Abstract

Effect of hot rolling and effect of hot rolled-normalizing on microstructures and textures of silicon steel sheets were investigated. In hot rolled steel sheets, fine elongated grains and etch pits were observed. \( \left( {001} \right)[1\bar{1}0] \), \( \left( {112} \right)[1\bar{1}0] \) and \( \left( {223} \right)[1\bar{1}0] \) were strong orientations at the core of steel sheet. At surface and subsurface, \( \left( {110} \right)[001] \) and \( \left( {110} \right)[1\bar{1}2] \) orientations were dominant orientations. In hot rolled-normalized steel sheets, coarse elongated grains and randomly distributed etch pits were observed. Volume fraction (%) of \( \left( {001} \right)[1\bar{1}0] \) orientation was found to be decreasing from core to surface, similar trend was found for \( \left( {112} \right)[1\bar{1}0] \) and \( \left( {223} \right)[1\bar{1}0] \) orientations. \( \left( {110} \right)[1\bar{1}2] \) & \( \left( {110} \right)[001] \) orientations are the dominant orientations at the surface. Volume fraction (%) of \( \left( {110} \right)[1\bar{1}2] \) is more than Goss at the surface.
