It is well known that alloying elements significantly affects the phase transformation process in steels. Understanding the segregation and partitioning of the substitutional and interstitials elements at the moving transformation interface is a key to control microstructure formation and those the properties of the steels. In this paper, the atomic scale redistribution of the alloying elements across the austenite-ferrite interface in a model Fe-C-Mn steel is investigated. Different interfaces developing under various thermodynamic conditions were selectively analyzed using EBSD, FIB, TKD and APT experimental techniques. The profiles of both C and Mn are discussed with respect to the existing interfacial models for phase transformation in steels.
