Abstract

Microstructure evolution of SAF2205 duplex stainless steel during torsion deformation was studied at elevated temperatures (600, 800 and 1000 °C). The results indicate that different degrees’ recrystallization phenomena appear and the morphology of austenite is different for the deformed samples. The volume fraction of austenite decreases with the increase of deformation temperature. The fracture morphology of the deformed sample at 800 °C is quite different from that of deformed sample at room temperature. The ductile fracture occurs when the torsion is carried out at the room temperature. Also, the equiaxed and parabolic dimples are observed on fracture surface. However, the fracture morphology of the deformed sample at 800 °C is mainly covered by the intergranular fracture.
