Concentrated solid solution alloys containing multi-principal elements (e.g. high-entropy alloys) have attracted interest because of their outstanding mechanical properties. In order to identify the potential of these materials for nuclear engineering applications, knowledge of irradiation responses is highly desirable. Volume swelling is one of the important irradiation-induced degradation processes for structure materials, but few studies have been performed in the equiatomic alloys. In this study, elemental Ni, binary, ternary, quaternary and quinary Ni-based equiatomic solid solution alloys have been irradiated with 3 MeV Ni ions at 500 ºC up to 60 dpa. Increased swelling is observed with increasing ion fluence. The swelling of the alloys is significantly less than pure Ni. The dependence on number and type of alloying elements will be discussed.
