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].
