Abstract

Pure Mg single crystals were deformed at room temperature along two orientations in sequence, in order to activate a specific dislocation slip mode followed by \( \left\{ {10\bar{1}2} \right\} \) twinning. The defects in both the matrix and twin crystals were analyzed with a transmission electron microscope (TEM) . This study reveals the collective evolution of the defect substructure when a dislocated crystal is “invaded” by a moving twin boundary . When primarily \( \left[ c \right] \)-containing defects in the matrix were incorporated by a moving twin boundary, including \( \langle c + a\rangle \), pure \( \left[ c \right] \) dislocations and \( I_{1} \) stacking faults, the twin contains homogeneously distributed \( I_{1} \) stacking faults, which in some instances appear to be connected on twin boundary to the faults in the matrix.
