Critical strain varies with temperature, strain rate and aging state. The agingconditions and crystal orientations of the loading axes have some effects on the time periodwithin one cycle of serration and stress amplitude of serration. Key words:  serrated flow (PLC) effect      Al-Li alloy      single crystal      Received:  18 June 1997      Service E-mail this article Add to citation manager E-mail Alert RSS Collect articles（0） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1997/V33/I6/577 1Wert J A,Wycliffe P A.Scr Metall Mater,1985;19:463 2 Gregson P J.McDarmaid D S,Hunt E.Mater Sci Technol,1988;4:713 3Tamura M, Mori T,Nakamura T.
