The proposed NSF IRES program will provide support for 19 students pursuing research in materials science and engineering. These students will engage in collaborative international research with the IMDEA Materials Institute (IMDEA) in Madrid, Spain. Each year, 7 students will spend 7 weeks performing research on grain boundary formation and evolution during processing and its effects on the properties of hexagonal and body centered cubic (BCC) alloys. The IMDEA mentors are world leaders in physical and mechanical metallurgy, and modeling of advanced alloys, and the program focuses on the development of hexagonal magnesium alloys, which are targeted for application in the transportation and biomedical industries. The participating IRES students will gain experience with advanced computational and experimental methods, present their research in an international setting, write reports and manuscripts for publication in scientific journals, and build professional and personal networks in Spain with scientists from all over the world. Given the prominence of IMDEA in Spanish science and its interactions with industry, IMDEA is uniquely-positioned to provide students with new perspectives to prepare them for a variety of future careers in which collaborations with European agencies are desirable. Building on their experiences at MSU, this program will expose students to a different approach to research as well as to everyday life in a different culture. Walking tours in Madrid and excursions to nearby cities will be included in the program along with other cultural activities supervised by the IMDEA mentors. The broader impacts of the program will extend beyond the number of participating students and will include the following: This program is part of a larger push to make education abroad opportunities an integral part of undergraduate and graduate education at Michigan State University (MSU) offering a pipeline for future research-intensive educational abroad opportunities that are currently lacking. The experiences and collaborations the participating students bring back to MSU will enhance the development of an international, diverse, and inclusive culture at MSU, which is a high priority within the MSU College of Engineering and the greater university. The students will work on innovative projects that involve advanced concepts in solidification experiments and modeling, in-situ microstructural characterization techniques, deformation and its modeling, and processing-microstructure-property relationships. The unifying theme of these projects is characterizing and modeling grain boundaries. The projects are tied together by a rigorous structure- and mechanism-based approach whereby students examine hypotheses using advanced experimental and computational tools. The students’ contributions will bring new insights to designing hexagonal and BCC metals for targeted properties and applications. The intellectual merit of the proposed work lies in understanding processing-microstructure-property relations of hexagonal and BCC alloys to help produce polycrystalline microstructures with a balance of properties that are attractive for industrial applications.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

拟议的NSF IRES计划将为19名从事材料科学和工程研究的学生提供支持。这些学生将与西班牙马德里的IMDEA材料研究所（IMDEA）进行合作国际研究。每年，有7周的学生将花费7周的时间对处理过程中的晶界形成和进化进行研究及其对六角形和身体中心立方（BCC）合金的特性的影响。 IMDEA导师是世界和机械冶金学领域的领导者，并且对高级合金进行建模，该计划的重点是六边形镁合金的开发，六边形镁合金是针对运输和生物医学工业的应用。参与的IRES学生将获得先进的计算和实验方法的经验，在国际环境中介绍他们的研究，在科学期刊上撰写报告和手稿，并与来自世界各地的科学家在西班牙建立专业和个人网络。鉴于IMDEA在西班牙科学中的突出及其与行业的互动，IMDEA具有独特的位置，可以为学生提供新的观点，以准备他们为各种未来职业做好准备，在这些职业中，与欧洲机构的合作是值得期望的。在他们在MSU的经验的基础上，该计划将使学生采取不同的研究方法以及不同文化中的日常生活。该计划将包括在马德里的徒步旅行，前往城市附近城市的游览将包括在IMDEA导师监督的其他文化活动中。该计划的更广泛影响将超出参与学生的数量，其中包括以下内容：该计划是密歇根州立大学（MSU）的本科和研究生教育不可或缺的一部分，为未来的研究强化教育机会提供了目前缺乏的未来研究密集的教育机会的一部分。参与的学生带回MSU的经验和合作将增强MSU的国际，潜水和包容性文化的发展，MSU是MSU工程学院和大型大学中的重中之重。学生将研究涉及凝固实验和建模，原位微观结构特征技术，变形及其建模以及处理 - 微观结构 - 培训关系的创新项目。这些项目的统一主题是表征和建模晶粒边界。这些项目通过严格的基于结构和机制的方法将其捆绑在一起，学生们使用先进的实验和计算工具检查假设。学生的贡献将为设计目标和应用程序设计六角形和BCC金属带来新的见解。 The intellectual merit of the proposed work lies in understanding processing-microstructure-property relations of hexagonal and BCC alloys to help produce polycrystalline microstructures with a balance of properties that are attractive for industrial applications.This award reflects NSF's statutory mission and has been deemed precious of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
