6n the Effect of Heating and Cooling Rates (cont. ) SOV/137-58-11-23400 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. A. B.

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 Card 1,14 removed by pickling in a 20% sulphuric 'acid solution to SOV/126-6-1-4/33 On the Inflnence of Scale on the Ma6netic Properties of Hot Belled Electrical Steel 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 Card 2/4 weight of the scale itself is 7.0 g/cm~' fo~ dynamo steel SOV/126-6-1-4/33 On the Influence of Scale on the Magnetic Properties of Hot Rolled Electrical Steel alid. 6.0 E;/cm3 for transformer steel. 2) The permeability of the scale in weak- magnetic fields (up to 0.2-0.3 AT/cm) approaches that of steel., whilst In medium and otron7, fields the pe.-meability of ~he scale is considerably lower than that of steel. Tbe B 300 of scale amounts to 14 000 Gauss for dynamo steel and 0. 000 Gauss for transformer steel, 3) Reduction of the full specific losses due to pickling; is insignificant at 10 000 Gaugs (0.10 W/kg for ayna-mo steel and 0.05 W/kg for transformer steel) and is due predo,ninantly to a reduction in the eddy current loose-c., The reduction of the full specific losses at 15 000 Gav.:;f-~ is greater, 0.5 to 0.8 W/k- for dynamo steel omd 0.2 to 0.4 W/kS fo:- transformer steel and is due tc, 9. reduction in the hysteresis losses as .:ell --s to a reduction of the eady current losses, The reduction in Card 3/4 the hysteresis losses as a result of pick."Ling is caused SOV/126-6-1-4/33 On the Influence of Scale on the Magnetic Properties of hot Rolled Electrical Steel by the reduction of the maximum magnetising field and not by reduction in the coercive force.

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 SOV/110--59-5--11/25 On the Procedure for Determining the Spe-;ifi:. Loss of Cold-Rolled Transformer Steel 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 Card 2/3 to structural changes in the atetl az.iompanied by reduced SOV/110-59-5-11/25 On the Procedure for Determining the Spe~nifir. Lcaq of C-,1r1--R-,_'1ed Transformer Steel 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 specimsns.

SOV/126-7-2-18/39 TITLE: -Anisotropy in th-C-Drittlonoev of Uilleou Sheet SteeI (0b util-"otrapil khrupkosti listovoy kreainistoy stali) PERIODICAL: Fizika Metallov i Metallovedeniye, 1959, Vol G. Rr 2, pp 278-283 (USSR) 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 SOV/126-7-2-18/39 Anisotropy in the Brittleness of Silicon Sheet Steel 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), tilog , and the second, as (lio urLICOS] . At a ( 100) , Clio) - )I 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.

TITIX: Components of Core Losses and Magnetic Permeability of Dynamo Steel~%Alloyed with Phosphorus 14 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 Card 1/3 phosphorus content in Fig I for annealing temperatures of 67668 SOV/126-8-6-16/24 Components of Core Losses and Magnetic Permeability of Dynamo Steel Alloyed with Phosphorus 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. respectively)t both permeabilities rise with increasing phosphorus content; in Fig 3 curve 4 lies below curve 3, but otherwise permeability at a given P-content increases Card 2/3 with increasing annealing temperature.

TITLE: The Form of Samples for the Determination of Magnetic Charac- teristics of Electrotechni-al Steel (0 forme obraztsov dlya opredeleniya magnitnykh kharakteristik elektrotekhnicheskoy stali) 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- SOV/32-25-4-20/71 The Form of Samples for the Determination of Magnetic Characteristics of Electrotechnical Steel IsetskiY Aetallurgical Works). Table 4 indicates values of the 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 types (Fig 2, E 46) E 45, E 46, E 47P E 48 and E370 at a sample arrangement in lap joint.

(Symposium "Magnetic structure of ferromagneticsll~ Novosibirsk, Sib. otd, AN SSSR, ig6o, 29-32) 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.

TITLE: Crystallographic TextureVand Anisotropy of the Magnetic Propertie! -Rolled Dyna o steel Hot Ii/ 1960, PERIODICAL: Fizika metallov i metallovedeniye, Vol 9, Nr 3, pp 353-357 (USSR) 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 69686 S/126/60/009/03/oo6/o33 E111/E452 Crystallographic Texture and Anisotropy of the Magnetic Properties of Hot Rolled Dynamo Steel 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 without reversing the texture type is (100~ Z109>; with reversing it is mainly (1101 with some (1061
