摘　　要：综述了高强度、高导电氧化铝弥散铜基复合材料的各种制备方法,尤其是对内氧化法进行了述评;从内氧化热力学的角度初步介绍了内氧化介质和内氧化工艺参数对制品组织结构和性能的影响,并展望了氧化铝弥散强化铜基复合材料的研究和应用前景。Some processes for the preparation of Al_2O_3/Cu composites with high strength and high electric conductivity are reviewed. From the point of view of thermaldynamics and kinetics, the effects of oxidizing agent and processing parameters of the internal oxidation technology on the mechanical properties and microstructure are discussed in details. The research and development trend of Al_2O_3/Cu composites are also discussed briefly.
