Modeling of solid solution strengthening in FCC alloys: Atomistic simulations, statistical models and elastic continuous approaches

Abstract

Solid solution strengthening is a technologically important mechanism controlling the strength of a wide range of alloys. Understanding and predicting the temperature-dependent yield stress of these alloys requires to model the interactions between dislocation and solutes atoms across a wide range of time and length-scales, and therefore necessitates the development of multiple numerical methods (atomistic calculations, statistical approach and continuous elastic models) that are reviewed in this article. The advantages and drawbacks of each methods as well as their complementary character and the connections between them are highlighted.
