High-entropy alloy（HEA）

which breaks the design concept of traditional alloy

is a new type of alloy composed of multiple main elements.However

most high-entropy alloys usually have poor fluidity and castability as well as larger compositional unevenness

which is adverse to the large-scale industrial application.Eutectic high-entropy alloys（EHEAs）exhibit the characteristics of high-entropy alloys and eutectic alloys simultaneously

which can reduce casting defects and have unique advantages in high-temperature application.Therefore

it is of great significance to design and preparation of eutectic high-entropy alloys.The research progress of melting eutectic high-entropy alloys at home and abroad was reviewed.The phase composition and properties of the alloys as well as the growth characteristics and mechanism of the eutectic morphology were introduced.Subsequently

the phase formation law of eutectic high-entropy alloy and the design method of eutectic composition were summarized.Finally

the forward research direction of eutectic high-entropy alloy was prospected.
