Abstract
In this research, rotating bending fatigue test at minimum to maximum stress ratio of
R=-1 was used for investigating the fatigue behavior of Ti-6Al-4V alloy. Both smooth and notched
specimens, with elastic concentration factor, kt, of approximately 3.6 and 4.1 were used for this
purpose.
In addition, the effect of variation in ultimate tensile strength, UTS, on the fatigue behavior of this
alloy was studied. S-N curves were drawn and the value of notch sensitivity was obtained for each
case.
The results showed that the presence of notch in Ti-6Al-4V alloy has a different amount of
sensitivity when the notched specimens were subjected to high cycle fatigue (HCF) and low cycle
fatigue (LCF) tests. However, the notch sensitivity of this alloy was shown generally to be much
lower than steel alloys with similar UTS values. Thus, considering the high compatibility of this
alloy with the body environment and its low sensitivity to notch, one can strongly recommend this
alloy for use in biomedical application.
