(a) cavity formation near the GB triple-junction[14](b) cavities near the twin boundary with its corresponding selected area electron diffraction (SAED) pattern[14](c, d) atomistic images showing a dumbbell crossing a CTB during equilibration after radiation cascade[28](e1-e7) in situ snapshots and schematics of distortion and self-healing of CTBs[26](f1-f6) schematics illustrate the capturing of defect clusters by CTBs and their self-healing mechanism(g) the interaction of lattice glide dislocation with a CTB, forming defective CTB[31]
(h) defective CTBs prevailing in deformed nanotwinned Cu structure. Some selected kinks are marked with white arrows. The portion of CTBs marked with an X is perfect TBs without defects[27]
