Modeling studies of corrosion fatigue in a low carbon steel

This paper presents the results of the modeling studies of the simultaneous action of applied cyclic stress and the corrosion of low-carbon steel in environments with different pH levels (pH of 3, 5, 8, and 11). The evolution of fatigue cracks from corrosion pits is explored using scanning electron...
