摘　　要：用SPS热压烧结技术制备原位自生的Al2O3-TiC增强铜基复合材料。利用光学显微镜（OM）,X射线衍射仪（XRD）,扫描电镜（SEM）分析（Al-TiO2-C）含量、烧结温度对复合材料组织和性能的影响。结果表明：随着（Al-TiO2-C）添加量的增加,复合材料的晶粒尺寸逐渐减小,电导率下降明显,硬度增加明显;而随着烧结温度的提高,复合材料的晶粒尺寸逐渐减小,电导率升高,强度先增加后减小;当（Al-TiO2-C）的含量为8%,烧结温度为980℃时,复合材料的组织与性能最优。The in-situ Al2O3-TiC reinforced copper matrix composites were prepared by SPS method. The effect of（Al-TiO2-C） content and sintering temperature on microstructure and properties of the composites were analyzed by means of optical microscope,X-ray diffractometer and scanning electron microscopy（SEM）. The results show that with the increasing of（Al-TiO2-C） content,the grain size and the conductivity of the composites decrease,the hardness increases obviously. With the increasing of sintering temperature,the grain size of the composites decreases gradually,the conductivity increases,the strength increases first then decreases. When the content of（Al-TiO2-C） is 8% and the sintering temperature is 980 ℃,the microstructure and properties of the composites are optimal.
