Abstract

Through the systematic replacement of Co for Cu as a β-Ti phase stabilizer in the γ-TiCu alloy, a wide range of (β+γ) two-phase microstructures can be prepared in the Ti₅₀Cu_50-xCo _x alloys. Enhanced yield strength (>850 MPa) combined with high ductility (>22%) of the Ti₅₀Cu₄₀Co₁₀ alloy is attributed to the formation of micron-scaled β dendrites embedded in theγ matrix. By controlling the volume fraction of the β dendrites, simultaneous increases in strength and ductility can be effectively achieved.
