Dynamic and post-dynamic recrystallization kinetics were investigated during hot-working of Inconel 718 as a function of temperature,strain and strain rate in the single phase domain.The post-dynamic evolution was found to be extremely fast and impacting significantly the grain size.A two-site mean field model including both dynamic and post-dynamic evolution was used to predict the recrystallized fraction, the average grain size and the stress–strain curves in different thermomechanical conditions.
