Microstructure of as-deformed and annealed Cu-Nb composite wires were investigated by SEM and TEM. Hardness of the as-deformed and annealed samples were measured. The results showed that both the interface density and the rate of interface-increasing increased with increasing strain. When the microstructure reached nano-scale (strain=24.8), the interface density showed a sharp increase which induced a rapid increase in hardness, accompanied by formation of stacking faults and rotation grain boundaries in Cu. During the annealing, the size effect impacted the evolution of microstructure of the multi-scale Cu matrix. The evolution can be classified in to three stages with respect to annealing temperatures: recovery and recrystallization of large Cu, while that of the nano Cu were restrained; recovery and recrystallization of nano Cu; spheroidization and coarsening of Nb.
Key words： Cu-Nb composite wire; interface density; stacking fault; size effect
