Keywords:Reduced Activation Ferritic/Martensitic Steel, Irradiation Hardening Behavior, Ion Irradiation

Reduced activation ferritic/martensitic steels (RAFM) are the most promising candidate blanket structural materials for DEMO fusion reactors. The purpose of this study is to summarize the irradiation hardening behavior measured by micro-hardness tests on F82H steels after high-dose ion-irradiation up to 100dpa and compare with the reported data of neutron or ion irradiation.
