| 摘 要： | 采用非真空熔铸方法制备的Cu-Cr-Zr合金,通过显微硬度、导电率测试以及扫描电子显微镜和能谱仪等试验方法和设备观察分析了材料的组织和性能。结果表明:非真空熔铸的Cu-1.02Cr-0.34Zr和Cu-0.90Cr-0.18Zr合金主要由Cu、Cu5Zr、和Cr组成。其铸态显微硬度和导电率分别达到HV102、HV100和51%IACS、53%IACS。经过800℃×50 h的热处理后,合金显微组织更加细小均匀。

| Abstract: | The Cu-Cr-Zr alloy was melted and cast in non-vacuum condition.The microhardness and electrical conductivity were tested.The microstructure of the alloy was observed by scanning electron microscope,and the matrix was analyzed by energy disperse spectroscopy equipped on SEM.The results indicate that the casting Cu-1.02Cr-0.34Zr and Cu-0.90Cr-0.18Zr alloys melted in non-vacuum are consisted of Cu,Cu5Zr and Cr.The as-cast microhardnesses of the Cu-Cr-Zr alloy are HV102 and HV100,and the electrical conductiviti... |
