Abstract Scope |
It has been suggested that CrFeNi-based multi-principal element alloys may exhibit superior mechanical properties and possible increased resistance to irradiation damage compared to traditional alloys. However, expanding the range of irradiation conditions is of prime importance to understand the mechanisms operating in these alloys. Here, the effects of dose and dose rate on the microstructures of Cr0.5FeNiMn and CrFeNiCoPd0.75 during heavy ion irradiation were investigated. Both alloys exhibited phase decomposition. Irradiation accelerated the formation of Ni-Mn rich and Cr rich precipitates in Cr0.5FeNiMn, while CrFeNiCoPd0.75 decomposed into Pd-Fe rich and Co-Ni rich regions. The impact of phase decomposition on the development of loop structure and cavity swelling will be discussed. |
