The present study deals with thermomechanical processing behavior of a Nifree high nitrogen bearing duplex stainless steel. This is performed through compressing the material over a wide range of temperature (700-1000 C) under the strain rates of 0.001-0.1 s À1 . The microstructural observations show that continuous and discontinuous dynamic recrystallization are taken place simultaneously in austenite at 900 and 1000 C by generating subgrains and bulging along the prior austenite grain boundaries, respectively. Electron backscattered diffraction analysis also reveals that the occurrence of continuous dynamic recrystallization is the governing restoration phenomenon in ferrite over the studied conditions. At last, to consolidate the experimental results, a strain-compensated constitutive model is developed to predict the flow behavior of N-bearing duplex steel.
