ABSTRACT: Many methods for the quantitative deterrination of cadmium
have been describad in publications (Refs 1-7). Conplexoretric
nethods for the determination of cadmium have recently Ero,7n
in inportance. When research was undertaken into the influence
of substitutes on the solubility of the salts of bnn-.oic acid,
it was found that cadnium salts form a hardly soluble co=pound
with 2-sodium-azinobenz.:~ic acid. This observation led to the
elaboration of a nsetho. for the quantitative deternination of
the cadmium. This method is based on the pre~-.ipitation of cad-
mium by solution of 2-codium-azinobenzoate and further brozato-
metric deterzination of the remaining para-aninobenzoic acid
in the precipitate. An inveotiFation of the compo3ition of the
Card 1/3 precipitate resulted in the following forzula:

for the accuracy of the deter:iination how lonC the ~recij;itate
is left to set. The procipitate has ivell set after 10 to '15
minntes and is easily filterable. Repeated washin- i7ith wnter
gives lower result3 and therefore the precipitate is wash-c-d
with 7ociof alcohol, which does not cause ar,,- decrease of rc,-
sults even after lo rashings. The precipitation of cad-nium
according to this method occurs within a pH ranoc of 2 to 6.5
quantitatively. The exactitude of deterrin"tion is of the same
order as that of tiia gravinetric determination of cadimium
according to the sulfate method. With the aid of the zethod le-
scribed the following salts of cadmiu-n can ' ',it(!r_Jned: the

TITLE: Vacuum Distillation of Metals with Condensrttion on a

PERIODICAL: Fizika metallov i inetallovedeniye, 1959, Vol 7, Nr 6,
pp 862-867 (USSR)
ABSTRACT: The properties of heat-resisting alloys are influenced
to a considerable extent by the purity of the starting
materials. Vacuum distillation is a promising way of
purifying such materials. The authors describe their
use for purifying iron of the method developed in 1952
at the Fiziko-tekhnicheskiy institut ANUaSSR (Physico-
technical Institute, Ac.Sc. Ukrainian SSR) for vacuum
distillation with condensation of the metal on a surface
at a high temperature. The authors consider this more
efficient than published methods and they have used it
successfully for purifying beryllium (Ref 5). The
distillation of the iron was effected in a working vessel
(Fig 1) with evacuation by an oil diffusion pump
(2500 litres/sec) and a type VN-2 backing pump.

with molybdenum or tungsten heating coils, contained the
metal. The heated column directly over the crucible was
generally lined with thin iron shoot, on which
condensation occurred. The temperature of the column
surface was chosen such that iron condensed while the
impurities remained vaporized: the lower part up to 130GOC,
the upper to about 11000C. Assuming as a first
approximation that the condensing metal and impurities
form an ideal solid solution, the authors apply the
Knudsen-Langmuir equation to calculate rates of
evaporation. From a crucib;e at about 1580'C evaporation
of metal occurred at 1 g/cm- hr., 75-80'/0' of wnich was
recovered at a column temperature of 1-250-13000C.
Tables 1-3 show compositions before and after distillation
(single and double) of armco, electrolytic (single only)
and carbonyl irons, respectively. Purification from Mn,
Mg, Cu, S, P, N2 and 0 2 was good and somewhat less so
from aluminium. Considerable contamination from
C,rd 2/4 evaporation of crucible material was possible, but with
double distillation the impurities could be reduced to

0.01%. The resistances of some long-needle single
crystals of iron in the condensate were compared at O*C
and at low temperatures in the laboratory of B.G.Lazarev,
acting member of the Ac.Sc. UkrSSR: the ratio values
agree fairly closely (Table 4) with those of Meysner (Ref 6)
for the purest iron and indicate that the needles were
99.996% Fe. The authors have also studied the purification
of high-carbon (7% C, 73% Mn) and medium-carbon
ferromanganese. The same apparatus was used, evaporation
temperatures being iloo-14oocc. Rates of evaporation
tended to fall through impoverishment of surface layers
with manganese and formation of a graphite layer. Lower
iron contents were obtained when baffles (Fig 2) were
fitted in the column. on the lower baffles, kept at about
1000*C, almost all iron condensed, the manganese condensing
mainly on the middle baffles (750-8000c). Table 6 shows
the composition of the condensate from the third and
fourth baffles. A carbon content of under 5 x 10 3% is
inferred. The purity of the manganese after a single
Card 3/4 distillation is over 99.96%.

TEXTs The object of the present investigation was to explore
the possibilities of low-temperature application of refractory
metals such As Mo, Cr, W, Nb, etc. To this end, the mechanical
properties of Mo were determined by means of the standard tensile
test at 4.2-700 OK2 and the effect of preliminary heat- and
mechanical treatment on the transition temperature from the ductile
to brittle fracture was studied. Mo of 99.95% purity was used in
the experiments, the main impurities consisting of Wa 0.005 Fei
0.01 Ni; 0.017 Ca,, 0.002 Al; 0.002 0; 0.0009 N; o.ooo6 H.
To ensure uniform grain size, the ingots cast in vacuum-are furna--e
were hot-rolled at 1000 OC to 50% reduction in thickness, spark-
machining having been used for the preparation of flat, tensile
test pieces of 7 mm gauge length and 2 mm2 cross-section.

After machining the test pieces were vacuum-annealed at 1280 OC
This treatment reduced the gaseous impurity content and produced a
coarsely-crystalline structure with the average grain size of
200-400 1&. The tensile tests were carried out at 4.2, 20, 77, 2.83,
200, 223, 243, 3009 435 and 700 OKI at two rates of strain, 0.4 and
30 1L/Bec. Some of the results obtained at the rate of stratn of
0.4 ii/sec are reproduced in Fig-3, where the yield point. (a 8)~
U#T.S. (0b) and the true tensile strength (vu) measured in kg/mm2
are plotted against the test temperature (OX). It will be seen that
all these properties increase with decreasing temperature. The
point of intersection of the a. and Ob curves determined the
transition temverature from ductile to brittle fracture, which in
this case was 183 OK. The unusual feature of curves shown in Fig-3
is that they all pass through a maximum at approximately 8o OK,
aince it Is generally believed that the tensile strength in the
brittle fractural region does not depend on temperature. With
increasing rate of strain, both o. and Ob increased, and the
temperature of the transition from ductile to brittle fra:ture was
shifted to 208 OK. The plastic properties of Mo have been found to
decrease with decreasing temperature at a rate which increases wt.th

increasing rate of strain. This is illustrated in Fig.5, where
elongation (6, %) and reduction of area (q., %) are plotted
against the test temperature (OK) for specimens extended at 0.4
(open circles and squares) and 30 p/sec (black circles and
triangles). In the second stageof the present investigation, the
tensile test pieces were subjected to the following treatment;
(1) loading at room temperature and at a rate of strain of 0.4 IL/sec
to attain a stress equal to 0-5 asi (2) slow cooling under
constant load to 77.2 OK and holding at that temperature for 1-1.5
hours. It was found that after this preliminary treatment, the test
pieces tested at 183 OK (i.e. at the critical temperature) exhibited
aome degree of ductility (6 5%). Fig.6 shows the actual load (kg)
versus strain (IL) curves for Mo tested at 183 OK at a rate of
train of 0.4 p/sec for untreated (curve 1) and treated (curve 2)
pecimens. In Fig-7 the elongation (6, %) of untreated(curve 1) and
:
treated (curve 2) test pieces is plotted against the test
temperature. It was found also that no significant improvement in
ductility can be achieved by cooling the metal (during the treatment
described above) to temperatures lower than 77 OK. An increase in

the low-temperature ductility of iron, subjected to similar
treatmentl has been attributed (Ref.li Gindin, I.A., FMM, 1960, 9,
447) to the formation of twins with dislocation-free boundaries.
In the came of molybdenum, the present authors postulate, the
increased ductility attained by this treatment is associated mainly VK
with the stress-dependence of the temperature coefficient of linear
xpansion and with the changes in the mosaic structure of the metal
ubjected to stresses at low temperatures.

TITLE: Metallographic investigation of molybdenum deformed in

PERIODICAL: Fizika metallov t metallovedeniye, 1961, Vol.12, No.1,
pp-132-139
TEXT: Many of the metali-Vith body-cent-red cubic lattice undergo
a ductile-to-brittle transition at sub-zero temperatures. It is to
be expected that as the temperature of this transition is approached
changes occur not only in the mechanical properties of the metal
but also in its microstructure. Since no study of molybdenum at
temperatures lower than 77*C had been reported, the investigation,
the results of which are described in the present paper, was
undertaken with the object of studying the microstructure of
molybdenum deformed in tension at' 4.2 to 7000K. Both optical and
electron microscopes were used in the examination of the specimens.
No etching was used, the changes in the microstructure on the
preliminarily polished specimen surface having been revealed with
the aid of a microinterferometer. Qualitative assessment was made
of the density of slip bands, degree of uniformity of deformation

in different grains, mean magnitude of absolute displacement in
slip, and the dependence of these characteristics on the
temperature and degree of plastic deformation was evaluated. The
results can be summarized as follows. (1) At all temperatures at
which molybdenum remains plastic (that is down to 1830K) it deforms
plastically by the mechanism of slip. An in other body-centred
cubic metals, branched slip lines are formed on molybdenum,
indicating a more complex mechanism of deformation than that
obtaining in face-centred cubic metals. This shape of the slip
lines can be observed already in the early stages of plastic
deformation corresponding to an elongation of 6 = I- 2%~ The
effect becomes more pronounced with increasing degree of
deformation at any given temperature but the effect of heavy
deformation is most pronounced near the ductile-to-brittle
transition temperature. Fig.2 shows (magnified 330-fold) the
microstructure (a) and the interference pattern (b) of the slip
bands formed on molybdenum deformed at 200*K to 6 . o.8%; the
magnitude of the absolute slip was in this case approx 0.25 ),.
In suitably oriented grains (particularly at high temperatures) a

system of interwecting slip lines Is formed. Increasing the
degree of deformation of molybdenum at 240 to 700*K brings about the
appearance of new slip bands and an increase in the displacement
along the slip planes. The development of the prozess of
deformation, however, Is manifested predominantly by growth of the
initially-formed slip bands. Thus, for example, just before the
fracture of a specimen (6 - 38%) at 700*K, the sltp bands may
become 6 to 7 ji wide. The density of the slip lines also changes
with temperature. At 700*X, it is relatively small and slip bands,
spaced at 12 to 15 ji, predominate. At 300*K, the density of slip
bands corresponding to the same degrees of deformation is higher,
the width of the slip bands and the spacing between them decreasing.
With a further decrease in temperature, the density of slip bands
again decreases approaching that obtaining at 7000K.
(2) In addition to deformation by slip (as revealed by the
formation of slip bands) plastic deformation of molybdenum at room
temperature entails a specific mode of deformation, localized at the
grain boundaries and in the grain-boundary regions, This
mechanism operates at relatively low strains 0 to 5%). With
increasing strain some of the regions of localized deformation grow

in size and cracks are formed at the boundaries of these regions
after heavy deformation. The width of these n6ar-boundary regions
can reach 25 to 30 'sl, the relative displacement of adja.~.ent grains
along the grain-boundary being several tenths of a p, This mode
of plastic deformation which has been observed In pure iron at
sufficiently low temperatures (Ref.4; Gindin I.A. and
Starodubov Ya.D. FTT, 1959, It 1794) appears to be a property of
pure metals. The microstructure and interference pattern of the
grain-boundary and the grain-boundary region of molybdenum,
deformed at 300'K to 6 a 20%, is shown in Fig-5a and 5b respectively
(magnified 440-fold). (3) With de:;reasing temperature the
character of plastic deformation changes T-onsiderably. At
temperatures approaching the ductile-to-brittle transition,
fragmentation and block formation precede the appearance of slip
bands. The formation of blocks (whose size, determined with the
aid of an electron microscope, was found to be (2 -3) x 10- cm)
increases the resistance of molybdenum to slip and twinning; the
process of deformation becomes less uniform and fracture takes place
at relatively small strains. (4) In contrast to other metals with
Card 4/9

Metallographic investig,lMon ... E193/E480
body-centred cubic crystal structure, twinning plays a relatively
insignificant part in the plastic deformation of molybdenum. Thin
twine U to 2 U thick) appear in specimens deformed below 246*K
but only in isolated grains. An electron microphotograph
(magnified 11250 times) of a twin (approx 0.5 ~, thick) in
molybdenum deformed at 200*K to 6 x-2% is shown in Fig.8.
A: specific characteristic of twins of this type is the presence of
lightly and heavily distorted zones showing, respectively, as dark
and light bands on the microphotograph. It is postulated that the
highly distorted zone is formed suddenly when a certain stress,
required to initiate the process of twinning, iv reached. The
appearance of this zone is accompanied by the formation of a mosaic
structure in the boundary region and by the formation of block$ and
their elastic recovery. An in the case of iron, growth of a twin
in molybdenum takes place by movement of one of its boundaries;
on reaching the distorted region, the growth of the twin ceases
owing to the strain-hardening of this zone. (5) The specific
character of plastic deformation of molybdenum in reflected in the
manner in which this metal fra.-tures. At 300 and 700*K fracture
takes place along the slip planes and a well-defined nezk is formed

In a tensile test piece. Cracks along the slip planes appear
also in molybdenum, tested at 240*K, but In this case they are
accompanied by cracks along the cleavage planes, the number of
these cracks increasing with decreasing temperature. This is
illustrated in Fig.9 (magnified 440-fold) showing a portion of a
test piece deformed at 2430K to 6 . 18% in which the parallel slip
lines end at a crack along the cleavage plane. On approaching the
ductile-to-brittle transition temperature, and particularly below
it, cracks along the grain- and block-boundaries are formed. Side
by side with the main crack a number of cracks parallel to it but
not traversing the entire cross-,section of the test piece can be
observed. Fracture below the critical temperature is both trans-
and Inter-crystalline, although the latter Is relatively less
pronounced. The decrease in strength of molybdenum below 27'K
has been attributed to the formation of a large number of surface
cracks which cause premature fracture. The formation of the
surface cracks is, in turn, associated with a high concentration of
oxygen in the surface layer. It was concluded from the results of
the present investigation that the character of plastic
deformation of 99-95% molybdenum in the temperature interval
Card-6/9

,studied changes considerably with decreasing temperature. In the'i
plastic range deformation trans-cry8talline slip predominates; at
room temperature this mode of deformation is accompanied by
localized deformation in the grain-boundary regions'. On
approaching the ductile-to-brittle transition temperature, block,
formation plays an increasingly important part and in mainly,
responsible for the absence of twinning at low temperature.
Ductile fracture at 240 to 7000K takes place along.the slip PlAnes."
At lower temperatures, cohesion of the metal is destroyed in the
early stages of the deformation and the main crack develops along,
the block boundaries. There are 10 figures and 9 references:

TEXT,. Previous investigations of the crystalline structure of
Ni--Cr alloys in the temperature range of 1840 to 1930*C

chromium and the possibility was suggested that chromium exists in
five allotropic modifica,~ions, To -erify these assumptions. a
study was made of the crystalline structure of 80 x 10 x 2 mm
chromium specimens with a purity of 99,,94%.. The examination was
mad-s- i~ a high-temperature X-ray camera, which was first evacuated
to 10' nun Hg and then filled in with argon to the pressure of
300 mm Hg. The specimen was heated by passing through it

TLXT: Nickel of 99.981/4' purity (0.006~a Fe, O-C,03'i- Si,
0-001~- Al) was produced using a vacuum distillation column
described previously by V.1-1. Aronenko et al. (Ref.l: Fizika
metallov i mc-tallovedeniye, v.7, no.6, 1959, 369).
Spectrochemical analysis data showed that the nickel prepared
by vacuum distillation from alundum crucibles at 11160 OC had.-
the impurities of Bil 11b, S, Mfg, Sb, Cd and P not exceeding
3 x lo-30.Q. Mechanical strength tests were carried out on
specimens prepared from distilled nickel subjected subsequently
to re-welting under vacuum. The test castings were then cold-
worked to 40-50',") and annealed in order to produce a grain
diameter of 0.06-0.08 mm. Tensile strength specimens were

annealed after polishing in order to remove the effects of cold-
working. It was found that in tensile tests at '20 OC high-
purity Ni behaves in the k3ame manner as pure polycrystalline Al,
i.e. after formation of one or several necks ftirther deformation
proceeds by slip. Impact strength was > 36 and ;;, 3 4 k'g n i / c i a 2-
at 20 and -196 1C, respectively, compared with 11J.9 kgm/cm2 for
commercial grade Ni. Specimens were not fractured but on those
tested at -196 OC clearly visible cracks were observed. The
room-temperature tensile strength was 34.0 kg/mm2; yield
strength 6.7 kg/mm2; elongation 6MV'; and Brinell hardness 56
to 58 kg/mm2. Because magnetic properties of ferromagnetic
materials depend on the presence of impurities, especially gases,
the ferromagnetic anomaly of ductility of high-purity nickel,
which contains only a negligible quantity of gases, was expected
to be indicated more clearly than in ordinary purity nickel.

T_EXT: In the present investigation, the temperature range is ex-
tended beyond 22000C. The specimens were made of tantalum wool,
0.3 mm thick. The metal was annealed in a vacuum at 22000C so as to
remove gaseous impurities. The X-ray analysis was carried out in-a,
hi,-'h-temperature X-ray chamber in a vacuum of 1-3.10-4 mm Hg. The
specimens were heated by an electric current. Only the tantalum
line was observed over the entire temperature range; the parame-
ters of the body-centered cubic lattice vary smoothly with tempera-
ture. This indicates the absence of phase transitions in tantalum.

TEXT: it is shown that the skin formed on the surface of
chromium when heated in air or oxygen consists of two layevs-
an external layer of rhombie Cr20,3 and an internal layer of
hexagonal Cr2N. This was discovered by means of X-ray diffraction
measurements. The structure of the skin formed on chromium when
heated in air and in nitrogen up to 1300 OC was examined for two
different samples; one was chromium cast and rolled in vacuum,
and the other a sample of chromium obtained by condensation frow
the vapour phase. This condensation was carried out at a
pressure of lo-3 mm fig on to a molybdenum plate over a periud of

annealed in air for 45o hours. The skin formed was studied by
means of X-ray diffraction using K.-Cr radiation to improve
definition. Maximum reflection from, the (110) plane wivi obtjined
with the sample placed at 560 to the incident beam, indicating
that the nitride is orientated with the (110) plane parallel to
the surface. In the case of chromium cast and rolled in a vacuum
at a temperature of 1100 OC no structure corresponding to the
nitride layer was discovered; similarly, chromium cast and
rolled in air and in nitrogen at a temperature of 900-120c, OC
showed no structure. It is observed that the structured lay,_,i-
of nitride on the chromium condensed from the vapour phase j_3
much more firmly bonded to the outer oxide layer than in th(, case
of the structureless nitride on cast chromium from which the
oxide layer is easily separated.

ABSTRAM Pointing out that the formation and growth of acicular
crystals-is far more complex than indicated by earlLe.r investigators,
the authors discuss surface structure, strength charteterLatics, and
growth mechanism of Cr crystals with a maximum cross section of
20 x 10-6 m=2 produced by vacuum condensation. Examination under a
standard optical microscope showed that crystals grov in steps; the
mean height of individual steps varied from 1700 to 2300 it. The
growth begins at the basal face and proceeds toward the apex. Under

an electron microscope stepped and complex irofiles as well as smooth
surface regions were also identified. Failure in tensile testqoccurred
bv a cleavage and was not preceded by conspicuous plastic defornation.
Investigations showed that the thicker crystals had a lower strength.
The strength reached 590 kg/mm2 in crystals with mscroscoiic growth
steps. Since appreciable strength was obEerved in cr,,rstal; both vith
a smooth surface and with growth steps, the autLors ausune that the
latter are not formed as a result of dislocation. The discontinuation
of axial growth is attributed to the mechanism of th,- development of
steps on the lateral face. Apparently, with each new layer that forms
at the basal face and reaches tl~z apex, the supply of crystallizing
substance to the mobile-w-hiske tend is reduced by the diffusion of
particles toward the step of the next layer. This was cor-zoborated by
the fact that thin crystals possess a smaller number of Rrowth steps
than thick specimens forned under analogous conditions. Moreover,
the same crystal may be rather smooth near the apex and rouzh in the
thicker portion. The chan6as in the axial growth under cor. it'lons of
temperature control were caused by the changes in the growth mechanism.

ABSTRACT: The obtaining of metal phase diagrams by a multilayer techniquo is
described. The technique, an extension of the work of L. S. Falatnik, V. H. Kosevicli,i
and L. V. Tyrina (ROt. 1961, 21, 229), consists of condensing an appropriate metallic
vapor mixture and of subsequently preparing a thin polished section from the
Icondensate, This technique was applied to the study of the phase diagrarris of the
following systems: Gr-Nij Nb-Sn, Fo-Ta, and Mo-Cr-Ni. The experimental results,
shown graphically (see Fig. I)., were published earlier in three comrauiications by
B. M. Vasyutinskiy and V, S. Kogan (FMM, 1960., 9, 564). In addition, x-ray powder
pictures were taken and. the microhardness of the specimens was determined. The
results are shown graphically. It is concluded that the condermation-
