Dispersion of Carbon Nanotubes in AA6061

Multi-wall carbon nanotubes (MWCNT), up to 2% in weight, were dispersed into AA6061 aluminium alloy by high-energy ball milling (HEBM) process, for further consolidation into extruded metal-matrix composites (MMC) bars. Three distinct routes were employed: the simple one step loading of materials inside the milling vials, an ultrasonically assisted dispersion of MWCNT and alloy powder into
