High-entropy alloys (HEAs) are multi-component single-phase alloys. Many studies have been carried out to develop new HEAs with superior mechanical properties in cryogenic conditions. CALPHAD approach allows to calculate multicomponent phase diagrams by using thermodynamic properties of their sub-systems. Therefore, it can be an efficient way to develop a new HEA system within a compositional range. In the present study, HEA constitution map demonstrating compositional range where single solid solution exists is developed. New fcc HEAs are developed with this constitution map. They have similar or better cryogenic mechanical properties compared with well-known Cantor alloy. This constitution map can be used for another new HEA alloy design.
