摘要	Two types of austenitic stainless steel samples were prepared by means of dynamic plastic deformation followed by annealing: nanotwinned austenitic grains embedded in recrystallized austenite matrix and martensitic/austenitic duplex microstructures. Annealing at 923 K induced martensitic reversion while most nanotwinned grains are stable. An enhanced strength-ductility combination is observed in the annealed nanotwinned samples which exhibit a uniform elongation of similar to 21% and a yield strength of similar to 900 MPa, in contrast to a uniform elongation of similar to 12% with comparable strength in the martensitit/ austenitic samples.
