摘要：

The microstructure and wear resistance of Al-Bi-Ce-Cu alloys were investigated. The intermetallic compounds Bi2Ce form and act as heterogeneous nucleation sites of Bi-rich droplets, which promote the nucleation of Bi phase and obtain a dispersed microstructure. The intermetallic compounds Al2Cu locate in the Al-rich matrix and enhance the hardness of the matrix. The wear resistance of alloys is not only dependent on the size of Bi-rich droplets but also dependent on the hardness of the matrix. The refined microstructure and the strengthened hardness improve the wear resistance of Al-Bi alloys. Therefore, Al-Bi-Ce-Cu immiscible alloys is useful as a wear resistance material.
