Abstract Scope |
Nanocrystalline materials have been proposed as promising candidates for radiation environments due to their high grain boundary density. Indeed, grain boundaries are known as efficient sinks for irradiation-induced defects and studies have presented evidence of enhanced radiation damage tolerance in various systems. However, nanocrystalline materials are not thermodynamically stable and can be prone to irradiation-induced grain growth, reducing the amount of recombination sites and therefore their ability to tolerate damage. A clear understanding of the grain growth during service will accelerate implementation of nanocrystalline materials. In this presentation, we report summary knowledge of nanocrystalline FCC materials, including conflicting data on the applicability of nanocrystalline metals for radiation tolerance. The effect of irradiation and processing conditions on grain growth of FCC metals and the implications in terms of grain size control will be discussed.
