Development of novel Fe-based permanent magnets for high temperature applications

该项目是与加拿大通用汽车公司合作的。它旨在识别、表征和开发用于高温应用的低成本铁基永磁体。这种磁铁是汽车工业所需要的，主要用于电动马达以及其他汽车零部件。这项研究还将使航空、电机生产、电子设备和风能等广泛的行业受益。永久磁铁也是国防活动中使用的部件所必需的。在一定程度上满足当前技术要求的磁体含有大量昂贵的稀土元素。更重要的是，目前这些稀土金属的供应几乎完全依赖外国来源。在这个项目中，这些金属的使用量将降至最低，昂贵的稀土(Nd、Dy和Sm)将被更丰富、更便宜的元素(如Ce)取代。

This project is in collaboration with General Motors of Canada. It aims at identifying, characterizing and developing low-cost Fe-based permanent magnets for high temperature applications. Such magnets are needed for the automotive industry, mainly for the electric motors in addition to other automobile parts. This research will also benefit a wide range of industries such as aeronautical, motor production, electronic equipment and wind energy. Permanent magnets are also necessary for components used in national defense activities. The magnets that satisfy to some extent the current technological demands contain significant amounts of expensive rare earth elements. More importantly, currently there is almost complete dependence on foreign sources to supply these rare earth metals. In this project, the use of these metals will be minimized and the expensive rare earths (Nd, Dy and Sm) will be replaced with a more abundant and less expensive element such as Ce.
