Issued: 11 / 1957
The first report (B.JA PINES, N I,SUCHININ, Zurn techn fis,26, 7 (1956)) showed
that the mechanic strength of porous "metallic ceramic" eam;-les (obtained by
pressing and annealing metal powders at one and the same temperature) depends
linearly on porosity
The present work describes breaking strength tests oarried out at temperatures
of up to 9000 C in a R2 atmosphere with samples of -,ompressed powder which had
previously been annealed for different length& of time at a temperature of
10000 G. On thle occasion load velocity was modified by 100 time 110its original
amount. For samples of equal porosity which were tested at - 900 C the linear
connection between the logarithm of load velocity and the value 2)r strength re-
sulting from the dependence of "life" on itress wae -,onfirmed
Samples with different porosity show a linear decrease of the strength p with a
growing poro 11 ity ~ also when tested at high temperatures (with load velocity re-
maining constant), so that it is possible to determine the value for strength
which is extrapolated for a growing porosity The aforementioned linear connection

ABSTRACT: The determination of the dependency of concentration of the dif-
fusion coefficient D necessitates tho explanation of the tintribution of con-
centrations in the sample. This problem can bu aolvod successfully In a system
in which the lattice constant shows a noticeable dependence on concentyntion.
Such dependence mostly exists in the case of metal alloys which form supplemen-
tary solutions. By realizing a one-dimensional distribution of concentration for
reasons of simplicity, the problem can be solved in the following manner: on to
a plane massive plate of the component I a plane layer of the component II of the
thickness I < I 16AA is applied. In this connection A denotes the absorptior
coefficient of the X-ray radiation used. It is possible to obtain an X-ray pic-
ture with the interference lines of both components from such a sample. If both
components have a homogeneous lattice with a different lattice constant, two
lines with equal reflection indices can be observed in each aaeo in the X-.raj
picture. If the composed plate is heated to such temperatures as are sufficient
for diffusion, a certain distribution c - c(x) of concentrations over the
depth occurs in the plate as a consequence of diffusion and an equivalentIchange
of the lattice constant a occurs correspondinr to depth. From the linear deFend-

APSTRACT: The solutions of the equations for a bi-phase state of equilibr-itin
in a ternary system are investigated which correspond to that
oase where an unlimited solubility is given for three double
systems with the same components in every phase. Special solutions
of e-,uations of a phase equilibriuw for a ternary alloy are in-
vestigated for that case where the disintegration of the sclutior
is connected with a phase transition. The phases in which al!
three oompo"ents are situated are equal. The relations for t~.e
ternar.1 diagram are made olear for that oase where in three
binax-i systems with the same oomponents an anlimite(i srlublllt~
In each of the two phases is given. There nre 4 figures and
Slavic references.

LBSI'RACT The authors show that the contraction of pressed material
of a single-component (oopper-)powder essentially depends
on the initial porosit,7 caused by the pressure of compres-
sion, or more exactly by the presence of the closed gas-
filled pores. With the increase of pressure the contraction
mat;nitude becomes smaller and furtheron Its sign changes,
i.e. the contraction is replaced by an "increase", the
measur.-_~ments of the pressed material beooming greater
the
sin'ering. The dependence of contraction

sintering of powder-mixtures of cooper with lowmeltinE

formation of closed pores which can lead to an "anomalous
decrease of contraction and also to "increase". The

The authors show that the -echanical strength p of sinLle-

of plastic metal (C dnd at high temperature (10000C)

(0-40%) in such a way as would have to be expected in the

electron microscope and electron diffraction techniques, The results
obtained were compared with a previous determination by the same
authors showing the relationship between thickness and strength of

ABSTRACTs The lecturer takes an attitude to a lecture by 1.1. Xcrn4_lcv
in the first plenary meeting and says that these exllanallicns
had been very interesting. It turned that in a pclycc..-,~Lnent
alloy there is great solubility of various metals. The in-
formation that in a polycomponent system there can be utiservei
a two-phase, three-phase and four-phase equilibrium was not. sur
prising as this corresponds to the phase rules by Gibbs A certain
interaction between the number of comlonents, the 1hases and the
degree of freedom is not to be understood that way that witl~ such
a great number of components there must inevitably also be a Kreat
number of phases. 1.I. Kurnilov believed that it would be
possible to represent grarhically the equilibrium of a ko:ycom-
ponent system on a diagram of a three-component system. T!,js
seems to be based on a misunderstanding on behalf of the lecturer

By these equtions the following simple diagrams can be
calculated#
1) When the decomposition of the solution takes place without
any phase transition, I.e. when in the two-phase equilibrium
two equal phases existj
2) At the presence of the same phase transition in all three
components and of unlimited solubility in higher and lower
temperature phaseal
3) When diagrams with eutectic lines and points occur. The
agreement between calculated ande xperimental values was
