Microstructure, phase composition, melting characteristic, wettability and hardness of the alloys were investigated, and the influence of the rare earth Y on the formation of intermetallic compound among Sn-58Bi/Cu were analyzed, and the shear strength were test. The results show that the Sn-Bi microstructure is refined, and the microstructure of Sn-58Bi-<i>x</i>Y is rich in Sn phase, Bi phase and eutectic microstructure of layered structure. The rare earth Y is distributed in rich Bi phase evenly. The melting points and melting ranges are less affected with the Y addition. The wettability of Sn-58Bi alloys reduces when the Y contents increase, but the hardness of Sn-58Bi alloys increases and reaches the maximum value 24.18HV when the content of Y is 0.4<private-char description="%">%</private-char>. Rare earth Y can improve the shear strength of Sn-58Bi-<i>x</i>Y/Cu solder joints, and the shear strength of the joints reach the maximum value 53.55 MPa when the content of Y is 0.2<private-char description="%">%</private-char>. Y can promote the reaction of Sn-58Bi solder with Cu during welding and forming Cu<sub>6</sub>Sn<sub>5</sub> intermetallic compound. |
