Phase equilibria in the Fe-Mn-Ce system at 900 °C

At 900 °C the liquid phase is stable in the Fe-Mn-Ce system. The isothermal section is characterized by eight three-phase regions: (αFe) + (γFe,Mn) + (βFe17Ce2), (γFe,Mn) + (Fe2Ce) + (βFe17Ce2), (γFe,Mn) + (Fe2Ce) + τ1, (γFe,Mn) + τ1 + τ2, τ1 + τ2 + (Fe2Ce), (γFe,Mn) + (βMn) + τ2, L + (βMn) + τ2 and L + τ2 + (Fe2Ce) plus the corresponding two-phase regions.
