Abstract
The microstructure-magnetic property relationships of the (Nd, Dy)-(Fe, Co)-B sintered magnets with both (Al, Cr) and (Al,
Cr, Nb) additions were examined. A new NdFeNbB-phase has been observed in Nb-containing magnet. Small Nb additions increase
coercivity and improve elevated temperature magnetic properties.
