Abstract

PURPOSE:To obtain a high density rare earth permanent magnet having excellent magnet characteristics by molding powder material adjusted to the specified composition into the specified shape with addition of high speed impact processing and thereafter applying the annealing thereto. CONSTITUTION:On the occasion of manufacturing iron system or cobalt system rare earth magnet, a high speed impact processing 14 employed as a method for raising the density without coarse growth of crystal grain after the integrated processing. The most general method as such processing is the dynamic method which is done using the apparatus shown in the figure. Namely, the powder mixed in the predetermined composition is first pressed with a particular die and is then fixed to a metal die 8 to execute impact processing with the maximum operation gas pressure of about 140kg/cm<2>. Thereafter, heat processing is carried out in the temperature range of 300-1000 deg.C.
