Introduction Click to copy section linkSection link copied! High-entropy alloys (HEAs) are a new class of materials characterized by their remarkable structural and functional properties. (1−4) Several efforts have been made to define HEAs, and it is generally accepted that they consist of at least five principal elements mixed to form a single-phase solid solution. (5,6) The mixing entropy (ΔSmix) is the thermodynamic parameter typically used to classify multiprincipal element alloys.
