“…Upon further heating for PR, new Goss grains grow from regions containing mesostructure elements (twins, transition bands, shear bands). After the com pletion of PR, the Goss orientation dominates in the material [4,6,7]. Based on the previous investigations [7], it can be assumed that nuclei that arise at defor mation twins possess the most perfect Goss orienta tion.…”

“…This occurs due to the transformation of the poor goss orientation into more perfect octahedral orientations [4]. In the process of subsequent annealing, following PR, mainly nucleation mechanisms operate, which are connected predominantly with shear bands and tran sition bands.…”

“…The technology of its produc tion involves cold rolling of strips of a coarse grained (5-30 mm) grain oriented electrical steel (GOES) with a perfect cube on edge (Goss) texture ~0.3 mm (or smaller) thick and subsequent annealing for pri mary recrystallization [1]. To date appreciable interest in the mechanism of the formation of the texture that determines the unique properties of this product is retained [2][3][4].…”

Abstract-The effect of the copper content, initial structure, and scheme of treatment on the magnetic proper ties of an ultra thin grain oriented electrical steel has been investigated. In the material with copper and an initial sharp texture, the nucleation of new grains upon primary recrystallization is connected with deformation twins; in the samples without copper and with copper and diffuse texture, it is connected predominantly with shear bands and transition bands. Upon heating at a rate of ~0.004 K/s, the temperature of primary recrystallization in the copper bearing samples is considerably higher than in the copper free material. Upon heating at a rate of 4 K/s the appearance of new grains occurs almost simultaneously for all of the studied samples. In the samples with copper and initial sharp texture after annealing at 1050°C, a significant part of the volume is occupied by grains that had undergone normal grain growth; in the samples without copper and with copper and diffuse tex ture, anomalous growth is hardly observed at all. To obtain high final magnetic properties of the ultra thin grain oriented electrical steel produced by the Littmann method, it has been suggested to use an grain oriented elec trical steel with 0.5% Cu that exhibits the diffuse orientation of grains as the workpiece.

“…Ultrathin (less than 150 μm) grain‐oriented silicon steel is an important material used for high‐frequency transformers, pulse transformers, inductors, and so on and has drawn great interest from researchers due to its high permeability and low iron loss. [ 1–3 ] At present, primary recrystallization and tertiary recrystallization methods have been applied to produce ultrathin steel respectively based on the ‘texture memory” and “surface energy induced secondary growth” of Goss orientation. [ 2–5 ] In these processes, commercial grain‐oriented silicon steel products were selected as the raw materials.…”

Herein, four kinds of initial Goss textures with different deviation angles (0°, 5°, 10°, and 15°) are obtained by controlling the included angles between the longitudinal directions of rectangular cutting specimens and the initial rolling direction of the raw material. Then, 0.05 mm thick grain‐oriented silicon steels are fabricated by cold rolling and primary recrystallization annealing. Effects of initial textures on the microstructure and texture evolutions and magnetic properties are investigated in detail. Compared with sharp {111}<112> in the cold rolling sheet with initial exact Goss, the deviated Goss favors the formation of strong {111}<112> + weak {h11}<1/h 1 2> textures. After annealing, sharp {210}<001> + medium {110}<001> textures develop as a result of the small initial deviation, while larger initial deviations contribute to the {310}<001> texture. In addition, the average grain sizes are also related to recrystallization textures. Consequently, the distinct recrystallization microstructures and textures result in the differences of magnetic properties.

“…In other words, the slip processes, which resulted in the rotation of the lattice about the TD and ND axes, occurred even in the bands whose orientation was relatively close to a Goss orientation (А and С). The mechanism of this reorientation of the crystal lattice (110)[001] somewhat deflected from the ideal orienta tion is presented in [16].…”

Abstract-A transition band between two deformation bands retains for the most part the orientation (110) [001] and shrinks to a thin interlayer or boundary with increasing degree of deformation. At a certain stage of deformation, the microvolumes that are arranged along the interface of the bands become adjusted to special misorientations. During primary recrystallization, cube on edge (Goss) grains, which grow from the transition band, have portions of special boundaries common with the deformed matrix; these boundaries were found earlier between the deformation bands. This indicates that the local domains with special misori entations formed at the stage of cold deformation transform during annealing into the corresponding pri mary recrystallization nuclei.
