摘要

This study investigated the microstructure and vibration properties of Sn-Zn and Sn-Zn-Bi alloys with different Zn contents. Experimental results show that the hypoeutectic Sn-Zn-Bi alloy (with a Zn content of 5 wt.%) has the poorest damping capacity and the lowest critical vibration cycles to failure due to a hardening effect by Bi and intergranular fracturing. On the other hand, since the Zn/Sn interfaces at which internal friction may occur during vibration contribute to the dissipation of vibration energy, the hypereutectic Sn-13Zn samples with numerous massive primary Zn needles possess superior damping capacity and vibration life under constant vibration force conditions.
