| description | To provide a titanium alloy sheet in which coarsening of crystal grains is suppressed under a high-temperature environment, and high-temperature strength is excellent.SOLUTION: A titanium alloy sheet contains Cu, Sn, Si, Nb and Al, contains one or both of Cr and Mo, Fe and O are limited to 0.06% or less and 0.07% or less respectively, contains one or two or more kinds of Ni, V, Mn, Zr, Co, Ta, W, C and N by 0.3% or less in total, balance is Ti and impurities, in which a metallic structure consists of an α phase and a second phase, the average crystal grain diameter of the α phase is 10 to 50 μm, and the number of measurement areas having the number density 0.01 piece/μm2 or more is 80% or more of all measurement areas.SELECTED DRAWING: None
【課題】高温環境下で結晶粒の粗大化が抑制され、高温強度に優れたチタン合金板を提供する。【解決手段】Ｃｕ、Ｓｎ、Ｓｉ、Ｎｂ、Ａｌを含有し、Ｃｒ、Ｍｏの一方または両方を含有し、Ｆｅを０．０６％以下、Ｏを０．０７％以下に制限し、Ｎｉ、Ｖ、Ｍｎ、Ｚｒ、Ｃｏ、Ｔａ、Ｗ、Ｃ、Ｎの１種または２種以上を合計で０．３％以下含有し、残部がＴｉ及び不純物であり、金属組織がα相と第二相からなり、α相の平均結晶粒径が１０〜５０μｍであり、個数密度が０．０１個/μｍ２以上の測定領域の数が全測定領域の８０％以上であるチタン合金板を採用する。【選択図】なし |
