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.

0129226Zavaliangos 这个为期三年的奖项支持德雷克塞尔大学的 Antonios Zavaliangos 和法国格勒诺布尔国家理工学院的 Didier Bouvard 之间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过程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特征和各向异性方面的建模。 此次合作融合了建模和实验方法。 美国研究人员为此次合作带来了热机械建模方面的专业知识。 参与法国的实验以及法国在理化和微观结构表征方面的专业知识补充了这一点。 粉末混合物的烧结是各种工业过程（例如钢零件和硬磁体的制造）的许多加工技术中的关键步骤。 这项研究将增进我们对粉末混合物行为的理解并增强预测建模能力。 此次合作包括教育部分。 计划有一个教学模块供课堂使用，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 提出的并行提案。 NSF 将为美国调查员和学生提供旅费和生活费。 CNRS 将支持法国研究人员访问美国。
