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

摘要

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 percent age 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 percent age of high-mobility grain boundaries required to induce AGG is 50 percent , whereas that of low-energy grain boundaries needed to induce AGG is 20 percent .
