Eutectic high-entropy alloys (EHEAs) have combined both high-entropy alloys and eutectic alloy contributions, with excellent castability and high-temperature application potential. Yet, multielement/triple-phase eutectic high-entropy alloy (TEHEA) designs remain puzzling. This work proposed a new strategy based on an infinite solid solution and pseudo-ternary model to reveal the puzzle of TEHEAs. The designed triple-phase eutectic high-entropy alloys (TEHEAs) with more than seven elements were identified as face-centered cubic (FCC), ordered body-centered cubic (B2), and Laves phase structures. In this work, the alloy C showcases outstanding comprehensive mechanical properties, offering a novel avenue for the design of high-performance EHEAs.

基于无限固溶体和拟三元法的三相共晶高熵合金设计新策略


共晶高熵合金（EHEAs）结合了高熵合金和共晶合金的贡献，具有优异的铸造性和高温应用潜力。然而，多元素/三相共晶高熵合金（TEHEA）的设计仍然令人困惑。这项工作提出了一种基于无限固溶体和伪三元模型的新策略来揭示 TEHEA 之谜。设计的含有七种以上元素的三相共晶高熵合金（TEHEA）被鉴定为面心立方（FCC）、有序体心立方（B2）和Laves相结构。在这项工作中，合金C展示了出色的综合机械性能，为高性能EHEA的设计提供了一种新颖的途径。
