METHOD OF MAKING PLATE-SHAPED MATERIAL

摘要

A method of making a disc-shaped or plate-shaped sintered body from powdered material of poor ductility, such as Sendust alloy. The powdered material is filled in a dish-like metallic vessel (10) having a thick bottom wall (12) and a low side wall (11). A plurality of such filled vessels are piled up and put in a cylindrical capsule (20) made of hot-workable metal. The capsules charged in a container of a hot extrusion press the outlet of which is closed and it is then heated and compressed. The resultant compressed product is taken out and cooled and metallic parts remaining from the vessels and capsule are removed from the compressed product, thereby obtaining plate-shaped sintered bodies as wanted.
