TEM- The rated pressing stress'.of- presses has-to be selected for the ex-
pected maximum pressure~required, i.e., finish-forging when the simplus metal of
the blank.is forced out into the flash. The high number of existing theoretical
and empirical formulae show th4t the.-prbblem is-both important-and difficult to
solve. Usually the zone of plastic deformation at the flash space is determined
experimentally and the data are used-for calculations. The authors considdr thi
practice wrong since the results are correct-for the-definite e.;gperiment conditiL
only, and xise a different approach. The article presents a mathematical analysis
In which the'spreadirig of the plastic deformaiion zone at the flash space is de-
termined theoretically for the minimum (instead OfLthe maximum) full deformation
energy. This principle itself had beentreated in three ptevious works,[Ref. 8:

1"BXT: ldh,)n operations of the squeezing group are used to form a
inetal component, the working pressure required.to effect the plastic
d-formation, the character of the metal flow and the distribution
of stresses and strains depend upon the frictional forces in the
area of ccntact between the tool and the metal being worked.
Experimental determination of these forces has'been the subject of
Many investigations in which, however-, methods and equipment both
,:complex and inaccurate have been used. In the present paper, its
authors deBeribe a simple equipment with the aid of which accurate
dotA on the contact friction forces can be obtained, irrespective
oi' whether static or dynamic loads are used to deform the metal,
The equipment (Fig.la) comprises a measuring block (2), split in
tLe centre and held together by a rod (4) incorporating wire strain

gauges, The measuring block is placed horizontally between the
upper (3) and lower (1) plates of a aub-press assembly, so that two.--
test pieces (shown in the diagram by cross-hatching), placed on
either side of the measuring block, can be simultaneously deformed.
The test pieces must be placed precisely in line and, in the case
of cylindrical specimens, a jigAshown in Fig.1b) is used for this
purpose. In both the upper and lower heads pins (6 and 7),
silding freely in their bushes, are ilLserted. One end of each pin
is in contact with the test piece, the other presses against a
measuring rod (5 and 8), also equipped with wire strain gauges@
The position of the measuring block can be changed with the aid of
an adjusting pin (9). When pressure is applied to the sub-press,
assembled as shown in Fig.la, the normal forces in the area 6f
contact between the measuring block and the two test pieces balance
each other. The sum of the two friction forces is transmitted onto
the measuring rod (4). Consequently, the rod is under the action
of a force which is twice the contact friction force, acting in a
given part of the conthct area whose magnitude depends upon the
position of the test piece in relation to the plane of contact of
two halves of the measuring block. The pressure exerted on the

test pieces is transmitted by the pins (6 and 7) onto the measuring
rods-.. Pressure and friction forces are recorded with the aid of
an oscillograph. This method can be used for measuring the
contact friction forces both during flat deformatton and during
l.'Ompression of cylindrical specimens deformed at various rates of
2train. By varying the distance S between the centres of the
test pieces and the parting plane of the measuring block, the
integrated contact friction force can be determined as a function
of S and tangential stresses at any point of tht contact area
,:an be calculated. In the case of flat,
rectangular test pieces,
the calculation consists of differentiation of the experimentally
determined relationship between the integrated friction force
and S. The treatment becomes more complex for a cylindrical test
piece, axially compressed. In this case, the relationship
between the tangential stresses and the experim6ntally determined
equivalent force F(a) acting on the segment determined by the
distance S (Fig.2) is given by Ir

contact area, T(r) is the sought function of the distribution of
the tangential stresses along the radius of the contact area and
rK is the current value of the radius determining the boundary of
a given segment along the cord. A method of solving this
equation is given and applied to experiments in which the contact
friction forces were measured during axial compression of
cylindrical lead.specimens of 36 mm diameter and 36, 12, 6 and 3 mm
high. Thirty tests were carried out for each do/ho ratio,
where do and. ho denote the diameter and height of the specimens,
respectively. The specimens were compressed to approximately
12% reduction in thickness at a strain rate of 6 mm/min. The:
surface finish of the measuring instrument was V, The results

TITLE: Forward-slip in the transition zones in rolling of

rZXT: Most periodic profiles, produced by longitudinal rolling,
--institute various combinations of flat and tapered sections.
in rolling profiles of this type, theye are momenta when two or
atore parts of the rolls with different curvatures are in the
deformation zone. In the present paper, an analysis is carried
Ott,!, of the conditions for the casf~ when no more than two different
portions of the rolls are simultaneou.sly in the deformation region.
All possible combinations of flat and tapered sections are shown in
Fig.l, where the direction of rolling is from left to ri!;iit.
When a strip of this type is rolled. roll portions with d.Lminishing
and increasing radii,can be simultan,~ously in the deformati.on zone;

rolling at a constant draft etc. The variants shown in Fig.1 are
divided into two groups: one compritiing the variants a,d 15 and
2 4 the other comprising variants 16 , e, N9 and it. Rolling of
capered strip under conditions of diminishing draft can be regarded
a particular case of the first group; similarly, rolling of
tapered strip with increasing draft is a particular case of the
second group, (Variants 2 and tt , less common than the remaining
ones, are not considered in the present analysis.) The geometry of
rolling according to variants a and' B , relevant to the subject
under consideration, are shown in Fig.2a and 26 respectively.
It is with reference to this figure that general formulae are
derived in the following paragraphs for the central angle of
contact 0 , and for the critical angle y, the latter being
determined from the equilibrium of the horizontal components of
forces in the deformation region. The change of the critical
angle y with the rotation of the rolls is then considered and
the relationship between y and various rolling parameters in
discussed. A formula for the momentary forward slip is then
derived, the term #'momentary" signifying the fact that the forward

in the case under consideration continually varies. The
~*alidity of this formula was checked by experiments carried out on
lead strip of the type shown on top of Fig-7- Test pieces of
various sizes were rolled under various rolling conditions.
Typical results for 2 sets of experimental conditions are shown in
Fig.7 (bottom), where the forward slip SIt is plotted against the
distance (given in mm on the circumference of the rolls or in
degrees of the angle 6) from the point of minimum roll radius.
Although the validity of the analytically established relationships
was qualitatively confirmed by the experiments, in many cases the
experimental values of S" differed from the calculated values.
This was attributed to the fact that the formula S" derived by
the present authors, did not take into account the zone of
sticking friction. There are 8 figures and 11 Soviet references,

TITLEt Poundations of the theory of visco-plastic
deformation of metal during rolling
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy. Chernaya
metallurgiya, no.lo, 1961, 50-58
TEXT: Experimental evidence indicates that a hot-worked metal
possesses both plastic and viscous properties and should therefore
be considered an a complex visco-plastic medium. In contrast to
the theory of,small elastoplastic deformations in which the
equations of state for a deformed metal establish the relationship
between the stress and strain components, the corresponding
equations for the theory of visco-plastic deformation describe the
relationship between stress- and strain (deformation)-rate
components. One~advantage of using the latter theory as a tool
for studying the mechanism of hot deformation is that it is -
concerned with increments of stress-and strain rates. As a result
the limiting condition of small degrees of deformation no longer
applies and the theory can be applied to studying the variation of
the stress-strain state at any moment of the deformation process.

The solution can be obtained with the use of the calculus of

GostekhteoriIzdat, 1949). Thus, the velocity of the metal at any
point of the volume of deformation region can be determined,
whence*all rolling parameters can be calculated. The power
expanded on deformation NA can be found from Eq.(21). If NjX
in known, the rolling torque Nn can be determined from Eq..(18),
and the roll force can be calculUed for a given roll radius.
The velocities at the entry and exit points of the deformation
region (v0 and vl) are calculated from the known value of vx.
Then, from the ratio of the initial-to-final cross-section area of

The lateral spread can be then calculated for a given draft, from

TEXT: The modern conception of the stressed and strained state of metal at
rolling complex shapes is described. In view of a great varlety of complex
shapes, a classification of shapes in groups is suggested. 1. By the form: a)
with two planes of symmetry (H-beams and other), b) with one plane of symmetry
(rails, T-beams and others), Owithout planes of symmetry. 2. By conditions of
lateral deformation: a) with a free expansion, b) with a restricted expansion,
c) without expansion. The analysis of the mechanics of metal deformation shows
that neither Brovo's nor Tafel's method can be accepted as a correct one. It
should be recommended to use electronic machines for performing calculations,
since the functions derived are very cumbersome.

TITLE: 01baing of internal defects in metal by upsetting
PERIODICAL: Kuznechno-shtampovochnoye proizvodstvo,fzio, 1, 1962, 6-11
TEXT: The author deals with research on the closing of internal defects
in large forgings by upsetting,since the mechanism of this process has
not been sufficiently investigated. Upsetting tests conducted on blanks
consisting of compound lead templates provided with artificial defects
had demonstrated that the closing of internal defects during the stress
state similar to linear strain occurred only along the forging height,
and the radial dimensions of defects had increased. It was impossible to
close the internal defects in the shape of through holes during the linear
strain. However, the closing of internal defects located along the height,
and in radial directions was made possible by all-round compression. Dur-
ing uneven upsetting,the internal defects closed only in the central por-
tion of the forging,i.e. in the zone of greatest deformation. The shape of

upsetting plates and the presence of an aperture in the lower upsetting
plate affect the closing of internal defects. A description of upsetting
on flat plates with and without oil and graphite lubricant, the mechanism
of the closing of internal defects, and upsetting of a 34XHV~WhNIM) V/
steel blank are included. The work of A. Tomlinson and I. Stringer (Ref. 1:
The Closing of Internal Cavities in Forgings by Upsetting, Journal of tho
Iron and Steel Institute, March 1958), and that of 1J.V. Rastegayev (Ref. 2,

TITLE- On the calculation of force in pressing aluminum alloy rods
PERIODICAL: Izvestiya vysshikh uchebnykh zavedenly, Tsvetnaya metallurgiya,
i:!f_no. 5, 1962, 145 - 155
TEXT: In order to develop methods of detdrm'ining the force in pressure
working of metals, the authors attempted the derivation of a formula to calcu-
late the force in rod pressing, using direct methods of variation calculus.
Force and pressure are calculated with the use of a rough, approximate metal flow
diagram( Fig 1) where the container is divided into 3 sections, the velocity
field is Xinematically possible, and value to a11.is ihe depth of deformation
spread. The following simplified formula for the necessary force in pressing
rods is derived:

satisfactory agreement makes it possible to recommend the relation obtained for
the determination of the pressing force for aluminum alloys. Calculations with
the use of formula (6) are simple and do not yield indefinite results as e.g.
Gubkin's formulae. Graphs are plotted to facilitate calculation (Figure 7).
There are 2 tables and 7 figures.

TEXT: The authors are of the opinion that for solving'the problems con-,
nected with the design particulars of a given component, e. g.- dimensions,,-
material, surface finish etc., high-speed computers can be used. Besides in-
creasing the productivity, they would eliminate any subjective solution of tech-
nological problems. Since the most simpie and widespread group of forgings area
axially symmetric ones, i.e.j forgings of the body-of-revolution type, this
type of forgings'would be the first whose technology could ~e developed by means
of high-speed computers. The authors give a detailed description of,a universal
program. which is being developed at present by a team of scientists of the Sec-
tion "Metal Working" of the Urallskiy politekhnicheskiy institut imeni S. M,

;ABSTRACT; In this paper the authors investigate the ratio T mean :T, and the iildex of
:the friction forces c9 w T :p (T Op ~re the specific forces of frl*:,~tion
mean mean mean mean
in a normal pressure averaged on the contact surface; T is the consistency limit in

shear) which most completely characterize the forces of external friction during
plastic deformation in the cold sagging of copper, zinc, and Armco iron. The de-
pendences of friction and pressure and the varioua metals are presented in graphs.
The experimental data show: 1) the forces of friction essentially depend on the
focus fom of the deformation at a given state of the wrking surface, 2) the ratios
between the friction forces and normal pressure depend on the temperature-velocity
