Abstract: Recent observations of microstructure evolution during annealing revealed that grain growth not only reduces grain boundary area but also dissipates additional energy through a decrease in average grain boundary energy---a feature that isotropic simulations with uniform energy assumption fail to predict. The authors use a threshold dynamics model incorporating anisotropic grain boundary energies to simulate the observed grain growth of polycrystalline Ni. The model predicts an increase in the relative area of low-energy twin boundaries and a decrease in average boundary energy. This study highlights that realistic simulation of grain growth in polycrystals requires anisotropic grain boundary energy implementation.
