ABSTRACT: Authors made tests on molybdenum which was obtained by
powder metallurg:
method, on cast molybdenum, on cast molybdenum alloys with
admixtures of zirconium
titanium as well as cast nolybderm alloys with simultaneous
admixtures of zirco-
nium ard titanium. For selection of recrystallization conditions,
the samples
were heated to 1250, 1300, 1400, 1500 and 1600 degrees with holding
at 5. 10, 15,
20 and 30 minutes. The microstructures were studied and optdnum
annealing con-
ditions were established. In addition, treatment conditions were
established
which produced the most developed polygonized structure in the

polygoniza-
tion raises the temperature of subsequent reer7stallization which is
important for
employing molybdenum and its alloys at elevated temperatures. As a
result of
development of polygonization in the tested materials, an increase of
resistance
to small plastic deformations occurs. Orig. art. hams 6 figures.

.residual plasticity). They were tempered at 240-265C. It was
established that a
combined thermal and mochanical processing resulted in a good
combination of high
strength and the desired plasticity. The assemblies for
thermomechanical treatment,
.of steel spring bands are not complicated., can be installed in any
plant., and may
,be used in mass production operations. The strength and plasticity
values of the
,55KhGR spring bands obtained in a continuous rolling mill were much
higher than
those obtained in the laboratory. The hardening effect of the
thermomechanical
.treatment produced 2asting results, Orig. art. has: 3 tables and 2

samples. The 55KhFA
,steel composition was 0.50% C, 0.65% Mn,.0.25% Si, 1.28% Cr,
(,.17% V, 0.02% P, and
;0.02% S. The 0.8 ton ingots were tempered at 700'OC for 2 hours
and cut. The hard-'
i
,ening was carried out by means of beating to 8700C, quenching in
oil, and tempering,
.for 2 hours at 2000C. The high temperature thermal working was
conducted as fol-
mlows: austenization at 9000C in a furnace was followed by
quenching in oil, forging
into bars with 5.4 mm in diameter, tempering for 2 hours at 2000C,
and grinding to
i4 mm in diameter. Samples with 4 mm in diameter and 40 mm in

ABSTRACT: This is a continuation of previous investigations of the
Czechoslovak ChSN 16,140
machine steel (0. 44%, C, 3. 7% Ni, 0. 84% Cr) of the 40KhN4 type
(Bernshtcyn, M. L. , Dre-an,
N. Metallovedeniye i term. obrabotka. metallov, 1965, no. 6, 3;
Goller, R. Materialovy
Sbornik-, SVUMT, 1965) with the difference that it deals with
combining the high-temperature
thermomechanical treatment (HTTMT) of this steel (deformation at
920-950*C, followed by
low-temperature tempering at 100, 150 and 200*C for 2 hr) with
subsequent deformation of its
martensitic structure by cold rolling. HTTMT enhances
theplasticityof steelandhence prevents

tempering at 100*C is ineffective; it is only following tempering
at 150-200*C that the positive
effect (increase in strength without detriment to the plasticity
induced by HTTIMT) of sub-
sequent, (following HTTMT) deformation of martensite manifests
itself and the ultimate strength
of 40KhN4 type steels rises to as much as 300 kg/mm2. This
favorable change in properties
following HTT ALIT + cold deformation of martensite is due to the
processes of dispersion harden-
Iing in the partially recrystallized structure of the material.

ABSTRACT: An equation is derived for determining change in wall
thickness
per pass in drawing (D) tubes (T) without mandrel. This formula
shows that: 1) Change in wall thickness depends primarily upon
the
ratio of the initial thickness So to the initial outside T
diameter
DO' upon the reduction ratio E, and upon the coefficient of
tension
B; when the S -D ratio is very small, the thickening of the
wall is
