Abstract

Irregular or smooth grain boundaries after secondary recrystallization are formed depending on whether interpass aging is adopted or not during cold rolling of Fe–3%Si steel. Interpass aging induces the primary texture of high intensity of {111}⟨112⟩ and {411}⟨148⟩ orientations, which have a ∑9 relation with respect to the Goss orientation and therefore are favorable for Goss grains to grow by solid-state wetting. Under this condition Goss grains come in contact with each other by wetting without leaving any small grains in between, resulting in irregular boundaries.
