Abstract Scope |
The Critical Materials Institute has developed a multi-pronged approach to finding substitutes for permanent magnets including materials discovery, application of advanced manufacturing methods and substitution at the system level to improve overall motor performance. An integrated computational experimental methodology for materials discovery allows for rapid screening of both intrinsic magnetization properties as well as quickly identifying those systems that can develop extrinsic coercivity . This effort has rapidly identified both high performance magnets with reduced RE content and RE-free magnets that match the performance of existing non-RE magnets or fall in between the performance of RE magnets and non-RE magnets (gap magnets). We will review the search methods employed for identification of new magnet formulations and present predictions for magnets with reduced RE content or RE-free formulations that have potential to substitute for RE magnets or ease the demand for high performance magnets in applications requiring lower performance requirement. |
