Abstract Scope |
Recently, double-soaking of Medium-manganese (Mn) steels has been proposed to produce multiphase microstructures consisting of martensite and austenite, alternative to ferrite-austenite microstructures produced via single-soak intercritical annealing. By substituting ferrite with martensite, double-soaked medium-Mn steels exhibit increased strength, in excess of 1600 MPa, in combination with appreciable ductility, in excess of 13 pct total elongation. The present work contains modelling efforts for phase evolution and solute redistribution during double-soaking, conducted via DICTRATM and MICRESS®, that corroborate energy dispersive X ray spectrometry (EDS) conducted in a scanning transmission electron microscope (STEM). The modelling elucidates how Mn and carbon (C) redistribution enable the formation of the martensite-austenite microstructure. |
