Based on virtual solvent concept,novel methods are developed to determine interatomic distance,atomic size misfit,and elastic modulus misfit in multicomponent alloys with components having the crystal structure differing from that of the alloy.The combination of the different methods results in a number of models to calculate solid solution strengthening.These models are assessed with view point of the best fit to experimental data.The models giving the most reliable strengthening prediction can be used for an evolutionary design of strong and stable multicomponent alloys.
