Method and machine of making rare-earth alloy granulated powder and method of making rare-earth alloy sintered body |
摘要 |
A method of making a rare-earth alloy granulated powder according to the present invention includes the steps of: preparing a rare-earth alloy powder; generating remnant magnetization in the powder; and granulating the powder by utilizing agglomeration force produced by the remnant magnetization of the powder. Since the agglomeration force produced by the remnant magnetization is utilized, the addition of a granulating agent may be omitted.
