GREEN COMPACT AND POWDER COMPACTION PROCESS, METALLIC SINTERED BODY AND ITS MANUFACTURING METHOD, AND WORKED COMPONENT PART AND METHOD OF WORKING

摘要

PROBLEM TO BE SOLVED: To provide a powder compaction process by which active metal powder can be compacted under high pressure.;SOLUTION: The powder compaction process comprises the steps of: applying a higher fatty acid-based lubricant to the inner surface of a die; filling a raw material powder whose major component is an active metallic element into the die after the application step; compacting the raw material powder after the filling step by warm pressing to make a green compact; and ejecting the green compact after the compaction step from the die. The resultant green compact has high density. By this procedure, the active metal powder composed of the active metallic elements, such as Ti and Al, can be pressed under high pressure without causing galling etc. at the inner surface of the die, and the green compact having high density which has not been available conventionally can be obtained.;COPYRIGHT: (C)2004,JPO
