| Abstract Scope |
Additive manufacturing (AM) of functionally graded materials (FGMs) enables novel design and joining capabilities for next-generation energy technologies. However, predicting microstructures and properties is challenging due to complex thermal histories, especially as material properties change spatially. To address this, we systematically investigated the microstructural evolution in AM FGMs from titanium to tantalum. Multiple instances of the same component were produced, each terminating at a different intermediate layer, then cross-sectioned perpendicular to the “terminal” melt pool in each sample to capture slices of microstructure development across build stages. Characterization using SEM, EDS, EPMA, and EBSD enabled tracking of phase formation, interdiffusion, and grain structure changes throughout the build. In situ thermocouple data was compared to analytical simulations, showing the importance of utilizing temperature-dependent property models to track phenomena. These insights provide a foundation for optimizing AM for FGMs to achieve precise spatial tailoring of properties for performance in advanced energy environments |
