| Abstract Scope |
Refractory multi-principal element alloys have been shown to demonstrate excellent yield strength at elevated temperatures often outperforming conventional superalloys. However, exploring their immense compositional space is time-consuming. High-throughput synthesis methods are needed to generate comprehensive material libraries that i) withstand the challenges of processing refractory elements ii) contain length scales relevant for the mechanical responses of structural alloys. To address this gap, we introduce the SMART (Synthesis through Mixing and Rapid Thermal processing) method, a novel approach to rapidly create bulk-like material libraries. These SMART libraries are characterized via scanning electron microscopy and energy dispersive spectrometry to determine composition, followed by micro indentation to assess hardness. We show that SMART libraries capture the hardness trends observed in individually fabricated samples of the same compositions. Thermo-Calc simulations using the TCEA7 database further show that Laves phase fractions correlate with the hardness rankings, offering a predictive link between microstructure and mechanical behavior. |
