Towards mitigating helium damage in nano-crystal iron and tungsten: a strategy based on the dual trap-channel functionality of grain boundaries tuned by their crystallographic character
Nuclear fusion structural materials in critical components like blanket and first-wall are subjected to intense helium (He) generation, causing severe microstructural degradation that limits operational lifetime. Nanocrystalline microstructures have emerged as a promising route toward healing displacement damage. Howev...
