Abstract

Unstable plastic flow has been observed in the parabolic stage of work hardening of a zirconium alloy, which was manifested by periodic variations of a spatiotemporal pattern of the local strain distribution. A synergistic model explaining this behavior is proposed according to which the plastic flow evolution in the final stage is considered as an unstable limiting cycle of the dynamical system.
