To optimize the microstructure of the solid-state materials, such as metals and ceramics, understanding the interaction between the grain boundary and second-phase particle is quite important. The computational approaches including phase-field method, Monte Carlo Potts model or vertex model have been intensively applied to investigate an interaction between grain boundary and second-phase particle, however most of the previous studies were performed for the incoherent interface case. We performed the 3D phase-field modeling to analyze the particle/boundary interaction with the coherent interface. We quantitatively investigated how interface coherency affect the pinning efficiency and grain boundary motion. The obtained results were compared to the analytic theory and experimental observations.
