| Abstract Scope |
Single-phase concentrated solid solution alloys (CSAs) have drawn increasing interest due to their outstanding properties, including exceptional fracture toughness at cryogenic temperatures, high strength and low plasticity at elevated temperatures, and enhanced radiation tolerance. Using computational and experimental approaches, the effects of electronic energy deposition and dissipation from energetic ions on damage production and evolution have been investigated. Electronic energy loss affects damage production in single and overlapping collision cascades (30 to 150 keV). Experimentally, the tunable chemical complexity, local lattice distortions, and nanostructured features of CSAs are exploited to control energy dissipation, defect dynamics and microstructure evolution. These results suggest a new paradigm for designing enhanced radiation tolerance. This work was supported by EDDE, an EFRC funded by the U.S. DOE, BES. |
