Because grain boundaries have a significant influence on the physical properties of polycrystalline solids, their properties, including energy, have been the subjects of extensive experimental and computational study.However, some foundamental problems such as the mobility of grain boundary and the kinetics of grain growth still need some further study.In this paper we report on molecular dynamics simulations of a tricrystal composed of a cylindrical grain embedded at the center of a plane grain boundary and a bicrystal composed of a single grain embedded at the center of a plane grin boundary using the embedded atomic potential and discuss the mobility and kinetics in the process of grain growth.
