Effect of titanium admixtures on the surface tension of
nickel and cobalt and on their interfacial tension with
aluminum oxide
Zhurnal fizicheakoy khimiip v. 35, no. 6, ig6i, 1301-1306
TEXT: The present paper deals with the effect of titanium admixtures on
the surface tension of Ni and Co, which metals are used in powder metal-
lurgy as binding agents for titanium carbide, titanium nitride, or
titanium boride. The surface tension is determined by the method of the
drop lying on a horizontal base. For the alloys, 99.99 % pure Ni and Co,
as vell as titanium iodide with less than 0.07 % impurities, were fused
together in the aro furnace. The tables of Bashforth and Adams in a
modified form were used to calculate the surface tension. Besides, a new
table was compiled with the values ~ in direct dependence on x/z of the
drop (Fig. 1) at if .600. The function was ~ -b2/p(2x)2. The surface
tension a was calculated from a .~(2x)j qg. The error of measurement was

3-5 ~. in the system CooToIA120 31 the study was conducted in vacuum at
1.10-4 mm Hg and 16000C. The titanium content was 1.96 ~6. Titanium
admixtures of 0.23 g-atom/l and more showed no effect on the surface
tension. With 0-05 g-atom/l Ti, the inter5acial tension at the boundary
Cc -A1203 dropped by more than 1000 erg1cm . The adhesive power increased
simultaneously with the reduction of interfacial tension. Thus, a
considerable interaction between alloy and A120 3base took place. In the
system Ni,Ti, and A120 31 the same results were obtained as for Co. At a
vacuum of 1-10-4 mm Hg, the specimen was always covered with a thin, but
noticeable oxide layer during the experiment. The same phenomenon
appeared in the case of BeO instead of A120 3 as a base; likewise, in
higher vacuum obtained by freezing the vapors of the oil diffusion pump
with liquid N2 . On addition of Ti, a reduction of the Ni surface tension
was observed. All this changed abruptly if the experiments were made in
H2 atmosphere. In this case, no activation by Ti on the interface Ni- gas
was observed. The interfacial activity increased at the same time. The

interface. In the Ni and Cc system, Ti develops higher interfacial

use of the Gibbs adsorption equ&tion, the excessive Ti concentration at.

the curve). Fig- 4 shows-the reaulto for Cc -Ti and Ni -Ti on A120 3 j ,In

layer is 2.7-10- a cm. It is assumed that the lattice nodes occupied by

TE(T: The authors attempted to check how far Cu-Ni alloys represent ideal
systems and obey Raoult's law. For this purpose, the surface tension of Cu,
Nil and their allo 9a was determined by measuring the maximum pressures in a
gas bubble at 1550 C. Measurements were made in pure He or H Apparatus
and method have already been described by the authors (Sb. IIS?royeniye
veshcheetva i spektroakopiyall (Structure of substance and spectroscopy),
78, ig6o, Izd. AN SSSR). The total amount of impurities in the metals used
was not higher than 0.1%. The alloys of different composition were molten
in crucibles of pure A1203 in a high vacuum. Their composition was checked
by chemical analysis. For the surface tension of Cu-Ni alloys at 15500C,
the authors give the following values (rounded-off to 5 erg/CM2):

according to A. A. Zhukhovi takiy (Zh, fiz. khimii, 18, 2141 1944). This

PERIODICAL: Akademiya nauk UkrRSR. Dopovidi. no. 2, 19621 192-194
TEXT: The tantalum-vanadium alloys were prepared by t he method of
Yeremenko et al. (Ref. 2: ZhNKhq 5, 22909 1960). Then they were
annealed and tempered at 4 different regimes, ranging from tempe
ratures of 1000 to 14000C, and lasting from 5 to 200 hours. The
boundary of the T-phase was determined metallographically. The mi-
crostructure was determined by means of various etchants, depend-
ing on the composition of the alloy. A table shows the phase com-
position of the alloys at various temperatures. Four types of mi-
crostructure are shown in figures. The first shows the structure
of a homogeneous 3-solid solution alloy; the grain boundaries are
sharp and clean. Another figure shows the microstructure of the

same alloy after low-temperature annealing; thereby small (f-phase
formations are noted. Further, an alloy with a considerable amount
of d-phaseis shown, and (lastly) the microstructure in the region
of homogeneous ar-phase. The d-phase has very great hardness. The
microhardnesst determined by means of the device NHT-3 (PMT-3) , of
the T-phase in alloys containing 32.0 and 41.5 atom% Ta, ranged
between 1070 - 1260 kg/mm2. The line digrams (of an X-ray picture)
of a specimen containing 32.0 atom% Ta is shown. Nearly all the
lines of the (r-phase were identified by the tetragonal lattice. Cal-
culation of lattice parameters showed that the e-phase in alloys
containing 32.0 atm% Ta has parameters a = 6.15 U and c = 8.85 kX.
According to the data of W. Rostoker and A. Yamamoto ((Ref. 1:
Trans. Amer. Soc. Metals, 46, 1136, 1954), these parameters are
a = 6.104 U and c = 8.833 U. A state diagram of the Ta-V system
is shown, us�ng data of Ref. 1 (Op.cit.) and the solidue-tempera-
tures found in Ref. 2 (Op.cit.). There are 3 figures, 1 table and

TEXTi Surface tensions and densities of Cu-kl alloys of varying mixing
proportions were studied. The alloys were fused in cruciblesof pure over-
burned and recrystallized aluminum oxide, in which also the further tests
were made. Surface tension was measured by a method elaborated by the
first two authors (Ref. 9: Fizika metallov i metallovedeniye, 110), 863
(1961)1 Ref. Ili Zmochuvannya ridkimi metallami poverkhent tugoplavkikh
spoluk, Izd. AN USSR, Kiyev, 1958), in which particularly large and strict
symmetrical drops of the test substance are usedl thus, the error in
measurement is significantly reduced. The density of the melts was deter-
mined from the volume of the drop (ascertained from the ratio d/2h, where
d is the equatorial diameter and h the height of the drop on d, and with
the aid of a table of F. Bashfort et al. (see below)) and from its weight.

Measurements were made in vacuo (1 - 2.10-5 mm Hg) between 700 and 12500C
Resultai The temperature coefficient of the density of the alloys is
strongly dependent on the Cu-Al mixing ratio (Maximum dQ/dT at , 951; by
weight Al). The isotherm of the specific volumes of the alloys (measured
at 11000C) shows that fusion of the components results in volume contrac-
tion owing to chemical interaction. The surface tension of the alloys de-
creases isothermally (measured at 1100 and 12500C) with increasing Al con-
tent. (Surface tension of Cu at 'the temperatures indicated j1320 - 1350
erg/cm2'of Al 400 erg/cm2). In accordance with the sidehiometric pro-
portion of CuAl 39 the isotherms of the alloys show a break after which the
surface tension decreases very rapidly with increasing Al content. For
the isotherm at 12500C the break becomes less sharp owing to the increasing
dissociation of Cu 3Al at elevated temperatures. According to the
classification of N. A. Trifonov (Ref. 141 V. Ya. Anosov, S. A. Pogodin.

(Principles of physicochemical analysis. Published by AS USSR, 1947))the
isotherm of the surface tension of the Cu-Al system belongs to the third

TEXT: The systems Ti-C-Ni,, TI-C-Cr, and Ti-C-Mo were studied in an
attempt to determine the true phase composition of cermets contain-
ing iC with Ni, Cr, or Mo. The solubility of Ili in TiC at 1000-
120C is 0.7% by wt.; TiC-Ni alloys containing over 0*7% Ili are
composed of two phases, the microhardness'of one of the phases being,/,
3000 kg./sq.cm. The section TIC-141i through the Ti-C-Ni s-ystem; as
well as the TiC-Cr and TiC-1,1,o sections through the respective ter-
.nary systems, are quasibinnry; the melting of.alloys containing
over 5% Ni starts at 1280-13000C, In the system Ti-C-Cr. the form-
ation of a now phase Cr C,, is observed when small amounts of TiC
are added to Cr; the 0TiC28r 6alloy containing 20% Cr is composed of

throo phases whose microhardnoss (300, 1000.. and 3000 kgoeq9ems)
corresponds to that of solid solutions based on Cr, chromium car-
bide, and TiC respectivnly. Til-Cr alloys containing 52,05 and
v
63.0,~~ Cr are composed of two phases - Cr-based and TiC-based solid
solutions. All alloys in the system Ti-C-Mo are composed of two
phases, with microhardnossos of 300 and 2400 kg./sq.cm.; x-ray data
reveals that these are Mo-based and TiC-based solid solutions., The
experimental data for this system disagrees with the data of Albert

point of inflection corresponding-An composition to the congruently malt-

it was of interest to study the surface properties of the MI-Ga systom and
.to compare them with the phase diagram.
The temperature and concentration relationships of the density of
;alloys in the Ni-G& system were determined. It wag established that
.specific volumes of alloys both in the molten and in the solid states differ
liharply from additive values.
The temperature and concentration relationships of-the free surfaeG

the negative departure of the system examined from idoali~ty.
The isotherm of a, f6r' the Ni-'Ga'a'ystem has a more flattened appear-
.ance compared to the isotherm of d' for alloys in the Ni-Al systemg vhich
js accounted for by the significant dissociation of intermetalliden in the

The temperature dependence of the regional corner of miscibility

ABSTRACT: The results of the investigation were compared with diagrams of conditions
for the same systems. The authors concluded that the isotherm of surface tension
for alloys in a system with inorganic solubility in the solid, as well as the liquid
state, was given by Zhukhovitskiys equation (A. A. Zhukhovitskiy, ZhM, vol. 18,
1944, p. 214) for an ideal solution (nickel-copper). In the binary liquid systems
examined, the component with the least surface tension had an active surfacerela-
tive to the second component. The lowering of the surface tension in these systems

and the isotherm of the surface tension showed a very slight deviation of the sur-
face tension in alloys from the additive values. It was established that in systems
with maxima on the fusibility curves corresponding to the congruently malting
electron compounds having an electron concentration of 3:2, extreme points in
form of a maximum (nickel-beryllium) or a point of bend (nickel-aluminum) were
tected on the isotherms of surface tension. In the nickel-tin system, such poinz:s
.were not detected although the isotherm in the region of the composition of the
