“…1e-1g). It naturally follows from the fact that the PR nuclei, 1 which are formed at the main mesostructure compo nents (deformation bands, shear bands, deformation twins), have a preferred Goss orientation and agrees with the earlier results [7][8][9][10][11][12][13]. The spread of the basic orientation in both types of samples has close magni tudes, i.e., ±3° for α, ±10° for β, and ±7° for γ (Figs.…”

“…Therefore, for an analysis of the crystallo graphic regularities related to the abnormal grain growth, a material can be used with a sharp single component texture of a primary recrystallization (PR), in which it is possible to observe the initial stages of the SR. In particular, it is well known that the rolling of single crystals of Fe-3% Si alloy with the initial cube on edge (Goss) orientation (110) [001] leads to the formation of two symmetrical octahedral orienta tions {111}〈112〉, and a subsequent recrystallization annealing leads to the formation of an Goss texture with a slight scattering of orientations over all angles [3][4][5][6][7]. This means that the realization of abnormal grain growth in the obtained textured matrix with an Goss texture allows one to study regularities inherent in the SR process.…”

Abstract-After the primary recrystallization of a preliminarily deformed (110)[001] single crystal, the tex ture also has the preferred (110)[001] orientation. Furthermore, the texture contains weak orientations, a major part of which is formed at the sample surface and can be described by a spectrum of scattered orienta tions {120}͗210͘…{351}͗103͘. A further heating leads to two concurrent processes taking place in the samples, i.e., the normal growth of Goss grains and secondary recrystallization. Abnormally grown crystals are repre sented by a quartet of orientations related with the initial Goss orientation by a rotation around [011], ,[101], and axes at an angle of ~30°. The crystallographic relationship between the initial and final grain orientations can be explained by their closeness to special misorientations as follows: Σ9, Σ19a, Σ27a, and Σ33a (rotation around ͗110͘ axes to close angles).

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.

This paper deals with a metallographic study of shear and deformation bands, which are formed and developed during rolling and fatigue tests of single crystals and polycrystals of Fe-3% Si. The effect of the initial orientation of the single crystals, dimensions of grains in polycrystals, thickness of the samples and certain rolling factors on the formation of banded structures was analyzed. The effect of these structures on the structure and the texture, which appear in the deformed alloy subject to annealing, was studied too.The obtained data provided a better account of the banded structures and permitted directing ways to control their formation and evolution.
