Title Corrosion of Wire Drawn After Zinc-Plating.
Orig Pub Hutnicke listy, 1956, 11, No 2) 99-102
Abstract The technology of drawing of zinc-plated wire (W) ir.
considered, as well as the corrosion resistance (CR) of
the wire. To enhance the CR usu- should be rzdc of carbon-
steel W and the hot Zn-coating conducted in pure Zn; in
drawing, during the last paoses, a neutral ermlsion zLould
be used. The described technology of drawing nakec it pos-
oible to decrease expenditure of Zn and electric power, to
enhance the mechanical characteristics of the W, exterd the
life of drawing machines and improve the condition of the
surface of the W.

Ing. Osvald Fejdoch dealt with rolling seamless tubes
from the point of view of shaping conditions and
faults which may occur. It was found that the main

spiral cracks on the external surface of the hpllow

TITLE: 40th Anniversary of the Mining-Metallurgical Academy-in
Cracow
PERIODICALt Hutnicke/ listy, 1960, Nr 3, p 221
ABSTRACT: On December 12 and 13, 1959 the Mining-Metallurgical
Academy in Cracow (Akademia Go'rniczo-Hutnicza)
celebrated the 40th anniversary of its existence.
The present rector is Professor Engineer F. Olszak.
During the war nineteen of the professors of this
Academy were imprisoned in concentration camps of whom
two rectors and one professor died there and four
professors died soon after thoir releape. The number
of professors and docents increased from 26 prewar to
114 at present, the number of "assistants" increased
from 58 prewar to 534 at present. The number of students
increased from 608 in 1939 to 4614 at present. The
number of graduates increased from 66 in 1938 to 771 in
1959. Due to the fact that the Academy also acts as a
research institute, there is close contact between this
Institute and industry. This Academy ha3 a number

metallurgy, metallurgy of steel and electromptallurgy,
metallurgy of non-ferrous metals, technology ~f non-
ferrous metals, heat economy in metallurgical works,
rolling of steel, forging and pressing of steel, heat
treatment of steel. This establishment has several
departments and, in addition to a metallurgical
department, there is also a department for high
temperature materials, a foundry department, art electrical
engineering, mining and metallurgical department, a
mechanical engineering, mining and metallurgical depart-
ment. There are 13 chairs on metallurgy, 7 chairs on
foundry, 9 chairs on electrical engineering, 8 chairs on
mechanical engineering and 7 chairs on high temperature
materials. The author hopes that these celebrations will
contribute to closer contact between this Academy and a
similar establishment in Ostrava, Czechoslovakia, since
so far there has hardly bee- any contact between the two.
The beginning of such a contact is to be made by holding
a joint conference in 1960-61 on methods of testing metals

TITLEi Comments on the Brittleness -of AK I (Cr 13) Steels
PERIODICAL: Hutnicke' listy, 1961, No.2, pp.129-135
TEXTt It in known that for the steels AX I (6SN 17021),
containing 11.5 to 14-5% Cr and a maximum of 0.15% C, the strength,
hardness and impact strength do not change appreciably in the case
of tempering ixp to 450*C. Above this temperature there is a sharp
drop in these properties. In this paper the test results are
summarized which were obtained on tempered, quanched specimens and
also on specimens which, after heat treatment, were annealed for
durations of up to 1000 hours. In the experiments current heats
of the following compositionswere used:

The specimens were produced from rolled, annealed rods 32 x 32 mm
cross-section. For the steal A the highest hardness was obtained
for hardening temperatures of 950 to 1000*C with soaking times of
two hours. For the steel 8 the maximum hardness after hardening
was lower and the structure contained 6-ferrIte in addition to
martensite. The specimens from these steels were quenched from
the temperatures 900, 1000 and 11000C and this was followed by
tempering for 2 hours/air to a temperature up to 7500C. Fig.4
shows the dependence of the,meelanical properties on the temperature
for specimens of the steel A.quenched from 10006C and tampered for
two hours. Fig.5 shows similar results for specimens of the same
steel quenched from 900*C and tempered for two hours. Fig.9 shows
the results of long run tests of up to 1000 hours duration obtained
for specimens of the steel A at the temperatures 200, 450, 550,
650 and 7500C., quenched from 1000OC/2h/oil hardness,
impact istrength). The results of tests on the reversibility
of the embrittlement in the temperature rango 400 to 650"C are
also given. Fig.10 shows the effect of tho following heat treat-
ment on specimens of the steel At IOOOQC/2h/oil.- 750OC/2h/oil

notch impact strength on the impact test temperature for the
steel A: curve 1 - 1000OC/oil - 750OC/2 h/air; curve 2 -

R, mkg/cm2. To determine the changes in the mechanical properties
of heat treated specimens at operating temperatures, in addition to
steel A, a carbon steel C of the following composition was used in
the tests: 0.13% C, 0.27% Mn, o.18% si, 0.021% P, 0.013% S,
13.20% Cr, 0.19% Ni,'0.024% N. In addition to martensite, the
structure of the quenched specimens contained individual islands of
6-ferrite. The steels were heat treated as follows:
a) 1000OC/2 hours/oil - 6500C/2 hours/air
b) 950OC/2 hours/oil - 650OC/2 hours/air
c) 10000C/2 hours/oil - 650OC/20 hours/air
(1) 1000OC/2 hours/oil - 7500C/2 hours/air
Specimens with the heat treatment (a) were subsequently annealed at
350, 450 and 5500C for durations up to 1000 hours. The specimens
with the heat treatments (b) to (d) were subsequently annealed at

as the chromium contents in the carbide phase are given in plots,

shifted processes. The first is precipitation and correlation of
carbides resulting from martensite decomposition, which influences
not only the dynamic but also the static mechanical properties
(hardness, strength). Its kinetics cannot differ appreciably from
heat to heat, it is an irreversible process since its effects do
not manifest themselves in the heat treated states: its effects In
the case of tempered, quenched steels are very intensive and may
frequently overshadow the effects of the second process. This
second process leads to embrittlement of tempered specimens, which
is characterized by the fact that its influence manifests itself
only on the impact strength; this is a reversible process. Since
embrittlement of heat treated specimens in the case of long run
annealing at 4500C has the same characteristic, the authors believe
that embrittlement is of the same nature in both cases. Of
practical importance is determination of the kinetics of embrittle-
ment of heat treated specimens at 450%; with the exception of a
single case, the impac strength in the brittle state never
dropped below 4 mkg/cm the value demanded by steam turbine
designers. ;Determination of the impact strength at normal
temperature ~gives the results under the most unfavourable conditions,

since during normal operation the material will always be at a
higher temperature at which the impact strength in higher.
Therefore, there in no reason to consider embrittlement of worhed
AK I steel as particularly dangerous. Since the impact strength
in the brittle state is at itu lowest value after long run
annealing, it is advisable to temper the material so as to obtain
the lowest hardness, i.e. to obtain a structure of very coarse
sorblte. There are 17 figures, 2 tables and 11 references,
