High-entropy alloys (HEAs) have many attractive properties, while the thermodynamic mechanism and general behavior of the spinodal decomposition in HEAs remain unknown. In this work, we conduct an experimentally consistent calculation of the spinodal decomposition of HEAs. Against the “high mixing e...
