The results show that the phase-transition point temperature of CuAlBi alloy is 561.7 ℃, and heat treatment can change the microstructure of CuAlBi alloy. As a result, it can offer the theoretical basis to choose the optimizing microstructure of CuAlBi alloy.展开更多

The results show that the friction coefficient increase then decrease with increase of connecting loading as well as decreases with increase of friction speed, and the wear loss mass increases with increase of connecting loading and friction speed. As a result, the wear failure form of CuAlBi alloy is mainly ploughing.展开更多
