Deformation Cu-based in-situ composites are functional materials with great application potential. Cu-based in situ composites,which have ultra-high strength coupled with good conductivity, are one of the hotspots and developing tendency of high strength and high conductivity copper base composites. Research situation of Cu-based in situ composites was summarized in this paper. The microstructure evolution, strengthening and electric conduction mechanisms of this materials were introduced. The fabrication processes and combined properties of deformation processed Cu-based in situ composites were also summarized. The developing tendency of the composites was finally presented.
