CMI researchers from Ames National Laboratory conducted the research for this highlight.
Innovation
Developed a cost-effective manufacturing process for making Nd-Fe-B nanograin magnets, which can function at high temperature without Dy.
Achievement
Created a microstructure engineering solution to address the criticality issue with the heavy rare earth elements.
Significance and Impact
Traditional process for making nanograin Nd-Fe-B magnets is a two-step process requiring expensive tools and vacuum furnaces and has limitations in product size, shape, and productivity. Our novel hot-roll process addresses these by implementing the deformable die concept and making the process semi-continuous.
Hub Target Addressed
Win industry adoption of three technologies related to materials Substitution for rare earth materials.
