Microstructure dictates the characteristics of the sintered material and its usability in different applications. Understanding the mechanisms behind the morphological changes during sintering enables optimizing the process for desired outcomes. We present a phase field based multi-physics model to capture the microstructure evolution during the sintering process emphasizing on the role of direction dependent mobility and grain orientation. Unique feature of the current model includes implementation of the possibility of particle’s orientation change during the process due to rigid body motion. Consideration of anisotropic mobility captures the effect of different diffusion coefficients such as surface and grain boundary diffusion along with their direction and grain orientation helps in accurately capturing the shape change and deformation behavior of the particles during the sintering process. Overall, inclusion of anisotropic behavior bridges the gap between the computational model prediction and actual physical behavior.
