| Abstract Scope |
Directed-energy deposition (DED) is a complex process where spatially varying thermal histories impact the microstructure and performance of the printed component. To serve as reliable test specimens, qualification artifacts must reproduce the full range of thermal histories experienced by the DED component. In this work, we present an integrated framework for accelerated qualification of DED components that combines two elements: faster-than-real-time thermal simulations calibrated using in-situ IR data and the design of representative qualification artifacts. Thermal history data are extracted from simulations and used to compare melt pool dimensions and solidification behavior between the DED components and the qualification artifact, ensuring that the qualification artifact reliably reproduces the solidification regimes generated using specific DED process conditions. |
