摘要：

Because of its potential to be used as a lead free solder material the thermodynamic properties of the liquid Al-Sn-Zn system were investigated. Using an appropriate galvanic cell, the partial free energies of Al were determined as a function of concentration and temperature. Thermodynamic properties were obtained for 30 alloys. Their composition was situated on three cross-sections with constant ratios of Sn:Zn 2: 1, 1:1 and 1:2. The integral Gibbs energy and the integral enthalpy for the ternary system at 973 K were calculated by Gibbs-Duhem integration.
