Abstract Scope |
Direct Energy Deposition (DED) is a widely utilized AM process to produce large components and repair damaged parts. Attempts have been made to obtain improved deposition-rates and mechanical properties by applying Metal Matrix Composite (MMC) powders to conventional DED process. However, the Multiphysics phenomena including melt pool evolution, nucleation, and phase transformation which are affected by the reinforcements are highly complex, and it hinders building PSP linkage for the MMC AM process. To fill this gap, computational analysis consisting of Thermo-Fluid and Cellular Automata model is constructed in this study; first one to estimate the melt pool formation and distribution of reinforcements in the melt pool, latter to predict the microstructure. Unlike previous studies, the results demonstrated that the analysis used in this study enables building linkage between Process and Structure for the MMC AM process and gives possibilities of optimizing the process to achieve the targeted quality and performance. |
