The fatigue crack propagation characteristics of the Ti-6Al-2Sn-4Zr-6Mo forged bar in as-solutionized and aged conditions were investigated. Fatigue crack propagation rate in Paris' regime is smaller in as-solutionized conditions than in aged conditions. Crack closure is greater in as-solutionized conditions than in aged conditions. The deformation-induced martensite is detected on the fatigue fracture surface of the as-solutionized Ti-6Al-2Sn-4Zr-6Mo. Deformation-induced transformation is one of the main causes of inducing crack closure and retarding fatigue crack propagation of the as-solutionized Ti-6Al-2Sn-4Zr-6Mo.
