Abstract In this study ,irradiation damage characteristic of carbide in Long term aging treatment for Fe-Cr-Mn alloy is investigated by electron beam and dual-beam with electron–hilum ion irradiation. The results indicate that the voids were observed inside carbide and along interface of carbide/matrix. Interface migration and interface segregation of Cr. Mn. W. V is first observed. The phase stability and reason of the irradiation damage of aged carbide are discussed with the interaction between point defects and solute elements and radiation-induced synergistic effect of hilum. The radiation damage phase is a form of expression of the unstability of phase.
