Feb 03, 2012 It was found that the addition of nano size SiC greatly influenced the morphological characteristics of powder mixture, and also worked hardening of the powder to decrease the time taken to reach a steady state. Furthermore, Al became smaller crystallite size during ball milling of Al powder in the presence of SiC particles. 3.2

The objective of milling is to reduce the particle size and blending of particles in new phases. The different type of ball milling can be used for synthesis of nanomaterials in which balls impact upon the powder charge [12]. High-energy ball milling is a convenient way to produce nanosized powders. It is the most common method reported in the

Ball milling is often used not only for grinding powders but also for oxides or nanocomposite synthesis and/or structure/phase composition optimization [14,41]. Mechanical activation by ball milling is known to increase the material reactivity and uniformity of spatial distribution of elements [63]. Thus, postsynthesis processing of the materials by ball milling can help with the problem of minor
