Abstract Scope We are investigating the micro- and nanostructural evolution of AA7075 deposited by additive friction stir deposition (AFS-D), a solid-state additive manufacturing technique. Three conditions were considered to evaluate the AFS-D process and subsequent heat treatment on the precipitate structure of the depositions. AA7075-T651 feedstock rod was deposited by AFS-D and then subjected to a post-heat treatment procedure of solutionizing (at 490ºC for 1 hr), quenching, and aging (at 120ºC for 24 hr). Using EBSD mapping, we observed a clear grain refinement from the AFS-D process, but not significant grain growth from the post-heat treatment. STEM imaging and atom probe tomography showed that the MgZn2 phases were dissolved by the AFS-D process and that the natural aging did restore some nanophase precipitates. After full post-heat treatment, the nanophase MgZn2 precipitate structure was completely restored and resulted in full strength for the material as observed in tensile testing of heat treated material.
