Kink-band strengthening was first quantitatively evaluated using an Mg–Zn–Y single crystal containing long-period stacking ordered (LPSO) nanoplates. The ability of a kink-band boundary to act as a barrier that hinders the motion of dislocations is high and comparable to that of a general random grain boundary. Nevertheless, a kink-band boundary is regarded as a simple tilt boundary in the dislocation model. One reason for the anomalous ability of kink-band boundary acting as barriers is related to its peculiar hierarchical structure, in which many small kink bands with high crystal rotation angles accumulate in a localized region.

用LPSO纳米片定量估计Mg-Zn-Y单晶中的扭结带强化

首先使用含有长周期堆积有序 (LPSO) 纳米片的 Mg-Zn-Y 单晶对扭结带强化进行定量评估。扭结带边界作为阻碍位错运动的屏障的能力很高，可与一般的随机晶界相媲美。然而，扭结带边界被视为位错模型中的简单倾斜边界。扭结带边界作为屏障的异常能力的一个原因与其特殊的层次结构有关，其中许多具有高晶体旋转角的小扭结带聚集在局部区域。
