ABSTRACT: Optical methods were employed in studying the degree of com-
pleteness of recrystallization texture (DPRT) in production batches
of steels E310 and E330. It was established that the DPRT affects
the magnetic properties of steel. Specimens possessing high magnetic-
induction characteristics exhil%*ted a high DPRT in the planes (110)
[100] , the [100] plane in the plane of rolling deviating from the
direction of rolling by � 50; specimens with poor magnetic properties
exhibited a (100) (1001 texture rotated by � 10-150 within the plan'e of
rolling

ABSTRAM The hypothesis of Druzhinin-and Kudryavtsev (Refs 1,2),
asserting that in cold-rolled electricaJ steel a spread
of the orientations o 'r the tetragonal axes [1001 With
respect to the rolling axis is observed, permits the
construction of a model. of cold-rolled electrical steel
on which it is possible to study the charactc-trisLics.
The model is in the form of two monocrystalline discs
superimposed on each other-, these have the following
crystallographic orientation., the plane (110) lies in
the plane of the disc, while the direction F1001 js
selected an the surface of the disc. The d"iscs are
obtained from the standard industrial cold-rolled steel from
which it is possible to grow grains having a transverse
Cardl/5 dimension of 3 cni by nteans of a prolonged heat treatment.

The Problem of Determining the Quality o e eX ure of
Polycrystalline Ferx-omagnetics
The crystallographic uniformity of the grains is
determined by the optical method (Ref 4). The anisotropy
of such a system of discs depends on the angle IV
between the directions L1003 of the individual discs.
If Y = 0 , the sample behaves as a monocrystalline disc.
When kV is increased, it is possible to simulate various
degrees of texture quality of the sample. It is necessary
to find the relationship between the disperions of the
-angl-e----W-- and the amplitude of the harmonics of the
mechanical-torque curve of the sample and to verify the
following formula (Refs 2, 5) which was derived by another
method:
A = nb c o s n a (1)
n n LY
In this equation A n is the amplitude of the n-th
harmonic of the medunical-
torque characteristic,
b is a linear function of the constants

the dispersion cr IV is defined by Eq (3), whore QL
is the relative volume of each disc which in equal to 1/2
It is assumed that the mechhnical-torque characteristic
of one of the nionocrystalline discs is expressed by
(with an accuracy to 4 terima)j
M = A2 sin 2y + A 48 in4y + A6s in6y + A8s in8y (4)
In this A 21 A4' A 6 and A 8 are the amplitudesof
the harmonies and y is the angle between a gkven
direction at the sLrface of the disc and the external
magnetic field. If two discs are combined at an angle
Y , the resulting torque is expressed by Eq (9). This
can also be written as Eq (10) . where B B , B and

amplitudes are expressed by Eq (11) but since
Y/2 = ofy , the amplitudes are given by:
Bn = Anc o 9 n o~. (.12)
However, according to Kudryavtsev and Giglin (Refs 2, 5),
An = nbn . Consequently, B n can be expressed by Eq (13).
In practice, the characteristic of the mechanical torque
of the system of two monocrystalline discs, whose torque
characteristics are known, can be constructed graphically,
Such a curve is shown in Figure 2, in which the "solid"
curve represents the resulting mechanical torque

amplitudes B. abd B4 of the torque characteristic on

which were obtained by means of the Akulov magnetometer.

Crystallographical Texture in the

1960, Vol. 3, No. 3.
TEXT: The investigations described here were carried out on a transformer-
sheet, the composition of which Is giveng and which had been produued at
the Novo-Lipetskiy metallurgiohetikiy zavod (Novo-.Lipetak Metallurgicail
Factory). Cold-rolling was carried out in two variants. In the case of the
first the individual reductions per working operation were 2 - 3%, in the
second they were 20 - 30fo- Measurements of the moment were made by means
of the magnetometer developed by N. Akulov (Ref. 2), In Fig. I moment-
curves for various total reductions are shown. Prom the discussion of these
curves it follows that because of the symmetry of the rolling processq the
intermediate layerg which in samples of more than 0.75 mm thickness, occurs
beside the middle- and the surfaoe layer, is characterized by a oonsiderable
dispersion of the crystal surface (100) round the direction of rolling.
Proceeding from the distribution function (2) for the orientation of the

grainag At is shown that the structure of the intermediate layer is not per-
footly axial. In the oase of high deformation rates cracks form at the
boundaries of the layers, and in Fig. 2 a sample is shown, in which a
oraok was caused by too high a rolling rate. Here deformation in one
travel amounted to 60%. The difference in the structure of the layers is,
as experiments made by annealing at 8000C in hydrogen atmosphere showed,
not fully removed, even after annealing for 10 hours. Fig. 4 shows graphi-
cally the influence exerted by thermal treatment on the curves of the
moment. Annealing, as shown by these diagrams, practically influencea only
the course of the moment-curve of the middle layer. There are 4 figures

ABSTRACT: In this letter to the editor the author briefly develops
his previous observations (with Druzhinin - Ref 1) on
the distribution function for grain orientation in industrial
cold-rolled electrotechnical steel. He deduces an equation
relating the amplitudes of mechanical-moment harmonies- to
functions of the angle between direction of rolling and the
[6611 direction. Valuvs calculated for various steels are
tabulated together with t1vose found optically (Ref i).
There are I table and 4 references, 3 of which are Soviet

TEXT. The problem of non-uniformity of the texture along the
cross-section of cold-rolled materials has so far been little
studied. Of greatest interest in this respect is the work
published by Mailer and St9blein (Ref. 1) who also investigated
the nature of scattering of the crystallographic structure in
the centre, and in the neighbourhood of the surface, of cold-
rolled silicon iron (total reduction 92%). They found that
although the type of texture in these layers remains unchanged,
the scatter in the texture along the layers differs in
character. whereby the highest amount of scatter is observed
in the external layer. The increase in the scatter of the
texture in the external layer should lead to a decrease in the
magnitude of the mechanical. moment generated by a rotating

magnetic field in the external layer after separating it from
the cold-rolled material (for instance by etching) as compared
to material from the internal layers. This phenomenon has been
experimentally observed by the author (Ref, 2). Apparently the
relation governing the changes along the layers of the mechanical
moment can be derived from the character of the distribution
of the orientation of the crystallites of the cold-rolled
material in a manner analogous to that obtained for industrially
produced cold-rolled electrical steel (Refs- 3, 4)~ It is
shown that the dependence of the intensity of reflected X-rays
I on the angle y between the normal to the rolling plane and
the normal to the crystallographic plane (200) corresponds to
the function of the distribution of the orientation of the
grains p(y) with an accuracy of up to a constant coefficient,
A concrete form of the function I(y) for the internal and
external layers of the cold-rolled alloy is given in a figure
for the case of a total reduction of 92%, The relationship

between the function p(y) and the curves of the mechanical
moment can be determine-d by finding the analytical dependence
of the harmonic amplitudes A2 and A4 of the mechanical
moment on the shape of the function p(y) . For this purpose, it
is assumed that the mutual position of the 3 tetragonal axes and

TITLE: Compensation of the Mechanical
Mom nt n the Case of Cubic Texture of Transformer
Ste:l ~1
PERIODICAL: Fizika metallov i metallovedeniye, 1960, Vol.10, No-5,
pp.661-667
TEXT: There is a non-equivocal relationship between the spatial
distribution of the orientation of grains and the curve of the
mechanical moment H(* ), where '* is the angle between the
magnetization of the specimen and direction of rolling. Although
the shape of M(V) is equivocally determined by the texture of
the material, to each M(V) curve there may correspond several
types of scatter of the orlentation of grains. Consequently,
MOCE 0 is only a necessary condition for the absence of texture.
It has been shown by Bryukhatov et al (Ref.2) that in a nickel
specimen which, at a given stage of the treatment ~ad M(-f) S 0,
well pronounced cubic texture of recrystallization%Ddeveloped after
annealing. The obvious inference is that this compensation of the

Case of Cubic Texture of Transformer Steel
mechanical moment is associated with certain specific features of
the scatter of the texture which have not yet beon investigated.
Consequently, the object of the present investigation was to study
the distribution of orientation of grains in specimens of
transformer steel, characterized by a cubic texture and
M('V) S 0, and to show analytically that a specimen with a given
distribution of the orientation of grains should, in fact, have
M(V) S-0. A steel, containing 2.47% Si, 0-07% C, o.4% mn,
OA31% P, 0.028% S, 0.06% Cr and traces of aluminium, was used
in the experiments. Hot-rolled strip (120 x 60 x 5 mm) was
col'd-rolled to 0.96 mm thickness, annealed at 800*C for 1.5 h,
pickled, cold-rolled again to 0.25 mm thickness and, finally,
annealed in hydrogen at 12000C for 12 h. Back-reflection X-ray
technique was used to study the texture of the specimens whose
M(~F) at room temperature was determined with the aid of a rotating
magnetometer in fields of not leas than 3000 Oe. Specimens,
annealed for various periods shorter than 12 h, were examined in

the same manner. The results indicated that variation in the
distribution of orientation of grains (with no change in the type
of texture) can be accompanied by qualitative changes in the
anisotropy of the mechanical moment so that, even in the case of
pronounced cubic texture, conditions may exist when M(V E 0.
It was concluded that when the processes of texture formation are
studied, the magnetic method should be supplemented by more direct
methods of determining the texture. Acknowledgments are made to

TEXTi An analysis is made of the applicability of Bitter's
method (determining the texture in sheet materials from the
amplitude of harmonics of mechanical torque curves, which are
communicated to a disc-shaped specimen in a uniform magnetic
field) for weakly-expressed -textures. For commercial transformer
steel there is a good agreement with experiment, so that the
method can be used for industrial control of the extent to which
texture is developed in such steels. It is shown that Bitter's
equations are not inconsistent and that they can be used to
explain why analysis of magnetic texture is not single-valued when
the texture is very clearly expressed. 12 literature referenceso

TM-: The problem of representing the free energy of a ferromagnetic
crystal by a series of direction cosines and that of the decrease of the aniso-
tropy constants in the series with an increase of their ordinal number are
considered. The experimental relations between-crystal symmetry and free energy,
which are given, prove the correctness of conclusions, based on the relativistic
quantum theory, regarding the dependence of the magnitude of anisotropy constants
on their ordinal number.

TITLE: On textural non-homogeWty along the sheet cross section of cold-

TEXT; The original specimenli of commercial N1, 2 mm thick, obtained from
ingots by combined hot and cold rolli -ng, were subjected to recrystallization an-
nealing at 8500C for 5 hours. The cold rolling was carried out both directly and
reversibly (the specimens were always inserted with the same end into the rolling
rolls in the first case, and- alternately with -one and the other end in the second).
Using both these variants, the specimens were rolled down to total reductions of
10, 40, 50, 75 and 85%. Layers were- etched out of -the sheets obtained, parallel
to the specimen surface. The 15-20 mm diameter disks out out of these layers
were subjected to investigation. The qualitative variant of magnetic textural
analysis was at the basis of the investigation method of the specimen texture.
The mechanical moment was measured on a torsion magnetometer at room tempera~ture

in fields of not less than :> 3,000 oersteds. The A4 harmonic of the curve of
mechanical moment was utilized as the quantity defining the texture. It was es-
tablished that the amplitude of A4 drops sharply from the middle to the surface
of -the specimen, testifying to the moet intensely oxpressed texture being In the
middle layer and least pronounced'in the outside layer-, The pattern indicated
holds down to the very highest total reductions studied (85%). This result cor-
responds to the analogous data obtained earlier for transformer steel. By mans
of magnetic textural analysis it was -demonstrated that cold-rolled commercial Ni
possesses considerable magnetic non-homogeneity. In its effect upon the ampli-
tudes of the harmonies of the -mechanical moment curve, the magnetic non-homogene-
Ity of the specimens is equivalent to geometrical defects and wiihin the limits
of measurement errors has no influence upon the amplitude of A4. There are 10

channel of the IN-9 pump was also In the form of a flat slot with a section having dimen-
sions of 7 X 130 mm. Two longitudinal baffles were placed in the channel for the
purpose of evacuating the cavity of the pump. The inductor windings, in this case, had
a triangular connection arrangement. no IN-10 was fed through a 3-phaso current
transformer with the voltage regulated between 20 and 220 volts; the In-9 - from the
s,
220 volt AC three-phase not through a step-down transformer. The experimental stand
and the test technique are described In the article. The pumps were tested by con-
necting them to circulaUon BYBLOMS In the form of closed loops of tubing. The sodium
flow was measured by a magnetic flowmeter, the mercury flow - by means of a nozzle
with the readings transmitted to a manometer. A compensation manometer was used
in the measurement of the sodium pressure. 71io authors diacuns the rosidtS o t 0
testa In some detail. It was found that the IN-9 induction pump can be successfully
employed with laboratory sodium Instrtanentation for long periods at temperatures up
to GOOC. The IN-10 Is capable of protracted mercury pumping operations at a
temperature up to 100C and voltages up to 110 volts.. Design modifications are required!.

cal tube with a length of Oe5 meters and an outside diameter of 0 044
meters and made of Khl6Nl0T steel. The voltage on the leads of t~ebigb
frequency generator could be set within the limits of 0 to 750 volts*
Measurements were made of the power of the Eenerator, the voltage and
current strength# temperatures of the metal and the cooling medium at
the inlet and outlet of the indtictor,, and the feed rates of the metal
and the cooling medium* For tbe heavy alloy, the load on the generator
was varied within the limits of 25 to 80 kilowatts* Five series/V runs
were made with a total duration of 110 hours, The runs were made at a
constant rate of feed of the alloy equal to opproximately 201,000 kg/houri
Dcpending on the conditions, the temperature of the 9.1loy varied from
473 to 7730Ke For the light metal the load was 80 kilowatts,, the aver-
age temperature in thq hooter was approximately 11230K. and the feed
rate of the motalwas about 2,,000 kb/bour. The inductor 'was operated
under these conditions for approximately 150 hours, Results are shown

Influence of residual tensile stresses on the fatigue strength of smooth and notched
specimens (the author produced tensile stresses in the specimens by heat treatment.
The fatigue strength of the notched specimens were considerably lower if the notches
were made before producing the tensile stresses, but if these were made on a specimen
which already had residual tensile stresses these showed no adverse effect, probably due
to deformation in the affected zone).
