Solidification Processing of Binary-Alloy Metal Matrix Composites: A Theoretical and Experimental Analysis

本研究将研究二元合金金属基复合材料凝固过程中发生的质量、动量、热量和物质传递过程。该计划将包括数值和实验两个部分。数值研究将使用单域连续体方法，利用适当的本构关系，包括渗透率模型，来解释流体和糊状区的分散相。结果将通过携带分离纤维的氯化铵水溶液的凝固实验进行验证。流动的可视化，以及温度和速度场的测量将得到。

The study will investigate the mass, momentum, heat, and species transport processes occurring during the solidification processing of binary alloy metal matrix composites. The program will consist of both numerical and experimental components. The numerical study will make use of a single domain continuum approach, making use of appropriate constitutive relations, including permeability models, to account for the dispersed phase in the fluid and in the mushy zone. The results will be verified against solidification experiments with aqueous ammonium-chloride solution carrying isolated fibers. Flow visualization, and measurements of temperature and velocity fields will be obtained.
