Abstract Scope |
Additive friction stir deposition is a solid-state additive manufacturing process where the deposited material's microstructure is very similar to wrought material. The microstructure evolution during the process depends on their themo-mechanical history. So, this work aims to analyze the effect of thermo-mechanical history on the microstructure evolution of additive friction stir deposited Al6061. A three-dimensional CFD based numerical is developed to capture the thermo-mechanical history during the process. The numerical model consists of the conservation of momentum, mass, and energy. Here, additive friction stir deposition of Al6061 is carried out at 300 rpm tool rotational speed and 2 mm/s tool velocity. An EBSD scan was performed on the deposited material to analyze the microstructure evolution. The experimental results suggest homogenous microstructure evolution in the deposition region, which also matches with consistent thermo-mechanical history. |
