| Abstract Scope |
The growing demands of solidification defect-free large-area rapid metal 3D printing have transitioned the manufacturing paradigms from fusion-based additive manufacturing to solid-state additive manufacturing. Additive friction extrusion deposition, or AFED, is a novel friction-based solid-state additive manufacturing method that uses local friction to soften the metal feedstock by grain-refinement before deposition, extrudes this softened metal out as a paste, and then uses secondary friction between the extrusion die surface and the deposited material to frictionally deposit the softened material as a 3D material layer. In this research, the AFED method is used to successfully deposit large continuous and overlapped layers of aluminum 6061-T6 alloy intended for cladding operations in safety-critical large industrial components. The effect of overlapping distance, process parameters on steady-state continuous layer printing, and interfacial characteristics between the substrate and the printed layer are further demonstrated. The deposited layers showed significant grain refinement, precipitate dissolution, and wrought microstructure. |
