| Abstract Scope |
The discovery of refractory multi-principal element alloys (RMPEAs) has greatly expanded the explorable compositional space for potential high-temperature structural materials. However, controlling the microstructural development of these alloys and developing physics-based structure-property relationships remains a challenge. In this work, we apply a high-throughput synthesis technique to rapidly investigate such relationships in the Nb-V-Zr-X (X = Mo, Ta, Ti) system. Employing a direct laser deposition method, we vary processing parameters, including deposition order, laser powder, travel speed, and powder feed rate, to rapidly produce alloy libraries with varying compositions and microstructures. The resulting microstructure and its influence on mechanical properties are then assessed with a suite of characterization techniques and nanoindentation experiments at temperatures up to 600 C. Compositional variations, particularly near grain or phase boundaries, are of particular interest. This approach establishes a framework to predict compositional effects on microstructure and properties to accelerate the design of future RMPEA systems |
