Crystallographic Dependence on Deformation Characteristics of Friction Stir Processed Pure Aluminum

Abstract

Anisotropic deformation behaviors of the friction stir processed dynamic recrystallized commercial pure aluminum alloys were studied in this study. Recrystallized and refined grain size can be acquired after friction stir process is conducted. However, this is not guaranteed of isotropic deformation characteristics. Microhardness profile within the friction stir processed region is crystallographic orientation dependence. This dependence is manifested properly by the corresponding average Taylor factors.
