ABSTRACT: The kinetics of the disintegration of the solid solution
of 60:25:15 type Cr-Mo-Fe alloys were investigated for
chromium contents of 62 and 56 wt.% respectively. It was
found that at 10500C these alloys are in the range of the
ot-solid solution. At 9500C both alloys undergo decomposi-
tion of the solid solution accompanied by the separation
of the a-phase of the composition Cr(MoFe); this disinte-
gration process brings about an increase in hardness of
the alloys. At the temperatures 850 and 7500C the allo
containing 612% Cr is at the boundary of the a + (a + Z
phases . A decrease of the Cr concentration in the alloy
to 56% leads to a disintegration of the solid solution at
these temperatures. At 8500C the alloy gets hardened less
than at 750oC; in the latter case a finely dispersed phase
separates out during ageing. The kinetics of the disinte-
Card 1/3 gration of the solid solution of a 60:15:25-ty e alloy was
investigated in the temperature range 1050-750EC; at all

Phase-transformations in chromium rich, Cr-Mo-Fe alloys,
(Cont.) 24-4-4/34
the temperatures separation of the a-phase from the solid
solution was observed. Increases in hardn -ass were ob-
served at holding times up to twenty hours. After a 100
hr holcling, the hardness of the alloys dropped. The
volume of the solution during the disintegration of the
alloys of both types changes very little, namelyp within
the limits of + 0.002 U. Comparison of the kinetics
of disintegrati7on of the solid solutions type 60:25:15
and 60:15:25 leads to the conclusion that the speed of
the diffusion procesF increases in the case of substi-
tution in these allo, of iron for molybdenum. The high
$Peed of the diffusi-n_proeess.-An the 60:15:25 type
illoys and their coarse grain crystalline heterophase
structure at temperatures below 10000C should lead to a
4eterioration of their heat resistant properties. Th-~
Xinetics were studied- of the ageing of a 60:25:15
containing 0.07% C, 2 .5% Sit 1.5% Al'. It was establislied
Card 2/3 that in addition to the a-phase in the temperature range
~50 - 7500C a finely dispersed phase rich in Mo is sep.-
qrated in the alloy which is probably attributable to
qarbides of the type U2 3 C6,; de hardening df-tbLe alloy
during ageing after holding times*exceeding.50 hours, is
due to coagulations of this phase. Separation of the

carbide phase from the solid solution leads to consider-
able-decreases of the lattice constant of the solid solu-
tion. Introduction of titanium as an alloying-element
into 60:25:15 type alloys leads to an,increased hardness
$n the temperature range 1050-75000 and no dehardening
was observed in the case of long duration ageing (up to
1000 hours)'. Investigation of the ageing of deformed
Olloys of the type 60:25:15 both alloyed and non-alloyed
phowed that introduction of titanium reduces-their speed

tested specimens is given in a small tablet p.23.

An obituary note for X.T.Gudtsovt one of the most important
Soviet scientists and metallurgists (1885 - 1957)- Gudtsov
obtained his high-school final certificate in Kursk 1902, finish
ed the Petersburg Polytechnic Institute in 1910 and worked in
the laboratory of the same institute with A.A.Baykov. From
1913 - 28 he was head of the metallographic laboratory in the
Putilov-Works at St.Petersburg. From 1928 -.33 he was at the
4-
Leningrad Institute for iie.als and founded a laboratory for
the scientific research of heat treatment at the Leningrad
Polytechnic Institute..He took his degree of Doctor of Technical
Science in 1934. He was elected regular member of the Academy
of Science of the U.S.S.R. 1939. He became one of the leading
collaborators fo the then foLnded Institute for Metallurgy of
the Academy of Science of the U.S.S.R. It was he who develped
the scientific thesis that under certain conditions carbon
in steel can diffuse in the direction ot its smaller as well
as of its greater concentration.

He solved the problem of the formation of flakes in st?el
and devoted close attention to the interaction of-atoms of
various coffiponenis in crystalline media and on the dependence
of these interactions on the elasticity of the medium. The
hypothesis on the atom groups which can form and decompose
was worked out as a result of this research work. Investigations
of the structure of hardened steel were carried out by him
together with Kurdyumov and Selyakovt in the course of which
work the crystalline structure of the martensite-lattice was
found. His pedagogic activity began in 1915 when he hold
engineers' courses in the Military SAool f6r motorvehicles.
Since 1943 he has occupied the professorial chair for heat
treatment at.the Moscow Institute for Steel. Besidesq he parti-
cipated in designing the Stalingrad tractor works. (1 illu-

(on the nature of systems of titanium, magnium, aluminum, chromiumf
tungsten, molybdenum, as well as of the metals of the VIII group
of the periodical system). The wish was expressed at the conference
that a commission for coordination be attached to the Institute
for Metallurgy.

TITLE: The Phase Diagram as an Expression of the Interaction

ABSTRACT: The nature of the interaction between the atoms is a
complicated function which not only depends on the type
of atoms but also on the concentration in the reacting
surroundings. In systems in which metals occur as compo=
nents which possess similar chemical properties phases
with variable composition may occur. Free electrons which
are characteristic of metallic compounds may also occur
in such phases. N. S. Kurnakov assumes that phases of variab.
le composition can be of the type of daltonides or bertoli=
des. The formation of daltonide or bertolide phases is depen=
dent on the free energy of the neighboring phases. The lower

the developing phase is. When the difference of the che-
mical properties of the atoms is not high, the tendency
of the occurrence of a metallic binding of solid solutions
prevails in the interaction between such atoms.. The incli-
nation to the formation of chemical compounds between such
atoms is very small. In the solid solutions a portion of the
electrons can be taken up by the atoms. They do not parti-
cipate in the filling up of the energetic zones. The spreaw
ding of the solid solutions in the alloys is beside the
electron-concentration also dependent on the atomic volume
as well as on the mutual polarization of the atoms. The in.
teraction between atoms, dependent on the position of the
atoms in the periodic system of D. E. Mendeleev~ determines
the formation of certain chemical compounds, the phase of
variable composition and the solid solutions. The inter.
action between the atoms influences the phase diagrams of
the systems and the quantitative relation between the phases.

ABSTRACT: The possibilities of determination of the dissolvedf
gaseous impurities in a-titanium by the amount of the
crystal-lattice constant c by means of radiographic methods
were described in the present paper.
The amount of the crystal lattice constant a changes
according to the quantity of oxygen. The orystal-lattice
constant c of a-Ti amounts to 4,68 R and may undergo a change
Of UP to 4P82 R due to oxygen contaminations which is present
as a solid solution with a-Ti. The amount a can be
calculated with an accuracy of up to 0,05 ~o by means of
radiographic investigations.

Impurities in Titanium by the Amount of the Crystal-
Lattice Constant
0,8 % on the amount of the crystal lattice-constant c is
determinable, since its influence on c takes place almost
additively. With such samples, first the amount of
contaminations and the concentration of oxygen is
determined by the difference of samples with known
nitrogencontent by the determination of the amount c.
The radiographic method for the deterrination of the
oxygen content can be successfully applied in such
metalsamples in which the content of metallic impurities
and nonmetallic influenoes is almost constant. The
character of the distribution of oxygen, or nitrogen in
titanium metal and in the oxides of the nonmetallic
inclusions can also be indicated by the determination of
the crystal lattice constant c.

Binary and ternary titanium-base systems are studied. It is
shown 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-

ABSTRACT: The continuity and discreteness in the chemical structure of
crystals has been discussed in consideration of present as-
sumptions regarding the interatomic interaction. The structure
of the free atoms.in normal condition can be determined by
optical spectra and X-ray SDectra. The energy state of the
electrons in the crystal field can be considered a developed
energetic state of the free atoms. Spectral investigations show
that the sharp lines in the spectrum of the free atoms are
blurred upon crystallization. Figure 1 shows the spectrographs
of aluminum vapor with sharp lines and of solid aluminum at
the wavelength of the X-ray spectra of the atoms in the crystals.
The energy state of the free aluminum and of the combined atoms

The Continuity and Discreteness of Interatomic Interaction in Crystals
consist of one kind of atoms and have an interatomic inter-
action of homopolar (discrete) and continuous (metallic)
character. Crystals having different atoms can form solid
solutions by heteropolar interaction, The heteropolar bonds in
the solid solution depend on the chemical properties of the two
kinds of atoms forming the solid solution. Crystals having dif-
ferent kinds of atoms with well-defined homopolar interatomic
interaction form chemical compounds. Crystals having different
kinds of atoms and discrete-uninierrupted interaction form
compounds of varying composition. Such chemical compounds are
NiAl, MgAgj CuZn. These compounds contain heteropolar, homo-
polar and metallic bonds at the same time. Metallic bonds
promote the formation of solid solutions. There are 8 figures

ABSTRACT: The conditions for the stability of the ~ -phase In titanium
alloys containing iron and nickel were investigated in the
meta-stable state. For the purpose of producing the alloys,
magnesium-thermal titanium, iodide titanium, carbonyl iron,
and electrolytic nickel was used. The chemical composition
of the alloys Ti-Fe and Ti-Ri is given by tables I and 2.
The alloys were produced in an electric are furnace with
tungsten electrodes in an argon current. X-ray and
microstructural analyses of the alloys and hardness- and
microhardness determinations were oarried out. Figure 1
shows the constructed meta-stable diagram of the phase
composition of the titanium - iron alloys ' The diagram

the method of determining hardness and micrahardness. The
structure and midrostructure of alloys hardened at 900 0 are
shown by figure 5, The diagram shows that with an increase of
the iron content in the alloys the p-phase in the alloys
becomes stabilized. The maximum hardness of the alloys,with

ABSTRACT; On the basis of references 1-10 the authors give a total
survey of the known compounds of titanium with the elements of
the IV group (Si, Ge, Sn, Pb) (Fig 1). In the system Ti - Si
the following series is set up according to the decreasing
stability of the chemical bond by means of the formation heat
(Fig 2), temperature dependence of the thermal capacity (Fig 3)p
and the minimum of the interatomic distances in the lattices
(Table 1): TiSi--v,.Ti5 Si3-P-TiSi 2' For the Ti-Ge compounds the
series TiGe-P-Ti 5Ge 3--jP-TiGe2is obtained. In the system Ti-Sn
(Table 3) only the crystal structure of Ti 5 Sn3 is exactly in-

T16 Sn 5* on the basis of the interatomic distances it is proved
that the Ti5Sn3 bond is stronger than that of Ti 3Sn. The
comparison of the interatomic distances in the systems Ti-Si,
Ti-Ge and Ti-Sn (Table 4) shows that the substitution of
silicon by germanium or tin leads to a weakening of the bond.
This weakening increases with decreasing titanium content of
the compound: Ti5X3 T i X - T i X2* From this the lack of titanium-
tin compounds with high tin content may be explained. The com-
parison of the atomic volumes of the elements with the volume
reduction which occurs in the formation of the systems in-
vestigated (Pigs 11,12) leads to the conclusion that in. the
system Ti-Si electrons pass from silicon to titanium, in the
system Ti-Ge the reverse process takes place, whereas no
electron transition takes place between titanium and tin.
Taking the free energies of the system Ti-Si (Pigs 8-10) as
example it is demonstrated that the formation of a peritectic
is not bound to lead to a lower stability of the forming com-
pounds. The formation of a compound due to peritectic reaction

ABSTRACT: Among the numerous known binary and ternary systems of
transition meta'-'s 6 phases are observed, i.e. compounds with
an isomorphous structure of the fl.-Ti 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 VI A. However, the E phase of the iron-rhonium system
has also a crystal lattice of the 6 phase (Refs 1, 2). S-ince
the latter system does not correspond to the above-mentioned
condition the e phase cannot be explained within the
framework of the existing theories (Refs 3, 4). The al'Loy

ABSTRACT: Rhenium tends to the formation of 6- and phases in binary
systems (Ref 1). These phases have relat a-crystalline struc-
tures and are widespread in various binary and ternary sy-
stems of transition metals. The binary systems of rhenium are
therefore suitable objects for investigating the nature of
the latter. Pruceeding from their properties it may be assumed
that the tendency to the formation of phases in the mention-
ed binary, systems is widely determinedN-y the atomic volume.
The amount of the relative difference of the atomic radii
may be computed for transition metals in the rhenium systems
by using the data from table 2 according to formulat

the sub-group number of the element in D. I. Mendeleyev's
periodic system in a diagram. In this diagram those metals
are given which according to the data from publications
(Refs 8 - 14) enter into compounds with rhenium. From these
diagrams it may be seen that +he -~-phase is formed only with
those metals of the sub-grou s 1VA, VA, and VIA which have
P
a positive P, i. e. a longer atomic radius than rheniums
Ti, Zr, Nb, Ta, Mo and W. Metals of the same groups with a
siialler atomic radius than that of Re (i.e. V and Cr) do not
form this phase. It would be incorrect to maintain that the
existance and the stability of the -phases is determined
merely by P. Also the effect of ele'cronic concentration must
be taken into account. in several systems the (1-phases exist
together with the ~-phases. This makes possible the observa--
tion of a certain connection between these compounds. Due to
this fact it may be pointed out that if P is near to 5%, i.e.
to a value which characterizes the difference of the inter-
atomic distances in the a-Mn-unit cell (Table 1) the tendency
to the formation of a-phases decreases, whereas the tendency
Card 2/3 to the formation of the-~-phases increases. In this connection

the authors make the following remarks concerning the nature of
the ~-phases: in the mentioned formation of the ,~-phases in binary
systems f rhenium with certain metals the double nature of the
two mentioned phases becomes manifest. They are compounds the
existence and stability of which is determined to the same degree
by P and by the rule of the electron concentration. The agree-
ment of the cheiical composition of the -~-phases with a certain
structural formula connected with the atomic radius of the compo-
nerits indicates the similarity with the Laves phases. At the same
time the ~-phases have some characteristics similar to those of
the (1-phases; their existence is however, widely connected with
the electron concentration. Thus the'~-phases occupy an inter-
mediate position between the Lav 'es and the a-phases. There are
1 figure, 2 tables, and 1? references, 11 of which are Soviet.

TITLE: On the Magnetic Structure of Chromium
FERIODICALt Doklady Akademii nauk SSSR, 1959, Vol 128, Nr 6, pp 1153-1156
(USSR)
ABSTRACT: Brief mention is first made of previous investigations made in
this field. To obtain clearer concepts concerning diffraction,
monocrystalline chromium samples were used in a purity degree
of 99.9667~. Octahedric monocryBtals (sizes of from 3 to 5 mm)
were adjusted on a two-armed goniometer of type GD-1, and lack
of blocks was controlled by X-ray structural analysis. The re-
cording took place in the planes 0(100), (110), (111), (210),
through an angle extending to 40 . Diffraction on chromium
monocrystals offers a clear picture of the splitting of the mag-
netio reflection in the (100) plane. Position and analysis of
intensity in the medium triplet peak showed that this peak is
the second order of the nuclear reflection on (200). The two
outer peaks are evidently the split 0magnetic reflection on (100).

cre4se in intensity.of.'the:split reflection peaks on (100),
while intensity of nuclear peaks and, correspondingly, those of
their second orders with an odd sum of the indices are increased
only by the Debye temperature factor (within the measuring ac-
curacy). With temperature dropping with rising intensity, also
the angular distance between the split peaks widens from 25' at
200C to 30' at -1000C. In the upper and lower critical tempera-
ture, a steep rise and an abrupt drop of intensity take place
respectively. As the curves of intensity variations take a dif-
ferent course, the existence of a temperature hysteresis of in-
tensity is very probable. The temperature range in which a mag-
netic reflection exists may be considered the range of the ex-
istenoe of an antiferromagnetic state of chromium. The tempera-
ture of antiferromWetic transformation (44 and -115") found
by the present investigation agree.with the points of.anomalous
changes of chromium properties within the error limits due to
the metal purity. Experimental results concerning the scatter-
ing of neutrons and dilatometric measurements are well repro-
ducible in different sample6 of monocrystalline' chromium. On the
whole, the results obtained agree with concepts of the magnetic
sublattice, and even supply substantial integrations leading

beyond the prevailing interpretation. The magnetic lattice of
chromium is no repetition of the crystal lattice, but is deform-
ed to a tetragonal symmetry. Certain directions are correlated
with a minimum of energy which becomes crystallographically
noticeable as a deviation of the magnetic lattice parameters
from the nuclear lattice, i.e. by a certain degree-of tetra-
gonality of the magnetic lattice. The even peaks of split re-
fldction on (100) agree with nuclear reflection as to the width,
and they have at all temperatures the same distance from the
theoretical position. The author thanks V. A. Trapeznikov for
having supplied the chromium monocrystals. There are 4 figures
and 13 references, 4 of which are Soviet.

ABSTRACT: Xn is known to be an anomalous metal with regard to combining
forces between the atomap the crystalline structure# ate.
(Refs 1,2). Active interaction with the elements of the sub-
groups IVA I VAI and VIA is typioal of rhenium. In connection
herewith, 6- and X-phases are formed in binary systems

they are analogous with regard to interaction with metals.

system for all transition metals (Ref 6). Figure I shows the
compounds formed with a corresponding transition metal in a
binary system of Mn 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 MgNi, (ZrR02. ZrMn 29T'Mn2o TaMn 29NbNn2)' All
these compounds are formed from the liquid phase and are stable
up to room temperature. It may be concluded therefrom that there
exists great similarity between Kn and Re In the formation of
alloys with transition metals. This is proved, above allp 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 structurep howeverp are formed with metals of
group VIII. In binary systems, Mn and Re form the same type of
phases with the metals of the titanium-, vanadium-9 and chromium
group, Mn and Re show a great tendency towards formation of

binary systems can not be completely classified on the basis of

similar way as Re. The comparatively d4stiact classification of
the binary systems of transition metals with Kn'and Re as well
as a restricted set of phases existing in these systems are ob-
viously related to the key position of subgroup VIII among tran-

ABSTRACT: It was the purpose of the present paper to construct the phase
diagraim of titanium-vanadium alloys and to investigate the stabili-
ty of the mstastable P-phaae within the temperature range of
-1960 -,+500 . The initial product used was Ti produced by the

processt were melted by Q,~ N. Tarasenko and 1, A. Prostovlcolla-
boratore of the VIAM ( Vsesoyuznyy nauchno-isaledovateltakiy

alloys. Alloy a with Ti produced by the magnesium-thermit process
were forged at 9000 - 9500 and gloved in vacuum. They were metallo-

and at 100 is conserved for 81 hours. Heating to 200u - 400
causes decomposition via the to-intermediate phase which gradually

is transformed into the a-phase. Heating to 5000 causes direct
decomposition in the a-phase. The decomposition of the P-phase
takes place under larger lattice constant redu ctions than in
titanium alloys with No, Pe and Ni (Refs 1, 3). The radiograph
of figure 4 shows a displacement of the P-phase lines as com-
pared to the co-phase lines, which increases together with
halting time and temperature of heating. Figure 5 shows the
deoompoeition diagram of the solid P-solution of Ti-V alloys.
The stability of the solid P-s 'olution increases with an increas-
ing V-content. The hardness test of the alloys showed the hard-
ness maximum to be within the P+ W-range. There are 5 figures,
2 tables, and 7 references, 4 of which are Soviet.
