| Abstract Scope |
Metallic functionally graded materials (FGMs) possess intriguing graded material properties, but conventional manufacturing methods have hindered the design and manufacturing of them. Additive manufacturing, especially directed energy deposition (DED), allows for point-to-point build-up of a part, and is therefore a preferred fabrication method for FGMs. Magnetic field assisted DED (MA-DED) uses external magnetic fields to influence the molten metal flow during DED, allowing for locally manipulating the solidified material microstructures, consequently leading to graded mechanical properties. Nevertheless, how the magnetic field influences the resultant mechanical properties is not well-understood. Here, we leverage in-situ high-speed IR and synchrotron X-Ray imaging to collect data on the molten metal dynamics during the MA-DED process. Using a combination of analytical, simulation, and machine learning techniques, we establish a quantitative relation between the magnetic field parameters and the resultant microstructure and mechanical properties, which provides a foundation for developing metallic FGMs in MA-DED. |
