heating ( - 500C /hr) to a temperature of 1000 - I 2000C, the intensity of the TR and
the magnetic characteristics 6f the steel were quite high; similar TR and properties
were obtained at greater rates of heating only within certain narrow temperature in-
tervals which varied for different smeltings. It is noted that the rate of cooling has
little effect upon the properties of a steel; however, rapid cooling of specimens
results in considerable specific losses during subsequent aging of steel at a tempera-
ture of 1000. Optimal soaking time or the optimal rate of drawing was established
for the maximum annealing temperature in continuous and intermittent furnaces. The
mechanism of the formation of the TR is also discussed.

induction characteristics exhibited a high DPRT in the planes (110)

ABSTRACT: The increase of the speolfic lose for an induction of
10 000 Gauss is insignificant (a few percent) whilst
at 15 000 Gauss it is appreciable (over 5 to 10%) and
this phenomenon is explained by Spuner, T, (Ref.2) by
the differing permeability of the scale in nzedium and
strong raagnetic fields, However, direct investigatioru,
of the magnetic properties in 8uch steel have not been
carried out and,, therefore. this was done by the autho!-
ofthis paper. The authors have chosen sheets of
unpickled dynamo and transformer steel sfter the no=.a-2
process of rolling and annealing at 850 C; from each
sheet strips of 250 x30 mm weighing about 1 kg were cut.
After testing the mechanical properties, the scale ras

which common salt was added rihich stopped almost entirel-,-
the dissolution of the metal itself (less than 2 grams).
The specific gravity of the pickled and the unpickled
steel as well as of the scale and also the Si contents
of the respective steels are entered in Table 1. The
magnetisation curves without scale, with scale and of
the scale itself are graphed in Fig.1 for dynamo steel
and ~n FiG.2 for transformer steel. Fig-3 gives the
hysteresis loop for dynamo steel without and with scale;
the change of the total specific losses and the
hysteresis losses during pickling of electrical steel
are entered for four specimens (Si contents I to 4%)
for 10 000 and 15 000 Gauss In Table 2. Table 3
contains data on the thickness and the specific electric
resistance of the scale of electrical steel (1 and 4% Si).
The obtained results lead to the followinG concl,-sions:
1) In the investigated sheets of hot rolled dynamo and
transformer steel the decrease in the spegific weight
due to the presence of scale is 0.06 g/cm2, the specific

2) The permeability of the scale in weak- magnetic fields
(up to 0.2-0.3 AT/cm) approaches that of steel., whilst

is considerably lower than that of steel. Tbe B 300 of

PERIODICAL;Vextnik elektropromyshlennosti, 1959c, Nr ~,, pp 41-43 (USSR)
ABSTRACT: When the apparatus is used to determine iron
loss In low-lo.-. steel., the result is affected by work.-
hardening of the samples during cutting. The new
standard GOST 802-38 requires that before samples of
cold-rolled steel are tested on th, '~ -, : ipparatus
they should be heat-treated at a temperature of 750 to
800"C for two hourA in a suitable atmospheze. It is
assumed that the redu--.tion in loss that o-curs is due
only to relief of work-hardening produced during cutting
of the specimens. This article shows that there are also
structural changes in thq ateel during ihe heat-treatment
and that they 4-.ontribute to rhe reduction in the losses.
The reductions due to relief of work-hardening and those
Card 1/3 due to other structural changes were sspacatBd in ths

following way. Samples were cut for the test
and their losses determined. Then they uer-i~ h,at--
treated at 7500C for two hours and the lo-eses rp--determined.
Next strips about 1 mm wide were cut off each edge and the
losses determined a third time with due allowance for the
change in weight. The differpnze between the first and
second loss-determinations is the total reduction in
losses caused by heat-treatmenti the difference between
the third and second determinations is the inz-rtase in
the losses caused by work-hardening during shearing of
the edges. It will be seen from the results of
measurements on nine samples of cold-r-,>lled uteel given
in table I that in samples -with low Icsses (less than
0-7 W/kg) nearly all the change in loss on heat-treatment
is due to removal of work-hardening. Hcweve~r-, in sheets
with losses greater than 0.7 Wlks the rtduzt.-on in loss
on heat-treatment may be two or three t_-mes that saused
by work-hardening. This differan-:.t must b3 attributed

hysteresis loss and coercive forcr-. (see tabl-3 2). It is
explained that these changes are princApally asscciated
with further detarbonination zf tht- samples and with the
relief of remanent stresses left in the -9heet after heat-
treatment. The presence of remanent streas in the
sheets may be demonstratod by tutting them along the
direction of rolling, which scmetimia reduc6s th* 1csses
and coarnive force as will be seen from ihe results
given In tabl,5 .3 xhich also givs loss r-sults on narrow

misleading results and that it is b-~st to msk~~

ABSTRACT: Silicon embrittlee steel. Its action is enhanced by the
influence of the carbide phase (Refs 1-3) and of temper
brittleness (Ref 4). As the crystals of steel used for
electrical purposes are more or less orientated, then,
owing to anisotropy in the mechanical properties of
monocrystals of Biliceous ferrite, there must also exist
anisotropy in brittleness, No data regarding such aniso-
tropy in brittleness for the above steel are available.
Steel for electrical purposes is hot-, as well as cold-
rolled. The orientation of crystals of hot-relled steel
is weakly preferential, and that of cold-rolled, strongly
preferential. As the determination of the crystallo-
graphic texture of hot-rolled steel presents considerable
difficulties, the author used an indirect, magnetometrie
method. The texture of steel can be judged from the
Card 1/4 nature of the mechanical moment curves obtained f or a

disc-shaped specimen. If the curve takes the shape of
that shovin in Fig 1, then the crystals of ordered
orientation will be orientated as shown in Fig 2. If the
mechanical moment curve is similar to that shown in Fig 31
then the orientation of crystals will be as shown in
ig 4. The first type of text expressed as (100),

type of texture, the L1100 grain a6onals of textured
crystals are situated along, an a 4 angles to, the
right
rolling direction; at a (110), 1 - type of texture, the
Looe~ 1 es are disposed along th-e rolling direction, and
ro'111110 axes at right angles to it. The texture of hot-
ynamo steel is more pronounced than that of
transformer steel, and is more complex. The harmonies A 2
and A can be used to evaluate any change in te ture.
For ehinplo, the amplitude of A2 for a (100), C1101 -type of
texture must be zero, and A4 must have a positive value.
As A4 decreases and A2 increases, the texture will
Card 2/4 increasingly tand to change to the (110) 1 [100] type. The
SOV/126-7-2-18/39
Anisotropy in the Brittleness of Silicon Sheet Steel
texture, which in hot-rolled dynamo steel attains approx-
imately 25%, can be quantitatively evaluated from the
mechanical moment curves. In cold-rolled transformer steel
the crystals having a prefezred orientation of the type
(100), [100] occupy 70-". by volume of the total number of
crystals. Sheets of steel from industrial batches were
used for the investigation. Where required, discs for the
determination of the crystallographic texture were cut out
from the same sheets. In the case of cold-rolled steel,
part of the investigation was carried out on monocrystals
specimens. In Table 1, dat-a on the dependence of brittle
anisotropy on crystallographic texture in specimens of hot-
rolled dynamo steel are given. In Table 2, data on brittle
anisotropy in specimens of hot-rolled transformer steel gre
given. In Table3 data on the number cfbends (through 90
for transformer steel specimens cut out along the rolling
direction at right angles to it, with ardwithout carbide
inclusions, are given. In Table 4, data on the brittle
anisotropy in polycrystalline SDecimens of cold rolled steel
are given. In Table 5, data on Lhe brittle anisotropy in
Card 3/4 specimens of cold-rolled transformer steel are given. As a
result of the above experiments, the author has arrived at
SOV/126-7-2-18/39
Anisotropy in the Brittleness of Silicon Sheet Steel
the following conclusions:
1. An anisotropy in brittleness exists in cold-rolled, as
well as in hot-rolled, steel.
2. In hot-rolled dynamo siteell a direct relationship exists
between the anisotropy in brittleness d the texture of the
steel. For specimens having a -100 - type of texture,
0(110)? r
the number of bends through 90 possible along the direction
of rolling is twice that at.right anr-les to it.
3. The number of bends possible for cold-rolleg transformer
steel specimens, cut out at an[~les of 0 and 55 to the
direction of rolling, is 2.5 - 4 times greater than for
specimens cut out at right an6les to the direction of
rolling. The difference in the number of bends for
specimens, cut out at an6les of 55 and 900 to the direction
of rolling, is proportional to th-1- distances between the
cleavage planes. There are L~ fiE;ures, 5 tables and

PERIODICALt Fizika metallov i metallovedeniye, 1959, Vol 8, Nr 6.
pp 892-895 (USSR)
ABSTRACT: In Soviet-made dynamo steels conforming to GOST 802-58
(types E 11, E 12, E 13, E 21 and E 22) hysteresis
accounts for most of the core losses. Doroshek has shown
that alloying with phosphorus is known to reduce core
losses by increasing grain size and resistivity and
changes the gamma-range so that high-tqmperature treatment
can be used (Ref 3). In the present investigations the
components of the core losses of dynamo steel (1.8% Si.
0-03% C) containing 0-03, o.06, 0.12 or 0.36% P were
studied. 0.5 mm thick sheets made by forging and hot
rolling from 35 kg induction-melted billets, as at the
Verkh-Isetskiy works, were used. 250X 30 x 0-5 = Platesp
assembled in kg packets were vacuum annealed at 850, 930,
1050 or 11504C for 4 hours and then cooled in the furnace
and tested. Coercive force is shown as functions of

850s 950 and 115000 (curves 1, 2 and 3 respectively) i
each curve falls with increasing P-content, the slopes
of curve 3 being appreciably less than those of the
others; for a given P-content the coercive force
decreases with increasing temperatures. The number of
grams per MM2, resistivity, total core losses and its
components are shown in Table I for 0.03% P steel annealed
at 850, 950 and 1150*C. Tables 2 and 3 give corresponding
data for different P-contents and annealing temperatures
of 850 and 1150*C respectively. Increasing phosphorus
content lowers the hysteresis losses on account of
increasing grain size, and eddy-current losses on account
of increasing resistivity. Fig 2 and 3 show, respectively,
the initial and maximal magnetic permeabilities as
functions of phosphorus content, for 850, 950, 1050 and
1150 OC annealing temperatures (curves 1, 2, 3 and 4.

PERIODICAL: Zavodskaya Laboratoriya, 1959, Vol 25, Nr 4, PP 429-433 (USSR)
ABSTRACT: For tests of specific losses (SL) on narrow metal strips which
are carried out to judge the SL on whole plates according to
GOST 802-58 for steels E 310, E 320p E 330, and E 370, a second
tempering of the narrow strips is added. Problems in connection
with this standard method for tests of electrotechnical steels
are described in the present article. In the chapter on the
form of samples for steels destined for the manufacture of large
magn'et conduotors it is pointed out that, on one hand, ar. in-
crease in the SL is caused by the cold hardening (of the cut-
ting process) in cutting the plates into narrow strips, and on
the other hand, a decrease in the SL is caused by the slackening
of the elastic residual tensions of first order. The larger the
Card 1/3 distance resulting from cutting, the more will the SL values
SOV/32-25-4-20/71
The Form of Samples for the Dete=ialnatiora of Magnetic Characteristics of
Electrotechnical Steel
change (Table 1). The second tempering of the ~,ut metal strips
prescribed by GOST 802-58 causes a decrease in the losses with
reference to the cold hardening of the borders, as well as an
additional decarbonization and a slackening of residual tensions
(as compared with the whole piece of sheet metal), The increase
in the loases by cold hardening is OoO5-0-08 watt/kg, while the
VA,
iecrease in the losses by the hardening attains 0-15n%18 wat".9
(Table 2, values for 8 types of steel), while a second tempering
of the whcle plates (at 750-3009 practically does not reduce
the SL (Table 3, valaes for sheet metai and metal strips of 6
types of steel). On account of this the SL values for electro-
technical steels to be used for large magnet conductors must
absolutely be determined on whole plates. Equally good con-
ditions as are obtained with the apparatus according to Epstein
can be obtained by the magnetization of four metal sheets which
are superposed between two solenoids and are joined with each
other at the ends (Fig 1). The determinations of the SL and of
the magnetic induction (according to � 57 in COST 802-58) are at
present carried out on metal sheeitb as a whole or cut in two
Card 2/.3 halves,by the Verkh-Isetskiy metallurgicheskiy zavod (Verkh-

maGnetic induction on ring samples of two steel types destined
for small magnet conduotorsy after Qne stamping and a second
tempering in different agents. Thp difference of the values of
magnetic induction at hardening in different agents is 20-30%.
The values of permeability of a transformer steel before and
after a second tempering (at 600-7500) in an oxidizing agent
differ by 2-3 times (Table 5, values for 3 steel types). It is
recommended to establish the magnetizing curves of the steel

magnetic properties of transformer steel

TEXTs Use of the powder pattern method to study transformer
steel showed that in fine-grained sheet steel the domain size is
5-10 times smaller than in coarse-grained. The presence of
non-metallic inclusions in the steel causes the formation of
additional domains which retard the processes of magnetisation
and demagnetisation, and also make the domains smaller and
curve the boundaries between them. Irregulariiy of magnetisation
was observed between the grains and within the grains and this
-may be one of the causes of increased eddy-current losses in
coarse-grained electrical sheet steel.

ABSTRACTt
Card 1/3
Druzhinin has previ-usly shown that there is a
considerable crystallographic texture in hot-rolled
dynamo steel leading to appreciable magnetic anisotropy
(Ref 1) which can be in either of two directions. In
the present work, the authors have studied this effect
in different sheets from packets rolled in various
ways at the Verkh-laetak Metallurgical Works (two of the
rolling procedures are shown in Fig 1 and 2; the third
being different in that it did not involve doubling).
Sheets were rolled to a thickness of 0-5 mm from 10.2 in
eleven passes. For studying texture, 40 mm diameter
discs were cut from each sheet and their moments
determined magiltometrically with an inter-pole field of
3000 oersted. ,.Snetization was effected at various
angles to the dA-ection of rolling (Fig 3, 5 and 6 show

moment as a function of the angle for rolling by
procedures 1, 2 and 3 respectively). Anisotropy of
magnetic-induction was studied on 250 x 30 mm strips cut
out at various angles to the direction of rollingi Fig 4
shows magnetic induction as a function of this angle. The
authors conclude that crystallographic texture anisotropy
is due to sheets being doubled during rollin Rolling
