Comparison of the Advantages Conferred by Mobility and Energy of the Grain Boundary in Inducing Abnormal Grain Growth Using Monte Carlo Simulations

抄録

Advantages conferred by the mobility and energy of the grain boundary in inducing abnormal grain growth (AGG) were compared by three-dimensional Monte Carlo simulations. The percentage of high-mobility or low-energy grain boundaries between the potential grain for AGG and the other grains was varied. The simulation results showed that the minimum percentage of high-mobility grain boundaries required to induce AGG is 50%, whereas that of low-energy grain boundaries needed to induce AGG is 20%.
