The development of modern steels depends on the increased understanding of the interactions between alloying elements such as carbon (C) and manganese (Mn) and the α-ferrite/γ-austenite transformation interface. Their analysis is often difficult for the reason that they occur at the nanoscale and in the vicinity of an interface of few atomic plans thick. However, the experimental and theoretical techniques had become much more powerful over the last decade, that is seems fruitful to return to this topic of interest with fresh eyes. In the present work, from a combined selective approach by 3D Atom Probe Tomography, TEM and EBSD, we propose to analyse the behaviour of both C and Mn at the vicinity of the migrating α-ferrite/γ-austenite as a function of its physical nature. Some effects of co-segregation and co-precipitation of both C and Mn at the α/γ interface are evidenced and discussed.
