Microstructures and Textures of Hot Rolled and Hot Rolled-Normalized 2.9 % Silicon Steel Sheets

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. , and were strong orientations at the core of steel sheet. At surface and subsurface, and orientations were dominant orientations. In hot rolled-normalized steel sheets, coarse elongated grains and randomly distributed etch pits were observed. Volume fraction (%) of orientation was found to be decreasing from core to surface, similar trend was found for and orientations. & orientations are the dominant orientations at the surface. Volume fraction (%) of is more than Goss at the surface
