Nd-Fe-B type permanent magnets are produced by the powder metallurgical process. Therefore, the rough milling methods of making a coarse powder of the Nd-Fe-B alloy are of importance. In these methods, the characteristics of powders, i.e. shapes of powder, particle size distributions, oxygen content and chemical compositions, play a very important role on magnetic properties and manufacturing process of Nd-Fe-B sintered magnets. In order to clear these unknown problems, the Hydrogen Decrepitation (HD) method, which is one of the rough milling techniques, was especially employed. In this paper, the influences of both the hydrogen absorbing conditions and the alloy making conditions on the hydrogen absorbing behaviors in Nd-Fe-B alloy have been investigated using P -C-Tequipment. And the fundamental mechanism of hydrogen absorption into different phases of N d-Fe-B alloy was revealed.
