Thermal Effects in Multicomponent Equiatomic Ni-Based Alloys under High-Energy Irradiation with Kr Ions

Today, the concept of single-phase concentrated solid solutions offers an alternative strategy for increasing radiation resistance materials, namely, a multi-element composition with equiatomic or nearly concentrations. It is highly desirable to understand relationship between chemical complexity alloys and thermal effects associated irradiation in order increase such materials. We present analysis heating, thermoelastic stresses density growth dislocations family Ni-based alloys: NiCo–NiFe–NiCoFe–NiCoCr–NiCoFeCr–NiCoFeMnCr exposed high-energy 145 MeV Kr ions performed by numerical modeling. The results show that alloys, especially NiCoFeMnCr, favors annealing defects, decreases level hazardous relative ultimate strength, reduces dislocation compared Ni.
