Solid solution strengthening in multicomponent fcc and bcc alloys: Analytical approach

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.

Automated summary

Novel methods based on the virtual solvent concept are used to determine interatomic distance, atomic size misfit, and elastic modulus misfit in multicomponent alloys with different crystal structures. The combination of these methods leads to models for calculating solid solution strengthening, with the most reliable models being suitable for the design of strong and stable multicomponent alloys.
