Bulk, Exchange-Coupled Nitride Magnets
Agency / Branch:
DOD / ARMY
The objective of this proposal is to demonstrate the feasibility of producing exchange-coupled magnets with a mixture of Sm2Fe17Nx and alpha double prime-iron nitride powders as starting materials. Advanced Materials Corporation (AMC), together with Georgia Institute of Technology propose to produce these powders with the use of a fluidized bed reactor and consolidate mixtures of these powders utilizing shock compaction techniques to produce exchange coupled magnets. During Phase I, AMC will examine a number of experimental variables (such as relative concentraions of the two nitrides, pressures of compaction and temperatures of consolidation to produce isostropic permanent magnets. The goal in Phase I is to demonstrate overall feasibility for manufacturing nitrided magnets. During Phase II, AMC and Georgia Tech will undertake the feasibility of producing anisotropic exchange coupled magnets.
