TLDR
In this article, a method for rapidly predicting the formation and stability of undiscovered single phase high-entropy alloys (SPHEAs) is provided, which uses data for 73 metallic elements and rapidly combines them - 4, 5 or 6 elements at a time - using the Miedema semi-empirical methodology to yield estimates of formation enthalpy.About:
