Abstract
The recrystallisation behaviour of IN 718 has been analysed using a Gleeble 1500 thermomechanical simulator. The use of a rapid water quenching system immediately after the compression test has resulted in the ability to separate dynamic behaviour from meta-dynamic. The rate of dynamic recrystallisation has been found to be proportional to temperature and strain, but inversely proportional to strain rate. The nucleation rate of recrystallised grains during deformation has been found to be directly linked to strain rate and temperature. The rate of meta-dynamic recrystallisation appears to be directly proportional to temperature and strain rate, but no new nucleation events were observed after the end of deformation.
