Influence of grain boundaries on the radiation-induced defects and hydrogen in nanostructured and coarse-grained tungsten

We have studied the influence of grain boundaries (GBs) on the radiation-induced defect evolution and on H retention at 300 K, both experimentally and by computer simulations. For this purpose, coarse-grained tungsten (CGW) and nanostructured tungsten (NW) samples were implanted with H and C ions at...
