Thermodynamic Calculation of ternary Phase Diagrams
이동녕 Dong Nyung Lee
Abstract
A rigorous method for obtaining isothermal phase boundaries in ternary systems has been presented when free energy of mixing values are known over the ternary field. The method is equivalent to the common tangent method to obtain phase boundaries in binary systems and is therefore rather conceptual than for the accurate determination of the phase boundaries. For demonstration the method has been used to obtain the ternary phase diagram of the Au-Ni-Cu system whose free energy values were calculated by making use of regular solution equations.
