Microstructure and properties of cold-drawn Cu and Cu-Fe alloy wires

open access: yes, 2022
Copper and Cu-Fe alloy wires were cold drawn at room temperature, and the microstructure and properties were characterized and analyzed. The results show that, at the same drawing strain, the strength and ductility of Cu-Fe wires are higher than those of
