Abstract
This paper addresses adiabatic shear localization from a different point of view. New results are reviewed which indicate that the process can be viewed as triggered by dynamic recrystallization instead of being the result of thermal softening as universally assumed. A simple dislocation dynamics model (modified ETMB) is used to reproduce the salient features of the physical observations, namely dynamic recrystallization in the strain-hardening phase with a minor temperature rise. The main parameters of the model are discussed from an experimental identification point of view.
