| Abstract Scope |
Additive friction stir deposition (AFSD) is a friction based solid state additive technique, which uses intense stirring to heat and soften metal feedstock material into multi-layer geometries. The balance of heat generation and volumetric flow are crucial for a successful deposit however, due to the current trial and error approach to parameter selection there is little understanding of the impact of a material’s hot strength on deposition performance. This study will be the first to isolate the impact of an aluminum alloy’s hot strength on the AFSD process by depositing Al alloys of various Mg contents under the same processing conditions. Characterization of the microstructure using EBSD along with accurate temperature recordings will be used to better link the effect of AFSD on the resulting microstructure. Mechanical testing in the form of hardness and in plane tensile testing will further our understanding of the processes impact on mechanical properties. |
