摘要: 本文用超高压电镜(HVEM)作为电子束源,研究了Fe-15％Cr-30％Ni合金电子辐照后,合金空洞体胀和诱起晶界偏析.实验结果证明:723K,最大剂量15dpa条件下,体胀量为0.62％.在晶界发生Cr贫化、Ni富化.随着辐照温度提高,晶界偏析程度增加,723K时Cr,Ni在晶界出现最大偏析峰,相应空洞体胀量也最大.结果表明,空洞形成和晶界偏析密切相关,本文提出了辐照诱起晶界偏析模型.

Abstract：The void swelling and grain boundary segregation induced by elec-tron irradiation in Fe-15%Cr-30%Ni alloy has been studied, using the high-voltageelectron microscope (HVEM) as the source of electron beam. The results show thatat 723 K and maximum dose of 15 dpa (displacement per atom), the bulk swellingis 0.62%. Ni enriched at the grain boundaries while Cr become depleted. Withincreasing irradiation temperature, the segregation increases. The maximum segrega-tion peak of Ni appears at 723K, accompanied by maximum bulk swelling. A modelof irradiation-induced grain boundary segregation has been proposed to correlatethe segregation with void formation.

Key words： electron irradiation Fe-Cr-Ni alloy void swelling grain boundary segregation
