Abstract

The fabrication of immiscible alloys with a homogeneous microstructure remains a challenge owing to the liquid–liquid phase separation. The microstructure and mechanical properties of Al–Bi immiscible alloys with the addition of rare-earth Nd are investigated in this work. Scanning electron microscopy analyses show the formation of intermetallic compound NdBi2 during solidification. The rod-like NdBi2 compounds act as heterogeneous nucleation sites for the Bi-rich droplets, which impedes the segregation of the Bi phase and refines the microstructure of the Al–Bi alloys. The results of a wear test show that the addition of Nd in Al–Bi immiscible alloys results in improved wear resistance, which is useful for the development of high-performance self-lubrication materials.
