Application of Annexation Principle in Investigation of Thermodynamic Property of Ternary Metallic Melt Fe-Cr-Ni

摘要

Based on the phase diagrams,the measured activities and the principle of annexation, a calculation model for mass action concentrations of Fe-Cr-Ni melts, has been formulated. The calculated results not only agree well with measured values, but also obey the law of mass action. It showed that the model can reflect the structural reality of given melts and the principle of annexation is applicable to the ternary metallic melts.
