Abstract Scope |
Nanocrystalline materials were postulated as irradiation resistant materials due to the high density of grain boundaries (defect sinks). These materials can be synthesized via severe plastic deformation methods, material deposition or through mechanical alloying. Here we give an overview and new insights on the performance of different nanocrystalline BCC materials (W, Fe, HT-9 alloy, W- alloys, and W-based high entropy alloys) exposed to extreme irradiation and implantation conditions. We demonstrate the performance of these materials as a function of grain size and we compare some of them to their coarse grained counterparts. The dependence of the performance of nanocrystalline materials on the irradiation conditions is elucidated. Finally, assessment of mechanical properties of irradiated nanocrystalline materials and limitations of some characterization methodologies are presented.
