The effects of temperature on the bulk and surface properties of liquid Zn-Cd alloys have been theoretically investigated, using a combination of self association model, Darken's thermodynamic equation for diffusion, empirical model for viscosity and a statistical mechanics model. The results from this study show that change in temperature resulted in cross-over effects in bulk and surface properties. We also found that with an increase in temperature, a pronounced asymmetry of viscosity isotherm is significantly reduced, and viscosity isotherm exhibited anomalous behaviour. Our results reveal that the homocoordination tendency in Zn-Cd liquid alloys is not strong and reduces with increasing temperature. The study further suggests a pronounced segregation of Cd-atoms at the surface of Zn-Cd liquid alloys and the extent of segregation reduces with temperature. We as well found that, in addition to the reported understanding that size-factor determines the compositional location of asymmetry of the viscosity isotherm, temperature is an operating parameter that has effect, not only on the composition of asymmetry, but also on the magnitude of asymmetry. In all the properties investigated, the most pronounced effect of temperature (52.9%) is on the viscosity while the least effect (7.1%) is on the surface tension.

“…(7). Also, in line with the usual practice [32,36] the same values of the fitting parameters employed in the computation of bulk properties are used in the computation of surface properties. The values of m and W employed in our calculations following the procedure explained in the preceding paragraph are shown in Table 1.…”

“…The investigation of the ternary Al-Sn-Zn system yields a consistent set of thermodynamic data of the liquid alloys, which may be useful for the development of new leadfree solder materials and also for the calculation of the ternary phase diagram and to determine the surface tension and the wettability with different models as it was done by Prasad et al [46][47][48] …”

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.

“…For this purpose, several authors have proposed calculation methods of surface tension of liquid [1][2][3][4][5][6][7][8][9][10][11]. In our previous work [11], we have presented calculation method using Butler's equation [12] for the systems having a thermodynamic behaviour characterised by short-range order explained by the presence of associated atomic groups (cluster) in liquid.…”
