摘要：
Compressive deformation of two AI-Li single crystals was investigated as a function of aging condition. Only very weak serrations were detected in the as-quenched condition. Increasingly enhanced serrations with aging were exhibited up to the peak-aged condition. Overaging greatly reduced the serrations. Pair-coupling effect of the moving dislocations due to the shearing of the ordered delta' particles is proposed to be responsible for the observed behavior.
