Secondary recrystallization in Fe-3% Si alloy with (110)[001] single-component texture

Abstract

After the primary recrystallization of a preliminarily deformed (110)[001] single crystal, the texture 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 orientations 120вЊ©210вЊ.351 вЊ©103вЊ. 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 represented by a quartet of orientations related with the initial Goss orientation by a rotation around [011], [011̄], [101], and [101̄] 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 〈110⌠axes to close angles). © 2013 Pleiades Publishing, Ltd.
