In this study, the effect of thermo-mechanical treatment on superplasticity of 24Cr-7Ni-3Mo-0.14N alloy was investigated at 850 C in three phase regime consisting of {alpha}, {gamma} and {sigma} phases. In order to examine the effect of thermo-mechanical treatment conditions on superplasticity, the solution treatment temperature and cold reduction ratio were varied. The effects of thermo-mechanical treatment conditions on the microstructural factors of constituent phases were analyzed. The relationships between the microstructural factors and superplasticity in Fe-24Cr-7Ni-3Mo-0.14N duplex stainless steel were discussed.
