摘要：
Mo particle reinforced copper composites with 2.5vol%similar to 10.8vol% Mo were prepared by electron beam physical vapor deposition (EB-PVD). The microstructure, hardness and electrical resistivity were investigated. The results show that the Cu matrix is composed of columnar microcrystalline and the average grain size of Mo is 2.4 similar to 8.1 nm; the columnar crystal width of copper matrix decreases, while hardness and electrical resistivity of the composites increase with the increase of the Mo content. The strengthening mechanism of the composites by EB-PVD is mainly the Orowan mechanism.
