本文综述了用于模拟凝固组织形成过程的定量相场模型的研究进展，重点介绍了该模型的理论基础和研究进展。讨论了在薄界面上再现自由边界问题所需的内插函数的对称性和扩散方程中反捕获电流的必要性。此外，还简要描述了双边非对称扩散相场方程中新的交叉耦合。解释了使用高性能计算技术进行大规模模拟的最新成果。此外，还讨论了定量相场模拟在研究碳钢中的胞晶和枝晶生长、微观偏析和包晶反应等方面的重要应用。
This review presents the development of quantitative phase-field models for simulating the formation processes of solidification microstructures, with particular attention to the theoretical foundation and progress in modeling. The symmetry of interpolating functions required to reproduce the free-boundary problem in the thin-interface limit and the necessity of antitrapping current in the diffusion equation are discussed. In addition, new cross-coupling in the phase-field equation for two-sided asymmetric diffusion is briefly described. Recent achievements of large-scale simulations using high-performance computing techniques are explained. Furthermore, some important applications of quantitative phase-field simulations such as investigations of cellular and dendritic growth, microsegregation, and peritectic reaction in carbon steel are discussed.
