Entropy contributions to phase stability in binary random solid solutions

npj Computational Materials, 2018
High entropy alloys contain multiple elements in large proportions that make them prone to phase separation. These alloys generally have shallow enthalpy of mixing which makes the entropy contributions of similar magnitude.
