小行星9313732 描述：该项目支持Ramana G.位于里诺的内华达州大学化学和冶金工程系的Reddy博士和孟买的印度理工学院（IIT）冶金工程系的P. Krishna Rao博士。 本课题涉及的因素控制金属间化合物的性能在加工过程中从原生金属。 高温合金的性能在很大程度上取决于与凝固有关的偏析现象。电渣精炼（ESR）是一种用于控制熔体参数并因此控制最终产品的方法。 本计画的重点是研究电渣重熔工艺对结构金属间化合物显微组织与拉伸性能的影响。 科学家建议：1。 评估、整理和生成金属间铝化物电渣重熔用熔渣的物理化学数据;以及2.评估各种现有数学模型的效率和可靠性，并在必要时开发新的模型来预测焊剂的物理化学性质。 里诺的科学家将致力于数据库的生成和数学模型的开发，而孟买的科学家将处理各种金属间铝化物并研究结构与性能的相关性。 范围：该项目带来了两个互补的能力，在美国。在内华达州、里诺和孟买的IIT进行基础化学工程研究，目的是了解炉渣条件与所得合金性能之间的关系。 这项工作可能会导致为这些关系开发更好的模型，可用于各种材料的设计和加工。 这种合作应该对美国和印度有利，并应该促进冶金领域的科学知识。 该项目很好地满足了INT的目标。 * **

9313732 Reddy Description: This project supports collaboration between Dr. Ramana G. Reddy, Department of Chemical and Metallurgical Engineering at the University of Nevada at Reno, and Dr. P. Krishna Rao, Department of Metallurgical Engineering at the Indian Institute of Technology (IIT) in Bombay. The topic relates to the factors controlling the properties of intermetallic aluminides during processing from the primary metals. The properties of superalloys depend to a large extent on the segregation phenomena associated with solidification. Electroslag refining (ESR) is one method for controlling the parameters of the melt and therefore the final product. The focus of this project is on investigating the effect of ESR processing on the microstructure and tensile properties of structure intermetallics. The scientists propose to: 1. evaluate, collate, and generate the physico chemical data for molten slags for ESR of intermetallic aluminides; and 2. assess the efficiency and reliability of various existing mathematical models and where necessary develop new models to predict the physico chemical properties of fluxes. The scientists at Reno will work on data-base generation, and the development of mathematical models, while scientists at Bombay will process the various intermetallic aluminides and study the structural-property correlation. Scope: This project brings two complementary capabilities, at the U. of Nevada, Reno, and at the IIT, Bombay, to conduct a fundamental chemical engineering study, with the objective of understanding the relationship between the slag conditions and properties of the resulting alloys. The work is likely to lead to developing better models for these relationships that can be used for design and processing of various materials. The collaboration should be beneficial to the U.S. and India and should advance scientific knowledge in the area of metallurgy in general. The project meets INT's objectives well. * **
