TITANIUM ALLOY MEMBER

摘要

A titanium alloy member characterized in that it comprises titanium (Ti) in an amount of 40 wt % or more and one or more elements other than titanium belonging to the IVa Group and/or the Va Group in an amount such that the total content of titanium and said one or more elements is 90 wt % or more and one or more of the interstitial element group consisting of oxygen, nitrogen and carbon in a total amount of 0.25 to 2.0 wt %, and has, as its basic structure, a body-centered tetragonal structure or a body-centered cubic structure having a ratio of an interatomic distance on the c axis to that on the a axis (c/a) of 0.9 to 1.1. The titanium alloy member exhibits an excellent formability which conventional titanium alloys have never achieved, together with flexibility and high strength, and thus can be used for a variety of products.
