Evolution of texture in a 2.8%si non-oriented electrical steel annealed at 1100°c

Abstract

The evolution of texture in a 2.8% Si non-oriented electrical steel annealed at 650, 750 and 1100°C was investigated. It was found that, comparing 650°C annealing, Cube and Goss textures in the specimen annealed at 1100°C are strengthened during the early stage of recrystallization. However, the {111}h110i and {111}h112i textures are weakened. Annealing at 1100°C, grains grow rapidly with annealing time in the grain growth stage, Goss and Cube textures are strong and {111}h110i and {111}h112i textures are weak. Cube texture component is strengthened with the growth of grains, Goss texture component is weakened markedly. There is no significant change in the {111}h110i and {111}h112i textures. These characteristics could be attributed to the less recovery before recrystallization and the difference in grain boundary mobility related to the annealing temperature and crystal orientation during grain growth. © 2014 The Japan Institute of Metals and Materials.
