| Abstract Scope |
Solid state additive manufacturing techniques are used to overcome the disadvantages of fusion based additive manufacturing. Friction stir additive manufacturing (FSAM) holds promise in this this regard with improved microstructure and structural performance. This study investigates the microstructure and mechanical properties of Al6061-T6 prepared by FSAM, and employs a Coupled-Eulerian Lagrangian finite element model to predict the tool reaction forces, stresses, and temperature distribution, which is used to predict the process parameters for a sound weld. The model also predicted the temperature history of the plates, based on which the microhardness of the material is predicted. Based on modeling and experiments, the quality of the material fabricated is investigated in terms of process parameters. Tensile tests were conducted in the transverse direction to observe the strength and ductility. The microstructure of the processed part is studied and used to explain the behavior of the material. |
