Through Thickness Variation of Cross Shear Rolling Texture in Grain Oriented Silicon Steel

The texture inhomogeneity in cross shear rolled grain oriented Si steel was investigated by means of the through thickness texture analysis. For the chosen rolling reductions (55%, 66.5%) and mismatch speed ratios (1.0, 1.1,1.3), the deformation textures in various thickness layers consist of three major components, i.e. strong γ-fiber,medium α-fiber and weak η-fiber, and they show an asymmetrical distribution throughout the thickness. The effect of reduction on the texture gradient is found to be more significant at and near the center layer; however, the effect subsurface layers, that may favour the formation of a sharp Goss texture during the subsequent annealing.
