Abstract
Interaction between a grain boundary and deformable particles has been modeled. It is shown that deformable particles pin the grain boundaries more effectively than rigid spherical particles. The required driving force to unpin a grain boundary increases with decreasing the interphase energy of the deformable particle. Deformable particles also reduce the rate of grain-boundary migration more effectively than rigid spherical particles. The rate of grain boundary migration decreases with the interphase energy of the deformable particle. The model allows the shape of a deformable particle to be determined as the particle is dragged by a grain boundary. The particle shape allows prediction of the force acting on the particle.
