Thus,the apparent activation energy of recrystallization increases with the increase of their Co content in alloys. The relationship botween apparent activation energy and stacking fault energy together with their effect on recovery were also discussed. Key words:  positron annihilation      stacking fault      apparent activation energy      recrystallization      recovery      Received:  18 June 1991      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/Y1991/V27/I6/145 1 Yang Zhi'an, Xiao Yaotian, Shih Changxu.
