Evolution of recrystallization texture in nonoriented electrical steels Original Research Article

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}<112>, {111}<110> and {112}<110> 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}<112> grains are nucleated within deformed {111}<110> grains and new {111}<110> grains originated in the deformed {111}<112> grains.
