The study of magnetic properties, coercivity mechanism and bending strength of hot-deformed RE-Fe-B magnets.

The effect on mechanical properties and magnetic properties of hot-deformed magnets with different rare earth (RE) content has been investigated. The results show that the optimal comprehensive magnetic properties are obtained at 13.09 at% RE. The bending strength parallel to c -axis orientation increases with the increasing of RE content, while that perpendicular to c -axis orientation exhibits decrease. Moreover, the micro magnetic structure was observed and the coercivity mechanism of the hot-deformed magnet sample was discussed. [ABSTRACT FROM AUTHOR]
