High-entropy alloys (HEAs), which are formed by combining nearly equal parts of several primary metals, are an emerging class of advanced materials that hold great potential for creating materials with superior mechanical, thermal, and catalytic properties. New research offers key insights into how HEA nanoparticles behave under high-temperature oxidizing environment and sheds light on future design options of highly stable alloys under complex service conditions.
