The bending strength of three groups of samples variously oriented with respect to the length direction of the parent bulk have been measured. The bending macrofractography was carefully observed using SEM. Both the mechanical properties and the fracture behavior of sintered NdFeB permanent magnetic materials were investigated and found to be strongly anisotropic. Intergranular fracture was the primary fracture micromechanism. Cleavage fracture has been clearly observed in the microfractography of the group of bending samples whose orientation was parallel to the length direction, and the bending strength of the corresponding samples was far lower than those of the transverse- oriented samples.
