Calculating Models of Mass Action Concentrations for Ni-Mn and Co-Mn Melts and Optimization of Their Thermodynamic Parameters

According tophase diagrams, measured activities as well as the coexistence theory of metallic meltsstructure involving compound formation, the calculating models of mass actionconcentrations for Ni-Mn and Co-Mn melts are formulated and their thermodynamic parametersare optimized. As a result, the calculated mass action concentrations agree well with thecorresponding measured activities, showing that these models can reflect the structuralcharacteristics of both Ni-Mn and Co-Mn melts.
