| Abstract Scope |
Compositionally Complex Alloys (CCAs) are multi-component alloys which have been reported to exhibit desirable mechanical and radiation-tolerant properties. While several CCAs have shown excellent phase stability and resistance to void swelling under irradiation, the origins of these properties are still under debate – further challenging CCA development. Indeed, while CCAs intrinsic radiation resistance properties have been hypothesized, few of them have been confronted to experimental validation. In addition, it is still unclear if these properties can be generalized across the extensive CCA composition fields. In light of this, FCC and BCC CCA fundamental radiation damage properties were investigated under cryo and high-temperature in-situ ion irradiation. Void swelling behavior was also studied under in-situ dual He beam implantation. To investigate if these properties can be generalized across the CCA composition field, high-throughput (i) synthesis, (ii) ion irradiation, (iii) characterization techniques have also been employed to accelerate CCA development for nuclear applications. |
