Document Type and Number:
WIPO Patent Application WO/2023/181654
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a titanium alloy material that makes it possible to form a titanium alloy component that has excellent high-temperature durability, even when strain has been applied during processing. According to one aspect of the present invention, a titanium alloy material includes 0.2–0.5 mass% of Al and 0.3–0.6 mass% of Si and has an Mo equivalent [Mo]eq as represented by expression 1 of at least 0.35, the remainder being Ti and unavoidable impurities. 1: [Mo]eq=[Mo]+[Ta]/5+[Nb]/3.6+[W]/2.5+[V]/1.5+1.25[Cr]+1.25[Ni]+1.7[Mn]+1.7[Co]+2.5[Fe] ([X] being the X element content (mass%) of the titanium alloy material).
