摘要：

Micro-indentation hardness was measured for the irradiated F82H steels by single (10.5 MeV Fe3+) beam or dual (10.5 MeV Fe3+ and 1.05 MeV He+ ions) beam at the TIARA facility in JAERI. The extra component of radiation hardening due to helium was slightly detected in the dual-beam (10 appmHe/dpa) irradiation at 633 K up to 33 dpa. As increased the ratio of He/dpa (100 appmHe/dpa), the extra component 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. (C) 2004 Elsevier B.V. All rights reserved.
