PHASECALC: A code for the calculation of pseudobinary phase diagrams using no adjustable parameters Original Research Article

Pseudobinary phase diagrams are often used in the analysis of ternary semiconductor compounds of the form B1−xAxC where A, B and C are the pure elements and 0⩽x⩽1. The code PHASECALC is used for the calculation of pseudobinary phase diagrams. The code utilizes the Stringfellow method, and a modification of this method, to perform this calculation using no adjustable parameters. PHASECALC computes the temperature dependent solidus and liquidus lines as a function of mole fraction x. PHASECALC requires the following input data: enthalpy of fusion, melting temperature, and lattice constant for the pure binary compounds (AB and BC), electronegativity, molecular weight, density and energy of vaporization for the pure elements A and B.
