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.

0129226 Zavaliangos这个为期三年的奖项支持德雷塞尔大学的Antonios Zavaliangos和法国格勒诺布尔国家理工学院的Didier布瓦尔在金属和陶瓷粉末制造方面的美法合作。他们的合作解决了烧结和压实粉末工艺中各向异性收缩的建模和实验方面的问题。在这些过程中，粉末混合物被压制成不同的，有时是复杂的形式。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。该合作融合了建模和实验方法。美国研究人员为这次合作带来了热机械建模方面的专业知识。此外，还参加了在法国进行的实验，并获得了法国在物理化学和微观结构表征方面的专门知识。粉末混合物的烧结是用于各种工业过程的许多加工技术中的关键步骤，例如钢部件和硬磁体的制造。这项研究将促进我们对粉末混合物行为的理解，并提高预测建模能力。合作包括教育部分。一个教学模块计划用于课堂使用和本科生将参加在法国的实验。该奖项代表了美国方面向NSF和CNRS提出的平行建议。 NSF将支付美国研究人员和学生的旅费和生活费。 CNRS将支持法国研究人员访问美国。
