Light metal has gained tremendous industry interest in fuel economy by applying light metal to reduce the weight of constructions and vehicles. With high-strength aluminum alloys as deposition material, additive manufacturing achieves significant weight saving with only minor compromise in strength. However, despite the superior strength-to-weight ratios of these high-strength aluminum alloys, they are usually non-printable due to hot cracking susceptibility. In this work, Wire Arc Additive Manufacturing (WAAM) was used to print nanoparticle enhanced high strength aluminum components. The resulting parts were crack-free with exceptional grain morphology and superior mechanical properties. Despite repeated heating cycles during the WAAM process, the incorporated nanoparticles are able to control the grains to remain stable and uniform throughout layers. This study demonstrates the great potentials when WAAM combines with Nanotech Metallurgy.
