Dynamic recrystallization behavior and hot deformation characteristics in 4340 steel

4340 steel is extensively utilized in the automotive industries and for a large number of general purposes. Due to the importance of thermo-mechanical processing in the production of steels, the dynamic recrystallization (DRX) characteristics of 4340 steel were investigated in the present study. Namely, hot compression tests on 4340 steel have been performed at a temperature range of 900–1200°C, a strain rate range of 0.01–1 sec–1, and a strain...
