Prediction of thermodynamic properties associated with six component alloys, Pb-free quaternary and ternary alloys

In this study, Chou’s general solution model (GSM) and the geometric models were applied to six
components liquid and quaternary, ternary liquid alloys for high temperature. In all geometric models, the
enthalpy and partial enthalpies of mixing of liquid Ni-Cr-Co-Al-Ti-Cu of six components for the cross
sections, xNi/xCr =1, xNi/xCo =1, xCr/xCo =1, r=xAl / xTi , Pb-free quaternary Au–In–Sn–Zn alloy for the
cross section, xIn / xSn = 2, xSn / xZn = 1 and ternary In-Pd-Sn alloy for the cross section, xIn/xSn =1 have
been evaluated at the temperatures 2000 K, 773 K and 1173 K, respectively, in order to compare with the
experimental results. Generally speaking, it is seen that there is an agreement between the results of
geometric models and those of thre experimental results.
