The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.

Figure 1 shows effect of milling time on particle size of the Al powder. One observes that BM up to 1 hour increases the particle size. More BM after 1 up to 4 hours sharply decreases the particle size, while further milling after 4 hours does not significantly change it. The initial increase in the particle size is attributed to c…
