Incorporating second-phase particles is one of the most efficient way to prevent grain growth during the sintering process. Therefore, it is important to understand the grain boundary/second-phase particle interaction to design the material with the optimal mechanical properties. We investigated a role of the second-phase particle morphology on pinning effect using the phase-field approach. We performed large-scale 3D grain growth simulations with the presence of the various shape of the second-phase particles, such as spherical or cubical/cuboidal particles. We quantitatively measured the pinning effect depending particle orientation as well as particle morphology using the phase-field method. The obtained simulation results were compared with the experimental observation using HRTEM.
