| Abstract Scope |
Additive Friction Stir Deposition (AFSD) exists as a novel solid-state manufacturing process with hopes of repairing damaged non-fusion-weldable materials and building complex structures with wrought-like properties. In this study, aluminum alloys A206 and 6061 are joined together to probe the microstructural evolution at dissimilar material interfaces before and after conventional heat treatment. Due to the solid-state thermomechanical development of complex yet predictable microstructural textures and precipitation mechanisms, this study combines advanced metallographic analysis, spatially resolved diffraction, multi-dimensional mechanical testing, and fractography to elucidate post-process failure mechanisms from joining dissimilar materials via AFSD in order to recommend general process-property relationships for other alloy combinations. |
