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      Received:  18 March 1988      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1988/V24/I3/180 1 Norris I R.
