Abstract Scope |
In-core structural materials for sodium fast reactors are expected to demonstrate radiation tolerance up to several hundreds of displacements per atom (dpa) over the operating lifetime. Compositionally complex alloys (CCAs) consisting of four or more principle alloying elements in single-phase solid solution are theorized to resist radiation due to unique energy and mass transport properties. Due to the vast range of the CCA compositional space, rapid screening of compositions for nuclear reactors must adopt high-throughput experimental techniques to generate libraries of data to link trends in resistance to irradiation with composition. 4” diameter thin films, compositionally graded in CrFeMnNi, have been fabricated by magnetron co-sputtering and irradiated to 5 dpa using an automated stage. Libraries were characterized before and after irradiation using XRD, nano-indentation, four-point probe, profilometry, and for select compositions, TEM. These high-throughput results are discussed alongside the limitations of using thin films in irradiation experiments. |
