Ageyev, N. V. Crystal Chemistry of Titanium a
and Campounds
This is a review of.studies in the crystallography of metallic
titanium and a number of its compounds. Intermetallic compounds
covered are those of titanium with metals of Groups I, III, V,
VI, and VII. Data on compounds of titanium with nonmetals and
metalloids of Groups III, IV, V,.VI, and.VII are also presented.
Kornilov, I. I., and P. B. Budberg. Con*stitution Diagrams of
Titanium-base Systems 31
Binary and ternary titanium-base systems are studied. It is
~sho,wn that in binary systems,'the nature of the chemical reaction
between titanium and the given element is determined by the
position of that element in the periodic table. Formation or non-
formation of a solid solution is dependent on the*degree of simi-
larity between the two elements. Data on the solubility ofl.vari-
ous chemical elements in titanium are given in a number of tables,
Card 2/6

diagrams of ternary titanium-alloy systems is Included. It is
stated that these diagrams represent virtually all known data on
these systems published up to 1955.

ABSTRACT: The authors have carried out an investigation of the
microstructure and properties of yttrium and its alloys
and the reaction and in4uence of the element on alloy
properties. Yttrium foei-the in*vstigation was supplied
by D.D. Sokolov2 L.A.Izhvanov and N.P.Vershinin. The
Purity of the metal was 96.5%, its microstructure
characterised by inclusions of a second phase bofh- at
grain boundaries and within grains (Fig 1). The Brinel
hardness was 80-85 kg/mmP- and the ultimate strengths In
tension and compression were 16 and 82 kg/mm?-., It was
found'that yttrium is completely dissolved by cqrium;

ABSTRACT: Up to relatively recently, it was not possible,to
produ,~-.e Fe-Al alloys with alLuninium. content of about
16 wt.% with an elongation at room temperature
exceeding The cause of such.brittleness was
obvLously the large quantity of non-metallic Al 2 03
inclusions, the presence of a considerable quantity of
admixtures in the original iron and also the formation
of chemical compounds and ofsuperstructures.~ The
increase Id brittleness is also brought about by the
tendency of these alloys to form a large number of micro-
cracks due to low-temperature conductivity and also due
to the tendency to grain growth. The authors investigated
Cardl/5 the effects of applying rare metals for improving the

mechanical properties of alloys of this type. The
alloys were produced using as starting materials
electrolytic iron of 99-58%o purity and aluminium of
99.9% purity. The influence was investigated of alloying
additions of the following elements: Zr, Ti, Ta, Nb, VS
B- Mo, Ce.. The additions,were selected for ihe purpose
o~ determining their influence,as deoxidation agents,
inoculation substances and carbide-forming substances
The chemical composition of the investigated 38 alloy;
is entered in Table 1, p 40. The effect of the individual
elements on the mechanical properties was investigated
and also on the magnetic and the technological properties.

The st-rangth of the alloys increases from

PP 424-434 (USSR)
The phase diagram of the system Mo-Re was drawn on the basis
of the results obtained by physico-chemical and analytical
investigations (determination-of the melting point, mi-.--ro--
scopic, X-ray, and phase analysesq determinations of the
speei fic'electric resistance, and detle,rmination of solidity).
.For the produotion of the alloys max-Imum purity rhenium
(99.8%),and molybdenum,(99.6%) were used as initi Ial mate_~_ials.
The pressed samples weresintered in vacuum at.15000- In the
system rhenium-molybdenum solid solutions containing 58 weight%
rhenium'(42 at % Re) are formed at temperatures near the
..melting.point. The solidity of molybdenum alloys increases,
in the field of solid solutions, from 130 kg/mm2 (pure
molybdenum) to 205 kg/mm2 for -the alloy containing 53'weight7'af

upon increase of rhenium content the lattice constant in the
solid solution is reduced and is 3.12 X in the alloy with
53 weigh-,,- %. The determination of the electric.resistance con-
firmed the range of solid solutions. The specific electric
resistance of pure molybdenum is 6i.6.10-6 ohm-cm, and rises
to 27.6.10-6 ohm-cm i,n alloys with,42 weight %Irhenium. In Ithe

ABSTRACT: The phase diagram.of the alloys chromium-cerium,(up to,
30 weight ~ cerium) was investigated by micro-structure analy-
ses, thermal analyses) and X-ray analyses. Electrolytic
chromium (99-5%) and metallic cerium (99%) were used-as
initial materials. In the system chromium-cerium separation
into two layers takes~place i-n a wide,range (10 to 50% cerium)
upon liquid-state at 17600o The analyses of the micro-structure
of the alloys show that in the field of the solid solution
the s -olidity of the alloy rises upon increase of cerium
conteht. Cerium additions amounting from 1-1-5% to chromium
increase the solidity of chromium and refine its structure.

annealed in evacuated quartz Aouble ampoules in a Silit
furnace at 1100 0C for, 50 hours. Alloys richer in tin,
in view of their lower melting point, were annealed at
200 OC for 100 hours. One part of the alloys
(containing 85-100% Sn) were deformed by approximately
60% by cold forging, prior to annealing. The limit of
solubility of tin in niobium was determined by quenching
and testing the microhardness., Water quenching of the
alloys was carried out in evacuated quartz double
ampoules from the following temperatures: 800 OC, (after
soaking for 100 hours) and 1100 OC (after soaking for

of 20 g. The hardness of the alloys was tested in a
Vickers hardness testing machine at a load of 5 kg.
X-ray investigations of annealed alloys were carried out
in a Debye camera with a Cu-irradiation. The malting
temperature of the more refractory niobium-tin alloys
was determined by the drop method, using an optical
pyrometer. The temperature was measured at which the
first drop appeared in the drilled-out centre bore of a
specimen; the ratio between the depth and the diameter
of the bore was approximately 1+; this ensured
practically absolutely black body conditions. The
thermal analysis of less refractory alloys (between 30
and 100% Sn) was carried out with a Kurnakov pyrometer
which uses differential registration, in sealed quartz
ampoules. In this case the highest measured temperature
did not exceed 1000 OC. The determination of the rate

transition metals 6 phases are o.aserved, i.e. compounds with
an isomorphous structure of the g-u type. According to modern
opinions the condition for the formation of the 6 phase is as
follows: if one of the components belongs to group VII or VIII
of the periodic system the second component must be of group
V A or V1 A. However. the F- phase of the iron-r-henium system
has also a crystal lattice of the 6 phase (Refs 1, 2). Since

ABSTRACT: It is the object of.the present study,to determine some of the,
properties of hafnium and to investigate recrYEtallization- and
deformation-processes. From metallographic and X-ray analyses,,
as well as by determining hardness, the authors derived the
recrystallization diagram shown in figure 1. Hafnium is a
dimorphous metal, the hexagonal 04-modification changing in-to
the cubic body-centered A -modification at higher temperatures.
Hafnium iodide bars of coarse structure were used as original
material. The physical properties of these Hafnium iodide bars
are given together with a description of the elimination of the
coarse structure. The deformation was carried out in eight steps-
from ranging 50 to the maximally tolerable deformation of 60~6.
Vacuum-annealing was performed in seven stages between 750 and

deformation,at 8500 C after 201,7v' deformation, and at 7500 C
after 40% or more deformation. Annealings within the tempera-
ture range of the *,e -modification yield a fine-grained
polyeder structure with grain sizes of between 25 and 40,,,&-
after 30% to 45% deformation. Annealings above the temperature
of the polymorphous transition gives a coarser grain (240~)
and a marked structural change. The similarity of the
deformation- and recrystallization properties,between hafnium,
titanium and zirconium is pointed out. Also, theirod - and
~_modifications are compared and their high plasticity
stressed. By their hardness andleold workability they are
arranged in the following order:.titanium - zirconium
hafnium. It follows from the recrystallization diagrams of the

three metals that they also have similar grain sizes.
Finally, the temperature stability of these metals and -their
alloys is emphasized. There are 3 figures and 11 references,
6 of whic h are Soviet.

(USSR)
.ABBTRACT: Nn is known to belan anomalous metal with regard to combining
forces between the atoms, the crystalline structure, etc.
(Refs 1,2). Active interaction with the elements of the sub-
groups IVA, VA, and VIA is typical of rhenium. In connection
herewith, 6- and X-phases are formed in binary systems ,
(Refs 3,4). Mn and Re are anal6gous with regard to the form&-
tion of oxides, acids, etc. It ieq however, unknown whether
they are analogous with regard to interaction with metals.
Table 1 shows distinct differences of the physical properties
of Mn. Re, and~Tc. Great similarity of Kn and Re an to the for-
~mation of metallic phases can be soon in analyzing~tho int*rac-
tion of Un and Re with transition metals. Figure I shows the de-

(with regard to Mn and Re) on the group number of the periodic
system for all transition metals (Ref 6). Figure I shows the
compounds formed with a corresponding transition metal in a
binary system of Un or Re. Mn and Re and the above elements of
the subgroups IVA and VA form Laves phases with a structure of
the type MgZn 2 and .MgNi2 (ZrRe 2' ZrMn2 T'NA2 T&*n2'Nbnn2 ). All
these compounds are formed from the liquid phame and are stable
up to room temperature. It may be concluded therefrom that there
exists great similarity between Mn and Re in the formation of
alloys with transition metals. This is, provedl above all9 by
-the type of interaction with elements which are at right and at
the left of group VII in the periodic system. Compounds are.
formed with the metals of the subgroups IVA, VA, and VIA. Solid
solutions on the basis of more simple structures or compounds
with a simple structure, however, are formed with metals of
group VIII. In binary systems, Un and Re form the same type of
phases with the metals of the titanium-, vanadium-, and chromium
group. Mn and Re show a great tendency towards formation of
/3 6-phases. The structurecorreeponding to the low-temp 0

binary systems can not be completely classified on the basis of

similar way an Re. The comparatively d4stinct classification of
the binary systems of-transition metals with Nn'and Re as well
as a restricted set of phases existing in these systems are ob-
viously related to the key position of subgroup VIIA amiong'tran-
sition-metals. There are I.figure, I table, and Treferences,

Studies have been made of recry-stallization of rheniim, and of alloying with
tungetenj, nickel (in Ni-Cr alloys)~ and with titanium ond its alloys. Rhenium
additions improve both room and elevated temperature properties and increase the
initial recrystallization tenperatures. Solid solution tungsten alloys have
increased workability and electrical resistance. Applications for rhenium alloys
are promising for thermocouples, electrical contacts and scme vacuum tube parts.
Results are given a study of rheniwn as a contact material.

solid solubility of neodymium in aluminium does not
exceed 0.21". A eutectic, containing approximately

investigated concentration range- the existence of.two
intermetallic compounds, NdA14 and NdAl2 , has been
observed. The former is formed as a result of a peritectic
reaction at 1 250 OC;.the latter crystallizes out from the
liquid phase at 1 450-0C. Owing to Ithe formation of the
intermetallic compounds, addition of neodymium to
aluminium increases the strength of the latter metal.

alloys with high molybdenum and vanadium contents is a high
oxidation rate. Variation of hardness with composition in binary
and ternary alloys corresponded to property changes c haracteristic
for a continuous series of solid solutions. Variation of scaling
resistance with composition does not show such a relation. In
general, increase in scaling resistance of the ternary niobium
alloys occurred at,a lower degree of alloying than with binary
alloys. Some ternary alloys,oxidized faster at 1000 than at,

TEXT: Rhenium has been suggest Ied,.as a possible alternative
for tungsten for use in the electro-vacuum industry, but it is
very expensive. Therefore an investigation of tungsten-rhenium
alloys.was carried out. Alloys were prepared in an arc furnace
and by powder metallurgical methods. The complete range of
alloys was studied by metallographic and X-ray analysis, by micro-
hardness measurements and by measuring melting points. The

Physico-Mechanical Properties of Tunssten and Rhenium
There was a wide range of solid solutions of rhenium Iin tungsten
(up to 30%) at high
temperatures
, with decreasing solubility as
the temper* _
ature was decreased. The compound WpRe3 formed by a
reaction possessed a
peritectic high hardness (about 2000 kg/mm2)
-
and was,brittle. A method was developed for preparing wire of
diameter 12 microns from alloys with a maximum rhenium content of
20 wt.%'. The wire was prepared by hot-working samples prepared
by powder metallurgical methods. The introduction of rhenium into
tungsten raised the temperature of the beginning of recrystalliza-
tion by 200-400 OC depending on the rhenium content. Grain growth
of tungsten-rhenium alloys was l ess intensive than that of
tungsten. The tungsten-rhenium alloys.retained a high strength
and possessed considerable ducti lity after annealing at 11100-
1950 OC. The initial strength of 100 micron tungsten wi re was
320 kg/mm2 with an elongation of 1-50%.
After heating at 1950 OC
the strength decreased to 80 kg/ .
mm2
S and elongation was 0. The
alloy containing'21% rhenium in these conditions decreased in
strength from 370to 150 kg/mm2 and the elongation increased from

this alloy was 1807190 kg/mm2 and its elongation A-2oa%. The
strength of wires of the alloys was higher than that of tungsten
wires at all temperatures, although an increasein temperature
resulted in a decreas'e in strength. At 1400 OC the U.T.S. of

respectively. The limiting testing temperature of alloys
containing 10 and'2056 rhenium was 3000 OC, or 3000 higher than the
limiting temperature of tungsten or alloys containing I and 3%
rhenium ' The hardness of cast tungsten-rhenium alloys was
tested in the range 20-1000 OC. At 8000C alloys containing
10 25 and 755/a rhenium and pure rhenium had a hardness of about
20; ks/mm2. Tungsten and alloys containing 101,10 rhenium had a
hardness of 100 kg/mm'-. , The electrical resistance of 50-micron

TEXT: The authors describe their Work on the vanadium-
chromium phase diagram. Their starting~materials were:
alumino-thermic vanadium (95-50" V, 1.0 Al, 0.15 Fe, O.2,C, 0.3 Si,
considerable concentration of' oxygen) and electrolytically refined
chromium (99.90,-D' Cr, 0.02~Fe' 0.03 Si, 0.02 N,0.002 H, 0.0023 0).
Alloys were are melted (non-consumable tungsten electrode) under
helium, each ingotof 50 g being remelted four times and analysed.
Compositions of the charges and alloys are shown in the first two
main columns of a table. Solidus and liquidus temperatures were,
determined under argon in an apparatus constructed in the
Laboratoriya splavov redkikh elementov IMET AN SSSR .(Laboratory o .f

,TEXT.- The authors describe experiments carried out to qetermine the
effect of vanadium on structure and properties of Monel metalyand constant-
an. The alloys were prepared at the Balkh 'ashskiy zavod po obrabotke tsvet-
nykh metallov (Balkhash Non-Ferrous Metal Working Plant) and the vanadium
was introduced in the form of a Ni + 10 V alloy. They were tested as to
microstructure, hardness, electric resistance, strength and plasticity dur-
ing stretching. The stretching tests were carried out at temperatures of
from 20 to 1,1000C. Additions of vanadium of up to 0-5~o had no effect on
,the microstructure of either the Monel metal or the constantan. Measuring
the hardness of the alloys in thedeformed and tempered phases showed that
