摘　　要：通过添加微量的Mg、RE和B、RE,熔铸了两组不同Cu-Cr-Zr合金,采用X荧光分析仪、显微电镜、能谱及X射线衍射仪等进行成分分析、组织和性能的比较与研究。结果表明,添加微量的Mg、RE的Cu-Cr-Zr合金综合性能优于添加微量的B、RE的Cu-Cr-Zr合金。The composition, microstructure and properties of Cu-Cr-Zr alloys with trace Mg-RE and with trace B-RE have been compared by X-ray analysis, microscope, EDAX and X-ray diffraction. The experimental results reveal that the comprehensive properties of Cu-Cr-Zr alloy with Mg-RE are superior to that of ones with B-RE.
