Abstract

The occurrence of dynamic recrystallization was investigated under changing deformation conditions, including changes of strain rate and strain path and the effect of annealing. It was found that dynamic recrystallization can be delayed by predeformation at a higher strain rate or facilitated by intermediate annealing, load cycling or strain path changes. The current investigation substantiates that the occurrence of dynamic recrystallization is controlled by the dynamic recovery rate, and that dynamic recovery is much faster and more effective than static recovery in rearranging the microstructure.
