## Description

- description: Sintered structures observed in experiments can consist of faceted
    crystal grains. To predict the formation of such structures, a new phase-field
    (PF) model of solid-state sintering that can analyze morphological changes and
    microstructural evolutions considering the strong interface anisotropies of sintered
    particles was developed in this study. The developed PF model treats the crystal
    grain orientation-dependent surface and misorientation-dependent grain boundary
    anisotropies. Furthermore, this model employs quaternions to calculate the particle
    rotation, eliminating complicated calculations involved in analyzing the crystal
    orientation in three-dimensional (3D) simulations. The morphological change in
    a sintered particle and the grain boundary formulation at triple junctions simulated
    using the developed model were validated by comparing them with theoretical solutions.
    The neck growth and densification rates were investigated by performing 3D simulations
    using two particles with interface anisotropies. The simulation results revealed
    that neck growth and densification are affected by surface energy and mobility
    anisotropies. A 3D PF simulation using 200 particles demonstrated that the developed
    PF model can potentially reproduce sintered structures with faceted particles
    observed in experiments. The PF model provides a promising simulation for predicting
    the microstructural evolution of actual materials during solid-state sintering.
