Title The.influence of zinc concentration on the mechanical properties of a
solid solution of zinc in aluminum
Periodical Zhur. tekh. fiz. 24, 544-548, Mar 1954
-Abstract txperimentally establishes that alloying of aluminum with small amounts
of zinc reduces while larger additions of zinc improve mechanical prop-
erties of aluminum-base alloy. Suggests,two explanations for this
phenomenon: first explanation follows from studying mechanism of plas-
tic deformation in alloys with various additions of zinc; second is
based on changes in solubility of hydrogen in aluminum under effect of
alloying zinc. Twelve references, 5 USSR, 1937-1952. Diagrams.

ABSTRACT: Microscopic and x-ray methods were employed in an inves-
tigation of the effect of concentration of an alloying element on
the mechanism of plastic deformation (D) of a binary solid solu-
tion of M in Al. Alloys containing 0. 01, 0. 04, 0. 10, 0. 30,
and 0. 92~6'Mg were studied. The specimens (S) were in the
form of strips having dimensions of 50x3xl. 8 mm. The grain
size in all alloys was 0. 01 mm. After electropolishing, the
annealed S' s were stretched in a machine at a rate of 0. 2%/
sec at temperatures of -193, + 18, and + 2500C. In addition,
at 2501, all S' s were subjected to creep tests at rates of
2-4xlo-30/o/hr. As a result of investigations of two degrees

established that the employment of Mg as an alloying element results in a
more uniform distribution of slip D in Al grains. As the Mg content is
increased, the spacing between slip traces decreases together with the
magnitude of the shear in the slip traces. Within the investigated interval
of temperatures, the D, carried out at a rate of 0. 20/0/sec, produced
crumbling of grains into disoriented zones of three different sizes. The ex-
.tent of disorientation of such zones attains a magnitude of 10301 and is very
stable. As the Mg content is increased, disoriented zones appear in
regions included into deformation strips. High- temperature plastic D is
accompanied by slipping along grain boundaries; the magnitude of the slipping
decreases nonmonotously with increasing Mg content in the alloy and attains
a minimum when the Mg content is 0. 10/6. The hardening of the Al, result-
ing from the appearance of Mg atoms in the alloy, is explained by the follow-
ing factors: a more complete inclusion of the entire volume of metal grains
into the D process; increased magnitude of heterogeneous stresses within
grains producing fragmentation of grains into strongly disoriented zones and
intensification of processes of rising diffusion resulting in relaxation of the
stresses in the grains; a reduction in the mobility of lattice distortions owing
to the formation of clouds of Mg atoms in the vicinity of the dislocations. V. N.

in the temperature and a decrease in tne speed of deformation
have the same effect. The wide range of investigations
enable them to study the transition from the glide to the
diffmion mechanism of deformation at the temperature of
250 C. It was established that the transition is gradual
and is caused by decreasing the length of the displacement
along the glide plane and increasing localised deformation
along the grain boundaries. At the lowest tensile strain
rates the deformation is accompanied by sub-division of grains
into large blocks. The observed dependence of the mechanism
of the plastic deformation on the conditions of deformation
is determined to a considerable extent by the difference in
the quantity and the character of the lattice distortions
which existed in the aluminium prior to deformation, and also
by the formation and cessation of-distortions during the
process of deformation itself. 15 figures including two

low temperatures these areas consist of slightly misorientated
blocks. The total angle of the misorientation of the blocks
for a strain of 2% does not exceed one degree. With increasing
deformation the misorientation increases aiad the block dimen-
sions decrease, reaching the order of 10-t em at a strain of
18%. At elevated temperatures the misorientated areas consist
of a small number of blocks; the total misorientation angle
at the beginning of the deformation is lower than at lower
temperatures. With increasing strains at higher rates of de-
formation the number of blocks in t e gTaans increases to some
extent and if the.speed reaches 1A%olfir the quantity of the
blocks in the grains decreases with increasing deformation
and remain unchanged when the block dimensions become equal to

ABSTRACT: Polycrystalline test-pieces in the form of strips were
manufactured from solid solutions of magnesium in
aluminium containing respectively C-.00, 0 Oil 0.041 0.10
and 0.30% magnesium. The grain size was almost constant.
Specimens of each composition were electropolished and
subjected to extensions of 2% a;id 14% 0at a rate of 0.2176
per sec at temperatures of -196~C, 18 C and 250'C, and
to Sxtensions of 2016 and 14% at 4 x 1o-3% per hour at
250 C only. The surfaces of the deformed specimens were
examined microscopically, the authors distinguishing
between straight and curved slip lines and slip bands.
The distance between slip lines was measured a~Ld
interferometric methods were used to determine the slip
Card displacement and the displacement along the grain
1/3 boundaries. With specimens extended to 2% at 0.2% per sec
the displacement in the straight slip lines was almost

constant at 0.1~L for all magnesium contents. Increase in
the magnesium content tended to decrease the distance
between slip lines. Curved slip lines occurred, evidently
at 250 C only, in alloys of magnesium contents up to 0.1%,
the displacement in them decreasing and the distance
between them increasing with increasing magnesium content.
With strong alloying deformation bands appeared. The
displacement along the grain boundaries varied in a
non-monotonic way with magnesium content having a minimum_,
at 0.1% magnesium. In specimens extended to 2% at 4 x 10
per hour no slip lines appeared. The displacement along
grain boundaries however, was again a minimum for a
magnesium content of 0.176. 14% extension produced a
coarser distribution of slip phehomena. The same general
dependence of displacement in, and separation between,
slip lines on the magnesium content was observed. Though
graphs are given for the behaviour of the curved slip lines,
Card it is stated that in this respect differences between
2/3 grains were great. Slip bands were always present; the Iir
number and the displacement in them increased with

increasing magnesium content. The grain boundary
displacement showed the same dependence on magnesium
content as in the previous cases. These observations
were explained qualitatively on the basis of the lattice
distortions produced by the presence of magnesium atoms,
it being suggested.that the distortions blocked the
progress of dislocations.

tes~ingall the alloys were 3investigated for creep at
250 C with a speed of 4-10- %/hr and a deformation
corresponding to a 2% extension. The specimens
consisted of strips of 2 x 1 x 50 mm. The investigations
were offectod by using the Laue X-ray method mid by the
optical polarisation method. The influence of magnesium
on the block formation was studied by the X-ray method
on the basis of the magnitude and the character of the
radial blurring of the Laue patterns, which were obtained
using the continuous radiation spectrum of copper, The
polarisation method enables visual observation of the
formation of deorientated sections in the grains; the
sensitivity of this method is low and the sub-structure
in the grains can be observed if the deorientation of
adjacent sections exceeds 0.5 to 10. This method was
used for studying the sub-structure occurring at the
later stageo of deformation equalling 111 to 1% Some
of the obtained Laue patterns are reproduced (Figs.1 and

SOV/126-6-2-20/34
Sub-structure of grains of deformed aluminium-magnesium alloys
It was established that alloying of aluminium with
magnesium brings about a change in the sub-structure of
the grains occurring during deformation. For all the
applied temperatures and deformation speeds, the
dimensions of the blocks which form in the regions
enclosed between the slip traces decrease with increasing
Mg content. Furthermore, the quantity and also the
degree of deorientation of large.deorientated sections
also increase. The influence of magnesium in the alloy
on the decrease of the dimensions of the sub-structure
blocks is most pronounced at high deformation temperat-arles.
The change in the number and the degree of deorientation
of the large deorientated sections can be clearly
observed at all temperatures. The refining of the blocks
of the,sub-structure is due to two causes: decrease of the
distance between the slip traces (i.e. the width of the
area where blocks occur) and decrease of the mobility of
the lattice distortions which form the block boundaries.
The decrease in themobility of the distortions can be
brought about by appearance in these of magnesium atoms.
Card 3/5 The formation of large deorientated sections in the

BOV/126-6-2-20/34
Sub-structure of Grains of Deformed Aluminium-Magnesium Alloys
grains during deformations is the consequence of non-
uniform stresses occurring in the grains due to inter-
action between grains. The increase in the quantity and
.the degree of deorientation of such sections with
-increasing magnesium content in the alloy indicates an
increase in the non-uniform stresses inside the grains.
Such an increase can take place since, according to
Green, Pavlov et alii (Ref.15), the magnesium hardens the
alloy. Furthermore, it is known that with increasing
magnesium content the grain boundaries will harden more
than the body of the grain; this brings about a reduction
of the stress relaxation at the boundaries and intensifies
the interaction of the grains. The refining of the block
structure and the growth of non-uniform stresses in the
grains with increasing magnesium content in the alloy are
to a large extent decisive from the point of view of high
coefficient of hardening of aluminium-magnesium alloys.
It is necessary to point out that qualitatively magnesium

n the grains becomes more uniform and straight-lined, the deformation along
the grain boundaries decreases. It is stated that the 8-fold decrease of the
deformation speed in Al within a temperature range of -1960 to +2500C can not
be explained by changes in the binding force, since E decreases only by a
factor of 2 in the temperature range of -1960 to +6000C. It is assumed that
the discontinuity and branching of the slip bonds at higher temperatures and
low deformation speeds are connected with an easier shifting of dislocations,
not only in the slip band but also in the direction that is perpendicular to
the latter. Rt-actionation of the grains into domains with boundaries formed
of dislocations, takes place under the effect of heterogeneous stresses, arising
In the 'grains due to their 4raction along the boundaries. Interaction of
elastic fields of dislocatiod with Mg atoms causes accumulation of the latter at
the dislocations; this reduces deformations in such spots, diminishing the
mobility of dislocations and raising the resistance to deformation of alloys.

ABSTRACT: In this report the results of an investigation of the
effect of alloying nickel with aluminium and nickel with
copper on the mechanism of deformation are given. The
compositions of the investigated alloys are, given in
the table, P 930. Nickel of 99.99% purity, which had
been remelted in vacuum, was used as the basis metal for
the preparation of the alloys. The purity of aluminium
used was 99.99%, and that of copper, 99-95%. The working
specimens were 50 x 2 x 0-3 mm in size. The specimens
were annealed so as to obtain the same grain size. The
linear grain size was 0.1 mm. The temperature of
recrystallization annealing.for pure nickel was 8006C,
and for the alloys 900-1000C, The specimens were
deformed at two temperature's and at two straining rates
The nickel-copper alloys were elongated at 4000C at F.

oxidation of the specimen surfaces, pulling was carried
out in a nitrogen atmosphere. Prior to deformation the
specimens were electropolished and etched. The conclusions
on the deformation mechanism were arrived at on the basi--
of results obtained in the microscopic study of the
deformed specimen surface, as well as from a study of the
extent and form of the radial diffuseness of X-ray
interference maxima in Laue photographs. The microscopic
study of the surface was carried out by means of the
Linnik inferferometer MII-1. The Laue picture was taken
in a white molybdenum or tungsten irradiation. Under the
above conditions of deformation the following processes
were found to take place in the alloys: 1. Shear along
slip planes. 2. Shear along grain boundaries.
3. Displacement of grain boundaries. 4. Splitting of the
,grains into blocks. These phenomena occurred after two
as well as after 12% deformation. In-this paper the
Card 2/5 results obtained with 2 P*er'cent deformation are mainly

reported. After straining by.12 per cent, the surface
relief was so coarse that quantitative measurements were
impossible. In Fig la the dependence of shear along the
grain boundaries on the composition of nickel-aluminium
alloys, and in Fig 1b the dependence of shear along the
grain boundaries on the composition of nickel-copper
alloys, at various temperatures and deformation rates,
are shown. In Fig 2 grain boundary displacement in pure
nickel at various temperatures and degrees of deformation
is shown. In Fig 3 grain displacement in nickel-
aluminium alloys, deformed by 2 per cent at 7000C is
shown. Fig 4 shows the grain displacement in nickel-
copper alloys under the same conditions. Fig 5 is an
X-ray photograph of a 0.5% aluminium alloy, deformed by
2 per cent at 7000C. The authors arrived at the
following conclusions:
1. Shear along the grain boundaries and a displacement
of boundaries occurs in nickel deformed at a high
temperature. Both processes are due to the action of
Card 3/5 stresses arising in the grain boundaries during

SOV/126-7-6-21/24
Mechanism of High Teifiperatu3~6 Deformation of Nickel-Aluminium
and Nickel-Copper Solid Solutions
deformation. They are directional diffusion processes.
Shear along grain boundaries is a deformation process
which leads to a relaxation of stresses in the grains
and to a strengthening of the grain boundaries. The
grain bodies are not deformed when the grain boundaries
are displaced (Ref 10). This displacement process only
leads to a decrease in the stresses which bring it aboat
and to a restoration of the correct structure of the
metal crystal.
2. Alloying of nickel with aluminium and copper greatly
strengthens the grain boundaries and lowers their
mobility. This is due to the fact that diffusion
processes in the boundary are rendered more difficult
because of the rectification of the lattice due to
internal adsorption.
3. Strengthening of the boundaries on alloying is
greater than that of the grain bodies. Therefore, in
order to strengthen an alloy for service under creep
conditions, it is sufficient to add a very e,,mall quantity
Card 4/5 of addition element. However, the grain bodies are only

3lightly strengthened due to such alloying and the grains
are easily deformed by splitting up into blocks by
polygonisation under load. In order to strengthen the
grain bodies the alloy element should be introduced in a
considerably greater quantity. It is not recommended
that the alloy element should be introduced in such
quantities as to greatly decrease the mobility of the
grain boundaries, as this tends to make the metal liable
to brittle fracture in high temperature deformation.

ABSTRACT: It.iS sufficient for the determination of the grain
orientation to know the indices of the crystallographic
elements in the pickling patterns and to have the electron
microscopic photograph of the pickling patterns (i.e. an
orthogonalprojection of the pattern). The photograph permits
the measurement of the pattern edge angles, wherefrom ('Ref 1)
the plane indices may be determined. The grain orientation
of polycrystalline samples of aluminum and aluminum--
magn*81um alloys was determined by this method. The sample
surface was poli'shed else Itrol tically (electrolyte
2/3 methanol? 1/3 nitric acids and the pickling patterns were
develbped with the reagent (Ref 2). In contrast to opinions
held hitherto it was found that the pickling patterns do not
Card 1/2 exhibit cube surfaces but a fine pickling structure of

pyramid burfaces. The surfaces are not entirely even; they
exhibit a stepped configuration, the stop faces being cube
planes..It is stated on the strength of this observation that
the determination of grain orientation is thereby rendered
more difficult and may be made with a slighter error only in
the case when 2 or 3 surfaces of the pickling patterns
exhibit similar inclination angles with respect to the sample
surface. The electron microscopic photographs shown were
taken by V. I. Syutkina. There are 2 figures and 3

TEXT: The influence of the concentration of alloying
elements on the slip and migration of boundaries in the binary
solid solutions Ni-Al (0.02 - 30/10 Al), Ni-Cu (o.1-6o% Cu) and
Ni-Co (0.5-6oo,") Co) was studied. THe lo-w concentration ranges
ifere studied particularly thoroughly since small percentages
of alloy elements exert a very stronginfluence on the properties
of grain boundaries. The alloys were i-ilade by means of vacuum
melting, using metals of 99.990,,'l purity. The average grain size
of all alloys iiras 0. 1 mm. The alloys were deformed in tension

at a rate of 200 per I-lour at a temperature of 700 C. To
prevent oxidation of the specimens deformation was carried out
in an atmosphere of purified nitrogen. The surface of the
specimens was subjected to electrolytic polishing prior to

deformation. Slip along the boundaries and migration of
boundarios waj atudied by mcaiis of an intorforomoter at a
magnification of X320 and by meano of an electron microscopo
at a magnification of X6500 after the specimens had been
extended by 29'0. The height of the slip steps on the surface,
forming during deformation along the boundaries of adjacent
grains, was taken as an indication of the degree of slip. This
value was measured with an accuracy of up to 0.1 11 , from the
displacement of interference lines. The extent of displacement
of the boundaries was judged from the distance between their
positions prior to and after deformation, measured along the
generatrix of the spec3-men. This distance was measured, with
anaccuracy of up to 1 Ii, by means of an ocular scale. The
initial position of the boundaries became visible during
electrolytic.polishing. All subsequent positions became evident
owing to slip occurring along the boundaries during deformations
It was found that two regions exist in binary Ni-base CL-solid
solutionS2 in which the concentration of the alloy element
exerts a strong influence on the refractory properties of the
Card 2/1,

alloy. The first region lies in the interval of dilute
solid solution. This region is the narrower the greater the
difference in radius, values and position in the periodic table,
between the atoms of the alloying elements and those of the
basic metal. Addition of alloy elements to nickel within the
limits of these concentrations causes strengthening of the grain
boundaries, which increases its plasticity and the life under
load in hi-gh-temperature testing. The second concentration region
is situated in an area half-way between the terminal solubilities
of the alloying element in nickel. At these concentrations, the
mobility of the boundaries decreases and their shape becomes more
complex. These factors exert opposite effects on the formation
and propagation of cracks along the grain boundaries. The shape
of the boundaries is a factor of considerable importance. It
suppresses the true influence of decrease in boundary mobility
and considerably increases the plasticity and creep resistance
of the alloy. A serrated shape of grain boundaries can be brought
about during high-temperature deformation by selecting an
appropriate percentage of alloying element.

TEXT-. The influence of the concentrations of afloying element in the binary Ni-Al, Ni-Cu and Ni-Co solid
solutions was investigated by an interferometer, electron microscope and by X-ray diffraction. The relationship
between the concentrations of the alloying elements and the grain boundary movements is not linear. The
minima and maxima are explained by the non-uniform deformation throughout the grain, by the adsorption
of impurities along the grain boundaries, and by the formation of blocks of the mosaic structure. In the
foHowing discussion, P. A. Kondrat'eva stressed the interest of the results obtained, but pointed out that she
had arrived at some different conclusions and suggested that some of the results in this work be checked.

--ABSTRACT: An attempt vras made to check experimentally the magnitude of hardening
caused by the intersection of dislocations with domain boundaries. To this end, 'the
dependence of the hardening of an ordered alloy, Cu3Au, on the size of the domains was
studied by reducing the size of the domains, which was followed by means of changes in
the electrical resistance of the alloy. The hardening coefficient was determined as a
function of the size of the domains in Cu3Au and compared to the hardening coefficient of
-u3Pd. Mechanisms are discussed which could account for the high degree of harden-
ability of alloys deformed by paired dislocations. It was shown experimentally that in
ordered alloys, strain hardening due to an increase in the extent of antiphased boundaries

The dependences T = f(t) and T = f(r) were calculated for various
values 'of I; thereby the parameter 0 (the semiangle of the emitter
cone), assumed the following values: ; 15; 25; 35 and 450. The
current density j equalled 2-108 A/cJ. The above theoretical con-
siderations were compared with experiment. The theoretical and ex-
perimental curves were in good qualitative agreement; the quantita-
-cive discrepancies are apparently due to various factors which'are
not taken into account by theory (the damping effect of the space
charge, the use of the mean current-density instead of uhe actual
current density, etc.).-The theoretical calculations for smal '1 se-
miangles a ( -< 300), are qualitatively in agree-ment with the resultz
of W.F. Dyke a. oth., (Ref. 1: Phys. Rev., 1953, 91, 5, 1043). For

rimental curves j crit = cp(a) and j =,~F(fl with U = const., were in,

of the instability of the processes involved. In practice, it is

of a thin bar the material, of which exhibits memory properties. In each of
the cases relative to the longitudinal, transversal, and torsional vibra--
tions the author sets up an integral-differential equation issuing from the
general memory theory of Boltzmann-Volterra. The solution of the equa-
tions obtained for a characterization of the vibration are preceded by a
broad investigation of the general integral-differential equation and by
the establishment of the conditions for the existence of periodic solutions
for this equation. On the basis of the theorems adduced and assuming
the coefficients of memory to be exponential the author finds for each of
