Abstract：

For alloy steel S34MnV used in the manufacture of large marine crankshaft, the hot compression experiment was carried out by the Gleeble-3800 thermal simulation test machine. Then, deformation behaviors of alloy steel S34MnV were researched at 950～1250 ℃, strain rate of 0.001～10 s-1 and compression deformation of 70% , and the true stresstrue strain curves were gained. In addition, the influences of deformation temperature and strain rate on rheological behavior of alloy steel S34MnV were analyzed. The results show that deformation temperature and strain rate have significant influences on the flow stress. The flow stress decreases with the rising of deformation temperature and increases with the increasing of strain rate. When the strain rate is lower and deformation temperature becomes higher, the dynamic recrystallization occurs easily and is helpful to reduce the flow stress.
