a planetary mill at room temperature under controlled atmosphere of argon ( % pure). Ball to powder weight ratio was 15:1 and the mill revolved at 300 rpm disc speed.
Highenergy ball milling was used to prepare the nanocrystalline powder; it was followed by consolidation using spark plasma sintering. During highenergy ball milling, particles are subjected to repeated ﬂattening, cold welding, fracturing and rewelding. When two milling balls collide, a certain amount of powder is trapped
general categories: crushing and milling. Crushing typically means reducing large chunks to sizes about ½ in. to ¾ in. in diameter or smaller. Milling usually means reducing material to sizes in the low micron or even nanosize range. Crushing mostly is done dry while attrition milling .

Ball milling: Two or more metal powders are ballmilled in a high speed chamber using tungsten or carbide balls. This process results in production of mechanically alloyed intermetallics. Powder particles of nano size could be produced by ballmilling process. Ball milling is also used for producing fine particles from brittle metals.

ABSTRACT.
mechanical properties of the extruded composites usually increase due to their reﬁned microstructure, fewer voids and less segregation as well as the uniform distribution of their reinforcement and recrystallized grains [16–18]. Du et al.  fabricated an Al/20 vol% BN composite by planetary ball milling, hot pressing, and hot extrusion at 550 C.
materials by ballmilling. The developed method, called "mechanical alloying", brought a new life to the ancient technique . Mechanical Processing Mechanochemistry chemical conversion of solids facilitated by mechanical processing, or grinding.
