Recrystallization textures and microstructures of Al-0.3%Cu alloy after deformation to high strains

Abstract

An Al-0.3%Cu alloy was deformed to high strains by cold rolling. The as-deformed samples were annealed at different temperatures until complete recrystallization. The cold rolling textures were determined by X-ray diffraction while the recrystallization textures and microstructures were characterized by electron backscatter diffraction. It was found that the rolling texture was characterized by a strong Brass component. After complete recrystallization Goss and Cube textures were developed. The effects of deformation strain and annealing temperature on the recrystallization textures are discussed.
