Derivation of unit cell volume, and lattice parameter of cubic high entropy alloys from volume size factors

An equation has been derived to predict unit cell volume of high entropy alloys, HEA's, by two different methods. In the first method, a HEA is considered as a mixture of solid solutions. Based on an equation previously reported to calculate unit cell volume of intermetallic compounds, an expression to calculate unit cell volume of HEA's was obtained. In the second method, a HEA is modeled as a mixture of solute element atoms surrounded by...
