Abstract (en)

[origin: EP2674506A1] The purpose of the present invention is to provide a titanium alloy member having superior wear resistance and fatigue strength to those of conventional titanium alloys at low cost. Provided is a wear-resistant titanium alloy member having excellent fatigue strength, comprising: a matrix material which comprises, in mass%, 4.5% or more and less than 5.5% of Al, 1.3% or more and less than 2.3% of Fe, 0.25% or more and less than 0.50% of Si, 0.08% or more and less than 0.25% of O, and a remainder made up by titanium and unavoidable impurities; and a cured layer which is formed as a surface layer of the matrix material and is composed of a solid solution of oxygen.
