| Abstract Scope |
Additive friction stir deposition (AFSD) is a novel solid-state additive manufacturing approach for metallic materials that results in enhanced mechanical properties. The intense shear deformation with enormous frictional heat during AFSD results in layer-by-layer deposition of very fine microstructure material. In this study, a powder metallurgy route was used for deposition of high-strength Al-6Mg-1Sc-1Zr and Al-6Mg-2Sc-1Zr (wt.%) using the AFSD. Contributions from the grain boundary strengthening, solid solution strengthening, and precipitate strengthening at room temperature has been discussed using the numerical modeling for AFSD Al-Mg-Sc-Zr alloys. The increase in strength and ductility was established through multi-scale mechanical testing and correlated with microstructure including the nano precipitates. In addition, the heat transfer and material flow numerical modeling was used to understand the heat generation due to friction and plastic deformation. |
