DoE EPSCoR: Discovery, Design, Synthesis and Testing of High Performance Structural Alloys

The research objective of the proposed 3-year study is to establish a foundational metallurgical understanding of the composition-structure-property relationships governing advanced structural alloys, including multi-principal element alloys (MPEAs), which are also known as high-entropy alloys. Existing metallurgical knowledge is not sufficient to reliably design, develop or process MPEAs. To address this, the proposing team will take a multidisciplinary and multi-scale approach that integrates experiment and computation to screen MPEA systems, and build a comprehensive understanding of phase formation & stability, alloy structure and elemental distribution, and the defects and mechanisms that govern mechanical behavior. The combined experimental-computational research effort will yield sufficient knowledge to identify, predict and design novel application-relevant structural alloys.
