In this study, a novel formulation of phase field model for representing solidification of polycrystalline metals is proposed. A quaternion-based crystal orientation representation is introduced into the KWC-type phase field model. Using this approach, three-dimensional rotation of crystal orientation can be represented by a direct extension of the conventional KWC model. A numerical simulation by the presented model is conducted, and the characteristics and adequacy of the model are discussed.
