Ball Milling SpringerLink
网页2016年6月19日 In the process of ball milling, interdiffusion between the components is forced by the mechanical action of repeated fracture and welding of elemental particles. The decreased particle size reduces the diffusion distances between components. Diffusion is further helped by the increased defect density and a local rise in temperature.
