Belov -700 the speed of the process can be measured
and approaches !oiro Ln many cases at the tempera-
ture of liquid nitrogen. It, therefore, seemed
possible to supercool auatmite below the martensite
point and see how the transformation speed varied
vith temperature. Preaent paper gives results
of such experiments. Authors also propound
equations representing kinetics of the process.

Stable and metastable modification of martensite phases in
solid solutions can occur in "no-,Mal" or in marten3ite
kinetics. The martensite phase may be stabl.e modifications
of solid solutions or of pure me~;als, e.g., martensite of
non-carbon alloys of iron, alpha--modificatlon of cobalt,
and occasionally of zirconium and titanium.

Preliminary data touching on the Influence of carbon on the self-diffusion of gama-
iron was obtained during the investigation of the self-diffusion of pure iron. It
was sho-rm that the addn of carbon strongly influences the parameters governing the
self-diffusion of iron. Current article subjects this problem to a special Study.
Concludes that the addn of carbon in iron decreases the enera of t7ne bond of the
austenite lattice. %bmitted 12 July 51.

Abstract 11lie martensite behavior of transition of a solid solution duringr
drawing of steel can be separated into two types. A new phase
without 3tress relief and typified by microBtructure occurs an
consequence of the martensite formation mechanism. The other
type consists in a diffusionless transition of martensite with
structural changes of alpha-pha3e crystals in microspaces.

Title t The nature of coercive force changes during the tempering of hardened low-
carbon steel
Periodical : Dok. AN SSSR 98/3, 385-387, Sep 21, 1954
Abstract : The three factors playing an important role in the intensive development of
coercive for(i:3s, during hardening of stet~l, are listed. It was established
that the Martensite conversion raschanism in itself leads to considerable in-
crease in coercive force as result of tha originating internal hammering.
The effect of other factors on thin changa in coerciv6 force, during the tem-
pering'of low-carbon steel, is explained. Experimental results -show that
tempering., at 2200 results in lesser increase in coercive force than harden-

Title Binding forces and distortions in martensite crystals
Periodical Zhur. tekh. fiz., 25,"February 1955, 177-181
Abstract The essence of tempering of steel consists in the formation of
supersaturated solid solution of carbon in the alpha phase (mar-
tensite) as a result of diffusionless conversion of austenite, the
considerable change in the steel's properties as a result of tem-
pering being due mainly to those changes in the state of -the alpha-
phase lattice which cause the presence in it of carbon a,.-.oms dis-
tributed among the iron atoms; therefore for an understanding of
the nature of the properties of martenzite and their variations :n
the annealing process it is important to know the characteriotllc~;
of the structure of Its lattice, hence binding forces and distor-
tions. The authors conclude that the great resiGtence of marten-
site crystals to plastic deformation cannot be due to variation in
the binding forces in the lattice, since it is not only not h1oher
than in alpha-iron crystals but even significantly lower; and that

the cause for the hieh elastic limit of deformation in annealed
steel is the greater ttatic dit-ttortion of the martensite lattice

TITLE The Influence exeroiaed by the Interior Structure of the Austenite
Grain on Strength at Increa.ied Temperature.
PERIODICAL Dokl. Akad. Nauk, j02, fasc.1, 65-87 (1956)
Publ- 7 / 1956 reviewed 9 / 1956
In the present work a solid solution on an iron base containing about 29%
nickel and 1% titanium is examined. The direct martensite transformation of
this alloy takes place below room temperature, but the inverse transformation
0 0
ceases at 640 . The samples were homogenized for 8 hours at 1000 after
melting and forging. After the aforementioned treatment the samples had
austenite structure, and their state depends on working temperature. The en-
durance strength was tested at 700 0 in an argon atmosphere by tension. An a
result, the dependence of endurance strani3th on the connected tension and on
the temperature during preliminary treatment is obtained, and herefrom also
the tensions necessary for a fracture of the sample after 100 hours. Further-
more, short testa of breaking strength were carried out at 7000, on which
occasion the following results were obtained: The higher the temperature of
annealing after the martensite transformation, the lower is the strength
limit and the larger the endurance limit of stress, i.e. the tension necess.-
ary to bring about a fracture after 100 hours.
X-ray examination supplied information concerning the atate of the crystals

of the solid solution after corresponding treatment. Some X-ray pictuxes
ta)(_ rih-manganese radiation are attached; they permit a qualitative de-
scription of the state of the crystal lattice of the austenite after an in-
verse martensite transformation and following heating. The broadening of the
lines in a radial direction is due to tensions of the 2. kind, and to thei re-
duotion of the domains of the coherent scattering of X-ray radiation. Tho de-
scription of the interference spot in azimuthal directionindicates a mutual(?)
or opposite (?) rotation of these domains. These states of the crystals (grain)
of the solid solution are conserved up to very high tem 9eratures and recrystal-
lization begins only at 10000. After annealing at 1100 and 12000 reflections
of new recrystallized grains become noticeable. Each austenite grain is a
total of small domains with a proper crystal lattice, and this lattice is
interrupted at the boundaries of the grain. The higher the annealing tempera-
ture after the inverse martensite transformation, the more completely will the
destructions of the crystal lattice be removed, and the more will the 3trength
of the solid solution be reduced. At high temperatures and low tensions a
treatment that removes (or increases) defects of the lattice will increase
(or deteriorate" resistance against plastic deformation,

TITLE On the Hardening of Not Alloyed Carbonless Iron.
PERIODICAL Dokl.Akad.Nauk, L11, fasc-4, 818-820 (1956)
Issued: I / 1957
At first some previous works are discussed. The impossibility of hardening
carbonless iron, i.e. the impossibility of the production and the growth of
the germE of the a-phase above the martensite point is due to a disturbance
of the oryjtal structure of austenite, and consequently by the high mobility
of the atoms. Heating up to 10000 and more diminishes the production velocity
of the a-phase in a higher range of transformation temperatures and makes
undercooling of the austenite down to the domain of martensite transformation
possible. If these assumptions are correct the possibility of hardening pure
iron by increasing the temperature of heating will increase. For this purpose
a heating temperature of more than 11000 is taken, because in that case the
dependence of the diffusion coefficient on temperature takes a normal course.
The iron examined in this case had the following chemical

annealed at 6000 80 H. was obtained for hardness, and for the breadth of the
line (220) 9.10_~ radian was 0obtained in iron radiation. After hardening of
the samples from 980 to 1020 , hardness increasod to 100 - 120 11V. The inter-
ference lines were somewhat washed-out on this occasion, but the doublet Ka
of the line (220) did not fuse completely. In the course of hardening which
proceeded from 13500, hardness amounted to from 190 to 210 HV, and the doublet
Ka fused into a broad line.
The data at present available concerning the strength and the roentgen proper-
ties of carbonless iron show that the solidification attainable by martenaite
transformation has a similar strength as solidification attainable by cold
plastic transformation. By comparing the resulta of chilling and cold deforma-
tion of iron it is possible to conclude that on the occasion of chilling pro-
ceeding from 13500, the traiasition J'--:> a (at least with respect to the
greater part of the volume), takes place according to the martensite mechanism.
However, chilling proceeding from 10000 caused only partial hardening. A pos-
sibility of undercooling the r -phase of iron (and therefore its hardening
properties) depencb largely on the inner structure of the grain and on the
quality of the crystal structure.

Depending on the nature of ttie alloyin~~ elerjent,the bond
forces can be increased or decreased. Earlier work of the
authors (3) and of Iveronova, V.I. and Katsnellson, A.A.(4)
have shown that the concentration of the alloying component
is also of great importance, the heat treatment and Dlastic
deformation was also found to influence the characteristic
temperature of the solid solution (2,3,5,6). In recent
years a considerable arjount of viofk has buen published

be considered as an established fact that certain properties
of the solid solution can be chan-ed sp:)reciablyby heat
treatment and deformation without cny change occurring in
the chemical composition of the investigated -ohase; this
phenomenon (change in the characteristic temperaL;ures,
electrical resistance anomalies, change of the lattice
period etc.) was detected only in solid solutions but not
in pure metals. Analysis of results of otder authors
permits the assumption that the anomalies in the properties
observed by various authors can be attributed to a general
cause and are the result of the same process taking place
inside very small volumes of the crjstal lattice of the
solid solution. The most likely assumption is that the
observed anomalies in the properties are due to changes in
the distribution of the atoms in the lattice of -the solid
solution and on that numerous authors are in agreement
but, on -the other hand, various authors disaorce on the

influence was investigated of differing treatments on the
interatomic interaction in crystals of solid solutions and
of some high melting point metals and the influence was
studied of the plastic deformation and heat treptment on
the bond forces. The investigations viere effected by X-ray
methods and by measuring the resonance frequency of the
lonEitudinal elastic oscillations (determination of the
modulus of elasticity). The investigations were carried out
on iron alloyed with chromium, manganese, W, Ni, Ti and
also on pure Cr, 17 and Tn. For meltinG the metals a 50 kg
capacity high.11,equency furnace was used and -U'-Iie material was
cast in-to 25 kg ingots. The ingots were subjecued to
diffusion annealing at 1200 C and then forged into a square
of 40 x 40 mm cross section and into rods of 15 mm dia.
Forging was begun at 1000 to 1100 C and,after forginG 'the
material was cold rolled with a total reduction of 62.5%,
-the specimens for determininS the modulus of elasticity
were cut from the rolled strip in the direction of rolling
and were 100 mm long and 10 mm dia. Tho chem-ical analyses

pure metals Cr, W, Ta and also for the YounG modulus of
iron and the alloys Fe-Ni, Fe-W, Fe-Cr, Fe-Iln after various
types of heat treatment. It was found that the character-
istic temperature of the pure metals Fe, Mo, V1 and Ta does
not change after heat -treatment and deformation of these
metals. In chromium an increase was observed in the
characteristic temperature after heatinE deformed specimens
to 600 C; after heating deformed chromium ut 800 C its
characteristic temperature did not chauEe; it was found that
the effect of changes in the characteristic temperature as
a function of the heating temperature is reversible. There
is a bond force during heat treatment and deformation of the
solid solutions Fe-Cr, Fe-W and Fe-h1n: the characteristic
temperature increases on heatingwithin a given temperature
range and decreases as a result of plastic deformation and
hardening (Fe-Cr, Fe-Mn). It was established that there is
full correspondence between the direction of the change in
card 5 the characteristic temperature and the Young moduUq, resulting
from heat treatment and workino of the solid solutions

AB8TRACT: Determination of the static distortions of the crystal
lattice (third order distortions) is usually effected
by comparing the absolute or the relative intensities
of X-ray reflections from equal crystalloFraphic planes
of deformed and of annealed metal. It is thereby assumed
that a change in the intensity should be due solely to
one cause 7namely, the existence of a disordered
distribution of the dis lacements in the deformed
specimens. The second Mnealed) specimen is used as
a standard. The preliminary heat treatment of this
specimen must be so carried out that there should not
be an intensive coarsening of the crystal structure which
would lead to a weakening of the intensity of X-ray
reflections (extinction). In order to determine the
nnealing temperature of deformed iron povider at which

extinction takes place, the followinG experiments were
made: defor;4ed iron powder was annealed at 500, 650,
700 and 750'JC. These powders were used for producing
cylindrical specimens of 0.9 mm dia. The X-ray
investigation was effected using molybdenum radiation.
The X-ray patterns viere photometrically evaluated by
means of a recording micro-photometer which recorded the
curve of intensity distribution on a self-recording
electron potentiometer. Each half of the radiograph
was photometered twice. The intensity was determined
of X-ray interferences from crystallographic planes
with the following sums of the square values of the
indices: 6 14 26 62 Obtained experimental data
are entereA in'Table 1: After annealing at 500 and ?OOoC
-the relative intensity of all the measured interfegence
values did not change; only after annealing at 750 C was
a weakening observed of the intensity of the X-ray
reflections from the planes (211) and (321). The

the effect of 'the extinction for the various crystallo-
graphic planes is graphed. The effect of extinction
was also studied in a solid specimen. One of the
investigated specimens of hardenSd iron was tempered
successively at 450, 550 and 600 C for two hour s and
the intensities viere measured of the X-ray reflections
from the planes with the sum of the square values of
the indices 61, 141 26 and 62 and in the hardened state
161 141 26. The experimental results arc ontered in
Table 2. It can be seen that the effect of extinction
in a solid opecimen of hard8ned iron manifests itself
even after tempering at 600 C. It can also be seen
that type III distortions do not occur during
hardening.

ABSTRACT: In earlier work (1 and 2) the authors have shown that at
sufficiently low temperatures the speed of martensitic
transformations is measurable. Researches carried out by the
present authors indicate that in some steels with a low
martensitic point T (temperature at which martensitic
transformation beginW ) the transformation of austenite
into martensite can be completely halted by rapid cooling
in liquid nitrogen, and isothermal transformation of
austenite into martensite can be observed at temperatures
above thia boiling point of liquid nitrogen (3 and 4).
It was shown that a definite energy of thermal vibrations of
atoms is necessary for the formation of martensite nuclei,
At insufficient energy the speed of formation of nuclei is
practically zeroi as the enerSy of vibrations increases the
