チタン合金及びその製造方法
Document Type and Number:
Japanese Patent JP7087861
Kind Code:
B2
Abstract:
To provide a titanium alloy having excellent corrosion resistance by suppressing local corrosion of an intermetallic compound or a β phase neighbor, and a manufacturing method therefor.SOLUTION: There is provided a titanium alloy containing, by mass%, Fe:0.010 to 0.300%, Ru:0.010 to 0.15%, Cr:0 to 0.10%, Ni:0 to 0.30%, Mo:0 to 0.10%, Pt:0 to 0.10%, Pd:0 to 0.20%, Ir:0 to 0.10%, Os:0 to 0.10%, Rh:0 to 0.10%, and the balance Ti with impurities, and having an A value of the following formula (1) representing a component ratio of an element contained in a β phase crystal particle in a range of 0.550 to 2.000. A=([Fe]+[Cr]+[Ni]+[Mo])/([Pt]+[Pd]+[Ru]+[Ir]+[Os]+[Rh]) (1), wherein a display [element symbol] represents element concentration (mass%) in the β phase crystal particle.SELECTED DRAWING: None
