| Abstract: | The liquidus of Sn-In-Zn system was determined by means of DTA technique. It was proved that the system has a ternary eutectic point at 108℃ containing Sn:46, In:52, Zn:2(100w). Based on the phase diagram and the DTA results. the optimum component of Sn-In-Zn alloy used for lead-free solder is recommended as(6.7Zn--8.0In-85.3Sn) with a melting temperature of 188℃. |
