TITLE The Decay of a Solid. Solution in Thin Plates.
PERIODICAL Dokl. Akad. Nauk, 108, 841-842 (1956)
Publ. 6 / 1956 'reviewed 8 / 1956
According to K.N.BUJNOV and R.M.LERIM, Izv.Akad.Nauk. SSRp Ser.fis.No 3,
363 (1951) the decay of a solid solution probably takes a different course from
a certain critical depth onwards than in thick samples. In order to find this
out, the temperature dependence of the decay of a solid solution of Ou in Al
was investigated in samples of OA; 0,02 and 0,004 mm thickness. After quench-
ing, the plate-shaped samples we;re annealed for one hour at 180,200,220,
... 3000. The decay process was radiographically analyzed from the modification
of the lattice constant of the p,rimary solid solution. Not only in eamplija of
0,004 mm thickness, but also in such as are 0002 mm thick, decay develops in
a different manner than in 0,4 mm samples. Domains with different degrees of
oversaturation exist in samples of 0,02 and 0,004 am thickness after tempering
at 260 and 2600 . After tempering at 2600 (or 2800) crystal domains with a
concentration similar to the initial concentration (i.e. with equilibrium
concentration) predominate. In the samples Of OP4 mm thickness tempering at
260 and 2800 causes homogeneous decay, on which occasion the lattice constant
changes steadily. If temperature! is further increased, the solid solution has
a uniform concentration at all thicknesses from OtOO4 to 0,4 mm within the en-
tire domain, and the lattice constant diminishes by the increase of solubility.

ABSTRACT. Fe-V alloys at temperatures above 1 234 0C form a solid
solution a with a cubic face-centred lattice. Below this
temperature the solid solution decays and a a phase with the
0 - U structure havirig 30 atoms~per unit Sell separates. An
alloy of 2636 V in Fe was annealed at 975 C and decayed to the
two phases. Monocrystalline specimens, prepared by heating for
60 hours at 1 350 'C and quenching in-water were used for X-ray
examination. Specimens of 1 am dia. were thus converted to
singlo crystals and ivere cut up for examination. Laue phgto-
graphs were taken after different annealing times at 975 'C-
For times of 1-30 hours no changes were evident. After 40
hours.spots showed that the nuclei of the a phase were
oriented parallel to the 001 plane of the a phase. After

ABSTRACT: The investigation of the transformation y4y+(x in
an alloy of iron with 32% nickel by the methods of X-ray and
microscopic analysis showed that the initial stage proceeds
following the martensitic type of transformation scheme. In
this the layers of the a-phase are oriented parallel to the 111
plane of the y-phase. Because o; the low value of the elastic
limit of the Fe-Ni alloys at 400 0, the coherence of the
lattices of the y- and a-phases is destroyed in the initial
stages of the transformation and the further growth of the
nuclei of the a-phase proceeds by diffusion. In the matrix
round the nuclei a zone of plastic deformation is formed
clearly distinguishable under microscopic investigation,

fact -that much work has been done on the problem of

extremo stability of the nori-equilibriwa state in these

to isothermal annealing at 400 C. The X-ray patterns were
photographed using iron radiation in cameras of 114 cm dia;
the spScimen dia. equalled 0.4 mm. It was established that
at 400 C the transformation is very slow. Deformation of
the alloys at room temperature does not only accelerate
the process of y to a transformation; deformation of an
alloy a6ter being subjected to martensite transformation
at -196 C will accelerate also the reverse y to a trans-

ABSTRACT: Though there is a domain of the I-phase in the state
diagrams of the alloys in question which passes over into
the domain of salid solutions of the a-phase at > 12340C
for Fe-V-alloys and at 8200C for Fe-Cr-alloys, these trans-
formations are assumed to be more complicated, because
these alloys aria transformed rapidly in the single-phase
region of the cr.- as well as of the a-phase. Thus the
brittleness occurs very obviously after annealing at
400-5500C in these alloys that belong to the aingle-phase
region. The plasticity is here reduced to stro, by this
their practical applicability is restricted. According to
references 3 and 4 a solid solution rich in chromium is
Card 1/4 assumed to precipitate at low annealing temperatures. An

modification of the properties which does not correspond to
the single-phase structure of the solid solution was
observed also above the transformation temperature from
a- into the a-phase (ref. 6,7)- It is difficult to be
explained by the! atomic regulation which is assumed at low
as well as at high temperatures by several authors (ref 7).
In the present paper the structure of the alloys in
question was to be investigated after a heating between
1400 and 6000C with quenching in water. The investigation
was carried out by means of X-ray diffraction methods in
the polycrystal and by means of microscopical analysis, The
alloys were homogenized after casting at 13000C from 20 to
100 hours and iramediately afterwards quenched in water.

the powder obtained by mcans of a file were ta~ken with a

alloys are (with a vanadium content of 28,5-74 %) not
single-phase, but two-phase. It was proved mier,3stopi-cally

(hardness- 250 kg/mR2) crystals of another phase with a
hardness three times greater than the first mentioned
become visible. The content of this last phase increases
with increasing vanadium content. The radiograph confirmed
this: 2 systems of lines appear on it. The other phase is
denoted as P-phase by the authors. The content of the
phases was detennined in the case of different vanadium
contents. The two phases still existed at temperatures
above 1150*C. I-a the case of annealing at 8000C the alloy
with V-content of 28,5 ~ consists of the (x-phase only. From
43 % V on it consists of a- and-Y-phaze. In the case of
annealing at 600:C and 49,5 % V it consists of the O'-phase
only. Thus the course of the phase transformations in more
complicated at a vanadium content of 28,5-74 % between 1400
and 6009C, than described by the phase diagram in

ABSTRACT: The deterioration of the properties of Fe-V alloys which
follows the separation of the a-phase on cooling has
attracted consideriable attention. In the present work an
investigation was made of the atructure of alloys of Fe
with 27 and 47.7 weight % V after annealing followed by
hardening from various temperatures. X-ray and
microscopic analysis and measurement of magnetic
properties were used. Both alloys were found to have a
two-phase structure, the quantity of second phase bei.'ag
greater for a 1400 than a 1250 OC hardening temperature.
The magnetic properties likewise indicate (Figs 1 and 2
show these as functions of teaperature for various
conditions), that the two-phase is the equilibrium
structure at teaperatures above the a-a transition point.
Card X-ray analysis pointed to the existence of a new phase,

The quantity of a-phatio in the 47.7 and 27% V alloy
was found by Nechvolodov's method to be 35 and 10%
respectively. The magnetic properties of the low- and

composition of the P phase in the alloy with 30. Ylo tin is dealt
with. In these investications, the phase transformations are
inferred from the location of the diffraction maxima. For ex-
imple, the diffl:laction pictures (Pigs 2 and 4) of the alloy
with 27.ep tin, taken at various time intervals after the therm-
al treatment, are shown, and the progressive phase transforma-
'tion is investigated thereon. The eutectic transformation is
investigated in the same way and described with a number of

role of individual factors in alloy hardening is not
clear. They report their investigation of the

used. X_ra~Cinvestigations showed that by quenching
from 1 100 an austenite structure is obtained but
tempering at 750 0C for 12 minutes gives rise to diffuse
lines of carbides, further carbide lines appearing on
prolonging tempering. At 750 0C, however, these remain
weak. The qurie point of carbide in the steel rises from

TEXT: The authors maintain that in spite of the numerous
investigations of the eutectoidal transformation its initial
stages need further study. They report their work on the
transformation in a steel with 125'0 Mn and 1.2% C and one with
1.77% Ma and 2% C, using X-ray analysis of poly-and single
crystals. For the 12% Mn steel the investigation was carried
out after tempering at 670 OC. The authors discuss the
/patterns obtained and calculate stresses, crystal size and
~blatt_ice deformations. Fig. I shows the pattern from a single
crystal after hardening and tempering for 3 minutes; Figs. 2
and 3 after tempering for 14 and 40 minutes, respectively. A
conclusion trom the results is that the sequence of alpha--
phase liberation is different at the same temperature in a AS

TEXT: The of aluminium-zinc alloys of single and polycrystals

The starting materials were AB 000 (AVOOO)Nluminium and 99.8% pure
zinc. The single crystals were prepare by slowly cooling melts of
the alloy. Fig.1 shows an X-ray photograph of a single crystal of
aluminium - 10% zinc alloy after natural ageing. The presence of
streaks indicates the formation of areas rich in zinc. Single
crystals and coarse grained alloys were also polished
electrolytically and chemically etched. Etch figures increased
with increase of zinc content from 5 to 15%- After two days ageing
at room temperature, the etch--figuves were uniformly distributed
within the grains. After five days natural ageing in individual
crystals of the aluminium-10% zinc alloy, the etch figures were
arranged in parallel lines (Fig.2). The uniformity of the etch

figures depended on the orientation of the grains and the time of
ageing. After seven months ageing, theletch figures were
distributed uniformly in all the 4ELinsItforming a network with an
angle of 70* After 50 hours ageing at 1509C, spots appear
on the Debye rings corresponding to (311) reflections. After
255 houra, the intensity of these spots sharply increases and
streaks appear in a radial direction across the Laue maxima.
After 320 hours the intensity and angular length sharply decreases
(Fig.5). This effect is caused by the reorientation of small
volumes of the matrix as a result of differences in the specific
volumes of the matrix and the precipitating planes. There are
5 figures-and 2 Soviet references.

thermal sections at these tva ta=erttures of the phase diagram of the Mo-Ti-Zr 57B-
tam were constructed. A sizable region of a A solid solution, extending continuously,
from the Mo-Ti system to the Ti-Zr system and bounded by a region of heterogeneous
state of the alloys on the side of the Mo-Zr system, was found in the section at 600*0
(see Fig. 1). The region of heterogeneous state of the alloys occupies SL small vart
of the concentration triangle mid protrudes t(reard the titanium cornor (see ~vig. I).
Unmixing of the 0 solid solution into two solid solutions occurs at = oquiatomic
content of Mo in Zr and 61 at. % U. Two three-phase regions, Al + 9~2 + 6 and a +
92 + 6,exist inaside the haterogensoms region. The 6 phase extends up to 13 at. % Ti

TEXT: An investigation was made of the structure of single
,crystals of alloys of copper with 27.8 and 25-5 wtO; of tin,
together with hardness determinations on polycrystalline specimens
(27.8 wt.% Sn) both after hardening and'during natural ageing.
The microhardness of the polycrystalline specimens increased'from
200 to 450 kg/mm2 during two years of ageing. To elucidate
structural changes causing this increahe in hardness, three
single crystals with 27.8 wt.% Sn.and one with 25-5 wt.% Sn .were
examined after ageing for 40 days, 8 months and 3 years. The
single crystals were prepared by a slow crystallization from the
melt followed by a homogenizing treatment-at.600 *C for 26 hours.
Mixed and monochromatic Mo radiation were u3ed-for the X-ray
studies. The results obtained indicated that during natural

stresses. 2) Single-crystal specimens, prepared by slow
(10 OC/h) cooling of the melt0in the crucible and quenched (with
thecrucible).on reaching 870 C, had a structure which depended
on the rate of cooling during quenching. Specimens quenched in
porcelain crucibles consisted of the y-phase; those quenched in
a graphite crucible constituted single crystals of a metastable
phase with a face-centred cubic lattice; air-cooling of a single
crystal produced by the pulling-out technique resulted in the
y-phase, in which the procei3s of precipitation of the a-phase had
begun- 3) Slip on the (110) and (112) planes took place in'
water-quenched, single-crystal specimens; This was accompanied
by the formation of atom aggregates with destroyed periodicity
which, on subsequent ageing, became crystals of the a-phase,
oriented in accordance with the principle of structural conformity.

TEXT: The change in the block structure of the matrices %ith phase
transformations 0of Al-Si and Al-Cu alloys was investigated. After being
hardened at 5500 C, single crystals of an alloy of Al with 1.2~ Si were
tempered at 218 C. The lattice constant changed' from 4.0380 to. -
4.0386 A after 10 minutes; and the block boundaries were clearly
discernible after 20 minutes. The angle of disorientation of the blocks
was measured by an X-ray reflection method. Single crystal plates vith an
area of 1 - 2 cm2 were grown in air in a furnace with a temperature gradient
of 10 degree-cm-1. The alloy had a dendrite structure immediately after
crystallization. Most of the crystals were not ideal anJ composed of ;-
relatively few blocks. After 2 min annealing at 280 0C the maxima halve,

showing that the blocks are disorientatgd by 4'. The disorientation after
5 min is 61. After an annealing at,280 C for 10 min the blocks turn, and
after 20 min the orientation of the blocks in a crystal increases.
Consequently, the formation of the second phase from a solid solution of
Si in Al causes a disorientation of the blocks. The structural changes
are irreversible. Al alloys %ith 4 per cent by volume of Cu have a band
structure under the'same crystallization conditions, and the crystals
consist of a multitude of minute blocks. After 20 min annealing at 2160C
the distance between 'some of the reflected maxima increases, while another
group of maxima remains unchanged. After annealing times of 30 - 60 min
the samples again show the sane picture as immediately after quenching.
Consequently, after the coherent bond between the newly forEled Material
and the matrix has broken, the disorientated blocks return to their
initial position. Howeverg this elastic disorientation has a local nature
and covers the total crystal volume non-uniformly. The degree of in-
homogeneity is dQtermined by the substructure of the initial crystal of
the solid solution. There are 6 figures and 4 references: 3 Soviet and
1 non-Soviet. The reference to the English-language publ 'ication reads as

ABSEACTi The effect of germanium upon the aging -of Al-Ag and Al-Cu alloys has been
inv63tigated. Methods employed in the study were x-ray analysis of the rigid nono-
crystals, oscillation and rotation, and changes in hardness. The alloys were
prepared of Al (99.9Q,6%)., Cu (99.9%).. Ag (99.9%)o and Go (99.99%) and had the
following compositionst. 1) A1-10% (by weight); Ag-2% Ge; 2) Al-4% Cu-0.4% Gej
3) Al--3% Cu-I%Ge. Decomposition of the solid solution was observed""ILfter aging

ABSTRACT: Thcaging of the suporsawratcd solid solution of Cu in Al involves the formation
of laniellar Guinier-Preston (G. P.) Zones during the pre-segregation stage; the aging of tho
solid solution of Ag in Al involves tho formation of spherical G. P. zones. In t1iis connection
the autors investigate the process of the decomposition of an Al-3 wt.% Cu-7 wtA Ag alloy
by analyzing anomalous effects on the roentgenograms of immobile monocrystals and by per-
forming an clectronmicroscopic analysis of thin, foils following their aging at 130 and 218*C.
Findings: the investigated specimens contain both lamellar and spherical G. P. zones. Fol-
If lowing 30 min of aging at 218*C the 1~hotographs made with the aid of an UEMV-100 electron
