An x-ray pole figure technique was used to study the development of magnetocrystalline texture in the sintering of Nd-Fe-B magnets. The effect of excess Nd on the texture and remanence is emphasized. It is found that a medium content of excess Nd enhances the (006) texture and remanence. However, a high content of excess Nd may deteriorate both texture and remanence, and in addition, the tilt of texture away from the prealigned direction also becomes more significant. It is believed that the floating and rotation of grains on the thick layer of liquid phase during sintering cause the deterioration.
