What are high entropy alloys?

High entropy alloys (HEAs) are a class of materials that are comprised of five or more metallic elements in roughly equal proportions. Unlike traditional alloys that are designed to have specific properties, HEAs have a highly disordered atomic structure that leads to unique mechanical, thermal, and magnetic properties. These alloys have garnered significant attention in recent years due to their potential for various applications, including structural materials for high-temperature and corrosive environments, advanced coatings, and as catalysts for chemical reactions. However, their complex composition and properties make their development and optimization challenging, requiring innovative research and development approaches to overcome these obstacles.
