Abstract: A method of forming an additively manufactured aluminum part includes establishing an arc between a metal-cored aluminum wire and the additively manufactured aluminum part, wherein the metal-cored aluminum wire includes a metallic sheath and a granular core disposed within the metallic sheath. The granular core comprises aluminum metal matrix nano-composites (Al-MMNCs) that comprise an aluminum metal matrix and ceramic nanoparticles. The method includes melting a portion of the metal-cored aluminum wire using the heat of the arc to form molten droplets. The method includes transferring the molten droplets to the additively manufactured aluminum part under an inert gas flow, and solidifying the molten droplets under the inert gas flow to form deposits of the additively manufactured aluminum part.

Abstract: The present disclosure relates to a metal-cored welding wire, and, more specifically, to a metal-cored aluminum welding wire for arc welding, such as Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW). A disclosed metal-cored aluminum welding wire includes a metallic sheath and a granular core disposed within the metallic sheath. The granular core includes a first alloy having a plurality of elements, wherein the first alloy has a solidus that is lower than each of the respective melting points of the plurality of elements of the first alloy. The granular core comprises aluminum metal matrix nano-composites (Al-MMNCs) that comprise an aluminum metal matrix and ceramic nanoparticles.
