The Co-Cr-Ni ternary system was critically assessed using the CALPHAD technique.The solution phases including the liquid,γ(Co,Ni),εCo and αCr phases were described by a substitutional solution model.The·phase was characterized by a three-sublattice model of (Co,Ni)8Cr4(Co,Cr,Ni)18 in order to reproduce its homogeneity range determined by experiments.A self-consistent set of thermodynamic parameters for each phase was derived.
The Co-Cr-Ni ternary system was critically assessed using the CALPHAD technique. The solution phases including the liquid, γ (Co, Ni), εCo and αCr phases were described by a substitutional solution model. The phase was characterized by a three -sublattice model of (Co, Ni) 8Cr4 (Co, Cr, Ni) 18 in order to reproduce its homogeneity range determined by experiments. A self-consistent set of thermodynamic parameters for each phase was derived.
