Frontiers in high entropy alloys and high entropy functional materials

Abstract Owing to their exceptional properties, high‐entropy alloys (HEAs) and high‐entropy materials have emerged as promising research areas and shown diverse applications. Here, the recent advances in the field are comprehensively reviewed, organized into five sections. The first section introduces the background of HEAs, covering their definition, significance, application prospects, basic properties, design principles, and microstructure. The subsequent section focuses on cutting‐edge high‐entropy structural materials, highlighting developments such as nanostructured alloys, grain boundary engineering, eutectic systems, cryogenic alloys, thin films, micro‐nano‐lattice structures, additive manufacturing,…
