| Abstract Scope |
Next generation material advancements in the defense and energy sectors will be obtained by integrating novel characterization tools, modeling tools, and machine learning to advance our understanding of the intimate, location-specific connection between processing, structure, and properties of these materials. As a building block towards this realization, this presentation describes the integration of synchrotron X-ray diffraction measurements, finite element simulations, and machine learning techniques for the development of residual stresses in additively-manufactured (AM) thin wall nickel superalloy plates built with a range of dimensions. Local thermal histories informed by a fast acting discrete source model are used as inputs for the thermo-mechanical finite element modeling of the AM solidification process. The residual stresses induced during the solidification process are then compared to energy-dispersive X-ray diffraction measurements of the as-built plate structures. Perspectives on integration of X-ray diffraction experiments, modeling, and machine learning, and the current technology gaps will be discussed. |
