Popis:	Ferrite and austenite duplex stainless steel with heterogeneous lamella structure was fabricated by severe cold-rolling and short-time annealing. The processed steel exhibited superior cryogenic mechanical properties with a tensile strength of ∼1650 MPa and an ultimate tensile strain of ∼30%. The excellent combination of cryogenic strength and ductility was attributed to fine grain size, nanotwins, back-stress hardening, and deformation-induced martensitic transformation.
