9417428 Rao描述：该项目支持内华达大学里诺分校化学与冶金工程系Ramana G. Reddy博士和孟买印度理工学院冶金工程系P. Krishna Rao博士之间的合作。本课题涉及原金属加工过程中控制金属间铝化物性能的因素。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）是控制熔体参数从而控制最终产品的一种方法。本课题的重点是研究电熔再熔处理对结构金属间化合物微观组织和拉伸性能的影响。科学家们建议：1。评估、整理和生成金属间铝化物电熔渣的物理化学数据；和2。评估各种现有数学模型的效率和可靠性，必要时开发新的模型来预测助熔剂的物理化学性质。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-性质的相关性。范围：该项目带来了内华达大学里诺分校和印度理工学院孟买分校两个互补的能力，进行基础化学工程研究，目的是了解渣条件和所得到合金性能之间的关系。这项工作可能会为这些关系开发出更好的模型，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，并应该在冶金领域总体上推进科学知识。该项目很好地满足了INT的目标。＊＊＊

9417428 Rao 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. ***
