摘要
金属凝固微观组织对金属的性能有着决定性的影响,利用相场方法模拟凝固微观组织形成和演化已在国内外取得成功。介绍相场方法的基本原理,综述近年来国内外在这一领域的研究进展,重点介绍相场方法在枝晶生长方面的应用,并指出了进一步的发展方向。
Solidification microstructures play a critical role in the performance of metallic materials. By using phase-field method,great success has been achieved on the simulation of formation and evolution of solidification microstructures. In this paper,the basic principles of phase-field method are introduced and the recent advances in this field,especially the simulation of dendrite growth,are reviewed. The future directions are also suggested.
