Abstract

A commercial 2507 duplex stainless steel with heterogeneous lamella structures was prepared by cold-rolling and appropriate annealing. A yield strength of 800 MPa, a tensile strength of 1000 MPa and a uniform elongation of 20% were achieved in the sample after 90% cold rolling following by annealing at 900 °C for 1 min. The origin of the excellent mechanical properties was discussed by microstructural features and the evolution of back-stress.
