Abstract:Cu/Al composite structure is typical bimetallic composite material that combine pure Al and pure Cu mechanically or metallurgically by specific method. Due to the characteristics of excellent conductivity, light weight and low price, it has become the focus of extensive research. The physical properties and kinds of intermetallic compounds in Al/Cu composites were introduced, and the effect factors of interface diffusion reaction behavior were illustrated. The preparation, interface microstructure and performances of Al/Cu composite were reviewed. The research direction of composite interface and the improvement direction of Al/Cu composite structure prepared by additive manufacturing were prospected. It provides key theoretical basis and technical support for the preparation of Al/Cu composite structure.
Key words: Al/Cu composite; diffusion; intermetallic compounds; preparation technique; interface; laser additive manufacturing
