| Abstract Scope |
Searching for better radiation-resistant materials has been a persistent yet scientifically exciting challenge for nuclear applications. Ion irradiation is the most amenable method to reach high doses in a reasonable time and thus often used as a surrogate for neutron irradiation; however, the impact of electronic energy deposition and dissipation by ions is often neglected. Microstructural response of nanostructured materials, including model oxides for nuclear fuels and concentrated solid solution alloys, under ion beam irradiation is reviewed. The role of electronic energy loss on defect production and interface stability is discussed. Understanding the coupling of electronic and atomic processes in the intermediate MeV energy regime, where the energies to displace atoms and induce ionization are both large and comparable, is critically important. Quantified fundamental understanding of radiation damage processes beyond that of simplified displacement events is highly desirable. |
