Abstract—In present investigation, the study of influence of strain rate and temperature on critical stress for initiation of dynamic re-crystallization in 0.05C-1.52Cu-1.51Mn steel is studied. It was observed that critical stress for initiation of Dynamic re-crystallization (DRX) is increases initially for lower strain rate and then it become saturated at higher strain rate. It is also found that materials exhibits typical dynamic re-crystallization behaviour at higher temperature and lower strain rate. It is due to the influence of thermal energy as DRX is a thermally activated process; also at lower strain rate more time is available for nucleation and growth of strain free crystals.
