CMI researchers at Ames National Laboratory conducted the research for this highlight.
Innovation
Produced an M-grade nanograin NdFeB magnet achieving 44.2 MGOe (BH)max using our novel hot-roll fabrication process.
Achievement
10% BHmax increase beyond Yr-12 record. Matches the performance of today’s most-sold nanograin magnets made by the conventional hot-press/hot-deformation route.
Significance and Impact
- Validates our hypothesis on the effect of rigid mechanical boundary condition on density and texture.
- Improved properties put effort within striking distance of large market demand N45SH thin magnet.
Hub Goal Addressed
Microstructural engineering to reduce the need for dysprosium.
