Abstract
The fatigue strength of an annealed Ti-15Zr-4Nb-4Ta alloy at 1 Ã 108 cycles was approximately 730 MPa. The fatigue strength of its alloy was much improved following an ageing treatment after a solution treatment. The tension-to-tension fatigue strengths of annealed Ti-6Al-4V, V-free Ti-6Al-7Nb, Ti-6Al-2Nb-1Ta, and Ti-15Mo-5Zr-3Al alloys at 1 Ã 108 cycles were approximately 685, 600, 700, and 350 MPa, respectively. The ratios of fatigue strength at 1 Ã 108 cycles to ultimate tensile strength for the α- and (α + β)-type Ti materials were higher than 65%.
