(precipitation of Ni3Ti at the grain-boundary regions and in the
interior of the grains) and in a decrease in the lattice
parameter. The results of the next series of experiments
showed that the hardness of the steel studied decreasedon 0
heating, reaching a minimum of approximately 160 HB at 600 C,
then increasing to a maximum of about 210 at 8oo 0C and
decreasing on further heating to reach the value of - 50 at
1. 0000C~, the final decrease in hardness was attributed to
coalescence of the hardening-phase particles and softening of
the solid-solution matrix. Since the preliminary ageing treat-
ment, recommended for parts operating at 680 - 750 C, was
16 hours ageing at 750 0C, parts operating at 800 0C would have
to be aged at, say, 850 OC and the effect of both of these
treatments on the creep properties of steel E1692 was studied
in the next series of experiments.2 The results are reproduced
in Fig. 2, where the stress (kg/mm ) is plotted against time-tow-
rupture (hours) at 800 OC, Curves 1 and 2 relating to specimens

preliminarily austenized at 1 150 0C (2 hours at the tempering
temperature followed by air-cooling) and0aged for 16 hours at
750 OC (Curve 1) or for 20 hours at 850 C (Curve 2). It will
be seen that although in the high applied stress
(12 - 24 kg/mm2) range the0resistance-to-creep of specimens
preliminaril9 aged at 750 C was higher than that of material
aged at 800 C, this difference practically disappeared in the
low-stress (i.e. long time-to-rupture) range. Since no
anomalous changes in the elastic modulus or heat-conductivity 0
were observed in the steel studied when heated from 700 - 800 C,
it was concluded that this steel retained its high thermal
stability at 8oo 0C and could be recommended for use at this
temperature.

tests were done in saturated vapor at 330C under a 150-bar pressure
and 16-18 kg/mm2 stress and for some specimens in a 42% magnesium

indicator* of susceptibility to corrosion cracking. Susceptibility
to corrosion cracking depends upon the electrochemical behavior
of 'the structural components,which in 'turn is determined by the
chemical composition of the components. It can be assumed that
steels in which ferrite and austenite are both in the.passive state
and have roughly the same dissolution rates are susceptible to
corrosion cracking. Two-phase steels containing 0.05Z C, 19*OZ

ABSTRACT: The penetration of helium through the walls of metallic
tubes or cast bushings has been investigated at temperatures up to
800C and pressures up to 100 atme Seamless tubes of stainless
lKhl8N9T (AISI321) steel 24 x 1.5 to 32 x 4.5 mm in vLze were aub-.
jected to an internal pressure varying from 52 to 100 atm for 12-90'

tested at a pressure varying from 40 to 80 atm for 50-72 min at
700C, and tubes of E1437B (NLmonic 80A) alloy 7 x Oo5 and IOo5 x40 ma

for 3 min, respectively. Practically no 'helium leak was observed
through all tube walls tested at pressures below 60 atm and tem-
peratures up to about 600C, Only lKhl8N9T steel tubes (27.x 3.5 and
27 x 1.5 mm) under a pressure of 60 atm at 600C, and E1437B alloy
tubes (10.5 x 0.5 mm) under a pressure of 100 atm at 700C leaked he-
lium. No leake were observed In all tubes subjected to external he-
lium pressure. Thus, it appears that the penetration of helium
through the tube walls occurs because of submicroscopic cracks
appearing in the material subjected to sufficiently high Internal
pressure at high temperatures and not because of diffusion# The
detected leakage of helium,, less than 10-12 I/cm2eaec, was within the!
limits of measurement,errore No tensile strength changes were
observed in the Investigated materials after helium and air-pressure

TEXT: The long-run (at 650*and 7~O OC, with maximum duration
of 1 800 hours) and short-run strength, ductility and impact
strength of the base metal and of weld seams immediately after
welding and after long holding of the specimens at elevated

impact and bending tests'. The strength and ductility were
determined at 20, 35o, 6~O and 750 OC; the yield point was
determined by measuring the deformation by means of an instrument
with a scale division of 0.02 mm. Conclusions: weld seams on
the steel Khl8Nl2'Lkl2T, produced by means of automatic tube-welding
equipment with non-melting electrodes in an argon atmosphere,
have the same strengtiv as the base metal. No appreciable
embrittlement occurred after holding the specimens at 650 and
750 OC, respectively, for durations up to 2 000 hours. Investi-
gation on 900 bends of 3 x 10 x 100 mm specimens with respect to
intercrystallite corrosion, according toothe QI method with and
withou. heating of the specimens at 650 C for 2 hours, showed
that the welding seams did not tend to develop intercrystallite

ABSTRACTt High-boron steels containing more than 0.2% boron have
low ductility and poor forgeability owing to the presence of a low-
melting and brittle boride phase, which solidifiec between dendrites.
Hot pressure working and heat treatment can change the structure and'
mode of distribution of this phase, but they do not improve the duc-
tility. Iron and chromium form primarily lower borides of the Me2B
type whose specific weight does not exceed 6.5-&/cm2. Thus, in a low-
carbon steel alloyed with lZ boron, the content of the boride phase
Cord- 1/ 3
ACCESSION NR: AP4042813
is 12% by weight and 14% by volume. The notch toughness of this
steel does not exceed 2 kgm/CM2. An attempt has been made to reduce
the volume and hence the detrimental effect of the boride phase by
additional alloying of high-boron steel with niobium, which forms '
primarily higher borides of the HeB2 typee Tests were made on three
low-carbon steels? designated 1,2, and 3, with respective contents of
0.03, 0.03# and 0.06% carbon, 2.16, 1.56, and 0.942 boron, and 0.7, i
1,38, and 1.22% niobium. It was found that with an increasing nio-
bium:boron ratio,the content of the boride phase dropped from 24.2
weight% in steel 1 to 9.0 weight%. in steel 3. Simultaneously, the:
iron content in the boride phase dropped from 64*5% in steel I to 1
75.5% in steel 3; the niobium content in the boride phase rose from.',
2.1% in steel 1 to 7.OX in steel 3. It can therefore be expected
that alloying with nLobLum will have a beneficial effect on the duc-i
tility and forgeability of high-boron steels. Origo art@ has three

ABSTRACT: The authors investigate the influence of heat treatment conditions on the corro-
sion stability of zirconium alloys containing 1.0 and 2.5% of niobium. These alloys have been
developed in the Soviet Union for nuclear reactors. ~ Results cover the corrosion of zirconium
alloys in vapor at 400C and 100 atm and the appear"ce of samples held 950 hr. at high tempera-,
ture-hig)i pressure conditions. The authors investigate double annealing, annealing for 30 min
at 7001C, 50% cold rolling without and with 10 min 560C, and 30 min 700C annealing. An analysis!
of the results shows that the best corrosion resistance Is achieved by double annealing. The
effect is the strongest in zirconium alloy with 2.5% Nb. Orig. art. has: 2 figures.

TITLE: On the Problem of Utilizing Dispatcher's Traffic Control Lines Serving
Single-Track Sections (K voprosu s zagruzke linii dispetcherskoy

ABSTRACT: With the existing system of the centralized traffic control, the code
line is overcrowded with sendings, indications come late, and dispatcher's
work is hampered. The Chair of Automation and Telemechanics, Leningrad
Electrotechnical Institute of Railroad Transportation Engineers, surveyed the
centralized traffic control system at a 10-block single-track RR section. The
survey was conducted over 3. 5 days. It was found that 53 control and 324
indication sendings were transmitted per hour on the average. The maximum

number of sendings was 508 per hour; the minimum number, 248. The
coefficient of hourly irregularity of line utilization (the ratio of maxirnlm
average) was found to be 1. 35. Average transmission time for one
with a spacing between the sendings was found to be 4.5-5. 0 sec. Tht'
maximum possible number of sendings was found to be 720-800 per The
average utilization of the investigated section was 52%, the maximurn 7 H/o, A

and, according to the dispatchers, do not disturb normal operation. For that
reason, speeding up the signaling is not a dire necessity. A high-speed
centralized traffic control system will be particularly efficient if the Jhn~-~
utilized in a nonuniform manner and at the moments of train crossing W. here
the blocks are identical. The following conclusions are offered:

(1) a centralized t,raffic control system for a single-track section having a
block nonidentity factor of 0. 6-0.7 should be designed on the basis of a 5011/0
code-line utilization; (2) with a nonidentity factor over 0. 7, all the more for
the sections with identical blocks, the 50% basis of line utilization does not
exclude considerable overcrowding of the line at some moments; in such ca~~k,,S,
a high-speed centralized traffic control system should be used because it cut.:;
line overcrowding and makes an Increased number of units possible.

Abstract: The diasporic nature of Rumanian bauxites prec-
ludes the possibility of their processing by the
method of Bayer;'they can be effectively utilized
by producing Ca aluminate as the intermediate pro-

Abstract: of Seailles, by gypsum or by anhydride in order to
obtain, on clinkering, in addition to soluble Ca
aluminate, gases containing SO 2* Semi-production
scale experiments, carried out in an industrial
furnace, demonstrated the possibility of a con-
current production of H2 SO from gypsum and of
Al 03' by clinkering of a Aixture of gypsum, bau-
xi~e and coke, with the formation of soluble Ca
aluminates. The resulting gases contained 8-11% SO 29
which permits their utilization for the production
of H2SO4 , and also for sulfitization of cellulose.
