Texture Evolution of the Primary Recrystallization and Deformation of Grain-Oriented Electrical Steel With Low Temperature Slab Reheating

The texture from the first cold rolling to the primary recrystallization of low temperature slab reheating grain-oriented electrical steel were researched by orientation distribution function and orientation distribution intensity technique. The results show that after the first stage of cold rolling, there is a strong 001<110> texture in the subsurface and the texture in center layer is very similar to the center layer of hot band which has strong 001<110> and 112<110> texture, due to the heredity. After intermediate annealing the microstructure indicates full recrystallization throughout the sheet thickness. Additionally, the strength of each texture is weakened and the Goss orientation reappears in all layers. There was very little through-thickness variation of the texture after the second stage of cold rolling, exhibiting major 111<112> and minor 001<110> components. After primary recrystallization the texture are qualitatively similar from all layers with the 111<110> is strongest and a certain intensity of Goss texture.
