CMI technology Tough Sm-Co won an R&D 100 Award

CMI researchers at Ames Laboratory with industry partner Energy Electron Corporation conducted the research for this highlight

Innovation
CMI developed a mechanically robust, high-performance samarium-cobalt (Sm-Co) magnet with an unprecedented combination of superior mechanical and magnetic properties via a novel heterogeneous microstructure engineering approach. 

Achievements

  • Improves Sm-Co magnet machinability, production rate and service life.
  • Reduces failure rate in production of Sm-Co magnets with complex shapes and sizes and yields up to 40% improved materials utilization. 
  • Survives more demanding service conditions.

Significance and Impact
The technology is compatible with the existing manufacturing process and has been recognized with an R&D100 Award.

Hub Goal Addressed
Win industry adoption of three technologies related to materials substitution for rare earth magnet materials.
