ABSTRACT: The Kafedra nemetallicheskikh materialov Moskovskogo
aviatsionnogo technologicheskogo instituta (Department
of Non-Metallic Materials of the Moscow Aviation Tech-
nological Institute) has developed so-called ion mem-
branes for salt elimination. These small-size devices
possess unusual properties. They filter the water
through membrane-electrodes and hold back the ions of
chemical elements of salt contained in water. Thus,
the water becomes suitable for producing steam. The
devices permit a ship to make a long voyage without
stopping at a port for collecting fresh water. The
districts of the USSR which are short of fresh water
(e.g. Karakhumy) will be supplied with it from its
salty lakes. Presently, ion membranes are being in-
Card 1/1 troduced in industry.

TITLE: The effects of oxide impurities on the semiconductive and
chemical properties of vanadium pentoxide
SOURCE: IVUZ. Chernaya metallurgiya, no. 5, 1964, 17-21
TOPIC TAGS: vanadium pentoxide, SiO sub 2, Cr sub 2 0 sub 3, Cu

ABSTRACT: There is a recent tendency of investigating the reduc-
tion - oxidation of metals from the viewpoint of semiconducti%,e pro-
perties. Thus, the authors observed the effects Of S102, Cr2'D3
and
CU20 on the character of thermal changes in the electrical con-
ductivity and chemical activity of vanadium pentoxide. SpecimLns
were prepared by mixing V 0 for 50 hrs. with a rated amount Df
additives and melting in irb crucibles. The specimens ore cru3hed
and passed through a 120 mesa sieve. A load of 1.5 t/cM w&s applied
to produce 4 X 5 X 40 mm compacts which were sintered ir. an

3tream at 600C for 7 hrs. Impurities exerted a considerable in-
fluence on the character of changes of the electrical resistivity of
specimens according to temperature. They affected the initial
temperature at which the conductivity of vanadium pentoxide began
predominating over the conductivity of impurities. The higher the
concentration of impurities, the greater the effect on the initial
temperature at which the inflection on the conductivity curve
appears. Low reducibility Si02 ~nd Cr 0 act in one direction while
Cu 0 acts in the opposite direction. Q authors contend that low
reEcibility oxides act as acceptors and high reducibility oxides
as donors. As Si02 and Cr203 concentrations are heightened, the
temperature of transition of the conductivity of impurities to that
of V20 increases. Impurities with a low-temperature ionization
were f9und to lower the temperature of initial oxide reduction and
i increase chemical activity. High-temperature ionization impurities
in the opposite direction. The authors believe that it may be-
come possible to predict the character of*the effect of impuritiles
on the properties of oxide. The orig. art. has: 4 figures and 1

carbon begins a physical transformation occurs,. which is
a,-companied by a slowing-down :in the increase of the electric
conductivity with temperature, From the point of view of the
semiconductor properties this corresponds probably to a
transition from impurity- to intrinsic -conduct ivit y of the oxides.

Elet.tric Conductivity E073/E335
In a special series of experiments with specimens consisting
of V205 and finely-ground graphite pressed and sintered for
6 hours at 250 0C it wag found that the electric resistaric
increast-d monotonously at all temperatures with increasing
hc1ding time., On the other hand the electric resistance of 0
pra-ssed graphite powder wa:D found to drop on heating to 300 C

beginning of appreciable reduction of the oxides coincides
with the transition from impurity- to intrinsic-type conductivity.
The results of dilatometric measurements on V 0 MoO_ and WO_

specimens, for heating and cooling rates of 150, 200 and
250 OC/h, respectively, are plotted in Fig,6 I V205' MOO3 (Fig.6a),
WO3 (Fig. 6ra )).(change in length, ji versus temperature, 0C).
The temperature was measured with an accuracy of + 10 0C and
the length with an accuracy of 0.5 VL. Thermal expansion occurs
up to 350, 44o and 680 0C, respectively, From these temperatures
upwards, which correspond approximately to the bends in the
temperature-electric conductivity curves, contraction of the
specimens was observed. This contraction is attributed to
polymorphous transformation or to plastic deformation caused
by the measuring equipment as a result of the sharp drop in
strength of the oxide at this temperature. It is concluded that
at the temperature of the beginning of the reduction process, a
change is obBerved in the physical properties, which is accompanied

and by a slowing-down of the drop in the electrical resistance
during heatting. The beginning of the intensive chemical
interaction corresponds with the transition fror, impurity- to
intrinsic-type conductivity.

ABSTRACT: In order to determine the fluidity of nickel-vanadium alloys; of a
content of 25, 30, and 35 ~~ of' vanadium, Lne wethod of pouring the
ailoys into mcids of the Ruff-type was chosen. By this method, the
tests can be carried nut in vacuum or in a neutral atmosphere. The
metal was melted in crucibles of beryllium-oxide with argon in a
high-temperature resistance furnace with a graphitic carbon heeter.
A special furnace structure as shown here allowed the metal to be
poured into crucibles without disturbing the tightness of the fur-
nace. The experimental method of Yelyutin and 14aurakh (Ref 6) was
cmp!~Yed to determine the specific gravity of the smelt. This f'cr-
merly used method is rather simple uut reliable.- By i-rivestigating

ABSTRAO: The authors study melhods for raising the safety factor of pipelines Vith
razqd'Inipples in turbojet engine hydraulic systems undertvariable stresses. The
pipelines and nipples in this study were made of Khl8N9T14teel and brazed by high
frequency current and oxyacetylene torches using PZh 5-8 'high-temperature solder.i
Such joints can withstand pressures of more than 500 kg/cm2 and uniform heating up to
700*C. It should be added that this type of union can function under extreme vibra-
tion. Turbojet engine pipelines are most susceptible to vibration arising from rotor
imbalance and gas stream pulsations. Strain tests of 60 pipelines show that the
overall maximum level of vibration stresses is 5-6 kg/mm2. An expression is given

L 05696-67
ACC NRs AP6022863
for calculating the safety factor of pipelines used under variable load conditions.
This is based on the fact that variable loads change according to an asymptotic law.
In finishing pipeline systems, a safety factor of at least 1.3-1.4 is desirable.
This can be achieved by decreasing variable stresses and lowering the static compon-
ent of normal stresses thus raising the fatigue limit. Tests show that the fatigue
limits are approximately the same in pipeline bending for tub,%t with internal fluid
pressure of 100 kg/=2 and atmospheric pressure. The fatiguellimit of pipelines is
a function of the absolute dimensions of pipe cross sect lon and local stress concen-
trators. It is shown that the experimental method is most accurate in deteimining
the fatigue limit of pipelines. Data are given for fatigue limits of_X~Lrious dia-
meter pipelines and experimental coefficients of stress concentration"~Tor nipples.
The minimum safety factor used for existing turbine engine pipelines is 1.75-2-5.
The main problem to be solved is that higher safety factor values should not be ac-
companied by increased weight and reduced efficiency of the system. Orig. art. has:

TEXT: The paper deplores the nonexistence of published systematic studies on
the effect of alloying elements on the corrosion cracking (CC) of structural steels
in acid, neutral, and alkaline solutions and in humid air. A brief survey of existing
literature is given. InvestigatioR: A single smelted batch of steel, prepared in an
electric induction furnace, was alloyed successively with various alloying blements
(4-6 different quantitative additions per element, per full-page table). Steel strips
were rolled and longitudinal specimens cut out. Heat treatment: Martensitic quench,
Z-hr low or medium temper. Specimens were surface-ground to l00x8xZ mrn and
were stressed variously within the elastic range in a 20% H2SO4bath with 30 g/1
NaGl, a scale-removing solution in which high-atrength steels (HSS) manifest an
elevated CC tendency. The tensile stresses were achieved by simple-beam, con-
centrated-load, bending in a special jig (photo shown) with a screw adjustment (to
within 0.05 mm) of the deflection. Measurements: (1) Mean time to crack formation

at a given stress level; -(Z) the "critical stress" (max. stress at which CC does not
take place); (3) a factor X (kg. min/mmZ), equal to the product of "excess" stress
applied (above the "critical stress") and the time (min.) to inception of CC. Carbon
(0.3-0.78%):.An increase in C content increases the tendency of a USS toward CC;

the T and duration of temper on the critical stress are graphed, also the corre-

content up to l.Z8% does not increase the CC tendency; a further increase in Si

The Si-containing specimens were. water-quenched and tempered at 200, 300, and

S6URCE: Korroziya i xashchita metallov; obornik statey. Ed. by V. P. Batrakov.
10 Moscow, Oborongiz, 1962, 112-117.
T XT: The paper has two specific objectives: (1) Determination of the relation-
s4tp between the magnitude of the critical stress (highest stress at which stress-
c9rrosion cracking does not occur - CS) and the crack-inception time (CIT) of a given
steel in a given medium; (2) identification of a corrosive medium that can serve in
accelerated stre s a -corrosion -cracking tests of high-strength steels JHSS) for other
media . While a metal coming from a given smelting and heat-treatment batch and
exposed to a given corrosive medium satisfies the relationship" (applied stress minus
CS) times the CIT equal to constant K," the dependence of CS and K on many factors,
such as the smelting process, the composition and heat treab-nent of the steel, the
surface finish of the metal, the composition of the corrosive medium, etc., makes
accelerated tests appear desirable. A comparison of media indicates that the stress-
corrosion- cracking tendenc of HSS is most pronounced in an etching solution con-
taining 20% H'ZSO., and 30 g71 NaCl. Comparison tests, listed in descending order

same R.H., 2 hrs drying, 2 hra observation of specimen; (3) industrial-district
atmosphere, i.e., in air drawn in on the roof of a six-story building in Moscow,
and in a non-saline moisture chamber, i. e., at 250C, R. H. 95-98%. Tabulations
and stres&-versus CIT and CS-versus-CIT graphs illustrate the behavior of speci-
mens of six different steel smeltings in the various corrosive media. It was found
that the value of the CS obtained in the etching solution can be used as a criterion
in assessing the stress -corrosion tendency of a given steel in the other media and
that with increasing CS in the etching solution the CIT in the other media increases.
It was found, for example, that a steel having a GS in excess of 50 kg/mmZ in the
etching solution is not subject to stress-corrosion cracking in the industrial-
district atmosphere. It is concluded that tests in an etching solution containing Z0010
HZS04 and 30 g/1 NaCl can serve for the development of an accelerated method for
the determination of stres s -corrosion cracking tendency in HSS in various media.

ABSTRACT: The effect Of inhibitors on corrosion cracking of 30XhGSNA superntrength
steel has been Investigated. Two heats of the steel, one carbon
-~-o-ntent of 0.292 and another experimental heat with 0.41%C were tested. The- a-t-e e11-7
specimens were hardened and tempered at 220C to a tensile strength of 170 kg/MM2 for
standard 3DKhGSNA and to 210 kg/mm2 for the experimental steel. The specimens were
subjected to tensile stresses of 145 kg/=2 by means of clamping In a special device
and tested in this state for resistance to corrosion cracking in hydrochloric and
sulfuric acid solutions with or without inhibitors. It was determined that urotropin
and BA-6 (a product of the reaction between urotropine and benzilemine) were the most
effective inhibitors. Both, however, were more effective In hydrochloric than in
sulfuric acid. For Instance, specimens tested without inhibitors showed cracking
after about 5 min In sulfuric acid and after 4 adn in hydrochloric acid. Urotropine

TITLE: Production of Multi-Charged Particles on Photographic
Emulsion Nuclei by 280-mev 7r+-Mesons
PERIODICAL: Zhurnal eksperimentallnoy I teoreticheskoy flziki,
1959, Vol 37, Nr 6, pp 16o4-1612 (USSR)
ABSTRACT: A study was made with the aid of photographic emulsions
(relativistic type P-R and less sensitive type P-',,)
of the fragment production in nuclear disintegrations in-
duced by 290-mev7r+-mesons. The angular charge, and
density distributions of the emitted fragments were
measured and plotted on graphs. The stars formed by
7r+-mesons were found to contain 223 fragments of' wnich
61 were located in the relativistic type emulsion. Some
60% of all fragments were due to the interaction of
Card 1/4 7r-mesons with heavy nuclei and 40%, with light nuclei.
