| Abstract Scope |
Refractory high entropy alloys (RHEAs) have garnered significant interest due to their potential for superior high-temperature performance. However, despite high melting temperatures combined with promising mechanical properties, their practical applications are limited by insufficient oxidation resistance. Systematic exploration of passivating elements and their interplay with other elements plays a key role in unlocking the full potential of RHEAs.
This work explores a high throughput computational and experimental framework designed to enhance the oxidation resistance of RHEAs. Passivating elements are added to create compositional gradients using directed energy deposition. Our findings highlight compositional trends towards improved oxidation resistance, paving the way for developing next-generation materials for extreme environments. This work accelerates the discovery process and provides a robust methodology for designing advanced materials with tailored properties. |
