中文摘要
本文采用数值分析和实验验证相结合的方法,研究了对流对金属枝晶凝固过程中晶粒组织发展和合金元素分布的影响。将建立一个数值模型,并将其预测结果与透明合金和金属合金凝固过程中的高分辨率随时间变化的实验测量结果进行比较。这项工作将潜在地指出铸造技术的改进。
英文摘要
ABSTRACT Cristoph Beckerman University of Iowa CTS-9501389 This work is a combined numerical analysis with experimental validation of the effects of convection on grain structure development and the distribution of alloying elements during dendritic solidification of metals. A numerical model will be developed and its predictions compared with high resolution time-dependent experimental measurements during the solidification of transparent and metallic alloys. The work will potentially point out improvements in casting technology.
