摘要：
This paper analyzes the role of crack tip blunting in stress corrosion cracking by localized anodic dissolution of high-strength eutectoid steel. The results of the tests show an apparent improvement of fracture resistance in aggressive environment - measured in terms of critical stress intensity factor - in relation to its reference value in an inert (air) environment. The explanation can be sought in the effects of crack tip blunting, i.e., of the increase of crack tip radius as a consequence of the dissolution process.
