High-Energy Ball Milling - an overview | ScienceDirect Topics
High-energy ball milling is a 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.High energy ball milling process for nanomaterial synthesis,besides materials synthesis, high-energy ball milling is a way of modifying the conditions in which chemical reactions usually take place either by changing the reactivity of as-milled solids (mechanical activation — increasing reaction rates, lowering reaction temperature of the ground powders)—or by inducing chemical reactions during millingHigh-Energy Ball Milling | ScienceDirect,It involves the use of a high energy ball mill to initiate chemical reactions and structural changes.
