CMI researchers at Ames Laboratory conducted the research for this highlight
A novel bulk magnet fabrication process has been developed. Using hot-rolling processing, a thin bulk magnet with 37 MGOe at RT has been achieved, a significant improvement from 33 MGOe results reported six months ago.
Significance and impact
This manufacturing method was specifically developed for making small magnets: (1) simplified processing steps reduces the cost; (2) innovative use of copper deformable die enhance corrosion and magnetic properties; (3) the near-net-shape cross-section reduce part-failure rate and rare earth waste.
- Design new composition to enhance texture.
- Scale-up for semi-continuous process
