英文摘要	The irradiation resistance of CLF-1 steel was investigated by using He ion irradiation with an energy of 300 keV. After the irradiation, the structure of CLF-1 steel mainly remained martensitic structure, while the lattice distortion and grain refinement occurred in the irradiation damaged layer. As irradiation fluence increased, the number of vacancies in CLF-1 steel increased, and the vacancies combined with the He atoms to form a bubble layer with the thickness of about 300 nm which located at the end of the He ions range. In the bubble layer, local amorphous region formed and the carbide particles showed a tendency to decompose. When the irradiation fluence was up to 1 x 10(18) ions/cm(2) , extensive blisters and a small amount of peelings appeared on the surface of CLF-1 steel. Due to grain refinement and dispersion of small carbide particles, the hardness of CLF-1 steel increased after the irradiation. (C) 2018 Elsevier B.V. All rights reserved.
