| Abstract Scope |
Directed energy deposition (DED) enables rapid synthesis of compositionally varied alloy samples, facilitating the efficient exploration of novel material systems. By allowing precise, localized deposition of elements, DED reduces the time and material required to fabricate and test new structural alloys with tailored properties and performance. Realizing this potential, however, requires equally rapid methods to characterize the resulting microstructures and compositions.
Here, we describe the discovery and development of alloys within the Al-Ti-Fe-Si system, selected for the prospective availability of these elements in the lunar environment. We deposit combinatorial arrays of millimeter-scale samples using DED, and characterize them with a newly developed laboratory instrument that enables simultaneous high-throughput XRD and XRF.
The integration of a high-brightness source, low-noise detector, robotic sample handling, and autonomous data streaming and analysis allows for rapid collection of large datasets. This provides critical structural and compositional information, helping to close the AI-driven discovery-loop. |
