Refractory High Entropy Alloys

Metallurgy and Design for Ultra-High Temperature Performance

Master the next frontier of materials science where conventional superalloys reach their melting point.

Strategic Objectives

• Decode the complex phase stability of Group IV, V, and VI elements.

• Master the mechanisms of Body-Centered Cubic (BCC) crystal structures.

• Solve the critical trade-off between high-temperature strength and oxidation resistance.

• Implement advanced computational strategies for multi-principal element discovery.

The Core Challenge

Modern aerospace and energy demands have outpaced the thermal limits of nickel-based superalloys, requiring a radical shift in metallurgical design.
