小行星9623599 这个职业计划的重点是研究与金属间化合物加入到传统的镍基高温合金密切相关的教育活动。瞬时液相（TLP）连接作为一种技术，用于连接结构金属间化合物，因为它是有限的低温延展性和稳定的氧化物形成的容忍往往表现出这样的合金系统。 该研究旨在阐明镍铝合金/高温合金接头中控制加工结构性能关系的机制，从而展示改进微观结构控制的途径。 制定合适的过程建模工具是研究的重要组成部分。学生经常遇到的一个困难是在科学的不同方面之间建立共享和关联概念的相互联系。该计划的教育部分开发了一个关于金属间合金到高温合金连接的教育模块，该模块说明了材料科学的关键方面，并适当强调微观结构发展，材料加工，机械性能，动力学和热力学。 本单元将包括多媒体教学资源和课堂演示。 金属间化合物领域构成了美国和世界范围内的主要研究活动。 初始制造和维修后需要适当的方法。 金属间化合物与常规材料（例如超合金）的接合是特别重要的，因为金属间化合物可能在主要由这种材料组成的工程系统内局部使用。 ***

9623599 Gale This CAREER program focuses on research with closely linked educational activities related to joining of intermetallic compounds to conventional nickel-base superalloys. Transient liquid phase (TLP) bonding is examined as a technique for bonding structural intermetallics since it is tolerant of limited low temperature ductility and stable oxide formation often exhibited by such alloy systems. The research aims to elucidate the mechanisms controlling processing structure property relationships in nickel aluminide/superalloy joints and thereby demonstrate routes for improved microstructural control. The formulation of suitable process modeling tools are a vital part of the research. A difficulty often encountered by students is establishing interconnections in terms of shared and linked concepts between different aspects of science. The educational part of the program develops an educational module on intermetallic alloy to superalloy joining that illustrates key aspects of materials science with appropriate emphasis on microstructural development, materials processing, mechanical properties, kinetics and thermodynamics. This module will include multimedia teaching resources and inclass demonstrations. %%% The field of intermetallic compounds constitutes a major research activity both within the US and worldwide. Suitable methodologies are needed for initial fabrication and post service repair. The joining of intermetallics to conventional materials, such as superalloys, is particularly important as intermetallics are likely to be used locally within engineering systems composed predominantly of such materials. ***
