In the present work, rotating bending fatigue tests have been carried out to investigate the fatigue strength of plain and circumferentially notched specimens of Ti-6AL-4V alloy. The purpose of this work is to evaluate fatigue strength and notch sensitivity under different stress concentrations . The notch radius of specimens changes from m (plain specimen) to 1.3, 0.4, 0.2, and 0.1 mm. The fatigue cracks initiate by approximate 25% of cycle ratio in the cases of p= 1.3 and 0.4 mm while the fatigue cracks initiate by approximate 15% in the case of p = 0.2 mm. The notch sensitivity of Ti-6AL 4V alloy is higher Ahan that of cast iron, and lower than that of steel material. The non-propagating micrwcracks at the specimen surface are not existed for not only the plain specimen but also for all of the notched specimens including plain specimen under fatigue limit by N = 1 X 10' cycles.
