Abstract Scope |
The kink band formation process in Mg-6%Zn-9%Y alloy with the long-period stacking ordered (LPSO) phase was investigated in detail by in-situ compressive test and observation by SEM, and it succeeded in capturing the microstructural change with no surface relief which should be called as the pre-kink band. Using the SEM and the TEM analysis, it clearly founded that the pre-kink band involves the mobile and angle-variable terminated-subgrain-boundaries which consists of edge dislocation arrays. We are now developing the formation model of the pre-kink and kink band based on the disclination motion. |
