采用电子束（e-）-氦离子束（He+）同时复合辐照方式，研究低活性Fe-Cr-Mn奥氏体合金时效析出碳化物辐照组织损伤行为，结果表明：时效碳化物边界是空洞优先形成场所，碳化物中出现高密度空洞，同时首次发现碳化物/γ相界面可以发生移动或迁移。论文对这些相不稳定现象从点缺陷与溶质元素相互作用和氦（He）的协同相互效应讨论了时效碳化物辐照损伤的原因，提出了辐照损伤相是相不稳定的一种表现形式。
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.
