摘要：PURPOSE:To provide a method of obtaining high-molecular composite rare earth magnet alloy powder excellent in characteristics. CONSTITUTION:A parent alloy ingot is repeatedly subjected to a process wherein it is thermally treated in an atmosphere of hydrogen to occlude hydrogen and then thermally treated in a vacuum again to forcibly remove hydrogen or repeatedly subjected to the above process carried out in a magnetic field of certain direction, whereby rare earth magnet alloy powder high in magnetic characteristics can be obtained.
