Nanostructured bainitic steel consisting of nanoscale bainitic-ferrite and retained austenite has been obtained by transforming at 200°C for 10 days. Despite the large volume fraction of retained austenite (29 vol.%) obtained, the total elongation of the nanostructured bainitic steel was relatively low. Microstructural characterization indicates that the high tensile strength (1975 MPa) resulted from nanoscale bainitic ferrite laths (~50 nm) with high dislocation density (7.4·1015 m–2) in the microstructure. The total elongation (5.8%) is attributed to the formation of Fe–C clusters and carbides in the microstructure and to the twinning (~20 nm in thickness) of retained austenite flakes.
