| Abstract Scope |
Multi-Principal Element Alloys (MPEAs) are promising candidates for next-generation structural materials due to the enhanced mechanical, physical, and functional properties achievable through tuning composition. However, the vast compositional spaces that must be navigated in the discovery and design of these alloys demand modern synthesis and characterization approaches that can quickly screen complex composition-structure-property relationships. This work discusses how combinatorial material libraries synthesized via DC Magnetron-Sputtering can be used in conjunction with high-throughput characterization methods such as Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-Ray Diffraction (XRD), and nanoindentation to screen MPEA design spaces. The MoTaNbCrZr systems is presented as an example of how such investigations offer insights into the complex behavior of MPEAs. The generated datasets constitute an experimental knowledge base which future computational and machine learning models may use when screening promising alloy candidates for extreme applications, thus accelerating discovery of novel materials. |
