Excellent combination of strength and ductility in 15Cr-2Ni duplex stainless steel based on ultrafine-grained austenite phase

The room-temperature duplex structure of duplex stainless steel is always metastable, which suggests that non-equilibrium phase transformation can be further exploited for producing duplex stainless steel having the same chemical compositions and phase constitution but different microstructures. Thi...
