Abstract

In the present study, it is found that one-pass friction stir processed AZ61 alloy exhibits inferior deformation ability along the longitudinal direction compared with the transverse direction at high temperatures. Based on observation of microstructure and fracture surface, premature onion ring splitting is suggested to be mainly responsible for this anisotropy of deformation behavior. Furthermore, the homogeneous microstructure from multi-pass friction stir processing can cure the premature onion ring splitting and then exhibit isotropic high-temperature superplastic deformation behavior.

Keywords:: Magnesium alloys; Friction stir welding; Superplasticity; Onion splitting
