摘要:Anisotropic Pr12.5Fe72.5Co6Cr2B7 magnetic powders are obtained by varying the desorption H-2-pressure of the hydrogenation disproportionation desorption recombination (HDDR) process. The magnetic powders with a desorption H-2-pressure of 30 kPa have the magnetic properties of Br=0.96 T, H-i(c)=8.2 kOe and B-r/B-s =0.78, whereas the magnetic powders obtained with a higher and a lower desorption H-2-pressure are isotropic. A distinct lamella crystal is observed in the 30 kPa desorption H-2-pressure products and may be related to the anisotropy in the HDDR-treated powders. It is believed that the desorption H-2-pressure has great effect on the formation of crystal texture in the HDDR Pr-Fe-B powders.
