Next generation nuclear reactors require the cladding and structural alloys to withstand higher temperature and higher doses. There are several candidate materials including Al0.3CoCrFeNi, Al0.5CoCrFeNi and Al0.7CoCrFeNi. The samples were prepared by casting followed by 50 hours homogenization at 1,250 ⁰C and further annealing. They represent several different microstructures and phases with single FCC and BCC/B2 phases. Our preliminary study was performed using in situ ion irradiation at 300 ⁰C at the Intermediate Voltage Electron Microscopy Tandem Facility (IVEM) facility using 1 MeV Kr ions to irradiate thin TEM foils of HEA up to 20 dpa, at temperatures from room temperature to 360°C. The results showed good irradiation resistance of the samples with good phase integrity and microstructure stability. Detailed analysis of the ion irradiated samples with different microstructure and composition provides a better understanding of the irradiation performance and clearer guidance for future neutron irradiations experiment.
