Process parameter influence on deformation and recrystallization textures in Al alloys

Abstract

Abstract Mesoscopic changes take place during the entire thermomechanical processing (TMP) of polycrystalline metallic materials. Controlling the TMP parameters is of key importance since both microstructure and texture evolution of a particular technological step severely influence the final properties of a given product. This study is focusing on the crystallographic aspect of microstructural formation in Al alloys. The effect of straining level on the crystallographic texture evolution and texture-dependent properties is discussed. This contribution clearly demonstrates that the plastic stain ratio can be modified via TMP route. Implementation of relatively small deformation could account for improvement of anisotropy of plastic yielding, necessary for advanced deep drawing qualities.
