Room-temperature ball milling technique has been successfully employed to fabricate copper-zinc graphene nanocomposite by high-energy ball milling of elemental Cu, Zn, and graphene. Copper powder reinforced with 1-wt.% nanographene sheets were mechanically milled with 5, 10, 15, and 20 wt.% Zn powder. The ball-to-powder weight ratio was selected to be 10:1 with a 400-rpm milling speed.

By increasing milling time, chromium particles tend to break and homogeneous distribution of the average particle size is obtained. During the ball milling of copper composites, powder particles are severely deformed by the impact of the balls which cause an increase in the local temperature, and as a result, atomic diffusion occurs. Furthermore, the density of crystalline defects such as
