Evolution of recrystallization texture in nonoriented electrical steels

Abstract The mechanism responsible for the formation of recrystallization texture is still disputed although recrystallization texture has long been a subject of research. This is mainly related to the complexity of recrystallization itself. The mechanism of recrystallization texture in a 2% Si steel was investigated. In addition, the origin of nuclei with specific orientations was studied. The formation of recrystallization texture is explained by oriented nucleation. Most nuclei have a high misorientation angle of 25∼55° with the surrounding deformed matrices. New Goss grains are mainly nucleated within shear bands in the deformed {111} , {111} and {112} grains, and the number of shear band decreases in the same order. The nucleation of new Cube grains also takes place within shear bands. New {111} grains are nucleated within deformed {111} grains and new {111} grains originated in the deformed {111} grains.
