METHOD OF MAKING PLATE-SHAPED MATERIAL

摘要

Disclosed is a method of making a disc-shaped or plateshaped sintered body from powdered material of poor ductility, such as Sendust alloy. The powdered material is filled in a dishlike metallic vessel having a thick bottom wall and a low side wall. A plurality of such filled vessels are piled up and put in a cylindrical capsule made of hot-workable metal. The capsule is charged in a hot press and is then heated and compressed. The resultant compressed product was taken out and cooled and the vessels and the capsule are removed, thereby obtaining the desired plate-shaped sintered bodies. According to the method, the sintered body having a uniform thickness and substantially no pores can be obtained.
