摘要: Abstract In order to explore the chemical effects on radiation response of alloys with multi-principal elements, defect evolution under Au ion irradiation was investigated in elemental Ni, equiatomic NiCo and NiFe alloys. Single crystals were successfully grown an optical floating zone furnace their (100) surfaces irradiated 3 MeV ions at fluences ranging from 1 × 1013 5 × 1015 ions cm−2 room temperature. The irradiation-induced analyzed by using channeling technique. Experiment shows that is more irradiation-resistant than pure Ni low fluences. With continuously increasing fluences, damage level eventually saturated for all materials but different dose levels. saturation appears relatively lower fluence alloys, suggesting accumulation slows down Under high-fluence irradiations, has wider ranges indicating defects have high mobility.
