| Abstract Scope |
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 aimed to determine how the IM phases in an HEA were affected by their counterparts in the binary/ternary subsystems of that alloy, and if other factors dominate in the formation of these IM phases. Our findings suggest that IMs in HEAs were closely related to binary/ternary IMs that could be formed in the subsystems of the alloys. Such similarities were called structural and compositional inheritances and their importance will be discussed. |
