英文摘要 | The deformation microstructure of an interdendritie 18 R long-period stacking ordered (LPSO) phase in an Mg-Zn-Y. alloy subjected to shock loading was investigated by transmission electron microscopy. It was found that kink banding, the key deformation mode of LPSO phases under quasi-static loading, is suppressed by shock loading. Instead, second-order pyramidal slip by < c + a > dislocations, which has not been observed in LPSO before, contributes to the plastic deformation of LPSO, in addition to the < a > dislocations. The rate-dependent deformation modes of LPSO have an important implication in understanding the mechanical behaviour of LPSO strengthened Mg alloys under extreme loading conditions. |
