摘要
Sn-In-Zn三元体系的液相限相图进行了实验和探讨,发现体系存在一个三元低共熔点E:46Sn-52ln-2Zn(100ω),其熔点为108℃.在相图研究的基础上,得出该体系作为无铅焊料的最佳组分为6.7Zn-8.0In-85.3Sn(100ω),其熔化温度为188℃。
The liquidus of Sn-In-Zn system was determmed 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 diagrain 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℃
