Severe high energy particle (neutron) and ion irradiation environment can introduce significant microstructural damage and consequent degradation of mechanical properties in irradiated metallic materials. It remains a scientific challenge to design advanced radiation tolerant materials. Numerous approaches have been applied to alleviate radiation damage. Here we will present some recent studies on enhanced radiation tolerance of nanostructured metallic materials, in particular nanoporous metals. In situ heavy ion irradiation studies reveal direct evidence of defect-free surface interactions in nanoporous metals. Defect migration kinetics (diffusivity of defect clusters) was compared between coarse-grained and nanoporous metals. These studies provide insight towards understanding on the role of free surface on alleviation of radiation damage in metallic materials.
