Description
Micro-hardness was measured for irradiated F82H steels by single (10.5 MeV Fe3+), dual (10.5 MeV F3+ and 1.05 MeV He+) and triple (10.5 MeV Fe3+, 1.05 MeV He+ and 380 keV H+) beams at the TIARA facility in JAEA. The extra component of radiation hardening due to helium and hydrogen was hardly detected in dual/triple beams irradiation at 543 K and 633 K with comparatively low doses, while that due to helium was slightly occurred in dual beams (10 appmHe/dpa) irradiation at 633 K with higher doses up to 90 dpa. As increased the ratio of He/dpa (from 10 to 100 appmHe/dpa), the extra-hardening due to helium was increased. The microstructures in single/dual (10 appmHe/dpa) ion beam irradiated F82H steels consisted of interstitial loops and defect clusters at 50 dpa. However, at a higher ratio of He/dpa (100 appmHe/dpa), nano-voids were also observed in dual ion irradiated F82H. (author)
