Molar Volume Calculation of Molten Ag–Au–Cu and Cu–Ag–In Alloy Systems Using General Solution Model

Abstract—However, up to the present, there was few reports on the density of the molten Ag–Au–Cu and
Cu–Ag–In alloy systems. In this work, using the determined densities for these alloys in literature, the molar
volumes of these alloys have been calculated according to the Chou’s general solution model (GSM), using
known experimental data for constitutive binary systems at a temperature of 1381 K, 973 K and 1173 K, for
the considered ternary alloys mentioned above in the sections with molar ratios of xAu/xAg = 0.4 and 2.5,
xAg/xIn = 0.5, 1 and 2, respectively. In addition, the calculated values for the molar volume of liquid alloys
in question have been compared with available experimental data.
