| Abstract Scope |
Modeling abnormal grain growth remains challenging because it requires accurate representation of anisotropic interfacial properties, particularly the dependence of grain boundary energy on interface inclination. While isotropic phase-field models can capture normal grain growth, they cannot fully represent anisotropic interfacial properties. This study utilizes an inclination-dependent anisotropic phase-field model to explore the effects of grain boundary stiffness on grain growth. Specifically, we examine how the second derivative of grain boundary energy with respect to inclination influences the interface evolution, grain morphology, and measurable anisotropy in the resulting microstructure. The results show that the inclusion and magnitude of this stiffness contribution can substantially alter grain growth behavior, controlling the degree of anisotropy modeled. These findings demonstrate the importance of correctly incorporating grain boundary stiffness when modeling inclination-dependent anisotropic grain growth in phase-field simulations. |
