摘要：
Microstructural evolution of super-clean reduced-activation martensitic steels irradiated with single-beam (Fe+) and sequential-beam (Fe+ plus He+) at 350 degrees C and 550 degrees C was studied. Sequential-beam irradiation induced smaller size and larger number density of precipitates compared to single-beam irradiation at 350 degrees C. The largest size of cavities was observed after sequential-beam irradiation at 550 degrees C. The segregation of Cr and W and depletion of Fe in carbides were observed, and the maximum depletion of Fe and enrichment of Cr occurred under irradiation at 350 degrees C. (C) 2013 Elsevier B.V.
