Title: Sintering method of rare earth magnet
Inventor: NAWA MASAHIRO
IPC: B22F5/00
Filed: 1985-02-25
Abstract: PURPOSE:To suppress the generation of camber and deformation in the stage of sintering and to prevent the seizure to a base plate, keep plate, etc. in the stage of sintering a thin sheet-shaped green compact molding consisting of rare earth magnet material powder by sintering the green compact molding on many small balls on the base plate. CONSTITUTION:The many small balls 3 are disposed on the base plate 5 and the thin sheet-shaped green compact molding 4 consisting of the rare earth magnet material is imposed thereon; further the small balls 3 are disposed thereon as well and the keep plate 2 is placed thereon. The entire part is put into a Ta foil vessel 6 and a Ta cap 1 is put thereon. The assembly is placed still in an electric furnace and the molding 4 is sintered. Then the seizure arises hardly as the contact area of the molding 4 with the base plate 5 and the keep plate 2 is small in the stage of sintering. Since the small balls 3 have the freedom to move during shrinking of the molding 4, the generation of the nonuniform deformation in the molding 4 is obviated and the camber is effectively suppressed.
