Abstract:The hot deformation behavior of the 1Cr17Ni1 martensite - ferritic duplex stainless steel at 950-1 150 ℃ with the strain rate of 0.1-10 s-1 on a Gleeble-3800 simulated machine was investigated. The constitutive equation was constructed by using hyperbolic sine function to obtain the apparent deformation activation energy which was 391.586 kJ/mol, and based on dynamic material model the hot processing map of 1Cr17Ni1 steel under different strain was made. At lower deformation temperature, the dynamic recovery and dynamic recrystallization occurred for the tissue morphology. At the high temperature, only the dynamic recovery occured. An optimum processing parameters of hot deformation for this steel can also be obtained by the the processing map and deformation, in which the hot working temperature range was 950-1 000 ℃, and the thermal deformation rate range was 0.1-0.3 and 5-10 s-1.
