摘要：

The interactions of Ce and P on microstructure, mechanical properties in as-cast pure copper were investigated by utilising the OM, SEM and TEM techniques, combined with tensile tests. The results reveal that the micron-scale CeP precipitates are distributed along grain boundaries (GBs), leading to an obvious reduction of grain size and a significant improvement in mechanical properties, compare with pure copper. In addition, the fracture mechanism transformed from microvoid coalescence fracture to quasi-cleavage failure due to the formation of grain boundary precipitates CeP.
