摘要(Abstract)：

高熵合金具有热力学上的高熵效应、动力学上的迟滞扩散效应、晶格畸变效应、性能上的鸡尾酒效应，通过合理设计高熵合金体系，可以使高熵合金形成简单晶体结构的固溶体组织。研究者将其引入到焊接领域，扩大了高熵合金的应用范围。本文综述了高熵合金作为焊接母材以及中间层材料(钎料)的研究现状。通过对高熵合金在焊接领域的研究总结发现，高熵合金在焊接方面的研究是基于焊缝成分的设计使得焊缝组织为简单晶体结构，进而可以实现异种材料的有效连接。但目前的高熵合金体系有限，缺乏理论指导。针对异种材料连接存在的问题，需扩大合金体系的研究，不断对合金体系成分进行改进，为高熵合金在异种材料焊接中的应用提供理论指导。
