G8 Initiative: High Performance Permanent Magnets sustainable for Next Generation (HPPMSNG)

该NSF奖授予阿拉巴马大学塔斯卡卢萨分校和特拉华大学，资助参与G8研究理事会倡议竞争性选择的一个项目的美国研究人员：材料效率跨学科计划：迈向可持续制造的第一步。这是美国国家科学基金会、加拿大国家科学与工程研究理事会(NSERC)、法国国家科学与工程研究理事会(ANR)、德国联邦科学促进会(DFG)、日本科学促进会(JSPS)、俄罗斯基础研究基金会(RFBR)和英国研究理事会(RCUK)之间的试点合作，支持在竞争基础上选出的由至少三个合作伙伴国家的研究人员组成的合作研究项目。这一与美国、德国和日本合作的跨学科项目重点关注永磁体(PM)中稀缺的可获得性和高成本材料的问题，并为这些问题提供替代解决方案。目前的高性能粉末冶金对稀土元素的依赖程度很高。该联盟旨在开发无稀土粉末冶金重点放在(BH)max约为25MGOe的PM的薄膜和纳米颗粒上。这种永磁体有可能实现新的应用，如磁性MEMS和生物医学传感器。在第二阶段，重点将是从薄膜和纳米粒子到粉末和块体永磁体的发展。此外，将在一名非资助的行业专家的帮助下，整合生产和回收材料的制造工艺的开发。其目标是建立可与NdFeB相媲美的知识以实现(BH)max。该联盟由来自三个国家的六个组织组成。所有伙伴成员都在永磁体方面有丰富的经验，包括建议的锰合金系统。该联盟将从基础材料问题、加工和制造以及成本效益的角度研究无稀土粉末冶金。此外，还将重点培养学生和博士后研究员。

This NSF award to the University of Alabama Tuscaloosa and the University of Delaware funds U.S. researchers participating in a project competitively selected by the G8 Research Councils Initiative "Interdisciplinary Program on Material Efficiency: A first step towards sustainable manufacturing." This is a pilot collaboration among the U.S. National Science Foundation, the Canadian National Sciences and Engineering Research Council (NSERC), the French Agence Nationale de la Recherche (ANR), the German Deutsche Forschungsgemeinschaft (DFG), the Japan Society for the Promotion of Science (JSPS), the Russian Foundation for Basic Research (RFBR),and the United Kingdom Research Councils (RCUK), supporting collaborative research projects selected on a competitive basis that are comprised of researchers from at least three of the partner countries. This interdisciplinary project with the United States, Germany and Japan focuses the issues of scarce availability and high-cost materials in Permanent Magnets (PM) and to offer alternative solutions for these issues. The current high performance PM heavily depend on Rare-Earth elements (RE). The consortium aims to develop RE-free PM. Emphasis focuses on thin films and nano-particles of PM with (BH) max of about 25 MGOe as the first step. Such Permanent Magnets have the potential to make possible new applications such as magnetic MEMS and biomedical sensors. At the second stage, emphasis will be placed on the development from thin films and nanoparticles to powders and bulk Permanent Magnets. Also, the development of fabrication processes for production and recycling of the materials will be integrated with the aid of a non-funded industry expert. The goal is to build the knowledge to achieve (BH) max, comparable to that for NdFeB.The consortium consists of six organizations from three countries. All the partner members have had rich experience on Permanent Magnets including the proposed Mn alloy systems. The consortium will work on RE free PM from fundamental materials issues, processing and manufacturing, and cost-effectiveness points of view. Also, emphasis will be placed on training students and post-doctoral fellows.
