| Abstract Scope |
This presentation will discuss the role of materials informatics in the design of multi-component systems. The primary focus will be on the design of high entropy alloys and the challenges in trade-offs between strength, ductility and various environmental effects. To address the limitations in traditional regression approaches which can generate large amounts of data rapidly but do not account for the complexities in unknown property data, an approach for introducing a new design index is discussed. This approach is designed to capture the interplay between chemistry, microstructure and phase stability, which allows us to identify chemical design rules for improving mechanical properties with minimal trade-offs. The approach permits one to understand how different and/or the same alloying element has a multifunctional role in defining engineering properties. Through these models, it is identified the difference in structure-property relationships between the optimized and standard alloys. |
