The critical strain of serration(εc) first increased and then decreased with increasing T or decreasing ε. Temperature and strain rate have some influences on the frequency and amplitude of serration which changed irregularly with deformation. The relations between the type of the serration and the mechanisms for the occurrence of serration, and the changes of frequency and amplitude were obscure in the Al-Li single crystal.
