Nanotwinned (NT) Cu have shown outstanding radiation tolerance compared with its coarse-grained counterpart, as twin boundaries (TBs) can effectively engage, transport and eliminate irradiation-induced defects. The radiation tolerance of NT Cu can be further enhanced by introducing nanovoids (NVs), which act as storage bins for defects. Using in situ radiation technique inside a transmission electron microscope, we investigated in NT-NV Cu how defects evolve and distribute during early stage (low-dose) irradiation. Defects-TBs interactions are also discussed. In situ studies show that TBs and NVs can influence defects formation and distribution. In parallel defects can cause TB migration and shrinkage of NVs.
