Research Status and Development Trend of Particle Reinforced Copper Matrix Composites

Copper and copper alloys have excellent electrical and thermal conductivity and ductility, but poor mechanical properties limit their further application in industrial fields. Compounding is considered to be one of the effective ways to improve their comprehensive properties. The selection basis of common reinforcing phases for particle reinforced copper matrix composites is summarized. The preparation methods, key factors affecting the performance and the performance control measures of particle reinforced copper matrix composites are reviewed. Finally some new ideas for future research directions are put forward on the basis of the existing problems in preparation.
