| 英文摘要 | Sliding and migration of tilt grain boundaries in a Mg-Zn-Y alloy have been investigated on the atomic scale using aberration-corrected scanning transmission electron microscopy. Grain boundary sliding is accommodated by non-basal dislocations moving along the grain boundary; grain boundary migration is induced by the motion of grain boundary dislocations with synchronized grain boundary diffusion. Simultaneous sliding and migration of tilt boundaries take place in both Mg matrix and long period stacking ordered phases. These results provide evidence for occurrence of grain boundary motion, which may play a role in plasticity of this kind of Mg alloys.; Sliding and migration of tilt grain boundaries in a Mg-Zn-Y alloy have been investigated on the atomic scale using aberration-corrected scanning transmission electron microscopy.
