Abstract : An empirical approach to fatigue design has not prevented structural fatigue failures. One area that needs greater emphasis is the interface of microstructure with its application. Therefore, in this study commercially pure titanium has been heat treated to establish various microstructures. Unnotched fatigue specimens were used for traditional S-N tests and center crack panels were used for crack growth tests. The test results then were examined in order to determine the effect microstructure has on the fatigue life of titanium. This effect was more prevalent in the near-threshold crack growth region.
