Abstract | Ag-21Cu-25Sn alloy ribbon as a promising intermediate temperature alloy solder (400-600°C) was prepared by melt spinning technique in this paper. Rare earth La was added into Ag-21Cu-25Sn alloy to refine the microstructures and improve the wettabilities of as-prepared alloy solders. The phase constitutions, microstructures, melting temperatures and wettabilities of selected specimens were respectively tested. The results showed that the dominant phase constitutions of Ag-21Cu-25Sn-xLa alloy ribbons were Ag3Sn and Cu3Sn. The grain size of Ag-21Cu-25Sn-xLa alloy decreased with the addition of La increasing. La addition reduced the melting temperatures of Ag-21Cu-25Sn-xLa alloy ribbons, and effectively improved the wettabilities of the alloy ribbons. When the addition of La was 0.5wt%, the wettability of as-prepared alloy solder achieved the optimal value of 158cm2g-1 under brazing temperature 600°C and dwell time 15min. In addition, raising brazing temperature and prolonging dwell time could improve the wettability of Ag-21Cu-25Sn-xLa alloy ribbon. |
