Investigation of The Effect of Some Factors on the Criticai Degree
of Deformation of Aluminium
The cast ingots 18.5 Mr, thick were hot-rolled to 3 mm, and
then cold-rolled to 1.5 mm thickness. The standard
tensile test pieces Brepared from the cold-rolled strip
and annealed at 450 C for 30 min were strained in tension
at room temperature at the rate of strain equal approx.
15 mm/min, the degree of deformation varying between 1
and 21%. The test p6'eces were then annealed in a salt
bath (30 min at 500 C) after which the average grain
size was determined. The relationship between the grain
size (mm) of pure (99.6?%) aluminium. and Al-Mn alloys and
the degree of pirliminary deformation W is illustrated
in Figure 1. The effect of the concentration of Mn, Fe,
Si, Cu, Mg and Zn in the investigated Al alloys on the
degree of critical deformation is shown in Figure 2. It
was found that while Mn &nd, to a lesser extent, Fe
caused a sharp increaEp_in the critical degree of deformation,
this property was hardly affected by the presence of the
other studied elements. The results of determination of

600 0C showed that 11n and Fe (up to 0.6%) a-re most
effective in delaying the onset of recrystallisation
and in inhibiting the grain growth during anneaiing of
deformed Al alloys. The effect of the temperatu.-e of the
deformation on the critical degree of deformation was
studied on standard tensile test pieces prepared from pure
(99.78%) cold-rolled aluminium. The test pieces were
defogmed in tension at temp8ratures varying from 20 to
400 C and nnneaied at 450 C for 30 min. after which their
grain size was determined. The results reproduced in Figure
3 in the form of a graph show that the critical degree of
deformation W increases with increasing temperature of
the deformation. In the last stage of the investigation,
the Al test pieces used for determination of the effect
of the deformation temperature on the critical degree of
deformation were subjected to room temperature tensile
tests in order to measure their elongation. Figure 4 shows
the relationship between the elongation (%) of these test
pieces and the degree of preliminary deformation (%) at

ABSTRACT: It has been shown (Ref 1) that specimeip of metals,
characterized by cubic j;rystal lattice"and, consequently,
being isotropic in respect of the th-eiiaai expansion, may
nevertheless undergo an irreversible change of their
dimensions when subjected to cyclic thermal treatmenti
the magnitude of these changes, which are an accumulative
effect of plastic deformationl4aue to thermal stresses,
should dep on the raMo--Yetween the magnitude of these
stresses and the yield point of the alloy; since the
mechanical properties and those physical characteristics
upon which depends the magnitude of thermal stresses,
change with the composition of the alloy, it follows that,
Card all other factors being equal, the thermally induced
1/4 dimensional changes of alloys of a given system should be
a function of the composition of these alloys, and the /

relationship in the alloys of the Cu-Ni system. The
experimental specimens, in the form of flat strips
measuring 100 x 20 x 3 mm, were out from cold-rolled
ghost. One heat treatment cycle consisted in holding the
specimen at the test temperature for 7 min and water
uenching. The length of the specimens was measured

with accuracy of 0.1 mm) after 25, 50, and 75 cycles.
The results of the first series of experiments, in which
all specimens were quenched from 750 OC, are reproduced

(6 et %) is plotted against the ni1mber, n, of the heat-
treating cycles for the Nil 25% Cu-Ni, 50% Cu-Ni,

(USSR)
ABSTRACT: The diagrams of the dependence of the dendrite-liquati~n.
on the cooling rate were termed "kinetic curves" of dentlr' 'e
liquation (Ref 3' by the authors of this paper. An X-ray
of rating the liquation degree is known (Refs 4,5). In the
present case, an X-ray method of recording the kinetic
of dendrite liquation was develoFel, and compared with th,~ Te--
od of microhardness (Ref 3). The method described is base!
the fact that different concentrations of the dissolved
correspond to certain values of the periods in the crys*.Fi:
tice of the dissolving metal, and thus also to a widenJni- rf
the X-ray interference lines. The dendrite-liquation de,~rw.,

TOM Vibration of the melt near the crystallization fron refiries macro-

of a continuous-cast Ingot can be recommended to refine the microstrurture.
Grain refining In low-frequency vibration Is determined by the facllftat~__'
nucleation of crystals in the liquid volume and by the tearing-off of crystal-
lites from the mold wall and their transport into the solution volume. With a
higher vibration frequency during the crystallization period, the susceptibility
of the alloy to hot brittleness decreases. Low-frequeno vibration of chill
castings noticeably increasen the ultimate atrength and k (elongation) of alloy

7,=: Results are presented of investigating the effect of the chemical
composition on hot brittleness of V95 type alloys. Hot brittleness of the al-
loys was estimated on a ring-shaped technological specimen. The ratic of the
basic crack length to the perimeter of the radial ring section (in %) was used
as an index of hot-brittleness. The casting temperature was 6900C. By varying
the Mn, Si, Fe and Mg content in V95 tYPC alloys, their susceptibility to hot
cracks during ingot casting can be considerably reduced. The effect of these
admixtures upon hot brittleness of alloys of the same type is connected with
changes in the ductility of alloys in the solid-liquid state and with changes
in the extent of the hot-brittleness zone in contirruous-cast ingots.

Therefore, in a wide range of cooling velocities (from tens to
hundreds of degrees per min) changes of technological and mechanical
properties of an a!---minium alloy of a given compoRition should not
be related to changes in the proportion of' the eutectic component.
Although the amount of the eutectic component is independent on

change sharply due to the diminution of dendritic cells of primary
crystals. Critical cooling velocities, corresponding to a maximum
of intracrystalline segregation and the amount of eutectic
component may not coincide. The non-equilibrium excess of the
eutectic compound is directly related to the difference in its
concentration on the periphery and centre of the deadritic cell
(the degree of intracrystalline segregation was measured in this
work) and not to the total content of the alloying element in
primary crystals. If the latter decrease with increasing cooling
velocity, then simultaneously the amount of eutectic in the alloy
increases. At a very high cooling velocity (a few thousand
degrees per minute) the second Oinne i-4 sp difipersed that it cannot

essentially change. The gas contained in the melt is a const-'tuent which may
strongly influence the development of linear shrinkage in the crystallization
range. 'Me wider the crystallization range of an alloy, the more conalderable
can hot shortness be reduced under the effect of dissolved gases. Also by raising
the lower limit of the effective range, i.e., by raising the alloy solidus, the
linear shrinkage of crystallization can be reduced. Another method of raising
the solidus Is to change the interrelation of the main alloy constituents or to
add special additives. Thus, e.g. according to data by V.V. Tikhonova, the
addition of 0.6% zirconium to a magnesium alloy with 6% zinc will raise the soli-
dus from 3114 to 4500C. Apart from linear shrinXage in the crystallization range,
the deformability of the alloy in the solid-Ilquid state shows a substantial
effect on its resistance to the formation of crystallization cracks. T'he author
comments on this latter feature, gives a number of examples and presents graphs
with curves of the "relative elongation - temperature" ratio, melting rates of
binary and ternary alloys and t4-,mperatuiy-- recordings obtained w1th Le-Chatteller
Salad4ne pyrometer. Ple presents the results of detailed thermal and microscopic-
analyses of the B 95 (V95) Al-alloy and points out that the lower limit of tk,--
temperature range of brittleness in most cases practically coincides with a non-
equilibrium solidus; it can be higher in alloys with isolated inclusions of the

The Bridgman technique was used to Jro-, spherical aluminum single
crvstals in a device that allowed the cooling rate and the axial
temperature gradient of the growing crystal to be regulated. At high
coolinC rate and small axial temperature gradient there is a large
subcooling zone in front of the crystallization zone, i. e., dendritic
structureo may develop in front of the crystallization zone. Crystals
grozn in this way exhibit no external defects, but their density is
insufficient. If such single crystals are etched for 20 to 50 min in an
acid mixture of 00 3 (47 parts), HCI (50 parts), and HF (3 parts), large
etch patterns will occur: holes of regular 3hape, which are bounded by
faces with minimum rate of dissolution: '~100 , 110 , or 111 . The

TrEXT: The intercrystfilline deformation of Al alloys vao investigated at
tbmperatures above the solidus line. To prevent dendritic segregation the
castings were homogenized. Tensile tests were conducted according to
1. 1. Novikov et al. (Zav. lab., no. 11 (1957); Izv. vyssh. uch. zaved.,
Tsvetnaya metallurgiya, no. lo (1958)). The microstructure was investigated
on the surface of fractured specimens 5 mm diam, the test length of
which was electrolytically polished. Using McLean's method for .
investigating intercryetalline deformation in creep, its contribution to
the total elongation of fractured specimens was determined. The vertical
component of the displacement of the grains in respect of one another was
determined on a MWV-4 0111-4) microinterferometer. Result: Round

ABSTRACTt The authors feel that the shape, size, and distribution of inclusions
of the liquid phase must have an effect on development of intergranular

ABSTRACT: The effect of high-temperature annealing on the mechanical properties of
alloy VT15 was investigated. The investigation supplements the results of G. 11.
Tarasenko and S. G. Glazunov (Metallovedoniye I tomicheskaya obrabotka, 1963, No. 2.
str. 3). The tensile strength and microstructure of the specimens were studied as
a function of the degree of deformation at various temperatures (750-1000c). The I
effects of air and water quenching and the rate of cooling on the mechanical prop-
erties of the specimens were also studied. The experimental results are presented
graphically (see Fig. 1). High-temperature aging of alloy VT15 increases Its machan-
ic6l properties. It Is suggested that the increase in the mechanical properties
is directly dependent on the_2MLin size of the alloy.

Maximum resistivity. The temperature of transition to ductile behavior varies, de-
pending on the stress state. For CuSSI this temperature was 530C, 550C, and 620C
for compression, bending, and tension, respectively. The resistivity of this com-
pound begins to drop at temperatures above 500-520C. Vacuum degassing of the CuSsi
melt lowers and water vapor blowing increases the NDT temperature as well as the
temperature of the beginning of the drop of resistivity and thermal emf. Similar
observations were made in other compounds. Thus, the transition to ductile behavior
takes place within a relatively narrow temperature range and is due to metallization
of intermetallic bonds and the increase of free electron concentration. Orig. art.
