Abstract

X-ray synchrotron tomography was used to investigate the fatigue corrosion behavior of A17075-T651 alloys in a corrosive solution. Single edge- notch specimens machined along the L-T orientation were used for corrosion-fatigue testing, under a load ratio of R = 0.1. The evolution of reaction between the corrosive fluid and the metal was observed, as well as the formation of hydrogen bubbles. The shape of these bubble also changed significantly during the fatigue cycle. The fatigue crack growth rate was found to be significantly higher in the corrosive solution, compared to crack growth in air, for stress intensity levels between 5 and 10 MPa √m.
