Quantitative phase-field modeling of rapid solidification and its comparison with existing models

Key Points

The aim is to develop a quantitative phase-field model for rapid solidification and compare it with existing models.
Developed a phase-field model incorporating solute trapping and solute drag.
Ensured compliance with solute conservation law at the moving interface.
Accounted for the Gibbs-Thomson effect under thin-interface conditions.
Compared features with the WBM and KKS models to analyze thermodynamic states.
The model accurately reproduces solute conservation laws during solidification.
It effectively incorporates solute trapping and drag effects.
Demonstrated advantages in describing rapid solidification compared to previous models.

Abstract

In this study, we developed a quantitative phase-field model for rapid solidification. The model properly accounts for solute trapping and solute drag, while accurately reproducing the solute conservation law at the moving interface and the Gibbs-Thomson effect in the thin-interface limit. In this presentation, we will particularly discuss how this model incorporates the characteristics of both the WBM and KKS models for description of thermodynamic state. This feature offers an advantage in describing rapid solidification.
