Mechanical alloying uses a mixture of balls and elemental powder to create a micro alloyed composite powder in an attritor or in another high energy ball mill (Figure 1401.02.03). The repeated milling, cold welding, fracture and rewelding of the metal powder leads to a homogenized material with a uniform dispersion of inclusions. A

The impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for high-speed milling. Schematic view of motion of the ball and powder mixture.
The MMC are mainly prepared by two routes namely Powder metallurgy and Casting method. The powder metallurgy route mainly consists of three stages Mixing of the powders compaction and sintering. The mixing can be achieved by many methods and one of such method is by utilizing ball milling equipment. The ball mill equipment consists of hollow .
