Dynamic recrystallization drx
WebApr 5, 2024 · The stress–strain curves show a broad flow stress peak followed by a slight decrease. This shape is typical for the occurrence of dynamic recrystallization (DRX) in conventional BCC metals such as ferritic iron . The rise in flow stress after a steady state is due to the dominance of friction and bulging of the specimens.
