Research Progress on Composition Design of Multicomponent Eutectic High Entropy Alloys.

Eutectic high-entropy alloys (EHEAs) have unique properties, making them a significant sub-branch of HEAs. Researchers are interested in their high strength, good castability, and ductility. However, due to the lack of a complete phase diagram database and previous research results, the traditional trial-and-error method will greatly reduce the research efficiency, and the composition design of EHEAs faces many difficulties. This paper summarizes the recent proposals of the thermo-dynamic factors that have a decisive role in the design of EHEAs. Regarding previous research, we discussed the methods for designing the main eutectic compositions currently used in research. These methods aid in developing novel approaches to fabricating EHEAs.
