| Abstract Scope |
Microstructure evolution in metals and alloys during traditional and advanced manufacturing arises from complex thermo-mechanical-chemical signatures. While emerging computational models describe these correlations, they often require extensive calibration to capture solidification, phase transformations, and elastic/plastic deformation. The first part of this talk highlights pioneering work by global researchers using laboratory- and facility-based techniques to interrogate these phenomena. The second part focuses on non-equilibrium solidification under steep thermal gradients and high liquid-solid interface velocities, presenting new, unpublished results. Challenges in achieving sufficient temporal and spatial resolution during rapid solidification will be discussed. In the third part, discussions will focus on how scattering and spectroscopy techniques, both at the laboratory scale and at national facilities, enable deeper insights into microstructure evolution during solid-state additive manufacturing. Finally, the talk will emphasize the critical need to translate these scientific observations into practical pathways for qualifying additively manufactured components for demanding structural applications. |
