Abstract Scope |
Magnesium alloys with long-period stacking ordered phase are well known to have superior work hardening rate comparing with conventional magnesium alloys. Plastic deformation of long-period stacking ordered phase occurs though kink deformation with suppressing formation of twins. It is generally believed that kink-interfaces act as obstacles against slip deformation resulting in high work hardening rate. Therefore, it is important to control the fraction of kink-interfaces in the alloy during production process to achieve excellent mechanical properties. In this study, we have employed high-pressure torsion process which can switch a direction of shear strain during deformation, and the effect of deformation path on the formation of kink-interfaces has been investigated. |
