Abstract

Some variations provide an aluminum (Al) alloy containing at least 0.1 at % zirconium (Zr) and/or at least 0.1 at % chromium (Cr), wherein the aluminum alloy is in the form of an additively manufactured object. Other variations provide an aluminum-containing powder comprising Al particles, Cr particles, and Zr particles, wherein at least some of the Cr particles as well as at least some of the Zr particles are physically and/or chemically assembled on surfaces of the Al particles, and wherein the aluminum-containing powder contains at least 0.1 at % Zr and at least 0.1 at % Cr. In this invention, the combination of surface functionalization and additive manufacturing has fundamentally created a new composition space of valuable aluminum alloys. The disclosed Al alloys are strong, thermally stable, and corrosion-resistant.
