摘要：

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 Fex(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.
