ABSTRACT; It follcwa from general cc~nalderations that some
atoms
of an allcq which participate in the process of phase
tranefornation are in a partianlar state in which the
tran fc:~ of atoms fvam one crystal lattice to another is
probably a-ccmpanied by a temporary weakeuing of the
inter-atimia bond forces. This should bring about an
an)malius ohange of a number of phloico-chemical and
meehaxical properties of t4e alloys and if these changes
are cf suMnient magnitude , they can be detected by
known methoda of iviestigation. These anomalous effects
will apparently be of a different nature than the increase
in duotility during hardening and tempering of steel which
was cbserved earlier by Kayushnikov, F.Ya. (Ref 1) and
has al9c been investigated by Vorob'yey (Ref 2) and
Cardl/4 Golldenberg (Ref 3). Obviously, an orientated

TITLE: The Connection between Softening During Removal of Cold
Work and Temperature Softening of Nickel Alloys
PERIODICAL: Izvestiya Akadem-'! nauk SSSR, Otdeleniye

ABSTRACTz The two processes of softening appear, at first
glance, to
be unconnected processes. Alloys tested were binary
alloys of nickel with molybdenum, chromium, tungsten,
titanium, cobalt and aluminium. Chemical compositions are
given in the table. The degree of softening was followed
by measuring hardness at various stages. Samples were
given 5, 10, 25 and 38% deformation and heated to various
temperatures. The temperature of half-softening was
measured,i.e. the temperature at which the hardness was
the arithmetic mean of the cold wovked and the unworked
iiaterial. Fig 1 shown the effect of alloying content
on the half-softened temperature. With 5% deformation,
Wo Mo and Cr have the greatest effect. At higher degrees
of deformation Cr and W have the greatest effect. There
already existed data on the hardness of undeformed alloys
at various temperatures (Ref 3); from these it could be
Card 1/3 seen that the hardness test itself introduced cold
work.

The Connection between Softoning During Removal of Cold Work
and
Temperature Softening of Nickel Alloys
At higher temperatures, recrystallisation also took
place ro a characteristic bend in the hardness-
temperuture curve was obtained (the critical temperature).
Fig 2 st3vs the effect of Mo additions on the hardness -
temperature curve. Fig 3 shows the influence of
alloying elements on the critical temperature.
0.5% W or Mo and 2% Cr have a pronounced influence. Thus
an increase in critical temperature and an increase in
the half-softened temperature are both brought about by
the same alloying additions. This is because the
hardness test itself introduces cold work. Elements
which have the strongest effect are those which form
strong interatomic bonds and have the greatest values
for heat of self-diffusion. The relation between the
critical temperature and the temperature of half-softening
is shown in Fig 4 for Ni Mo alloys and in Fig 5 for
Ni - Cr, Ni - Ti and Ni Co alloys. There are 5 figures,

ABSTRACT: This work was presented and discussed at a seminar.
of heat treatment metallurgists of NTO Mashprom in
Sverdlovsk on December 16, 1959. In this extensivi
review paper (67 references), it is shown that existing
theories do not explain experimental data satisfactorily.
A new theory in put forward which can be formulated as
followst the motive force of the transformation is the
tendency to the formation from the austenite of
martensite with less free energy. This is not
materialized by the formation of nuclei of the
critical dimension or as a result of thermal or
mechanical stresses but as a result of synchronoits
directed group movement of atoms due to thermal
fluctuations. A cooperative displacement of atoMs takes
Card 1/3 place which is equivalent to that occurring under the

action of tangential stressles which exceed the critical
shear strength. It is pointed out that germination of
martensite plates in this way can occur only in the
presence of dislocation imperfections in the austenite.
If for martensite formation displacement of atoms in
required which exceeds the magnitude of elastic
displacement (for ferrous alloys)v the growth process
is similar to that of the process of sliding in the
case of plastic deformation. This determines the
independence of the speed of growth of martensite plates
on temperature. The speed of germination changes
according to a complex law under the effect of an
increase of the difference of free energies and a drop
in the probability of the cooperative shift with
increasing supercooling. Depending on the location of
the curves (probability of combined slip, slip energy
and difference of the free energies), a thermal,

TEXT: The object of the present investigation was to
explore the possibilities of replacing expensive alloy steels of
the ZoxrCA (30KhGSA) type with suitably heat-treated, unalloyed,
low-carbon steels 11101t and "15", whose composition is given
below.

Low-Carbon Unalloyed Steels as a Substitute for Certain High-
Strength Alloy Steels
To this end, the effect of hardening (quenching) temper--turo,
temperature of the quenching medium (8-109% aqueous solution of
sodium hydroxide), and tempering temperature on the U.T.S., 0.21%
proof stress (aO.2), reduction of area (~), elongation (6),
impact
strength (ak), fatigue strength, and microstructure of these
steels, was studied, the mechanical tests having been conducted
at
temperatures varying between 20 and 500*C (-70 and 500*C in the
case of a ). The following oonclusions were reached. (1) Increa-
sing the temperature of the quenching medium from 0 to 50*C,
brings
about a considerable (approximately 70%) increase in a of steels
10 and 15, but does not affect any of the other prope;ties. (2)
The best combination of mechanical properties is obtained by
quenching from 900-930*C and tempering at 300-350*C. Steel 15,
tempered at 300*C, had U.T.S. -_ 120 ~g/mm2, 00.2 = 100 kg/mm2
6 - 11%, ~ = 38%, and ak = 11 kgm/cm . This treatment also
lowered
the temperature of the ductile-V brittle transition to below
-70*C.

(3) The different response of steels studied to various heat
tr9atments is associated with their different carbon and
aluminium
contents and reflected in the micro-structure of these steels
whl6h~lis finely crystalline in the case of Steel 10, and
coarsely
crystalline in the case of Steel 15- (4) Hardened and tempered
Steels 10 and 15 display best combination of mechanical
properties
at temperatures above 300*C. (5) Heat-treated Steels 10 and 15
have U.T.S. equal to, and ~, 6, and ak higher than, those of
similarly treated steel 30KhGSA. The fatigue limit of hardened
Steel 15 amounts to 41 kg/mm2 and is 14% lower than that of
steel
30KhGSA. (6) Subject to receiving suitable heat treatment,
Steels 10 and 15 can be used in many applications as a
substitute
for high-strength alloy steels. There are 8 figures, 2 tables
and 5 Soviet references.

TITLE: Kinetic and geometrical characteristics of the
martensite transformation in an iron-nickel-manganess
alloy
PERIODICAL: Metallovedeniye i termicheskaya obrabotka metallov,
no. 11, 1961, 12-19 (+ I plate)
TEXTt In previous work (Ref.li M.Ye. Blanter, Metallovedeniye
i termicheakaya obrabotka metallov, no.4, 1960) the first of the
present authors examined reasons for the rate of growth of
martensite crystals in iron Alloys being independent of
temperature,
whereas the rate of nucleation should generally follow a curve with
a maximum. He showed (Ref-33 M-Ye- Blanter, Metodika
issledovaniya metallov i obrabotka opytnykh dannykh,
Metallurgizdat, 1952) that a proposed method (Ref.2: G.V.Kurdyumov,
O.P. Maksimova and T.V. Tagunova, Problemy metallovedeniya i
fLziki metallov, 2nd issue, Metallurgizdat, 1951) for calculating
the activation energy was unsatisfactory. The present authors

have investigated the effect of temperature and degree of
transformation on the rate of appearance of contras and the
sizes
of martensite crystals in iron alloys under purely isothermal
transformation conditions. From the relations obtained the
activation energy and the work of formation of
martensite-crystal
nuclei were found. The data obtainod confirm the dialocational
nature of the martensite transformation. The authors point out
that for the purely isothermal transformation it in practically
impossible to count the number of crystals in the plane of the
polished section. However, the thickness, a, of martensite
crystals can be quantitatively determined. Taking the martensite
crystal to be a flat parallelipiped (in principle any shape
would
do) of sides a, b, b, the number of crystals, N, formed in a
given time interval in given byt

random intercepts. The errors in determinations of a and the
volume of the martensite phase woro'5%, and 1.2-1.4% respectively.
The isothermal transformation was investigated on an iron alloy
with 23-02% Ni and 3.35 Hn. The results cannot be extended to
other iron alloys, especially steels, where the isothermal
martensite transformation is practically absent. on cooling in
air from 1200 OC the martensite point in at 10 OC, subsequent
cooling in liquid nitrogen producing 72% martensite. To obtain
a purely isothermal transformation, specimens sealed in quartz
capsules were cooled with the furnace to room temperature in
3 hours. Stabilization of the austenite reduced the transforma-
tion temperatures, and the extent of transformation was limited
to about 25% martensite, The investigation was carried out at
temperatures of -55, -68, -94, -114, -129,and -155 OC- It was
found that the temperature dependence of the rate of nucleation
in represented by a curve with a maximum. The absolute value of
the rate, n, falls continuously and progressively an the degree
of transformation risen, reaching zero when transformation in
complete. The authors attribute such a variation of n to the

dislocational nature of the martensite transformation: as direct
evidence of this they give the fact that the number K of
particles or volumes participating in the transformation 109 in
close to the number of dislocations reported by other workers

value falls from 4670 at -50 OC to 2360 Cal/g.atom at -?;5 OC.
The thickness, length and volume of martensite crystals are
practically independent of temperature, being entirely governed by
degree of transformation. At the completion of the transformation
the decrease in the thickness and length reaches 15-18%, due to
change in the state and decrease in the volumes of untransformed
austenite.

no effect on the transformation rate. This is due to the peculiar
effect
of Or on the position of A3 temperature.and hence on the difference
of free
energy values of c4-~-~-phases. 2) An adclition of Or extremely
increases
the stability of supercooled austenite in the upper temperature
range near
the martensite point- 3) An addition of Cr decreases the martensite
trans-
formation range. The isothermic transformation time of austenite
into mar-
tensite is not clearly connected with the alloy composition. 4) The
struc-
ture formation during supercooled austenite transformation in
carbon-free
allots is either by diffusion and a resulting grainy structure, or
by the
martensitio proceS3 with a resulting acioular structure. It may be
assumed
that drop ferrite forms as in the following. When acicular alpha
structure
is forming below the recrystallization threshold of austenite but
above the
ferrite threshold - the diffusion process of alpha recrystallization
leads
to a breaking up of the martensite "needles". Thus, the so-called
"droplet"
ferrite forms from acioular structures in cQnnection with subsequent
recrys-_
tallization after transformation,.because the temperature threshold
of fer-
rite reorystallization is lower than the threshold of austenite.

CrCZAS-15'(Stall 15). Th specimens were not of the usual L

the anape of a truneat:d cone (90 mm high, lower diameter 25

the speoimens
were out in half along the axis and polished, and the V!ckers

cone. Cylinders with a diameter of 8-20 mm and a
height-lo-diameter ratio
of 4 were out from the same stools. After quenching, the
cylInders were
out perpendicular to the axis, and the radial ohange of the
Vickers hardness
was investigated. It follows the equation H w A + Bx2', X i's
the distance

from the cylinder center; A and B are coefficients (see
Table), From the
relations mentioned it is possible to calculate the values of
x and X1 fnr
which the rate of cooling is equal. It is thus possible to
caloulate the
hardness of a cylinder by determining the hardness on a
conical specimen.
The relation holds for any steel. since the criterion of equal
hardness
virtually corresponds to the same rate of cooling,. A
nomograph was drawn
for the relation (Fig.). An example is calculated to
illustrate the mode
of operation. There are 5 figures, 2 tables, and 2 Soviet

'ABSTRACT: The paper describes'aii experlmental investigation of
the oxidation of
Ti which apparently is affected both by the antecedent treatment of
specimens (rol-
ling, vacuum anneal, etc.) and by the different purities of the
metal employed. The
specimens used were prepared from Ti sponge TG-00, pressed into
electrodes
which were melted in a vacuum arc furnace. The ingots obtained were
machined to
achieve a pure surface and were hammer-forged to a thickness 'of 20
mm,'hot-rolled
to 2-mm thickness, and annealed for 30 min at'7000 in an electric
chamber furnace.
Scale was removed by etching in a fusion of NaOH and NaN03;
reaction products
were removed by H7SOt. Cold rolling to 1-mm thickness and cutting
to lOxl4-mm
specimens followed. 3 -min vacuum anneal at 10- mm Hg at 600, 700,

"superhardening" pro-
11duced by the combined-treatment method may vM in nature: if
a nonsupersaturated
isolid solution is being plastically deformed: the principal
reason for its harden-
ling is the cumulation of geometrical defects of the
structure, whereas in the case
iof a supersaturated solid solution the hardening is mainly
attributable to the seg-
regation of carbon from that solution. And of coursep the
segregation of disperse
particles is the main reason for hardening in the case of the
aging of iron follow-
~in~3 plastic deformation (ease 2) and without -that
deformntion (case 3). The in-
~vestigation of the combined methods of treatment on the
basia of quRlitatlve theo-

practical importance but also

ABSTRACT: The effect of mechahothermal treatment, i.e. plastic
deformation at room
temperature, and subsequent heat treatment on the mechanical
properties of 45 carbon
!
steel has been investigated. Steel specimens, 1 x 9 x 100 mm, heat
treated to vari-
ous structures (granular, pearlite, troostite-sorbite, or
martensite) were cold rolled
1with 10, 30 or 50% reduction, rapidly heated to 8000 900, 1000 or
1100C, and water
quenched. This was followed by tempering at 200C. It was found that
the strength
iof specimens rolled with 50% reduction increased with the increase
of annealing tem-
1perature from 800 to 900C. For instance, the tensile strength of
specimens wit a
pearlitic structure increased from 210 to 245 kg/mm , and those with
a troostite-
1 2
,sorbite structure, to 225 kg/=2, at an elongation of 4% in both
cases. Further
:increases in temperature to 1100C decreased the tensile and yield
strengths and

elongation dropped to 1%. The incisase of reductions at first
lowers the strength
characteristics then, starting from 102 to 502 reduction, the
characteristics ineraasal
steadily. Thus, the steel strength can be improved under certain
predetermined con-
ditions of plastic deformation and subsequent hardening V~th a
