摘要
相场法是目前微观组织数值模拟领域中最具优势的研究方法,其在凝固微观组织数值模拟方面取得了许多重要研究进展。本文主要综述了近年来多元多相合金凝固微观组织相场法模拟在国内外的研究进展情况,在阐述了多相场模型分类与发展的基础上,对多元合金、多相合金及多元多相合金凝固微观组织相场法模拟的研究进展进行了详细分析,并指出了本研究领域存在的问题及未来的发展方向。
The phase-field method is very powerful in numerical simulation ofmicrostructures. Great progress has been achieved by using phase-field method in numerical simulation of solidification microstructures. In this paper, progress in phase-field simulation of solidification microstructures of multi-component multi-phase alloys in recent years is reviewed. Based on the introduction of multi-phase-field models, the progress in phase-field simulation of solidification microstructures is discussed in details from three aspects： multi-component alloys, multi-phase alloys and multi-component multi-phase alloys. The existing problems and development trends in this field are also pointed out.
