High-entropy Alloys for Advanced High-temperature Applications

High-entropy alloys (HEAs) have redefined metallic materials design by exploiting multi-principal element compositions to achieve exceptional properties. Due to the diverse microstructures together at multiscale, these alloys are expected to exhibit remarkable thermal stability, creep resistance, and oxidation resistance beyond conventional superalloys. By tuning compositional complexity and microstructural engineering—such as short-range ordering, nanoprecipitation strengthening, and grain-boundary characters and distributions—these alloys promise revolutionary applications in aerospace, power generation, and hypersonic vehicles.

Developing next-generation ultra-strong, ductile alloys with exceptional thermal resistance has always been a key driver of progress in modern industries, particularly aerospace. The integration of innovative high-entropy alloys with advanced manufacturing techniques is paving a new way toward this goal. By enabling lighter, stronger, and more heat-resistant alloys and components, we can significantly contribute to energy conservation, emission reduction, and carbon neutrality.
