## Description

- description: Solute segregation significantly affects material properties and is
    a critical issue in the laser powder-bed fusion (LPBF) additive manufacturing
    (AM) of Ni-based superalloys. In this study, we demonstrated a computational thermal-fluid
    dynamics (CtFD) simulation coupled multi-phase-field (MPF) simulation with a multicomponent-composition
    model of Ni-based superalloy to predict solute segregation under solidification
    conditions in LPBF. Solute segregation at the various interfacial regions of Ni-based
    multicomponent alloys could be predicted by the conventional MPF simulation. The
    design of crack-free Ni-based superalloys can be expedited by MPF simulations
    of a broad range of element combinations and their concentrations in multicomponent
    Ni-based superalloys.
