The evolution of the Goss and Cube textures in electrical steel

Abstract

The hot-rolled Fe–3%Si alloy sheets with shear deformation textures were cold-rolled by 80% reduction in thickness and annealed at 800°C. The major components in the hot-rolling textures were {214}〈121〉, {113}〈332〉, {110}〈113〉, and {110}〈001〉. The main components in the 80% cold-rolling textures are {111}〈112〉 and <110>//RD fiber. After the recrystallization, the Goss {110}〈001〉 and Cube {010}〈100〉 textures strongly developed. According to the calculation of the cold-rolling and recrystallization textures, these components originated from the {110}〈001〉 and {110}〈113〉 components in the hot-rolling textures. The evolution of the cold-rolling and recrystallization textures was discussed based on the visco-plastic self-consistent (VPSC) deformation model and strain-energy-release-maximization (SERM) model.
