Abstract
The steady-state behavior of dynamic recrystallization (DRX) was studied in commercially pure copper and the austenitic steel alloy 800H. Investigations on the flow stress behavior during strain-rate and temperature-change tests in the steady-state regime regarding the grain size sensitivity of the flow stress were analyzed. The results confirmed the predicted connection of DRX grain size and deformation-induced subgrain size. Furthermore, the grain size distribution during steady-state DRX was evaluated and found to remain constant. A continuity equation of the growing and shrinking grain distributions is proposed which allows the steady-state flow stress to be calculated.
