| Abstract Scope |
Laser-based directed energy deposition (DED) is an emerging approach for rapid fabrication of complex concentrated alloys (CCAs), which involves rapid heating-cooling cycles resulting in various phases and transient phases in CCAs. Designing targeted CCA microstructures to achieve specific mechanical properties or corrosion performance necessitates a predictive understanding of the dynamic microstructural evolution during DED. To achieve this, recent global efforts have focused on developing in-situ synchrotron X-ray diffraction methods during additive manufacturing, utilizing portable DED simulators at beamlines. However, the high latency associated with data analysis in these experiments poses a significant challenge to rapidly discovering the relationships between DED processing, microstructure, and properties in CCAs. Our approach overcomes this challenge by integrating in-situ synchrotron methods with low-latency, on-the-edge data analysis. This work presents the developed database libraries that benchmark data analysis latency and establish relationships between alloy composition, DED processing parameters, mechanical properties, and corrosion resistance for selected CCAs. |
