Ti alloy and Ti alloy member having Zr and Hf, or Zr and Nb, or Zr, Hf, and Nb for hydrogen embrittlement resistance
View Patent ↗Disclosed are a Ti alloy having an excellent hydrogen absorption inhibition effect, a Ti alloy member using the Ti alloy, and a manufacturing thereof. A Ti alloy is characterized in that it contains 0.1 to 5.0% by mass in total of at least one of Zr and Hf, and a residue comprising Ti and impurities.
1. A Ti alloy having resistance to hydrogen embrittlement consisting of Zr, Hf, and a residue consisting of Ti and impurities, in which the total content of Zr and Hf is 2.01 to 5.0% by mass.
2. A Ti alloy member characterized in that the Ti alloy having resistance to hydrogen embrittlement of claim 1 is used therein.
3. The Ti alloy member according to claim 2 , wherein the Ti alloy member is manufactured by being annealed in a single-phase region.
4. A Ti alloy having resistance to hydrogen embrittlement consisting of Zr, Nb, and a residue consisting of Ti and impurities, in which the content of Zr is 0.1 to 5.0% by mass, and Nb is present in an amount not more than 5.0% by mass.
5. A Ti alloy having resistance to hydrogen embrittlement consisting of Zr, Hf, Nb, and a residue consisting of Ti and impurities, in which the content of Zr and Hf is 0.1 to 5.0% by mass, and Nb is present in an amount not more than 5.0% by mass.
