    Atomic-scale grain rotation processes in NC AuCu alloy are captured in situ. We discovered a full dislocation-mediated reversible grain rotation that has rarely been reported before. The results show that, with loading, full dislocations nucleate, glide across the grain to the grain boundary (GB) an...
