high-energy mills. This former definition is not also adapted because the use of dry processing conflicts with examples of moist process of some materials [2]. A wider definition was proposed by Schwarz [3], for whom mechanical alloying is a high-energy ball mill technique employed to prepare powder alloys with unequal microstructure. On the
It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960.
