“…In contrast, in Arica, which had the same corrosion rate as Antarctic but where the corrosion product film was not formed homogeneously, ductility decreases by almost 40%. M. Okayasu et al [ 44 ], through simulations, found that areas near pitting corrosion have high levels of stress. This comparison reveals that as corrosion increases, so the corresponding elongation of the steel decreases before failure.…”

Resistance to atmospheric corrosion in different environments located in Chile and the corrosion’s effect on the mechanical properties of SAE 1020 steel were studied. Atmospheric corrosivity categories at each station under study were determined. These categories were C2, for Laja; C3 and C4, for the Arica and Antarctic stations, respectively; and the most aggressive, C5 and higher at Quintero. These specific environments significantly influenced the mechanical responses of steel exposed for 36 months. Rupture elongation, the modulus of toughness, ultimate tensile strength, and hardness of the material all decreased as a function of environmental atmospheric aggressiveness. Lowered ductility is the result of the increased corrosion rate due to the high deposition of chlorides. This is due to the morphology of material degradation, which consequently occurs as pores, microstrains, and other defects that promote early rupture of the steel.

“…Corrosion fatigue will occur easily under the common influence of complex external stresses, which will reduce the service life of steel wire. There are many factors affecting the corrosion fatigue life of metallic materials, such as the mechanical properties [ 7 , 8 ], the material properties [ 9 , 10 , 11 ], the environmental factor [ 12 , 13 , 14 , 15 , 16 , 17 ], and the stress states [ 18 , 19 , 20 , 21 ]. Among them, the corrosion environment can determine the corrosion reaction kinetics characteristic.…”

Abstract:In this work, the effects of loading condition and corrosion solution on the corrosion fatigue behavior of smooth steel wire were discussed. The results of polarization curves and weight loss curves showed that the corrosion of steel wire in acid solution was more severe than that in neutral and alkaline solutions. With the extension of immersion time in acid solution, the cathodic reaction of steel wire gradually changed from the reduction of hydrogen ion to the reduction of oxygen, but was always the reduction of hydrogen ion in neutral and alkaline solutions. The corrosion kinetic parameters and equivalent circuits of steel wires were also obtained by simulating the Nyquist diagrams. In corrosion fatigue test, the effect of stress ratio and loading frequency on the crack initiation mechanism was emphasized. The strong corrosivity of acid solution could accelerate the nucleation of crack tip. The initiation mechanism of crack under different conditions was summarized according to the side and fracture surface morphologies. For the crack initiation mechanism of anodic dissolution, the stronger the corrosivity of solution was, the more easily the fatigue crack source formed, while, for the crack initiation mechanism of deformation activation, the lower stress ratio and higher frequency would accelerate the generation of corrosion fatigue crack source.
