IRES Track I: Characterization and Modeling of Grain Boundaries in Hexagonal and Body Centered Cubic Alloys: Linking Processing and Properties

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。这些学生将与位于西班牙马德里的IMDEA材料研究所(IMDEA)进行国际合作研究。每年，7名学生将花7周时间研究加工过程中晶界的形成和演变及其对六方和体心立方(BCC)合金性能的影响。IMDEA的导师是物理和机械冶金以及先进合金建模方面的世界领先者，该项目专注于六方镁合金的开发，目标是在交通和生物医学行业中应用。参与IRES的学生将获得先进的计算和实验方法的经验，在国际背景下展示他们的研究，撰写报告和手稿发表在科学期刊上，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地位及其与工业的互动，IMDEA具有独特的地位，可以为学生提供新的视角，为他们未来的各种职业做准备，在这些职业中，与欧洲机构的合作是可取的。基于他们在密歇根州立大学的经验，这个项目将使学生接触到不同的研究方法以及不同文化中的日常生活。在马德里的徒步旅行和附近城市的短途旅行将与IMDEA导师监督的其他文化活动一起包括在该项目中。该计划的更广泛影响将超越参与学生的数量，并将包括以下内容：该计划是使海外教育机会成为密歇根州立大学(MSU)本科生和研究生教育不可或缺的一部分的更大努力的一部分，为未来目前缺乏的研究密集型海外教育机会提供渠道。参赛学生带回密歇根州立大学的经验和合作将促进密歇根州立大学发展国际化、多元化和包容性的文化，这是密歇根州立大学工程学院和更大的大学的高度优先事项。学生将致力于创新的项目，涉及凝固实验和建模中的先进概念，原位微结构表征技术，变形及其建模，以及工艺-组织-性能关系。这些项目的统一主题是描述和模拟颗粒边界。这些项目通过一种严格的基于结构和机制的方法联系在一起，学生使用先进的实验和计算工具检查假设。这些学生的贡献将为设计具有针对性的性能和应用的六角形和体心立方金属带来新的见解。拟议工作的智力价值在于了解六方和体心立方合金的加工-组织-性能关系，以帮助生产具有工业应用吸引力的性能平衡的多晶微结构。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
