316 stainless steel model alloys with different Si and Ni content are irradiated by 3MeV Ni2+ at 288°C, to achieve ~1.2dpa at peak damage. Irradiation-induced hardening is observed by nano-indentation. Microstructure change of irradiated samples will be characterized and compared with hardness results, and composition effects will be analyzed.
