  • CRYOMILLING OF ALUMINUM-BASED AND MAGNESIUM-BASED METAL

    CiteSeerXDocument Details (Isaac Councill Lee Giles Pradeep Teregowda) Ball milling has been shown to produce nanostructures in metal powders through severe repetitive deformation. Ball milling at cryogenic temperatures (cryomilling) is more effective in this capacity due to the low temperature by slowing recovery and minimizing diffusion distances between different components.
