Abstract Scope |
Functionally graded materials (FGM) can be prepared using directed energy deposition (DED) techniques, enabling multifunctionality in alloy components. In this talk, I will share some experiences printing FGM using different DED techniques guided by ICME. The talk will present some case studies illustrating the advantages of using the CALPHAD-based ICME technique in additive manufacturing (AM) design. In addition, severe challenges to characterization experiments and computational modeling due to the design requirement in AM will be discussed. A case study that integrates the CALPHAD, ICME, machine learning, and high-throughput experiments will be highlighted since it demonstrates how DED is applied as part of the combined approach to alloy development through compositional screening. However, such a study also emphasizes the importance of location-specific design in AM. |
