Ten studied steels including different carbon content, silicon content, and manganese content were deformed in compression over a temperature range of 600 C to 1 000 C at the strain rate of 1 s1. The curves of the mean flow stress-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 two phases region. The reason for the abrupt drop phenomena was explained as the result of phase transformation. The mean flow stresses of steels with high silicon content and low manganese content also have this phenomena.  相似文献
