Effects of Post-Rolling Anneal on the Primary Recrystallization Structure and Texture of High Permeability Grain-Oriented Silicon Steel

Abstract:

The decarbonized strips of high permeability grain-oriented silicon steel were annealed at different temperatures in a furnace after rolling at the ratio of 21.1%. The changes of the structure and the texture were analyzed by optic microscope and X-ray diffraction. Results show that the grains are easy to grow up and coarse after annealing, while the texture of the strips changes gradually from {111}<112> to {118}<110> and rotary cubic texture as the annealed temperature rises. The mechanism is that at a relatively lower cold rolling ratio, the distortion storage energy of the ferrite grains in the directions of {118}<110> and {100}<110> is higher than that of the {111}<112> grains so that the texture can form after a suitable annealing process.
