In this work, the limitations of the current design strategies of eutectic multi-principal element alloys (EMPEAs) have been investigated and addressed using a novel design approach that utilizes Scheil solidification simulations. The proposed design approach was experimentally verified by demonstrating a eutectic in the Al-Fe-Ti-V-Zr alloy system, in which Fe was identified as the eutectic forming element (EFE). Vacuum-arc-melting was utilized to fabricate the precisely designed Fe_x(AlTiVZr)_100-x (x = 70, 73, and 75) alloys. The alloy, with x = 73, was found to possess a fully eutectic microstructure corroborating the proposed design approach.

在这项工作中，使用一种利用 Scheil 凝固模拟的新型设计方法研究并解决了共晶多主元素合金 (EMPEA) 当前设计策略的局限性。通过在 Al-Fe-Ti-V-Zr 合金系统中展示共晶，对所提出的设计方法进行了实验验证，其中 Fe 被确定为共晶形成元素 (EFE)。利用真空电弧熔炼来制造精确设计的 Fe _x (AlTiVZr) _100-x（x = 70、73 和 75）合金。发现 x = 73 的合金具有完全共晶的微观结构，证实了所提出的设计方法。
