 kleeps the table and,
consequently, also the sample in the require(f positions. A
panel 8 on a moveable table has current, compensation and Hall
electrodes 6 attached to JLt. This panel is kert in -Dlace by
springs 13 and is moved by means of the lever ~ and -cam 10,
perpendicularly to the Plane of the specimen, and keeps the
direction of motion by means of the four rods 12. The elec-
trodes can move freely along the bushes, pressed _i_nto the panel,
under the action of bronze sDri-,)E-:s 11. The scheme Produces the
uardl/3 -necessary control of contact pressure on the sPec-imen and the

panel can be raised when the table 1 carrying the soecimen is
moved. The simple constructior of the electrodes means that one
can have a collection of electrodes eade from different
materials and having contact surfaces of different form and
size, and that one can deposit on their surface various
coatings. When workinft-~ with very thin layers one can put end
pieces of soft metal (e.g. indium or tin )
on the ends of the electrodes to protect the layer. The
distance between the electrodes on the nanel can be varied
deperading on the size of the sample. The samples were deposited
an slides 23 x 80 mm in ar a, the surface area of the samnles
themselves being 23 x 50 mm~
After the deposition, the latter
surface i divided by means of a standard oattern into sections
23 x 4 mm with 6aps of 1 mm between them.- The device is sus-
pended between the poles of an electromagnet on tuwo pivots 14,
connecting the device with a platform placed on the windings
of the electromagnet. Provision is r.,~ade for the control of the
position of the device between the poles of the electromagnet.
The device lies in a gap of 25 mm between the poles of the
electromagnet. Brass was used for the metallic pTts and organic

ABSTRACT: Investigation of the electric conductivity, t1--e thermal
e.m.f. coefficient and t1le Hall constant of t' in layers cf
semi-conductors deposited on a glass base 'n vacuu-- requires
evolviEE special methods of measurement- Frequently, new
ex-oerimental tasks occur, for instance, investi6ation of the
properties of snecimens stored for a L-_)nt, tire in a
vacuum. This task imposes the necessity of ensuring the
possibility of repetition of -',-he measurements at definite
intervals of time, n!aizitainiriL; Lhe a~ubient condiLions con--stant.
The solution of these Droblems is oossible if r;echanicallv-
strong and stable specimens of ohmic contacts are available.
In this paper, a method is described of producinE such con-
tacts for specimens which are then fittea into an ampule 200 mm
.Long, 20 mr. diav,,,ith 6 external leads. The senuence of
Uardl/3 the operations is illustrated by Fig.1, P-115~ It lls based on

cutting off a certain length of the glass ampule, salderiln~, on
tile specimen at the bottom of the leads and then replacinC ti-le
Cut-off part of the glass ampule which is joine(I to 1U1.e OUrier
part of the ampule by applying heat. In t1-_,e case of ti,41'n
layers, deposited on oure glass or on pare quartz, this method
permits ob~ainin- mec~janically-strong and st-able contacts, To
prevent destruction of the thin layer, no solderinj~; flux is
used; the molten indium diffuses through the deposited layer
and forms a strong bond with I.-he base. After soldering- of the
specimen, the cut-off part of the ampule is replaced a~d. joined
on by applying heat (Fig.1, d). The fact that the
and the contacts are at a distance of 12 to 15 cm from the
point of soldering on of the glass prevents their being heated.
Following that, the ampule is evacuated and then sealed. The
ampules also coritain two thermocouples and two platinum leads,
This method was used for investigating the temperature dei~en-
dence of the electric properties of thin layers of AlSb, !nSb
and GaSb deposited by means of tLe method of S.A. Vekshinskiy
on a glass base.

Kazakov, V, A. Candidate of Technical Sciences. Function Generators
Using Diodes 3
The author states that vacuum-tube or semiconductor
diodes may be used in function generator circuits, for
which case errors may be as high as 1 to 3 percent, or as
low as one-tenth of a percent. When selenium or copper
oxide rectifiers are used as diodes, errors will greatly
increase. The author emphasizeaq the advantages of diode-
equipped function generators ovdr electromechanical ones
(potentiometers, rotatable transfo-.:Imers, etc.). These advan-
tages consist primarily in the absence of mechanical parts

and, consequently, in low inertia. The author presents
several schematic diagrams of various types of function
generators and derives their e?uations according to
functions of these generators reproduction of a parabola,
sine and cosine functions, multiplication of two independent
variables, etc.). The author concludes that errors occurring
in the operation of diode furtation generators are mostly
errors of method and instrument errors.

The author investigates the possibilities of developing
drives with position control or with the rate of change
of position or with both methods combined. A powder
magnetic clutch was used as the actuating element. As
setting elements, a potentiometer and a tachogenerator were
used. From these a voltage proportional to the angle and
speed of rotation of the flywheel Is delivered as the input
signal, from which a correspondln~5 clutch velocity is

ABSTRACT: Methodology of the problem of investigating regulating systems in
which a man (operator) takes part is presented. It is pointed out that the ex-
periment should be combined correctly with calculations, that physiological
data of the operator should be taken into consideration, that human reactions
should be expressed as mathematical functions, and that the functions should be
introduced into the system equations. As a result of testing models, it is
pointed out that tracking errors depend materially on the indicator sensitivity
and on the multiplying factor of one revolution of the controller. Sensitivity of
fine reading should be of such value that the fine-reading limit is not lower than

the coarse-reading error. Reduction of the one-revolution multiplier of the
controller is limited by the permissible speed of flywheel rotation. An exper-1-
mental formula is presented for permissible flywheel speed as a function of
the operator's power and the load torque.

A&STRACT:
A self -reproducing machine has been designed at an electronic computer
plant. The Ural-4 was used to work out technological processes for creating
parts identical to those from which it was made. Having obtained the program,
the Ural-4 models the intellectilal activity of a highly qualified technologist.
After about 1.5 minutes, the machine starts to deliver the projected
technological diagram, which contains all the data for making the parts. The
conn,uter reduced the time of preparing the technological documentation by
5-6 times and halved the cost.

TZ%T: The investigation was made with metastable specimens of lead-tin
eutectics on a special machine designed by V. Ya. Shtraus operating with ten-
zion velocities as high as 1.25; 4; 20; 78; ciOlt; and 960 mm/min. The
tests were carried out at 20, 40, 65, 90, 115, 14o, 155, 1065 and 1300C. Maxi-
mum indices of super-ductility attaining 425%; are obtained at 4 mm/min tension
velocity. Elongation approaching this value takes place at 20 mm.1min. At all
the other, higher or lovier, velocities, ductility indices do not exceed 2501%.
At 90SO mm/min tension velocity, maximum elongation is not over 8552. The duc-
tility maximum varies with temperature. At 1.25 mm/min tension velocity, i~ ts
located at about 1750C. At a higher deformation speed (up to 4 mm/min) the

tension of metastable cast eutectics, highest indices of super-ductility are
revealed at a particularly fivorable kinetic correspondence of deformation
and stabilization processes; they decrease when this correspondence J; elimi-

T`EXT: Anomalously high ductility 1,00M,) is observed in Ai-Zn eutec-
toid after quenching from a temperature exceeding that of eutectoid transforma-
tion. This is explained by the course of a diffusion process of stabilization
during deformation. The authors attempted to establish also an anomaly in the
variation of electric resi!~tivity of the Al-Zn eutectoid. Al-Zn alloy specimens
(79~5' Zn) were annealed and quenched at 3200C. -Electric resistivity was measured
after different time of holding at room temperature, The electric resistivity
Of quenched specimens decreased abruptly during the first 8 - 10 minutes afte.r
quenching. After measuring electric resistivity at room temperature, the spe-
cimens were heated wi-Lhin 5 minutes to '2500C. The electric resistIvity of the
quenched and annealed specimens was then equal, and no anomalous effect was ob-

ABSTRACT: The influence of low melting point admixtures, for
in.stance of lead, on0reducing the plasticity of certain
alloys at 500 to 700 C and subsequent sharp increase
at higher temperatures is not dealt with sufficiently
in literature. The changes in the plasticity of brass
was investigated in presence of Fb and Sb for
brasses of the chemical compositions as enumerated in
Table 1, P-53 (about 6W6 Cu, impurities of Fe, Pb and
Sb, rest Zn). The plasticity was defined as the
relative contraction of the cross section of the
specimens during dynamic stretching. The obtained data
as a function of the Pb and Sb contEnts valid for
various temperatures between 20 and 850 C are silmmarised
in Tables 2 and 3, P-53. It was found that durinE the
shaping process contaminated L62 brass should not be
allowed to cool down during the process of deformation
to temperatures corresponding to the temperatures of
brittleness formation, i.e. -that the shaping should be
carried out at hiLter temperatures than for brass with-
out any contaminations. 3 Tables, 8 Russian references.

ABSTRACT: On the basis of literary data and his own results the
author stud-ies the relation between ductility and the
chemical composition of alloys. The "coefficient of
relative alloying", X, is taken as a characteristic of the
chemical composition of solid solutions: X = 100 x C1/Csat.
(C - concentration of the second component in the
solid solution; Csat. - maximum concentration in the
saturated solid solution), X being also a function of
the temperature. The 6raph, Fig.1, gives date on the ductility
of steels with various degrees of alloying as a function of
the temperature on the basis of the data given by Zuyev,M.I.
et alii (8); most of the alloys have high ductility indices
at elevated temperatures and the higher the degree of alloying
with carbon, the greater Is the drop in ductility at tempera-
tures above 0.6 Tfus.abs.' Analogous phenomena are observed
also in the case of m-brass (zinc-copper solid solution),

see Fig.2. Fig.3 shows the change in ductility of copper-
nickel alloys of various degrees of alloying on the basis of
literary data and the results of the author himself and
Fi6.4 shows the same relation for the ductility of certain
nickel alloys. More complex (ternary, quaternary) alloys
show lower ductility than binary ones. Solid solutions
built on the basis of the face centred cubic lattice show a
drop in ductility according to a well defined relationship-
the drop is lowest UL rOO111 telllpOrBtUre, it is soinewhat larger
at 0.85-0-95% Tfus.abs. and largest in the temperature rant;e
0.35-U-85% Tfus.abs.' The obtained results also provide an
explanation for the formation of a zone of brittleness of
brasses in the temperature range 400 to 700 C; this is
attributed to the influence of certain distortions of the
crystal lattice.

ABSTRACT: In the introduction it is said that the results of measurements
carried out -;rlth thermocouples often do not agree, which can mostly
be explained by the fact that the sample and the thermocouple in
the respective case do not possess the same optical properties. For
reasons of the precise definiticn of a nwber of experimental data
concerning aluminum- and zinc alloys, a uniform investigation of
these materials was carried out. For this purpose a differential-
nichrome constantan thermocouple, made of a veire of 0.30 mm thick-
ness, and a round nichrome electric furnace was used. Between the
sample and the heater a nickel screen %ms fitted in orier to attain
uniform heating of the sample. Both soldering seams of the thenno-
couple were fastened in the middle part of the sample by means Of

heating lasting up to 20 minutes no definite equalization of temper-
ature between the sairmle and the thennocouple could be attained, so
that in aluminum alloys differences of 6-8% were observed in re-
sults. A checking of data concerning zinc allo *- showed still higher
results. In the case of the soldered parts being badly fastened to

ABSTRACT: The diffusion of sulphur in nickel was investigated and data con-
cerning the influence of deformation on the diffusion velocity of
the element concerned were collected. The working method is de-
scribed, for which purpose the depth of the layer d, which is
affected by sulphur, served as a measure for diffusion velocity.
The structure observed confirms the opinion of some authors concern-
ing the solubility of sulphur in nickel. From the analysis carried
out it may be concluded that with an increased amount of the
previous cold deformation the diffusion ot sulphur in nickel can be
suppressed. The experimental data obtained by the author are in
contrumft&tion to the opinion expressed in published works con-
cerning the rules governing "a considerable increase of diffusion
velccity in bodies with a distorted lattice,,. The anthor is of the
opinion that the distortion of the lattice exercises influence on
the diffusion velocity, but that in some cases it may also slow
down the diffusion process. (I table and 1 illustration)..

ABSTRACT: Brittleness of nickel parts has been found to be associ-
ated with the -Dresence of sulphur vapour in heat-t-reatment
furnace atmospheres. This effect has been studied by A.K.
Chertaskikh but with insufficient thoroughness, and the authors
present their own experimental results in this article. These
were based on meLallographic investigation of various nickel
specimens exposed to sulphur vapours under various conditions.
The rate of diffusion of sulphur into nickel was fSund to
depend on temperature becoming appreciable at 500 C; the rate
decreases witL increasing degree of preliminary deformation. A
photomicrograph of deformed nickel with a sulphur-saturated
surface layer is shown and graphs of thickness of sulphur-
affected layer vs time and vs degree of deformation ai-e given.
Tables of temperature, annealing time and depth of diffusion and
of changes in composition during annealing in sulphur vapour
