Beta titanium alloys have been explored in the biomedical field due to the biocompatibility and the low modulus of elasticity. Since a satisfactory fatigue performance is required for load-bearing implants, this work aimed at the evaluation of the fatigue behavior of two beta alloys, Ti-15Mo and Ti-12Mo-6Zr-2Fe, after heat treatment in the beta phase field. The modulus of elasticity was around 90 GPa for both alloys. The determination of the fatigue limit with the staircase method and the Dixon-Mood statistics revealed an increased performance of the Ti-12Mo-6Zr-2Fe alloy, in the range of 700 MPa of maximum stress at 5 million cycles. Omega phase played a fundamental role in the fatigue response of the Ti-15Mo alloy.
