G8 Initiative: High Performance permanent Magnets Sustainable for Next Generation

美国国家科学基金会授予阿拉巴马大学塔斯卡卢萨分校和特拉华大学的奖项，资助美国研究人员参加由八国集团研究理事会倡议的“材料效率跨学科计划-迈向可持续制造的第一步”项目的竞争。这是美国国家科学基金会、加拿大国家科学与工程研究委员会（NSERC）、法国国家研究局（ANR）、德国德国科学促进会（DFG）、日本科学促进会（JSPS）、俄罗斯基础研究基金会（RFBR）和英国研究委员会（RCUK）之间的试点合作。支持在竞争基础上选出的由至少三个伙伴国家的研究人员组成的合作研究项目。这个与美国、德国和日本合作的跨学科项目重点关注永磁体（PM）材料稀缺和高成本的问题，并为这些问题提供替代解决方案。目前高性能永磁材料在很大程度上依赖于稀土元素。该联盟的目标是开发无re的PM。重点研究PM的薄膜和纳米颗粒，以（BH） max约为25 MGOe为第一步。这种永磁体有可能使磁性MEMS和生物医学传感器等新应用成为可能。在第二阶段，重点将放在从薄膜和纳米颗粒到粉末和块状永磁体的发展上。此外，生产和回收材料的制造工艺的发展将在非资助行业专家的帮助下整合。目标是建立知识，以实现（BH） max，可与钕铁硼相媲美。该联盟由来自三个国家的六个组织组成。所有合作伙伴成员都有丰富的永磁体经验，包括拟议的锰合金体系。该联盟将从基本材料问题、加工和制造以及成本效益的角度研究无RE PM。重点培养学生和博士后。

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.
