| Abstract Scope |
Some multicomponent concentrated solid solution alloys, including high-entropy alloys (HEAs), exhibit improved radiation resistance and enhanced structural stability in harsh environments. Energetic ions and electrons are commonly used to create displacement damage for studying the performance of irradiation resistance. Moreover, charged particles, including ions, electrons, and positrons, are unique tools to characterize radiation effects. Applications of charged particles to study irradiation resistance of HEAs are discussed to demonstrate their unique ability to understand radiation damage. In developing structural alloys desirable for applications in advanced reactors, neutron exposure is a critical test but the limitation in achievable high damage levels is a bottleneck. Ion irradiation is often used as a surrogate for neutron irradiation, but cautions need to be taken when relay ion irradiation results for reactor applications. Links to bridge the current advances on fundamental understandings to reactor applications are discussed. |
