High entropy alloys (HEAs) strengthened by intermetallic (IM) phases can have attractive mechanical performances. However, the design of IM phases in HEAs is challenged by the lack of systematic knowledge on these phases. Here, statistical analyses were used to investigate relationships between IM phases in HEAs and their binary/ternary counterparts. Both structural and compositional considerations of this analysis aim to determine if the IM phases in HEAs are inherited from their binary/ternary subsystems, or if other factors dominate in their formation. Our findings suggest that IMs in HEAs are closely related to binary/ternary IMs that could be formed in the subsystems of the alloys. Such similarities are called structural and compositional inheritances, respectively, and their cause and importance will be discussed.
