TITLE: Dal'ormations of UraniLuii Subjected Simultaneously to
Thermal Cycles and Tensile Stresses
PERIODICAL: Atomnaya energiya, 1960, Vol 8, Nr 2, pp 112-116
(USSR)
ABSTRACT: Method of Investigation. Figure 1 represents the special
device operating under vacuum of' the order of 1o-5 mm Hg.
Temperature control was automatic and the residual de-
formation of uranium was studied by measuring the size
of the samples after (1) the cyclic thermal treatment
without outside stresses (a freely hanging specimen
of small weight); (2) creep investigation at the
maximum cycle temperature for intervals of time
equal to the cycling time in the next part; and (3)
cycling thermal treatment with tensile stresses equal
to those ftn part (2). Sample temperatures were
measured at three pointa by means of thermocouple

was between 5 and 100 C. Under investigation were
samples of granular sheet uranium (rolled in the a -
phase region), and uranium annealed in tile '/ -phase
region (randomly oriented crystals). All samples were
flat, of an overall length of 100 mm (woricing length,
40 mm; width, 8 nun). Thickness of the samples A, B,
C was 2.3, 2.2, and 3.2 mm respectively. Samples Cut
Across the Direction of Roll. Tables 1 and 2 sununarize
all the results obtained from the cross-cut samples.
Samples Cut Along the Direction of Roll. Results are
summarized in Table 3. Samples With Random Orienta-
tions of Crystallites.- (See Table 4.) One sees
in all cases that in the case of simultaneous
influence of cyclic thermal treatment and tensile
stress there is a considerable increase of the length
-variation of the samples compared to the creep caused
by simple te~nsion. This happens even in cases when
the stress effect and that due to the thernial cycling
are of ogositessip. There are 4 tables; 5 figures;

of specimens were controlled at these points by means of thermocoup-
les welded onto the specimens. The magnitude of the residual defor-
mation of the specimens was determined (1) after cyclic heat treat-
ment without application of external load,* (2) after cyclic heat
treatment with application of a tensile load during the heat treat-
ment cycle; (3) after creep tests at a temperature equal to the up-
per temperature of the cycle. The duration of the latter tests was
that of the full period of the heat treatment cycle, multiplied by
the number of cycles (the load during cyclic thermal treatment under
load and in the creep tests being identical). Texturized uranium
rolled in the a-phase region and untexturized uranium annealed in
the y-phase region and quenched from the P-phase regiong were tes-
ted. Specimens of texturized uranium were cut along the direction
of rolling and at right angles to ito It was found that as the re-
sult of applying a small tensile load to uraniump aluminumv zincq
a and P brass during cyclic heat treatment, a considerable residual
deformation developed; this exceeded the total deformation due to
creep and cyclic heat treatment without application of loadv by a
considerable extent. Cyclic -thermal treatment of transfer specimens

of texturized uranium sheet in the a-phase temperature range, and
also of P-brass, in the absence of tensile load causes a shortening
of the specimens, and on application of a small external tensile
load it leads to a considerable elongation in the direction of the
acting force. As a result of cyclic thermal treatment of uranium at
a constant loadp the residual plastic deformation on passing ihroL42
the P phase transformation point is greater than deformation as
a result of cyclic thermal treatment within the a-region. In a + P
brass the residual deformation brought about as a result of testing
for creep only, considerably exceeds the deformation under the in-
fluence of cyclic thermal treatment with a constantly applied load,
The change in dimensions of the specimens is in the direction of
the action of the externally applied load. The considerable change
in the magnitude of residual deformation and even in the sign of
def6rmation as a result of the action of small-stressesp,applied to
the specimen during cyclic thermal treatment, is due, in the au-
thors' view, to the fact that on applying a constant tensile load
to a specimen submitted to cyclic thermal treatment, the initial
stage of the first period of creep, in which the material exhibiis
a higher rate of deformation, is repeated; this is also promoted ;y

The Automation of Oxygen Turbooompressors (Avtomatizatsiya
kislorodaykh, turbokompressorov)
It is said in the introduction that work with oxygen turbocompres-
sors (especially for starting) can be carried out only by highly
qualified specialists, and that it is therefore of great import-
ance that the automation of such plants be completed in such a man-
ner that starting, operating and stoppingare simplified as Twach as
possible and fitted out with ;3afety devices. In the section: The
System of Automatic Start:b&,2f Turbocompressors various manip-aa-
tions are first described whioh must be taken into account when
adjusting a non-automwbized plant before starting; also other mani--
pulations which are necessary for adjusting the apparatus for norm-
al operation after starting are described. "VNIMMSY (AU-Uniion
Scientific; Research Institute for the Constraction of Oxygen Ma-
chines) designed a scheme for the automatic control of the appara-
tus, with the aid of which such functions as starting and stopping
are fully automatized ana can be brought about by simply pressing

On the Question of Underground Water on Mars
Astron. tsirkulyar, 1958, July 3, Nr 193, pp 21 - 22
The external manifestations of water on Mars are examined under the
assumption that its mean quantity per 1 km2 of the surface is equal, like
on Earth, to --' 2.7 km3, while the thermal flux, comipg from within the
planet is near to the geothermic one, i.e. 1.3 . 10 0 cal/cm2sec. The
water in liquid form, is apparently found on Mars under a thick layer of
eternal ice. The loss of moisture by the planet's atmosphere is compensated
by the sublimation of underground ice and by the evaporation of the water under
the ice in the places where the ice dmerg'66,,io,the surface. A vertical
distribution of temperature was found in the.water under the ice. It was
found that the latitudinal change in the thickness of the ice gave rise to
a horizontal temperature gradient in the water. The glacial cover of Mars
is a peculiar hydraulic"press. As a result of comparatively small stresses
(teotonio phenomena, fall of meteorites) cracks are formed in the ice. It

is possible that the canals and the dark regions on Mars are connected with similar
cracks and water holes in the ice. If this is so, then it is easy to explain the Seo-
metric peculiarities of the canals and the tendency of the dark regions to be situated
along the lines of the circulation flow of the trade winds.

TITLE- Is There Water on Mars?
PERIODICAL: Priroda, 1960, No. 9, pp, 73 - 77
TEXT- Professor A.I' Lebedinskiy has shown that the transparency of the
Martian atmosphere would inevitably lead to any water in it freezing out, The
absence of detectable water in the atmosphere is not proof of the absence of
water on or below the Martian surface. By analogy with the Earth, the Martian
hydrosrhere would be formed by secretion of wa:ter to the surface under presslire
and heat from the depths of the planet. Conditions on Mars wc-re more favorable
than on. Earth for the melting of matter in the dep-i~hs of the planet (and there-
fore for the liberation of crystalline water) and for gravitational differerit,,~a-
tion. The layers of the Martian crust weigh less than on Earth due to lower
gravity and would therefore be less of a barrier to, the movement of weter t-0 the
surface. The secretion of water to the surface is probably. at a later stage on
Mars than on Earth. According to O.Yu. Shmidt05 Posmogoaic theory, since Mars
was nearer to the protoplanetary cloud than Earth, the relative content of light

compounds (including water) in its composition must be greater., T-he quanilty of
water an Mars must originally have been comparable with, or even greater than,
that on Earth. Assuming the heat stream inside Mars (areothermic stream) to t,~-
equal to that on Earth (geothermic), and knowing the maximum and minimum tempera-
tures at the surface, the maximum depth of solid surface water layer mrast be
about 500 m at the tropics and 2 km at the poles. Below this layer the water IB
in a liquid state. Mars may therefore be covered with "oceans" of glacial conglo-
merate, i.e., ice mixed with
.- eolian deposits of mat-ter from the mountain peaks
which remain above the water. level, By analogy with Earth and the difference be-
tween peaks and ocean depths, the oceans may be as deep as 15 - 20 km, This ay-po-
thesis would explain the suprisingly even relief on Mars. Night. precipi~latlon is
observed as a I'morning aroll on Mars. There must be some sour:2e whereby t-he atmo-
sphere is kept replenished with water, otherwise R. would long ago have been de-
hydrated and there could be no atmospheric precipit'altion. The source of reDle-
nishment may be volcanic processes or else tectonic cr meteorite fissures In the

1y along the line of a "canal" and sometimes between two adjoining canals. The
cracks would become covered over with ice, bat ice ten times thinner than the
surrounding ice mass and with temperatures ten times higher than at the same level
in the mass. Such cracks might persist as flaws in the cryosphere for millions
of years. Trom his calculations of the temperature distribution in the Martian lek"
hydrosphere, the author deduces the presence of equatorial-polar circulation of
water, deviating from the meridional like the trade winds on Earth. The effect
of these currents on the strength of the ice mass would lead to cracks, primarily
aligned south-west in the southern hemisphere. Such an alignment has been obserrv-
ed by MacLaug~lin. The cracks would favor vegetation, especially in the southern
latitudes where the sun is hotter. This may be the explanation of the Martian
"canals". Since the cracks open up only episodically, the polar caps must play
a decisive role in the regular supply of water to the Martian atmosphere. Optical
measurements indicate that the polar caps are only millimeters or fractions of a
millimeter thick. Clearly this is not in keeping with the theory of the "life-
giving thawing" of the caps. The author's explanation for this phenomenon is as
follows; In the lower and moderate latitudes the night precipitation in the form
of ice conglomerate melts during the day and the water is evaporated. In the

observable phenomenological forms
PERIODICAL: Voprosy kosmogonii, v.. 7, 1960, 142-166
TEET: The author has delivered lectures both at a oonfer~ence convened by
the kafedra astrofiziki MGU (Division of Astrophysics, Moscow State Univer-
11 ity) on May 20, 1957,-and at the conference of the kafedra okeanologii MGU
(Division of Oceanography, Moscow State University) in 1958- Here, he dis-
cusses the possibility of inferring other conditions from' the hydrogen con-
.tent of the Martian atmosphere.. A. I. Lebedinskiy does not exclude the pos-
sibility of there being rock-covered frozen some on-Mars. The first section
of the present paper is devoted to problems of the existence of ground water
.-and the conservation of humidity of the Martian atmosphere. V. G. Fesenkov
offers four possible sources that may account for the generation of thermal
onergy on planetary bodies. The author believes that the thick icecap which
is covered by dust (as a result of rook decay and decay products in the

lower layers of the atmosphere), has water underneath if the water reser-
voirs on Earth and Mars are comparable. The thickness of the icecap is
thought to be 0-5 at the equator and 2 km at the poles. 0. Yu. Shmidt is
mentioned in this conneotion. Research conducted by oceanographists has
made a valuable oontributi6n to astronomy, The icecap is defined as an icy
conglomerate, and the durability of cracks in the icy conglomerate of Mars
.is discussed along with the temperature near the cracks. The inevitable
underground accumulation of atmospheric water could be compensated by cracks
in the icecap. N. P. Barabashov has published a study on the "canals" Oi
Mars. Studies by N. N. Zubov 'are also mentioned. Section 5 offers an
explanation of the nature and geometry of the "canals" and of the dark
zones on Mars. B. Yu. Levin, Doctor of Physical and Mathematical Sciences,
and V. S. Safronov, Candidate of Physical and Mathematical Sciences of the
Institut fiziki Zemli AN SSSR (Institute of Physics of the Earth AS USSR)
are thanked for their interest in the work. There are 3'figures, I table,
and 12 references: 11 Soviet-bloc and 1 non-Soviet-bloc.
