Document Type and Number:
WIPO Patent Application WO/2022/190601
Kind Code:
A1
Abstract:
This titanium green compact production method produces a titanium green compact 101 that has a recessed section 102. The recessed section 102 of the titanium green compact 101 has a shape whereby, in at least one cross section that includes at least part of the central axis CC of the recessed section 102, the width changes in at least part of the central axis direction of the recessed section 102 and/or has a shape that includes a curved section and/or a bent section of the central axis Cc of the recessed section 102. The titanium green compact production method includes: a step in which a core material-constituting material is caused to flow into and fill a core material arrangement space 5a that corresponds to the recessed section 102 in a resin mold 1 and a core material 11 that has a shape corresponding to the recessed section 102 is arranged; a step in which a raw material powder is filled in a molding space 2 of the mold 1; and a step in which cold isostatic pressurization is performed at an isostatic pressure of at least 300 MPa on the mold 1 which has the raw material powder filled into the molding space 2, in a state in which the core material 11 is arranged inside the core material arrangement space 5a.
