Recrystallization Texture Evolution in Fe–3.0 wt.% Si Hot-Rolled Silicon Steel Sheet by Quasi In Situ EBSD Analysis

The microstructural and textural evolution in hot-rolled Fe–3. 0 wt. % Si steel sheets was investigated by quasi in situ electron backscatter diffraction (EBSD) analysis. During recrystallization, the Goss texture intensity in the surface region remains essentially unchanged, whereas the α and α* textures are strengthened. In the center region, the α texture weakens, and the α* texture shows little variation, while the Goss texture becomes intensified. In the surface region, 112 recrystallized grains nucleate by consuming deformed matrices with orientations near 114 and 110. Recrystallized 114 and 001 grains consume deformed matrices near 114 and Goss orientations, while Goss grains nucleate by consuming Goss-oriented deformed matrices. In the center region, 112, 114, and 001 recrystallized grains nucleate and grow by consuming α and λ type deformed matrices, whereas Goss recrystallized grains preferentially consume deformed matrices with orientations of 111.
