As the milling time increases, Al and mainly Cu peaks decrease significantly. The θ peaks seems to reach its maximum intensity in the powder milled for 2 hours, decreasing thereafter. Fe peaks remain visible even in powders milled for 5 hours. It seems that the lower solubility and diffusivity of Fe than Cu in Al is responsible for this effect.Ball Mill Rotation On Belts.
