Keywords： :serrated flow;frequency;ampitude;single crystal/Al-Li , 频率 , 幅度 , Al-Li单晶体

研究了Al-Li单晶体锯齿流变的动力学特征,结果表明:锯齿的频率和幅度与时效状态、变形温度和加载的晶体学位向相关,并与δ′粒子被切割和固溶Li原子对位错的钉扎有关。

The kinetics of serration in Al-Li single crystalsis studied. The results showthat frequency and ampliitude of serration varies with the aging conditions. The deformation temperatures and the crystal orientations of loading axes. The changs of frequency
