A contribution to the Al-Pb-Zn ternary system

The liquidus curve projection of the Al-Pb-Zn ternary system is the only experimental result for the Al-Pb-Zn ternary system in the existing literature. Due to the lack of other experimental data, thermodynamic calculations based on the extrapolation of its binary systems are performed in the present paper. The ternary interaction parameters used in this work are obtained by Chou's general solution model, which, in the absence of experimental data, offers a reasonable guide for the phase diagram calculation. As a result, a set of isothermal sections, isopleth sections and liquidus curve projections of the Al-Pb-Zn system, especially the liquidus curve projection of the Pb-rich corner, have been obtained.
