摘要
Irradiation induced ductility loss of three high-Cr ODS ferritic steels containing oxide dispersoids with different number density and average size was evaluated by utilizing the high-energy Ni ion irradiation at about-50℃.The energy of the incident Ni ions was varied from 12.73 to 357.86 MeV by using an energy degrader at the terminal so that a plateau of atomic displacement damage(-0.8 dpa)was produced from the near surface to a depth of 24μm in the specimens.
