## Description

- description: A thorough understanding and control of the microstructural evolution
    during sintering is essential for improving the properties of various sintered
    materials. In this study, a new multi-phase-field (MPF) model of sintering that
    applies to both solid-state sintering (SSS) and liquid-phase sintering (LPS) in
    multiphase and multicomponent systems was developed. The MPF model incorporates
    the advection term to account for the rigid-body motion (RBM) of the sintered
    particles. Moreover, the MPF model provides thermodynamically reasonable results
    of phase transformation and solute diffusion when coupled with a thermodynamic
    database. The effect of incorporating the RBM was validated by evaluating the
    neck growth and densification rates obtained from the simulation results of SSS.
    The MPF simulation results of the initial stage of LPS demonstrated that the a)
    MPF model could reproduce the densification behavior, which depends on the phase
    transformation between the solid and liquid phases, and b) RBM is an important
    factor in reproducing the densification behavior. A long-term MPF simulation of
    the LPS also demonstrated that the microstructural evolution, including three
    densification-related mechanisms—contact flattening, Ostwald ripening, and solid-state
    bonding—could be analyzed from the initial to final stages of the LPS. This study
    is expected to advance the sintering process applicable to multiphase and multicomponent
    systems.
