项目摘要

0129226ZavaliangosThis three-year award supports US-France collaboration in metal and ceramic powder manufacturing between Antonios Zavaliangos of Drexel University and Didier Bouvard of the National Polytechnic Institute, Grenoble, France. Their collaboration addresses modeling and experimental aspects of anisotoropic shrinkage in sintering and compaction powder processes. During these processes, powder mixtures are pressed into different and sometimes complex forms. Characterization of microstructure evolution during powder sintering and modeling of anisotropic aspects will be studied. The collaboration merges modeling and experimental approaches. The US investigator brings to this collaboration, expertise in thermomechanical modeling. This is complemented by participation in experiments in France and French expertise in physiochemical and microstructural characterization. Sintering of powder mixtures is a key step in a number of processing techniques for a variety of industrial processes, such as manufacturing of steel parts and hard magnets. This research will advance our understanding of behavior of powder mixtures and enhance predictive modeling capabilities. The collaboration includes an educational component. An instructional module is planned for classroom use and undergraduate students will participate in the experiments in France. This award represents the US side of parallel proposals to the NSF and the CNRS. NSF will cover travel funds and living expenses for the US investigator and students. The CNRS will support visits by French researchers to the United States.

0129226Zavaliangosthis三年奖奖支持德雷克塞尔大学的安东尼奥斯·扎瓦利安戈斯（Antonios Zavaliangos）与法国格伦布尔国家理工学院国家理工学院的Antonios Zavaliangos之间的金属和陶瓷粉制造合作。他们的协作介绍了烧结和压实粉末过程中各种剖面收缩的建模和实验方面。在这些过程中，将粉末混合物压成不同的，有时甚至是复杂的形式。将研究粉末烧结过程中微观结构演变的表征和各向异性方面的建模。协作合并建模和实验方法。美国调查员带来了这种合作，热力学建模方面的专业知识。参与法国的实验以及法国的生理化学和微结构表征方面的专业知识，这是补充的。粉末混合物的烧结是多种工业过程（例如钢零件制造和硬磁铁制造）的多种加工技术的关键步骤。这项研究将提高我们对粉末混合物行为的理解，并增强预测性建模能力。该协作包括一个教育组成部分。计划提供教学模块供课堂使用，本科生将参加法国的实验。该奖项代表了NSF和CNR的平行建议的美国。 NSF将为美国调查员和学生提供旅行资金和生活费用。中枢神经系统将支持法国研究人员对美国的访问。
