ABSTRACT: The choice of optimum thermomechanical conditions fo-
worIcing of uranium is complicated due to possibilitie--
of allotropic transitions resultirg in modifications
having different plasticity and strength. Due to Its
high resistance to deformation and small heat capacity,
uranium is often heated considerably during extrusicn
and rolling and changes from a int8 a_ phase. Deform-
ing samples from 90 to 60 mm at 420 'C by means of one
stroke of a friction press, the t-amperature of the
metal rises from 90 to 1000 C. Strong oxidation al,3o
influences the temperature change in the metal duri!-,g

for working of uranium by forces of pressure, the
authors investigated the rolling, ressing, drawing,
P
and die forging of uranium. Figure 1 shows the
influence of the temperature on the maximum permiss-4:--le
reduction per pass of 15-mm-wide cast uranium samples.
Uranium is exceptionally sensitive to nonuniform dis-
tributions of deformations during rolling. For
example, fine uranium strips (0.01~,-0.20 mm) may be
obtained without fracture;reduction per pass 80-85%.
The augmented plasticity is expla--ned as due to
negligible nonuniformities in the distribution of
deformation in the rolled strip. However, whon rol'--
ing cold thin plates with variable rolling direction,
the resulting nonuniformities in deformations cause
fracture of the metal. Figure 2 shows the results
of investigations of the variaticn with temperat,.-ire
of the mean specific pressure pcf, of the metal on
the rollers. The temperature increase in the metal

ABSTRACT: Zinc alloys are now used by railroads and other industries
as a good substitute for antifriction bronzes. Such an
alloy is TsAM 9-1.5, consisting of 8 to 10% Al, 1 to 2%
Cu, and 0.03 to 0.06% Mg, the balance being zinc. This
alloy corresponds to state standard GOST 7117-56. Previous
studies were conducted by German authors (Beier, W., Wolf, V.,
Nr 8, 1939; W(?iss, E., Metallkunde, Nr 4,
Z. Metallkunde
,
1940), and by Vinogradov, S. 11., Dnestrovskiy, N. Z.,
"Special Bronzes and Brasses;' Metallurgizdat, 1945; they
cover, however, only slow rates of deformation (10 to
120 mm/min), while hot working by prezz-sure involves a
high rate of deformation. The authorEi studied the latter

PERIODICAL: Tsvetnyye metally, 1961, Na. 1, pp. 72-75
TEXT: The problem of keeping to minimum the weight of the
discard from extrusion billet becomeE particularly important in
extruding costly metals or alloys, and the present article des-
cribes a method of achieving this end. The method proposed is
based on the application of a conical die, used in conjunction with
a spacing disc of a plastic metal (with deformation characteristics
similar to those of the extruded material), placed between the
extrusion ram and the extrusion billet. The principle of the
method- is best explained by referring to Fig. I which shows (1)
the extrusion billet; (2) plastic metal disc, and (3) extrusion
ram, before (A) and after (B) extrusion. The salient feature ot
the method consists in that the mating surfaces of the extrusion
billet and the spacing disc are not flat, but convex and concave,
respectively. If the correct shape of the curved interface (line

D-C-E, Fig. 1,A) is chosen, it becomes flat (line D,-C'-E,, Fig.
1,B) after emerging from the die, so that. the tail end of the
extruded rod is free from the "piping" dofect and does not have to
be discarded. A method of determining the correct shape of the
curved interface from the co-ordinato net pattern, superimposed on
the meridian face of an experimental billet, is described. Apply-
ing this method to alloy,40b (D16), extruded at 420 0C from a billet
40 mm in diameter, to an 18.4 nim diameter rod, the present authors
found that the correct interface constitutes, in this case, a
quadratic paraboloid. It is concluded that if this method is
employed in extruding metals at relatively low temperatures (below
5000C), the extrusion process can be carried out without producing
a discard from the extrusion billet. TI-iere are 4 figure5 and 2

TITLE: On the Shape of Elastic Zone in a Die During Pressing Through a
Single-Channel Flat Die
PERIODICALs Izvestiya vyashikh uchebnykh tavedeniy, Tsvetnaya metallurgiya,
1961, No. 2, pp. 1,31 - 133
TEM The shape of the deformation iseat in pressing.through flat dies is
determined by the elastic zone. The effect of various factors on the magnitude
of elastic zones has been dealt with in a number of publications (Ref. 1 - 4).
However, they do not explain the causes of a constantly equal shape of the sur-
face separating the elastic zone from the deforming metal volume. The shape of
this boundary represents a trajectory of the motion of peripheral layers of the
pressed metal. Investigations of this boundury provide data on: regularities in
metal flow during pressing; characteristics of the surface of slip in the de-
formation seat, and on the effect of the aforementioned boundary on force condi-
tions. The authors attempt to explain the causes determining the surface shape of
the elastic'zone. For this purpose it is suggested to use the principle of the
least work and the least time for the trajectory of motion of metal particles

On the Shape of Elastic Zone in a Die During Pressing Through a Single-C haxL-iel
Flat Die
(Fig. 1). The trajectories of particles from poin-t A to B can be determined ana-
logous to the solving of Bernoulli's problem of the braohistochrone which shows
(Ref. 6) that the given curve Is a cycloid (Fig. 3" which is concave in the motion
direction of the point and resembles by its shape the boundary of the elastic zone,
Another method of demonstrating the concave shape of the curve formed by the tra-
jeatory of a point moving at high speed and mViimum time is shown in Figure 4.
The straight line m - m, parallel to axis x, c;7osses the poss1ble trajectories in
points a, d, f. Time is gained when the shortor section is passed at a lower
speed and the longer section at a higher speed,, Sections of the course, passed by
a point at the same level and by different trajectories, are in the relation Ac <
< Ad < Af, i.e. at the beginning of motion at lower speed, the concave trajec-
tory provides for a shorter course, and for a longer course at the end of motion
at maximum speed, since 'the section of the trajecto-.7. below m - m are in relation
Be ',', Bd > Bf. Thus the shape of the elastic tone surface during pressing through
flat dies, corresponds directly to the principle of the least work. This Is Im-
portant when developing methods of determining forco conditions for pressure work-
ing of metals by the least work principle, usIng variational calculus. Data ob-

more precise the concepts of the effect of friction forces during the last stage
of pressing and of the nature of changes in the strained-stressed state of the
deformation seat atihis stage. The investigation was carried out with direct
extrusion of a round rod through a plane die. Factors were studied affecting
basically the slide speed of the pressed metal over the contact surfaces of the
pressing tool during the last stage of pressing when the press plate begins to
enter the reduction section of the deformation seat. Formulae are given to ca:_
culate the volume feeding the pressed work piece, the decrease per second of
the feeding volume and the rate of sliding and f'.ow through the cycl~ndrical
surface. It was found that the mean sliding ra-te of the pressed metal over the

sharply with a rapid decrease of the height. Thin increase In the flow rate of
the pressed metal and Its sliding rate along the press plate end surfaces and the
die, when the press plate enters the reduction section of the deformation seat,
and the less marked increase of these rates prior to this, are explained as
follows: before the press plate enters the deformation seat, the volume of the
latter does practically not decrease, and the same amount of metal is supplied
as is delivered to the pressed work piece. After the press plate enters the
deformation seat, its volume decreases inevitably. This entails an increase In
the flow rate of the metal and its sliding over thu contact surfaces of the
press plate and the die, at an unchanged volume supplied to the pressed work
piece per second. Thus the basic cause of the sharp increase of the pressing
force during 'the last stage of the process, is the increased sliding rate of ~h~
pressed metal along the contact surfacen of the press plate and the die. There
are 2 figures and 1 Soviet-bloc reference.

TEXT. Rapid expansion oZ the national economy envisaged in
the new programme of the Communist Party of the Soviet Union
will necessitate a corresponding increase in the production
capacity of the nonferrous metal-workina, industry and in the
range of the materials produced. This, in turn, will necessitate
the introduction of new techniques, aggkimeration of various
fabricating processes and their intensification attained mainly
by widerapplication of electrical heating and by increasing the
speed of deformation. Some of the problems created by these
developments and means of their solution are discussed briefly
in the present paper.

1) It is suggested first that the quantity of rolling stock
produced can be increased by incorporating the malting, casting
and rolling operations in one continuous line. This system is
at present applied on a small scale in the production of aluminium
foil and wire, and work is in progress on the development of' a
similar process for the production of copper-wire and rod. The
main difficulty in applying this process -to melting two-phase
alloys is their tendency to segregate dur:Lng casting, as a
result of which, lengthy homogenizing treatment, difficult to
incorporate in a continuous line, is neceissary. In this
connection, it would be desirable to nearch for alloying
additions and/or methods of casting whi.ch would ensure homo-
gene-ity of the billets.
2) The output of tubes could be incroased by changeover from
extruded to seam (straight or helical; welded tubes fabricatod
by a continuous process. The results of tentative investigations
have shown that this technique could tie successfully employed
on an industrial scale for fabricating copper, brass, nickel,
alumir-lum, duralumin and other nonferrous--metal tubes. However,
Card 2/5

s/i8o/6i/ooo/oo6/001/020
Scientific and technical E-193/E383
before this technique can be usefully cidopted, problema will
have to be solved of producing consistently high-quality welds
which will possess practically the samo mechanical properties
and corrosion-resistance as the material outside the welds A
reliable method of continuous testing of the quality of the
welded seam would have to be developed.
3) The efficiency of extrusion processes could be increased
by reducing the percentage of wasto material; this could be
attained by extruding without the formation of extrusion
discards , by increasing the extrusion speeds and by the appli-
cation of extrusion techniques sim:Llar to those used in
cable-sheathing.
3) It would seem desirable to explore the possibilities of
using ultrahigh pressures in extruision, wire-drawing, rolling and
forging processes. In addition to other benefits, solution
of this problem would bring about an increase in the strength
of the f 'inished product and a corresponding reduction in the
quantity of metal consumed.

The difficulties associated with the shortage of' some metals
ca-n be overcome by wider application of clad materials. In this
connection, there is a need for development of new methods of
thermal and mechanical treatment which lorould ensure the for.-
mation of a high-strength bond between the core and the cladcling
materials,
5) High priority should be given to research and development
work on powder-metallux-gy technIques, partIcularly as applied
to dispersion-hardened materials.
6) Friction between the tool and the fabricated metal is an
important aspect of all metal-working processes. A search
should be instigated for more efficient and cheaper lubricants
and more attention!hould be paid to the problem of pressure-
feopding the lubricant into the deformation region.
7) More attention should be paid to pracess-control and
intipection at every productiion stage. Work should continue
on the devel,?Rmgnt, of reliable and accurate testing methods, and the
stektiatici_ cess control should be more widely used.

8) There is an urgent need to devolop the theory of plastic
working of complex shapes or difficult materials (titanium.
tantalum, niobium, germanium, uranium, thorium, beryllium, etc.).
9) Since the number of nonferrous semi-fabricated and finished
articles of different shapes and sizes, made by plastic-working
processes, exceeds 20 000 positions, more attention should be
paid to specialization of new plants whose location should be
ch-DSen in a less haphazard manner.

TITLE: Experiments on the industria production of
zinc alloy- armco iron bimetal strip
PERIODICAL: Tsvetnyye metally, 1961, No-7, pp.65-69
TEXT: Laboratory investigations by the authors (Ref.l:
Koroll B.K., Bushe N.A. VNII zheleznodorozhnogo transporta,
Transzhellorizdat, Moscow, 1959 and Ref.2: Koroll B.K.,
Perlin I.L. Byull, TsIIN TsM, 1961, No.3) showed that, in
principle, bimetal strip of alloy 1AAMg-i.5 (TsAM9-1.5) with
armco iron could be produced by rolling: subseouent tests on
bearings of the material were successful. For wider service tests
a batch of the bimetal strip produced under industrial conditions
was needed. Its production served also as a check of the proposed
(Ref.2) rolling conditions consisting, essentially, in the
production of an aluminium-clad billet of TsAM9-1.5 alloy and its
combined rolling with armco iron. The aluminium was of AAl (ADI)
or AO grade and served as the binder. It was clad onto the alloy
by hot rolling (250 to 270'00 on a two-high mill (650 mm dia rolls)

at 1.3 m/sec rolling speed with 22 to 30% reduction per pass.
Rolling vras continued to a clad-billet thickness of 5.5 to 6 mm,
the ingot being 30 and the aluminium 1.3 to 10 inm initially, The
aluminium and TsAM9.-1.5 ingot surfaces were wire-brushed, Only
aluminium blanks thicker than 8.6 mn showed signs of creeping off,
but still to a very small extent, The work confirms results
obtained previously (Ref.2) on thinner ingots. To find the
aluminium thickness giving the best adhesion, 5,5 to 6 mm thick
alloy strips clad with various thicknesses of aluminium were
levelled and cut into 235 to 420 mm sheets- these were annealed
at 2500C and pack cold-rolled with a pickl;d 7.2 x 235 x 500 mm
billet of armco iron, A two-high nill (700 mm roll diameter) was
used with paraffin as the lubricant, The iron and aluminium
surfaces were wire-brushed. Satisfactory adhesion of tha alloy
y 8.6 and
with iron occurred only with aluminium cladding originall,
10 mm thick. Unsatisfactory adhesion was due to high residual
stresses (Ref.3: AynbInder, A.B. 12.d-vo AN Latviyskoy SSR, Riga,
1957) and irregularities of the contacting surfaces, Since
thicknesses of-base and cladding in bimetal strip are required to

very close tolerances, the authors studied factors influencing
distortion of the individual layers. Pack rolling of different
alloy/iron thicknesses and ratios was carried out with pack
thicknesses of 12.9 to 16.86 mm (approximating to industrial
practice). The two-high mill was used, 52 to 54% reduction being
effected per pass. After rolling, the thickness of individual
layers was measured by a published method (RefAs Gostev, B.I.,
Zillberg, Yu.Ya. Aluminium Alloy ACM(ASM) for Heavily Loaded
Bearings, GITI mashinostroitellnoy literatury, Moscow, 1959).
Neither pack thickness nor thickness rations had any effect on
deformation. The final and initial thickness ho and HO of the
pack and tile final and initial thicknesses hF and HF Of tile
iron were found to be relatod by the expression
ho /h F J-CHO/H r)0.81
Recommended rolling conditions for bimetallic strip of 3.6, 4,6
and 6.2 jnm thickness are shown in Table 3. Shear-strength
investigation of bimetal specimens taken after each pass showed
that generally this rises with increasing degree of deformation;
however, heat treatment after reductions of over 50% is essential

measure rolling pret-sure. Be--aume of the different mechanical
rropertios of the layers, the equation for the average working

where Pilot is the total roll force in kg; Bav is average strip

one of the layers, mm; D is roll diameter, mm, Calculations
show that with 4.6 and 6.2 mm thick strip, a decrease in average
specific pressure in the first pass is also a factor leading to poor
adhesion, R.A.Peskina and A.S,Gul,rayev participated in the work.

lem with planar deformation and planar stress. A solution is then
obtained for the case of a plate; weakenA* by a circular hole Vrith
stresses at infinity. The case of completo enclosure of the PIELS-
tic zone of the hole L1 is considered. (See Fig. 1). L 2 is the
boundary of the central part of the zone. A circle L 3 is drawn
with radius through the point a,,~q = /a/, /b,/,- /a/), Kolosov-
Muskhelishvit- functions qp(z) and z) are introduced which'are
analytic in the stresses zone, i.ft the region between L 2 and L 3' if

TITLE: Solution of the first Inasic axisymmetric problem in elasticity theory for a
region bounded by an ellipsoid and a sphere

TOPIC TAGS: axisymmetric problem, elaetticity theory, stretched surface, elestic

ABSTRACTI.- The author solves anlaxiay=etrio problem for a region bounded by an
ellipsoid and a sphere by a method which is a modification of a method given by
in a previous paper for solving the first basic problem in elasticity theory -,,'or a
region bounderl by two surfaces. He effects his solution by deriving an infillite'
Wstem of equations for the unkmown coefficients in his proposed representation.
The system can be solved by successive approximations. He treats the case w1iere
the normal component is equal to I and the tangentW component is equal to 0.
