| Abstract Scope |
Capturing rapid phase transformations during laser-processing is essential for tailoring the microstructure and mechanical performance of high-entropy alloys. This study centers on FeCrNiCo-based alloys, systematically alloyed with varying Al wt.% to investigate the influence of Al on phase evolution under nonequilibrium conditions. Utilizing in-situ synchrotron X-ray diffraction, we monitor structural changes in real-time during laser-melting. To manage the vast and complex data generated, we implement a high-throughput analysis framework that combines automated Python workflows and machine learning algorithms, enabling efficient extraction of phase fraction and lattice strain evolution. Additionally, the system is designed to support real-time feedback through edge computing hardware or GPU clusters, facilitating dynamic process optimization. By correlating alloy composition and laser parameters with observed phase behavior, this work identifies key processing windows for tuning microstructures. The insights gained advance our understanding of composition-process-structure relationships in HEAs and contribute to the development of alloys with enhanced mechanical properties. |
