high energy ball milling

High-energy ball milling isa ball milling process in which a powder mixture placed in a ball mill is subjected to high-energy collisions from the balls.High-energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that cannot be made by conventional powder metallurgy methods.
