The Interaction between Soot and Sulphur in the Process of Rub-
ber Vulcanization (0 vzaimodeystvii sazhi 9 seroy v protsesse

PERIODICAL: Doklady AN SSSR, 1957, Vol- 116, Nr 1, pp. 105 - 108 (USSR)
ABSTRACT: First, a short report is given on previous works dealing with
the same subject. The present work contains kinetical data con-
cerning the interaction of soots (gas black, lamp black) with
sulphur and with the accelerators. In connection with the in-
vestigation of these problems the following was studiedt The
interaction between radioactive sulphur and soot at temperature
conditions which corresponds to vulcanization. The ads..xrption
of caoutchouc molecules from the benzene solution by the surface
of soot particles. The influence of pre-heating the soot sul-
phur accelerator mixture upon the physical and mechanical pro-
perties of the types of rubber on the basis of various synthe-
tic rubbers. There follows a description of the experiments.
First, the kinetics of the connection between radioactive sul-
Card 1/3 phur with a gas black and lamp black is discussed. Three experi-

mental series were developed on this occasiont I. series: The
exactly weighed quantities of soot are mixed with equal quanti-
ties of radioactive sulphur and are then heated at a temperature
of 1450 for 1, 3, 5, 8, 10 hours. II. series: Before being mixed
with the soot the exactly weighed quanPtiea of radioactive sul-
phur were kept at a temperature of 145 for I - 10 hours and
were then mixed with the soot. III seriest The exactly weighed
quantities of soot and of radioactive sulphur were mixed and not
heated. The experimental series II and III inadepoooible to ex-
plain the quantitative aide of the adeofption binding of sulphur
with soot. By comparing the remanent radioactivity of the I. ex-
'perimental series with remanent radioactivity of the second it
was possible to obtain a true picture of the chemical bondbe~-
ween sulphur and soot. On the occasion of the heating of soot
with sulphur it is certain that a chemical bond between the two
is formed. Even after a 600 hours' extraction of sulphur with
benzene it was not possible to remove all the sulphur from the
mixture with soot. Gas black is more strongly bound to sulphur
than lamp black. The authors then deal with the adsorption of
the caoutchouc molecules by soot-sulphur complexes and with the
influence exercised by the pre-heating of the soot with accele-

TITLE: Substructural changes of cold-deformed nickel and copper in the
stage of recovery through induction heating
PERIODICAL: Doklady Akademii nauk BSSR, V- 7, no. 2, 1963, 124 - 126
T EXT ; The influence of temperature and speed of heating on the change of
the relative distortion Aa/a of the crystal lattice of the second kind and of co-
herent x-ray scattering blocks was studied. Samples 20 x 10 mm in diameter, with
.diff6rent degrees of deformation (5, 10, 15, 30, 50, and 75%) were heated in the
power generator mr3 -102 (MIGZ-102) with a speed of 30 and 300 degrees per second,
and temperature was controlled with the thermoelectric pyrometer T911-1 (TEP-1)
developed at the (DT14 AF. BCCP (FTI AS BSSR). The samples-were subsequently
sawed under cooling, perpendicular to the direction of sagging, etched with con-
centrated 'D'03 to dissolve the riveted metal layer, and x-ray photographs taken
with the.ionization device YP.0-50 (URS-50). The copper standard was annealed
at 5100C and the nickel standard at 8000C for 45 minutes with subsequent cooling

down with the furnace. The fact that the relief of distortions of the crystal
lattice in copper takes place more quickly than in nickel is explained to be due
to the smaller interatomic forces in copper. The change of the distortions of
the crystal lattice depends on the speed of induction heating, both for nickel
and copper. Mien, for instance, a temperature of 2000C is reached at the rate of
30 degrees/second, the value &f t-,a/a for copper is 1.1.10-4 and at the rate of
300 del ees/second - F5-10- , while the corresponding values for nickel were
9.2-10-W and lo.6-lo- , respectively. Theintensity of growth D of the coherent-
scattering blocks when a temperature of 2000C is reached at the rate of 30 de 'T ees
per second is 4.75-10-6 em and at a rate of 300 degrees per second r 4.35-10- C'm
for cop 9er, while the corresponding D values for nickel are 4.5-10' em and
4.0-10- cm, respectively. Thus, the stage of recovery is characterized chiefly
by the decrease of the relative distG rtions of the crystal lattice, while the
intense growth of the coherent-scattering blocks should take place already in
the stage of recrystallization. There are I figure and 1 table.

ABSTRACT: According to Kirchhoff, the equation of equilibrium (Eq 1)
(Ref 1), of a thin rod straight when unstressed but becoming
bent and twisted when forces are applied to its ends, can be
identified with the Euler equation of motion of a rigid body
turning about a fixed point. This analogy can be further ex-
tended to the effect of "Jump" from one form of equilibrium
to another by identifying it with thop"ical pendulum (Eq 2)
(Eq(3): s - length of cord, Po - forco acting on the point
,0 of the rod, H = EI - bending rigidity, angle of
tangent to the direction of P0 ; Eq (2): t tPime of
oscillation of the physical pendulum, P - weight of pen-
dulum, A moment of inertia in respect of the axis of
rotation, - angle of pendulum from the vertical, a
,distance from the suspension point to the centre of gravity),
The following comparisons are made- the length of cord s

can occur when other factors (such as load) do not change. In
the case of compression and bending, these two forms of
equilibrium 9 if the axis of the rod has a different number of
characteristic points, i.e. the form of equilibrium shown in
-Fig 19 represent the position of the pendulum with no lowest
position being reached which corresponds to the rod with no
compression points. The form of equilibrium shown in Fig 2,
corresponds to the oscillation of the pendulum between the

in Fig 3 corresponds to the oscillation between the point
t - 0 and t - T on the return. The oxperimental verifi-
cation was made with the pendulum typ-- MK-30, where the re-
sults showed sufficient accuracy for the effect of "jump",
for example, in 1.25 see the pendulum reached the second se-
quence of oscillation with the angle amplitude 1800, the
first sequence - 1220; in 1.67 see the gendulum reached
the third sequence with the amplitude 10 and the second
1300. Thanks are given to K. B. Kurenshchikov and V. I.
Zaporozhskiy for their help in the experiments. There are

polynomial as suggested by I. I. Eterman (IVUZ -Mate matika, no. 3 (28), 1962). The
stability of oelf-oscillations of the above equation is investigated, and aa lddle;,t of the
degree of approximation is given. Orig. art. has: 24 formulas.

TEXT: In the present paper, the method and the results of investigation
of nonsteady temperature fields of fuel elements of water-cooled, water-
moderated nuclear reactors are given. Investigations were carried out
of the BBP(VVR) elements used in atomic power plants of the USSR, viz.
the elements in the center of the core. The system (1) of differential
equations for the temperature field of such elements is written down, and
the boundary conditions for the solution of this system are given:
Boundary conditions of the fourth kind at the points of contact of in-
dividual layers of the elements, such of the third kind on their outer
surface, and the initial condition til f(r), where i denotes the

the method of hydraulic analogs (Refs. 4,5 6 was used in this case.
The investigations were carried out on a hydraulic integrator by
V. S. Luklyanov (Ref. 4)- When investigating the temperature fields of
the elements mentionedg this method made it possible to take account of
the change in the heat-transfer coeffi'cient in the materials of these
elements with temperature, the change in the gap between the core and
the can of the element on heating, as well as, with sufficient accuracy7
the influence of the negative temperature coefficient of reactivity. The
temperature dependence of the heat-transfer coefficient of uranium
dioxide was determined from formula (3). The values calculated from this
formula agree with those of Ref. 7. In determining the influence exerted
by the negative temperature coefficient of reactivity, the continuous
variation of reactivity was replaced by a number of successive stepped
changes (Fig. 1). The experiments are briefly described. By means of the
hydraulic integratory the temperature :fields of the reactor were
examined under starting and emergency conditions, The results (Figs. 3
and 4) show that the elements of the type under consideration are very

ABSTRACT: The authors describe a uranium-water critical assembly put into opera-
tion in April 1965 at the Institute of Nuclear Power Engineering,AN BSSR. The ins-
tallation is designed for experiments on "clean" reactor cores. The stand for the
critical assembly consists of the following basic elements: an open tank, compo-
nents for the reactor core, a system for filling the moderator and controlling its
level, a tank for storage and emergency dumping of water and a system for shielding
and control. The open tank is a cylinder 1600 mm high and 1500 mm in diameter.

~Frovision is made for varying the thickness of the lower reflector and for facili-
tating assembly of new reactor cores. Two safety rods are used, each consisting of
two sections: an upper section containing a fissionable material (a type EK-10 fuel
element), and a lower section containing a moderator material (boron carbide). The
chain reaction in the assembly Are controlled by varying the level of the moderator.
:The device is used for experiments on determining the critical masses of "clean"
reactor cores in a wide range of nuclear concentrations of hydrogen and U235, on
,the distribution of flux density for thermal and epithermal neutrons, etc. Orig.

TITLEs Teaperature dependence of Armco iron yield point
PERIODICAL: Fiiika tverdogo tela, V. 39 no. lot 19619 3207 -3210
TEXTt Thet:ging process of cylindrical Armoo iron samples (0-03 - 0-04%
carbon con nt) was examined. The samples were vaouum-annealed for two
hours at 600% and then left in the furnace to cool down. All annealed
aamples were pre-deformed at 200C by 4% until a stress afo' oorresponding
to the limit of the plastic rangev was attained. Fracture followed in
each case. One group of samples was quickly cooled down to -76 and
-1960C, &nd deformed at these temperatures with stress dfT forming as a
result. The other group of samples was aged at 1000C for 15, 40, and 60
minutes. Thereupon, all samples were deformed at 20, -76, and -1960Cp
and stress a appeared. The plane section of the stress-strain curve,
sT
a(F-I corresponding to the yieldg appeared after 15 minutes, and grew
further in samples annealed for 40 and 60 minutes. The samples were

deformed by an OM-12 (IM-12) machine. Measurement results are presented
in Fig. 2 and in the table., The temperature dependence of the yield point
determines the temperature dependonoe of the resiatande to the motion of
free dislocations through the metal lattice. By subtracting curve 1 from
curve 2, the temperature dependence of consolidation with cold working is
obtained. The temperature depends linearly upon the stresses character-
izing the strength of the bond between dislocations and impurity atoms.

PERIODICAL: Fizika tverdogo tela, v. 4, no. 1, 1962, 8 - 13
TEXT: The effects of aging were studied after previous plastic deforma-
tion at low temperatures. The specimens, made of Armco iron with
0.03 - 0.04~o' carbon, were cylinders, 15 cm high and 10 mm in diameter,,
They were annealed at 6500C for 4 hr and cooled in the furnace. Deforma-
tion,was carried out on a 'W-12 (IM-12) machine at the rate of
-3 1
!:~3-10 sec-. Measurements were made on three series of specimens,
deformed at 20, -76 and -1960C, respectively. Aging temperatures were
20, _100 and 4000C, the latter in vacuo, Specimens predeformed at -1961C
showed lower resistance to subsequent deformation at 200 than those pre-
deformed at 200C~ In each case aging after low-temperature deformation had
a different affect from that when deformation took place at 200C. The
effect of low-temperature deformation is attributed to deformation twins

reaches room temperature. '.)ith subsequent deformation they cause
premature.flow, i. e. lowering of the deformation curves., Since twins
and microcracks have various different shapes, different stresses are con-
cantrated on them, which means that the metal will have no yield point..
The twins were revealed on. microphotographs of polished non.-etchea sectiorp-
Twinning produced by deformation at -1960C has the sam,_ effict on sub-

'AB ST RACT: Stress patterns which develop in steel* M25YU5 and tungste'ri during

strength of steel was considerably lowered (2h-29%). This was explained by the
action of concealed stress 6oncentratorb (intergranular boundaries). It was con-
cluded that twinning was responsible for the failure oflKh25W steel at _196K. The

ABSTRACT: rn order, to fill gaps in the literature, tests were underWcen in which
cylindrical specimens, 8 mm, In diameter and 12 mm high of technically pure Fe (0. 0034%
C), Mo (99.9% Me) and Ta (99. 11% Ta, 0. 63% Nb) were vacuum-tempered at 900 K for
two hours (Fe) or at 1100 X for one hour (Mo and Ta) and compressed in an IM-12A
machine at 77 (liquid nitrogen) or 300 K up to 40% of their Initial height.,, For all the
metals, the curves relating 66Ti 11,c and the degree of detormation show on otherwise
uniform patterns, an upward trend with increasing deformation. Control studies showed
that no fatigue, which might have affected die yield stress and Interfered with tempera-
ture dependence tbsts, occurs during the 77-300 K transition. Of the curieTit theories
proposed.-to, expl-ard the mechanism of the dependence, the. authors believe that a stepwise

ABSTRACTs The au 0
method for determining the tendency of metals toward brittle fracture. The method
is baned upon the varying influences of a scratch or incision on the strength
of a brittle or plastic substa'ce. When the original condition of a
n
teat material is known and when the results of tensile tests on a smooth and a
scored sample are compared, the material's resistance to fracture can be determined.
The au -thor defiried the critical temperature of,,brittleneBa an that temperature at
which transition from fracture along the incision to fracture along the'Bmooth
portion takes place. The test specimens were'deBeribed and shown in two viewB% the'
-666bthpart of,the sample shaft had a diameter of 3-5 mm; the incision groove was
.~cut with a radi~a of 0.2 mm and a depth of 0-5' mm. Testing machine 111-4 was used in
Ij.,Bpecimexx deformation, and testing too7-c,place through a temperature interval of
1/9 --- ---
'~"20 to -196c. The difference between the two typea of fracture discussed was shown
in a photograph;of two fractured samplasp one-fractured at 20C and the other at
196C. The author urged careful control of experiment execution and measurements to
.I.minimize extraneous influencea upon critical temperature determination. Orig. art.
