Abstract:The hot compression deformation behaviors of high strength carburized SAE9310 steel used for making transmission parts has been investigated by use of Gleeble-3500 simulator at the temperature rang of 1123K to 1423K, strain rate of 0.1-10s-1 and at the true strain of 0.8. The high temperature flow curves of SAE9310 steel have been determined and hot deformed microstructures were observed. The results show that the flow stress and peak strain increase with strain rate increasing or deformation temperature decreasing. At true strain 0.8, the temperature of full dynamic recrystallization increases with the strain rate rising. when the deformation temperature is above 1323K full dynamic recrystallization occurred at strain rate of 0.1-10s-1. The hot deformation activation energy Q of SAE9310 steel is 416.78kJ/mol and the hot deformation equation is derived based on the experiments.
