CMI researchers from Ames National Laboratory conducted the activity for this highlight
Innovation
Demonstrated magnet performance competitive with certain NdFeB magnet grades via a novel “hot-roll” semi-continuous fabrication process.
Achievement
Team obtained a hot-rolled magnet with 40.4 MGOe energy product and 11.3 kOe coercivity, along with 100% density.
Significance and Impact
Record-high energy product reveals that a more rigid boundary promotes a higher degree of grain alignment, and thereby greater MH squareness. This principle will guide our future development.
Hub Target Addressed
Accelerated magnet discovery and maturation.
