ABSTRACT
Aluminum alloy 7075 (Al 7075) with a T73 heat treatment is commonly used in aerospace applications due to exceptional specific strength properties. Challenges with manufacturing the material from the melt has previously limited the processing of Al 7075 via welding, casting, and additive manufacturing. Recent research has shown the capabilities of nanoparticle additives to control the solidification behavior of high-strength aluminum alloys, showcasing the first Al 7075 components processed via casting, welding, and AM. In this work, the properties of nanoparticle-enhanced aluminum 7075 are investigated on welded parts, overlays and through wire-based additive manufacturing. The hardness and tensile strength of the deposited materials were measured in the as-welded and T73 heat-treated conditions showing that the properties of Al 7075 T73 can be recovered in welded and layer-deposited parts. The work shows that Al 7075 now has the potential to be conventionally welded or additively manufactured from wire into high-strength, crack-free parts.
