Title:
TITANIUM ALLOY POWDER PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/157156
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a titanium alloy powder production method whereby the yield of titanium alloy powder is improved while allowing the environmental burden to be reduced. The titanium alloy powder production method according to the present invention comprises a first melting step, an ingot producing step, a second melting step, and a powdering step. In the first melting step, a molded body obtained by compressing a mixed powder containing a titanium powder and a powder of a metal element other than titanium is melted to prepare a first molten metal. In the ingot producing step, the first molten metal is injected into a mold, and the first molten metal solidifies to produce an ingot. In the second melting step, the ingot is melted in an inert gas atmosphere to prepare a second molten metal. In the powdering step, the second molten metal is powdered by a gas atomizing device.
