The electrostatic field intensity near the surface of a geophysical rocket launched
15 Nove'mber'l961*as- measured by means of.-an electrostatic fluxmeter.
The equipment measurement range was � 6 vkml The readings of two symmet-
rically placed fluxmeter pickups, although differing from each other, showed
that field intensity undergoes relatively slight variations with altitude. The in,
tensity value measured by one of the pickups varied within the range of 0.5 to
1 v/cm, and that ofthe other from 1.8 to 2.5 v1cm. The second pickup was il
ne sun at an angle of 4* throughout the flight, while the first re-
luminated by t.
mained in the shade. The electric field intensity corresponding to the charge
on the rocket itself had an average value of 1.5 v/cm. After taking into account
measurement errors and inaccuracies in the determination of the real value of

TITLE: On the Effect of Light Plastic Deformation on the
Secondary Recrystallization and on the Formation of
Texture in Cold-Rolled Transformer Steel
PERIODICAL: Fizika metallov i metallovedeniye, 1959, Vol 7, Nr 4,
pp 631-632 (USSR)
AbSTRACT: It has been shown (Ref I and 2) that the formation of
texture during annealing of cold-rolled transformer
steel is associated with the secondary recrystallization.
The most perfect texture is formed at the temperatures
at which the secondary recrystallization begins (900 to
950*C), when the "nuclei of growth" are constituted by
most accurately orientated grains (Ref 1). The process
is comparatively slow at these temperatures, requiring
3 to 5 hours for its completion. The slow rate of
secondary recrystallization during high temperature
annealing makes it necessary to limit the rate of
heating and precludes the possibility of the application
of fast methods of annealing (induction heating,
annealing in conveyor furnaces). The object of the
investigation described in the present paper was to check
Card 1/5 the claims made by Umanskiy and Finkellshteyn (Ref 3) that

Transformer Steel
the secondary recrystallization can be accelerated
if the metal is slightly deformed before the high
temperature annealing. Transformer steel of the usual
composition (0.012% C, 3.10% Si, 0.095' Mn, 0.005% S,
0.01% P) cold-rolled to 0.35 mm thickne:s and showing
clearly a tendency to secondary recrystallization
completed in 4 hours at 9200C, under which conditions
clearly pronounced texture, reaching 90 to 95% oriented
grains, was formed, was used in the experiments.
Preliminary experiments showed that low temperature
annealing (i.e. below the temperature at which secondary
.recrystallization begins) has no effect either on the
parameters of the secondary recrystallization or on the
final texture formed during subsequent high terriperature
treatment. The experimental specimens, annealed for
2 hours at 8000C, were cold-rolled to 2-5, 5.0, 7.5 and
10*0 deformation and then annealed at various temperatures
between 700 and 11000C. It was found that no secondary
Card 2/5 recrystallization had occurred in any of these specimens,

in which the normal recrystallization only took place.
The grain size was determined by the degree of
deformation and the annealing temperature, the largest
grains being obtained in specimens with 2.5 and .5%
deformation atincalod at 750 to 6000c; increasing the
annealing temperature or the degree oC deformation
resulted in the reduction of the grain size after
recrystallization. It should be mentioned here that
in specimens with the critical degree of deformation,
faint texture was formed during annealing, even in those
cases when the recrystallization led to the formation of
grains of maximum size. In this case, texture did not
exceed 20 to 2570' (i.e. the magnitude which is observed
in material annealed below the temperatures of
secondary recrystallization). it has been shown,
therefore, that subjecting the specimens to critical
deformation not only did not accelerate the secondary
recrystallization but retarded it, substantially lowering
Card 3/5 the final degree of the perfection of texture. The works'

trials conducted in the plant "Elektrostall"consisted
of the following: transformer steel, cold-rolled to
0.53 mm, was annealed in a conveyor furnace at 9500C,
the conveyor ipeed being 3 m/min, which corresponded
to 2 minutes' holding of the metal in the heating zone;
after this treatment the strip was cold-rolled to the
final thickness of 0.5 mm and annealed for 4 hours at
11500C in a bell furnace; another part of the same
consignment of steel was fabricated in the form of
Strip 0.5 mm thick by the usual method i.e. without
the application of the critical deformation before the
final annealing. The properties of these two types of
materials are given in the table on p 632 under the
following headings: treatment (with the application of
critical. deformation; by the normal method); the
direction in which the test piece was cut out from the

ABSTRACT: The application of textured silicon steel (cold rolled
transformer steel) for shielding communication main
cables and wound magnetic circuits called for improved
plastic properties of that steel. Plant "Ellektrostall"
(zavad Elektrostall ) carried out experiments with the
above steel containing Si, 3.17; C, 0.03; Mn, 0.08; P,
0.007; and S, 0.007%. A piece of 0.5 mm. thick strip
was obtained by double cold rolling of 2.5 mm thick
strip with intermediate recrystallization vhen strip
was I mm thick. Subsequently, it was annealed for 6
hrs at 1,2000 C. Since plasticity of such specimens
was low (it could be bent only once) subsequent experi-
Card 1/4 ments concerned various heat treatment methods to

treatment consisted of'heating to 1--,00-1,0000 C, holding
for 2 min and water quenchin~r. il
Highest plasticity was
achieved when quenching from 6000 -
CD C which regulted in a
maximum number of bends IFig. 2). This increaoe of
k
plasticity laith a corresponding decr~-ase of grain

plus carbide. Hence, the structure of sirip annealed at
high temperature is characterized by an acciunulation
of the carbide phase. As a result of heating such
strip to temperatures below the transformation point,
i.e., below 8000 C, the carbide phase dissolves in
a -iron. This state of solid solution is set by
subsequent rapid cooling. The determined optimal
temperature rates of heat treating were used for
plasticity increase of high temperature annealed

industrial batches of transformer steel. For this
purpose a muffle furnace with approximately 6 m'long
heating chamber and a 9 m long cooling chamber with
water cooled hollow walls was used. Dry hydrogen was
fed continuously to both heating and cooling chambers.
The rate of strip travel in the furnace was 3 m/min.
The temperature of the external wall of the muffle was
8500 C to compensate the temperature gradient between
the external wall and the strip.' The tests of no bleat
treated preliminarily annealed (for 6 hrs at 1 ,100 C)
batche.~~ of industrial 0.5 mm, thick transformer steel
strip showed considerable increase of its plasticity.
