There is a small amount of equiaxed Cu in the composite for ball milling 40 h, all transformed into creeping Cu when the ball mill is 60 h. Because of the severe plastic deformation during the ball milling process, the spherical powder is rolled into flake structure, so as to achieve the effect of "powder microrolling."

Ball milling can be used for "mechanical alloying" of powders, either to form compounds ( formation of tungsten carbide from WO 3 + C or from W + C by direct carburization [7]) or to reduce the particle, crystallite, and grain size of an existing powder ( formation of nanostructured WCCo powders [8,9]).

FESEM Analysis Ball Milled Powder. The morphology of SiC particles after 40h of milling time, as observed under FESEM is shown in Fig. particles are greatly fractured and larger fraction of nano size particles in 40h milled samples are observed, this could be due to excess work hardening and enhancement of brittleness of the particles by milling [21, 22].

However, a very long ball milling time is not needed for powder refinement. Moreover, after the powders change from microscale to nanoscale, agglomeration may occur with longer milling time [26]. In addition, larger active specific surface area would be produced due to the change in particle size range from micron to nanoscale.
