Substitution of gold in part for silver in Ag3Sn alloys is found to result in two separate phases: gamma (Ag3Sn particles) grains with a uniform distribution of gold within the grain and an Au-Sn phase in a form of ring surrounding the gamma grain. The thickness of this ring increases with increasing gold concentration. The phases were identified by using the techniques of x-ray diffraction, optical metallography, scanning electron microscopy, and x-ray energy dispersive spectroscopy.
研究发现，在Ag3Sn合金中用部分金替代银会产生两个不同的相：γ（Ag3Sn颗粒）晶粒，其中金在晶粒内均匀分布；以及呈环绕γ晶粒的环状形式的Au-Sn相。该环的厚度随着金浓度的增加而增加。通过使用X射线衍射、光学金相显微镜、扫描电子显微镜和X射线能量色散光谱技术对这些相进行了鉴定。
