specimens was experimentally observed, which, being very similar to the theoretic prediction, serves to validate the applied methodology. After the process of pre-corroding the specimens, these were submitted to quasi-static tensile tests and the results were then compared to ones from not corroded specimens. It was concluded that the induced surface corrosion (equiv alent to half a year) did not have a significant e ff ect. The specimens demonstrated some level of ductility, as necking was present and large elongations at ultimate strength and after fracture were registered, averaging 6.63% and 19.39% respectively. Moreover, the yield strength remained above 690 MPa and the results for the corroded and not corroded conditions were similar. As a future work the same methodology, for induced accelerated corrosion, will be applied to pre-corrode high cycle fatigue specimens, with the objective of investigating how the fatigue behaviour in this regime is a ff ected.
