摘要
介绍了相场方法的两种基本原理,阐述了相场方法在金属凝固过程微观组织形成模拟中的应用情况。指出了相场方法非常适合于微观组织三维模拟,用其他方法则存在较大难度。以后进一步研究的重点方向是更优的数值算法、更精确的数值模型、三维定量模拟以及实用化研究。
Two principles of the phase field method are introduced, and the application of the phase field method for numerical simulation of solidification microstructure is expatiated. It is pointed out that the phase field method is very suitable to compute the 3D microstructure than other methods. The directions of further research on the phase field method are aimed at better numerical arithmetic, more precise model, 3D quantitative simulation and utility.
