The influence of stress-induced-martensitic transformation on the serrated flow behavior associated with dynamic strain aging was investigated. The-martensitic transformation was controlled by changing the deformation temperature and adding Si to Fe-17Mn-xSi-0.3C alloys. The addition of Si promoted the-martensitic transformation, and suppressed the slip deformation due to solution hardening. The initiation of serrations around room temperature was delayed by the promotion of-martensitic transformation which initiated plastic deformation. The critical stress for the occurrence of serrations and the critical stress for the occurrence of slip deformation were found to have a linear relationship.
