【Abstract】 The effects of sulphur and RE on microstructure and fatigue strength of Cu-Pb al-loy have been investigated in this paper. The results showed that sulphur and RE can refine the microstructure of Cu-Pb alloy, but its fatigue strength decreases with the increase of sulphur, and increases with RE. Further-more, the relation between the mi-crostructure and fatigue strength has also been studied herein.更多还原
