Effect of Carbon Content on Mean Flow Stress in γ+α Region

摘要：

　　Four carbon content steels were deformed in compression over a temperature range of 600~1000℃ at the same strain rate,and the diagrams of the mean flow stress vs.deformation temperature were drawn up.The mean flow stresses of higher carbon content steels decreased continuously as the applied deformation temperature increased in the whole temperature range,while the mean flow stress of lowest carbon steel displayed an abrupt drop near the γ+α region.The difference in the microstructures was discussed,and the CCT diagrams of two steels were calculated,the reason for the abrupt drop phenomena was explained as the result of phase transformation.
