Abstract Phase equilibria between the ferrite phase (α) and the austenite phase (γ) were investigated in the iron-rich corner of the Fe-Cr-Mn-Ni-Si/Al systems at 1000 °C using a diffusion multiple approach and scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS) techniques. Cr equivalents of Si and Al are established as a function of Ni and Mn content in contrast to fixed values reported in other studies. The Cr equivalents of Si (Cr eq Si ) are in the range between −0.5 and 1.3 being positive at 0 wt.% Mn and with values slightly below zero at 5-15 wt.% Mn. The Cr equivalents of Al (Cr eq Al ) ranged between 0.6 and 4.8 decreasing with increase in Ni and Mn content. When compared to Cr eq Al , the Cr eq Si do not show a strong dependence on Ni and Mn content. Thermodynamic calculation using Thermo-Calc software agrees with the experimental results qualitatively.
