Design of new, ductile refractory high-entropy alloys driven by first-principles calculations

Refractory high-entropy alloys (RHEAs) represent a new paradigm of high-temperature materials for energy conversion and production applications. RHEAs would hold the promise of increasing the operating temperature by up to 300-500°C compared to Ni-based super alloys, thereby increasing energy efficiency and reducing emissions. However, insufficient room-temperature ductility in most RHEAs developed so far is a major issue. This project addresses this concern, and will accelerate and improve the possibility to identify new ductile RHEAs using first-principles calculations and experimental verification at partners.
