PURPOSE:To provide a method for manufacturing rare earth magnet powder, in which magnetic characteristics of alloy magnet is improved, mainly composed of R (at least a kind of rare earth element containing yttrium), boron and T (group IIId transition metal element mainly composed of Fe). CONSTITUTION:After the alloy magnet, consisting of 10 to 30atom% R (R is at least a kind of rare earth element containing yttrium), 2 to 28atom% boron and 65 to 82atom% T (T is 3d group transition metal element mainly composed of Fe) has been pulverized mechanically), hydrogen is occluded, dehydrogenated at 200 to 800 deg.C in vacuum, and the rare earth magnet powder is obtained. |
