| Abstract | The hot deformation behavior and microstructure evolution of an Fe-30Cr-2Mo ultra-pure super ferritic stainless steel were investigated at the temperature range of 950-1150 degrees C and strain rate varying from 0.01 to 10 s(-1). A strain compensated constitutive equation based on the Arrhenius-type model was established to predict the flow stress. The hot processing map based on the dynamic materials model was achieved to identify the optimum processing parameters. In addition, the features of microstructure evolution combined with the processing map were systematically investigated. The experimental results revealed that the flow stress increased with decreasing deformation temperature or increasing strain rate. Dynamic recovery was confirmed to be the predominant softening mechanism. The values of flow stress predicted by the strain compensated constitutive equation agreed well with the experimental values. The extent of dynamic recrystallization and recrystallized grain size increased with increasing deformation temperature or decreasing strain rate, and the continuous dynamic recrystallization was attributed to be the predominant mechanism of recrystallization during hot deformation. The optimum hot working parameters were determined to be the deformation temperature of 1070-1150 degrees C and strain rate of 0.1-1 s(-1) with a peak power dissipation efficiency of 42%. |
