Medium carbon V‐N treated steel grade applied for long products and small drop forged parts investigated in a state of incomplete solution of V(C,N) precipitates. Activation energy changes investigated in the 850–1200°C temperature range and 0.6–30 s−1 strain rate range is revealed to be temperature dependent. Calculated for σp flow stress value this energy in some cases expresses a combination of various processes. It is found that DRX starts well below ∊p. Softening during a short interpass time is caused by dynamic recrystallization DRX during forming and is followed by metadynamic recrystallization MDRX and static recrystallization SRX. At longer interpass times softening progress is hindered by precipitation.
