Abstract

Electropulsing-induced evolution of texture during recrystallization of Fe–3%Si alloy strip was studied using electron backscattered diffraction and x-ray diffraction techniques. Under electropulsing, various textures occurred during several seconds of recrystallization in the alloy. The Goss texture (G-texture) with high energy storage developed with increasing misorientation distribution of the low-angle grain boundaries. The mechanism of the electropulsing-induced G-texture evolution was discussed from the point of view of electropulsing dynamics.
