A new preparation technology of alumina dispersion strengthened copper matrix composite was introduced and the influence of preparation parameters on the microstructure and properties of the composite was studied. The results show that the internal oxidation treatment in the nitrogen-based atmosphere can also obtain a good thermal stability of alumina dispersion strengthened copper matrix composites; preparation process parameters, especially the internal oxidation process has a significant effect on the material properties. Due to the change of media and process, under the premise of ensuring the performance of composite material, the production cost is reduced and the product quality is stabilized. This process is helpful for the large-scale production of alumina dispersion-strengthened copper matrix composite material.
