共晶高熵合金（EHEAs）作为高熵合金（HEAs）的一个分支，因其优异的浇注性、铸态组织细小均匀、强度高、延展性好等优点，正成为金属材料界研究的新热点。一些EHEAs已显示出良好的工业应用潜力。本文综述了EHEAs的发展历史、有趣的凝固组织和力学性能以及设计策略，并对其未来发展前景进行了展望。(C) 2020材料学报Elsevier Ltd.出版。版权所有。
Eutectic high-entropy alloys (EHEAs), as a sub-group of high-entropy alloys (HEAs), are becoming a new research hotspot in the metallic materials community because of their excellent castability, fine and uniform microstructures even in the as-cast state, high strength, and good ductility. Some of the EHEAs have shown promising potentials for industrial applications. Here, the history, interesting solidification microstructure and mechanical properties, and the design strategy of EHEAs are reviewed, and their future prospects are outlined.
