Abstract

Low rigidity titanium alloy, Ti-29Nb-13Ta-4.6Zr, for biomedical applications has been newly developed. Fatigue and fretting fatigue characteristics of Ti-29Nb-13Ta-4.6Zr, which are important factors for biomedical applications, were examined in air and simulated body environment, that is, Ringer's solution in this study. Fatigue strength of Ti-29Nb-13Ta-4.6Zr increases with conducting aging treatment after solution treatment. Fretting fatigue damage is lowered with decreasing modulus of elasticity in this study. Fatigue strength of Ti-29Nb-13Ta-4.6Zr is not degraded in Ringer's solution. Fretting fatigue strength of Ti-29Nb-13Ta-4.6Zr is a little greater than that in air in low cycle fretting fatigue region, but a little smaller than that in air in high cycle fretting fatigue life region.
