摘要	The effects of microstructure and texture on the rotating-bending fatigue anisotropy of an anisotropy alpha+ss two- phase titanium alloy by ss forging were investigated. The microstructure and texture distribution of forged billet in different directions and at different thicknesses were characterized by OM, SEM, XRD and EBSD, and the effects of microstructure and texture on the rotating-bending fatigue anisotropy were analyzed. The results show that after ss forging, the alloy has the characteristics of basket-weave microstructure, the prior ss grains are flattened and elongated, and there are recrystallized grains at the grain boundary. The texture of ss- phase < 100 >// axial direction and a-phase < 0001 >// radial direction is formed by forged billet after ss forging. The rotating-bending fatigue strength of radial direction samples is better than that of axial direction samples, which is related to the morphology and texture type of the prior ss grains of forged billet. The arrangement of the prior ss grains leads to different initiations of cracks and different tortuous degrees of crack growth path. In addition, the a and ss textures also cause the fatigue strength differences due to the difficulty of slip systems activation of samples in different directions under cyclic loading.
