CMI researchers from Ames National Laboratory and Purdue University conducted the activity for this highlight
Innovation
A novel continuous hot-roll deformation process was assessed for cost-effective manufacturing of nanograin NdFeB magnets.
Achievement
- The hot-roll process streamlines NdFeB magnet production.
- Eliminates dysprosium while maintaining high-temperature performance.
- Nearly waste-free vs 15-25% waste in traditional methods.
- Positive profit compared to losses for conventional approaches.
Significance and Impact
The new method reduces costs and risks while enhancing efficiency in magnet production for clean energy applications. This work demonstrated a successful intrahub collaboration and supported student growth and engagement with the international research community.
