On abnormal growth of {210}<001> grain in grain-oriented silicon steel

The mechanism responsible for secondary recrystallization is still disputed in grain oriented silicon steel. This is mainly related to the complexly of itself. In this work, the occurrence of {2 1 0} texture through secondary recrystallization was observed in the grain oriented silicon steel with Cu 2 S as main inhibitor. In order to elucidate the abnormal growth of {2 1 0} grain, texture evolutions in Fe–3% Si–0.5% Cu steel were investigated using micro-texture analysis. In addition, the {2 1 0} texture was used to validate the current mechanisms of secondary recrystallization. The result indicates that the surface energy plays a significant role in the selection of secondary recrystallization besides the characteristics boundaries which are linked to high mobility.
