Abstract Scope |
Nucleation and growth of the second liquid phase during the solidification of hypomonotectic alloys determine the resulting microstructure. Phase-field modeling, based on principles of thermodynamics and kinetics, is a powerful computational tool for studying microstructure evolution and phase transformations. In this work, we develop a phase-field model for the directional solidification process in hypomonotectic systems. Our focus is on simulating and analyzing droplet entrapment dynamics during the process of directional solidification. A nucleation algorithm is incorporated into a multiphase phase-field model, allowing for the nucleation of the second liquid phase at the solidification front and subsequent entrapment of liquid droplets by the advancing solidification front. By leveraging this phase-field model, we aim to examine the dynamics of liquid droplet entrapment and enhance understanding of the process and its impact on microstructure formation. |
