Control of Thermodiffusion in Liquid Multicomponent Alloys

目的：通过数学描述、实验测量和模拟计算，对液态合金的热质量耦合进行综合研究。意义：当液态合金存在于不同温度时，热流和质量流的耦合会导致其组分的快速偏析。这是制造过程中控制液态合金凝固和设计液态合金冷却剂以实现有效传热的一个主要难题。这个问题从未得到解决。预期成果：本研究有望成为本领域的开创性基础。效益：预计本研究将为合理控制液态合金的工程应用提供手段。

Aims: The project aims to comprehensively study heat and mass coupling in liquid alloys by describing it mathematically, measuring it experimentally and calculating it by simulation. Significance: When a liquid alloy exists at different temperatures, the coupling of heat and mass flows causes rapid segregation of its components. This is a major complication in controlling solidification from liquid alloys in manufacturing and in the design of liquid alloy coolants for efficient heat transfer. It has never been addressed. Expected outcomes: This research is expected to be the pioneering foundation of the area. Benefits: It is anticipated that the research would provide the means to properly control the engineering use of liquid alloys.
