Design of radiation tolerant materials for application in extreme radiation environment is a significant scientific challenge. Numerous types of defect sinks, such as grain boundaries and phase boundaries, have been applied to mitigate radiation damage. Twin boundaries have been long considered as ineffective defect sinks. In this presentation, we will review some of our recent studies on radiation tolerance of nanotwinned metals. In situ Kr ion irradiation in a transmission electron microscope, reveal drastic different response of nanotwinned metal to Kr ion irradiation damage compared to their bulk counterparts. Defect migration kinetics (diffusivity of defect clusters) was determined in coarse grained and nanotwinned metals. These studies provide a different perspective towards understanding of twin boundary enabled significant enhancement of radiation tolerance in nanostructured metallic materials.
