摘要:High anisotropic Nd13Fe75Co4B8 magnetic powders are obtained with low desorption Hz-pressure of the hydrogenation disproportionation desorption recombination (HDDR) process. Scanning electron microscopy (SEM) indicates a lamella structure in the 20 kPa desorption Hz-pressure HDDR products and may be related to the high anisotropy. The magnetic powders with a desorption Hz-pressure of 20 kPa have the magnetic properties of Br=0.86 T and Mr/Ms=0.81. This shows that the Hz-pressure has great effect on the formation of crystal texture in the HDDR Nd-Fe-B powders.
