The Sn-In-Zn system-application of calphad technique to phase diagram measurement

The phase diagram of one promising lead-free solder system---the In-Sn-Zn system was well constructed by using accurate experimental methods in conjunction with CALPHAD technique. This work is a good example to show that the CALPHAD technique is very useful for phase diagram measurements, especially for those systems with a lot of experimental difficulties. The ternary interaction parameter of the Sn-In-Zn liquid phase was also calculated based on our experimental data and thermodynamic properties from the literatures.
