| Abstract Scope |
In-core structural materials for advanced reactor designs are expected to demonstrate superior resistance to environmental degradation to currently-licensed stainless steels and ferritic-martensitic steels. Compositionally complex alloys (CCAs), which have already shown reduced void swelling compared to less complex binary and ternary alloys, present the opportunity to advance fundamental understanding of matrix composition as a design parameter for irradiation resistance, opening novel alloy design pathways for advanced reactor applications. To compare their swelling behavior to conventional structural materials, two FCC CCA compositions were irradiated to 100 dpa alongside 316H stainless steel at the UW Ion Beam Laboratory using 4MeV Ni ions at multiple temperatures. TEM characterization of irradiated samples is performed to determine the swelling as function of temperature as well as void size and elemental distribution as function of depth. The swelling-temperature bell shape curves are used to assess the void swelling resistance of CCAs relative to more conventional alloys. |
