The effect of high-pressure torsion on irradiation hardening of Eurofer-97 [PDF]
Nuclear Materials and Energy, 2023 We investigate the effect of nano-structuring by high-pressure torsion (HPT) on the irradiation performance of Eurofer-97. Material was deformed to shear strains from 0 to ∼230, and then exposed to Fe3+ irradiation doses of 0.01 and 0.1 displacements-per-
