ball milling description
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder As the chamber rotates the media is lifted up on the rising side and then cascades down from near the top of the chamberthe ball milling process and suggests that energy initially accumulates in the Si and W powders after every ball collision Eventually the stored energy overcomes activation energy for the reaction of Si and W to form Ball Milled SiW Alloys: Part I Microstructural and Phase Ball milling was found to proceed in three stages with the amorphization of Si occurring after about 1 hour, followed by the reaction of Si with W to form Si 2 W After about 3 hours a steady state composition is reached This milling process was successfully simulated by assuming constant volume element model and an activated process in which energy is accumulated after every collisionBall Milled SiW Alloys: Part I Microstructural and
