CMI researchers at Oak Ridge National Laboratory and Ames Laboratory conducted the activity for this highlight
Alloys based on Ce2Fe14B may offer energy products at or exceeding 30 MG-Oe at greatly reduced cost and criticality relative to Nd2Fe14B.
First principles calculations and associated experimental work find a series of inexpensive alloys with potential as strong permanent magnets
Significance and Impact
Alloys may become new low-cost permanent magnets and ultimately substitute for some of NdFeB market
Hub Target Addressed
Win industry adoption of three technologies related to materials substitution for rare-earth magnet materials
