A new screening methodology is proposed to aid in the development of high-entropy alloys (HEAs). This approach takes into account three commonly used criteria and methods to guide the design of HEAs: empirical parameters, binary phase diagram inspection and the Calculation of Phase Diagrams (CALPHAD) method. In addition, two novel concepts are introduced: a criterion to evaluate the likeliness of single phase solid solution in an alloy system's non-equiatomic compositional space, and a binary priority list, which allows us to make the employed in-house thermodynamic database a more reliable tool for solid solution screening in a time-effective manner.
