ABSTRACT: A study is made of the effect of size (e) of the crystal
graIns and non-uniformity (n = Ad/d) of the interplanar
distance in the crystal lattice during permanent deformatiorL
on yield point (a.) and Brinell hardness (HB) of
metals. The exDerimental data used in the study have been
taken from an earlier iavestigation by the present authors
and from investigations by other authors, in pa--ticular
Ball (Ref 1) and Hall (Ref 5). The data are for a low-
carbon steel and pure aluminium.
The various data for as and "B are plotted against
'n 1/2 and e-1/2 and the plots are found to be straight
lines. The authors' straight line for as versus
-1/2
Cardl/3 a passes through the origin of the co-ordinate system,
indicating that a s approaches zero as the grain size

increases. Hall's straightline is criticised for note
passing through the origin and it is suggested that this
line could be made to do so and still pass through the
experimental points. 1/2
The fact that the plot of a VS. I is also a

straight line passing through the origin is used to conclude.
that eTI = const. Doubts are expressed regarding the
validity of the general view that the development of non-
uniformity~of lattice parameters during plastic deformation
of metal is caused by the development of micro-stresses.
It is further argued that Hall's view that the mosaic
structure of grains is not affected by their size-is
incorrect. . -1/2 1 1/2

of the influence of the rate of deformation has been
carried out by Braudenberger (Ref 4). Daviden-kov ',Ref 5)

slow deformation is due to relaxations of micro-stresses
within the grains accompanying slow deformation and is
broughtabout by mutual displacement of grains or grain
fragments. Such displacement has been observed in plastic-
Card2/3 deformation as well as in creep (Ref 8). In order to
elucidate this phenomenon more fully, a microscopic

in which the specimens were scratched in a direction
perpendicular to that of deformation. Micro-photographs
of slowly deformed specimens showed scratch fractures in
the grain boundaries and slip lines in grain bodies more
clearly than those of rapidly deformed ones, thus confirming
earlier reports of displacement of grains and grain L
fractures. There are 4 figures and 9 references, 7 of

ABSTRACT: Increasing attention has been given recently to the
Substructure of crystal- grains. Roviiiskiy and Rybakova
(Ref 5) and others (Ref 4).have shown that the yield-
point strength and hardness increase with decreasing'
sub-grain size. The p-resent work deals with substructural
changes in 99.99% pure aluminium and'electrolytic, nickel
during repeated cyclic loading at '45 cycles/second on a
type MUP-150 machine. Fig 1 shows the form of the test
pieces. kluminium. test pieces were annealed for two
hours at 450 - 500 or 600 OC to obtain weakly- or
strongly-developed substructures, respect-lively. Nickel
test pieces were vacuum annealed for two hours at 9000C.
The strain during tests was determined with a type

X-ray back-reflection method using a type BSV-I tube
with a copper anode and linear focus (Fig 2). Figs 3

(up to 10). Figs 3 and 7 related to aluminium
previously annealed at L~50 OC,tested under repeated and
variable sign bending, respectively, and stresses of
1.55 and 1.75 kg/mm2, respectively, Figs-4.and 6 related
to the repeated bending at stresses of 1.15 and 1.75
kg/mm2, respectively, of aluminium previously annealed
at 6oo oc2 and Fig 5 to that of aluminium. at a stress of
1.75 kg/mm2, previously annealed at 500 OC. The
mechanical properties of aluminium with weakly- and
strongly-developed substructures were compared: the
results showed the superiority of the latter material.
The work showed that in cyclic deformation the grain

ABSTRACT; X-ray studies of structural changes occurring in 99.99%
aluminiuml:6nd electrolytic nickel'Alere carried out.
Samples were annealed preliminarily deformed to 1. 2 or
4510 and subjected to cyclic stressing by bending. X-ray
pictures are shown for the annealed sample, the sample
after deforming and the sample after various numbers of
cycles in Fig 2, 3, 4 and 5 for alumin3-uni and Fig 7 for
nickel. The annealed sampleg of both aluminium and nickel
give sharp interference spots corresponding to simple
structures with fairly perfect crystallites, After the
preliminary deformation the spots are more diffuse because
there are subgraIns p-resent and the subgrains themselves
are not perfect. The behaviour of nickel under
subsequent cyclic loading; is different from that of

reappears. This restoration is greater, the greater the
amplitude of the stresses and the smaller the
preliminary deformation. No restoration is observed in
the X-ray picture of nickel. It is thought that the
difference in behaviour occurs because aluminium has a
low temper-atux-e of x-eevystallization. The increase in
perfection of the subgrains is thought to be a thermal
process causing recrystallization "in situ1F to take place.

ABSTRACT~, The authors used samples of pure electrolytic nickel and
nickel alloyed with aluminium, chromium, cobalt and iron.
The composition of these alloys is given in Table 1. The
alloys were prepared in an induction furnace filled with an
inert gas. Thq melts were subjected to homogenising
annealing and were hot-forged. After forging they were-
again annealed at 9000C and then cold-forged in three
mutually perpendicular directions in order to decrease the
dimensions of crystal grains., After cutting into plane-
parallel plates, the samples were avin annealed at temperatures
gradually increasing to 5500C (50 0 hi8her than the
temperatures later employed in X-ray studies). The crystal

ABSTRACT In the first part of the present paper the authors discuss
the methods of prepari-ng X-ray silhouettes. Four graphs
serve as a basis (Pig 1). The first of the methods dealt,.,-
with here is the "contact method", in which the X-ray film
is in contact with the sample under investigation. The re-
solving power attains here a maximum of 1L The second method
is the one introduced by Cosslett and Ni=, in which , as is,
known, an electron beam is focused by means of electromagnetic
lenses onto the anode, and from which the X-rays then depart.
The resolving power attains here 0.1 to 0.2p,.The third
method is the one described by the authors, which consists
essentially of.a tapered anode as point source of the X-rays..
A resolving power up to 0 ,6& is attained therewith. The
last method described goes under the name of camera obscura.

By this method the authors attained a resolving power below

aSh AS USSR on the development of X-ray shadow microscopes.

It is pjinted out that this type cannot cope with the re-
solving power offered by electron microscopes. A new model
is described in the second part of this paper, complying with
the third principle described above. A graphic section is
shown and details are discussed. The maximum magnification
made possible by this instrument, is 650fold; the negatives,
however, may be magnified photographically up to 2000fold.
The resolving power attains from 0.2 to 0.5,%v . For an
exemplification, two pictures of a net are shown, the first
of which exhibits a 400fold magnification, and the second,
by photographic methods, a 2000 fold magnification. The final.
part of the paper is devoted to the range of applicability
of these microscopes; in this connection two pictures are
shown depicting mineral samples, one of an insect preparation,
two of histological preparations, and two pictures of metallic

ABSTRACT:
The author points out that N.N. Davidenkov's (Ref 1) division
of residual stresses into three classes is inaccurate and
~incomplete (Ref 2), and that the third class having no physical
sense is to be excluded from any classification of stresses. It
is pointed out that the stresses in state of equilibrium in the
macrovolume cannotobe specified except for by the general
classification of stresses (Ref 3), and the terminology of the

should be better termed I'microstresses" or crystallite stresses".
The "stresses" in state of equilibrium in submicrovolumes should
be termed "lattice deformations". Terms like "deformations of
3rd class" and "deformations of 2nd class" should be avoided
since they are not scientifically founded. In an X-ray
visualization of stresses, the appearance of a line shifting
should really not be applied to the classification of stresses.
on considering that an extension of X-ray lines also depends on
the size of blocks and other factors, the inexpediency of a stress
classification on the basis of X-ray phenomena becomes even more
evident. As the weakening of the line intensity in (Ref 1) is
referred.to "stresses of 3rd class", it is not dealt with
(for the above-mentioned rep-sons). There are 4,Soviet references.

TEXT: The results are described of experimental investigation
of the residual deformation ofthelattice, and consequently*of the
oriented micro-stresses, on the magnitude of residual irreversible
deformation of specimens made of steel 45 in pure compression and
tension. After machining, the specimens were annealed in a
vacuum furnace at 7860C and then deformed by means of the test
machine VIM-1-1A (IM-12A). One series of specimens was subjected
to pure compression, the other to pure tension. The rate of
deformation was 2 mm/min. The residual deformation of the lattice
was measured by X-ray diffraction and is shown graphically as a
function of the residual irreversible deformation of the specimens.
The residual deformation of the lattice is taken as a measure of the

oriented micro-stresses?, it shows a maximum value at about 1%
residual (plastic) deformation of the specimens. On further
increase of the plastic deformation of the specimens, the residual
deformation of the lattice falls continuously. The oriented
micro-stresses are therefore at a maximum at plastic deformations
of about 1%. Therefore. plastic deformations approaching 1%
should be avoided if oriented micro-stresses have an adverse
~effect. There are 1 figure and 6 references: 3 Soviet and 3 non-

Again, high scattering power is secured by the use of materials with
large R. However, a comparison between the results of the usual small-
angle scattering and those by Lambert and Guinier is not 3c easy. In this
connection, the p'a'per under review reports on studies made on nonannealed,
low-absorbing BeO, which exhibits a considerable inner submicroporcsity
(fluctuation of pore size from 20 to 250 A). With a view to simplifying
the determination of L, the authors developed a method allowing the direct
determination of Lfrom the measurement of the scattering intensities

mediate vicinity to the counter) (Figs. 1 and 2). The setup described was

TEXT: The authors report on the results of investigating the relaxation of
orlented residual micro-stresses in Ni-base alloys with Cr, Fe, Co and Al addi-
tions at temperatures in the range of from 20 to 4oOoC. The authors measured by
the x-ray diffraction method the residual deformation of tlie'lattice, originating
as a result of tensions exceeding the elasticity limit (5 - 10%) and subsequent un-
loading of the specimens, and also changes in the residual deformations taking
placein the course of time. It is proved that the optimum increase in the re-
laxation resistance of alloys is obtained with Fe, while Cr yields the poorest re-
sults. The relaxation resistance decreases with a temperature increase; this
takes place abruptly in pure Ni and in the least degree in Ni-alloys with 12.4

agreement for aluminiurri. For copper agreement is not so good
and this is attributed to differences in measuring conditions
(additional influence of heating and cooling cycles). There are

TEXT; The spontaneous increase in intensity of Debye lines,
indicating relaxation of distortions in the lattice, was
investigated. Homogeneous fine grained, cubical samples were
prepared from 99.99% aluminium and electrolytic (99.92%) copper.
X-ray photographs showed that the samples possessed no texture.
An X-ray photoxraph was taken of each specimen. The specimens
were then slowly compressed in three mutually perpendicular
directions in several operations, giving a total reduction of
about 5OV.. The hardness.of aluminium and copper increased by a
factor of two, which showed the presence of considerable lattice
distortions. Further X-ray photographs were then taken over a
period of 500 hours. The integral intensities of the (420)
aluminium and (400) copper lines were measured. After deformation,

the intensity of the aluminium line decreased by 45% and that of
the copper line by 41-45%. After a further 500 hours the
intensities of the lines were restored near to their original
values, At the same time the intensity of the background
de'ereased. These results were interpreted as meaning that
lattice defects developed during cold working are healed after a
time and that the distortion is therefore relaxed. The data were
analvsed and it was shown that the curves of relaxation of
d-istort�on could be explained by two -independently occurrIng
processes. The first of these processes takes place at a constant
rate, and is completed in 940 and 1480 hours for aluminium and
copper respectively. The second process takes place intensively
a'. first and then the rate sharply decreases. This process is
almost complete after 100 and 200 hours for aluminium and copper
respectively. Hardness measurements confirmed that relaxation
takes place with time. The results of studies of relaxation by
hardness measurements will be the subject of a separate report.

TEXT: Most authors mention only an increase in the fatigue
strength as a result of increasing wor k hardening produced by
applying tension. N. 1. Chernyak (Ref,l., "Fatigue strength of
preliminarily stretched steel". Symposium Tr. In-ta stroitel'noy
mekhaniki AN.UkrSSR,,1953) found that a small amount.of plastic
deformation by tension does not increase but lowers the fatigue
of steel. For,J = 1.0-2.6% a minimum fatigue strength is reached,
then the -fatigue strength increases and for J= 12% it reaches
a value corresponding to that of undeformed steel. The work
described in this paper was carriet! out for the purpose of

Several batches of specimens, 12 in each batch,, were produced.
The shape ofthe specimens was such that the same specimens could
be used,without further machining,for the fatigue tests. The
gauge length was 22C mm, the 20 mm long central section of which
had a diameter of 8 mm. Fig.l. After machining to the desired
size and surface quality the specimens were annealed in vacuo
at 7800C for two hours and then allowed to cool together with the
furnace., Following that, they were stretched at a rate of
2 mm/min within a range of 0 to 10%,, For the gauge length the

results of the authors of this paper (curve 1) is attributed to
the fact that Chernyak did not anneal his specimens after
machining. Fig.2 also gives the relatiog between the magnitude

The x-ray method shows that,in the process of stress relaxation,structure per-
fection of reflecting cryatallites decreases and coherent constraint in them is
disturbed. Simultaneously there occurs a turn of grains and their mutual displace-
ment. Thus, basic mechanism of stress relaxation in metal (at room temperature)
is cla8to-plastic, a shear mechanism. Stress relaxation is noticeably influenced
by magnitude of grain, degree of preliminary plastic flow, content of impurities,
test temperature, distortion of lattice,and level of constraining forces. Hardness
of HB metal, similar to relaxation stability, is determined, on the one hands
by substructure and, on the other, by constraining forces.and distortions of lat-
tice. Therefore, among these mechanical characteristics a correlation is observed,,-

ABSTRACT: /he stability of fatigue defects in metals was studied on both aluminua
and-goppef'specimens.. The study supplements the results of an earlier investigation
by B. M. Rovinskiy and.V. G. Lyutsau. (F)24, 1961t 12, 305). The work waft carried
out by measuring the change in x-ray scattering4w the metal specimens in the fa-
tigued and relaxed state. The affect of ~gingfon the plasticity and durability of
cyclically deformed copper was also studied The experimental data obtained in
this part of the investigation were treated after the method of N. W. Davidenkov
and G. T. Nazarenko (ZhTF., 1953, 23.9 741). The experimental results are presented
graphically (see Fig. 1). It was found that the intensity7 of,scattered x-rays,is
notably deplandent on deformation of the cry tal lattice (caused by the cyclical
deformations) and on aging (connected vith the relaxation of the deformed crystal
