CMI researchers at Ames Laboratory conducted the research for this highlight
Attained BHmax of 5.9 MGOe (pressed pellet) and 2.5 kOe coercivity (powder) via innovative yet simple, scalable, mechanochemical process (MP), while achieving reproducible 98+% yields of precursor t-FeNiN.
Significance and impact
High-performance, rare earth-free, low-cost material with the potential to quickly and broadly penetrate PM markets.
- Beneficiation (Fe/Ni ratio; doping with 1-2 at.% of transition; further refinements of microstructure)
- Scale-up to 1-10 g quantities of L10-FeNi
- IP disclosure drafted, under revision
- Fabrication of magnets (grain alignment and compaction)
