Abstract Based on virtual solvent (a virtual homogeneous material consisting of identical “average” atoms) concept, the methods have been developed to determine interatomic distance, atomic size misfit, and elastic modulus misfit in multiprincipal element alloys with components having the crystal structure differing from that of the alloy. The combined different methods results in a number of models to calculate solid solution strengthening. These models are assessed with the view point of the best fit to experimental data. The models providing the most reliable strengthening prediction can be used for an evolutionary design of high strength and chemical resistant of multicomponent alloys.
