We investigated the effect of nano-structuring by high-pressure torsion (HPT) on irradiation performance Eurofer-97. Material was deformed to shear strains from 0 ∼230, and then exposed Fe3+ doses 0.01 0.1 displacements-per-atom (dpa). Nanoindentation hardness increases monotonically with deformation, for undeformed material. For both damage levels, less hardening is observed in severely This most prominent strain range ∼60 ∼160, suggesting that may provide an approach reducing hardening.
