2022, Corrosion ScienceThe effect of crack tip environment on crack growth behaviour of a low alloy steel at cathodic potentials in artificial seawater
2020, Journal of Materials Science and TechnologyCitation Excerpt :Some researchers have shown that the dissolved metal cations will hydrolyse to produce H+, resulting in the acidification at the crack tip [7,13,14]. Sandoz et al. [13] discovered that pH at the crack tip of various types of alloy steel was in the range of 3.6–3.8. Cooper and Kelly [14] identified that the crack tip pH of alloy steel was approximately 3.0 in a near-neutral solution.

2020, Corrosion ScienceHierarchical analysis of alloying element effects on gas nitriding rate of Fe alloys: A DFT, microkinetic and kMC study
2019, Acta MaterialiaCitation Excerpt :The overall morphology of the model system is shown in Fig. 1 (a). Less than 5 wt % of alloying elements such as C, Mn, Si, Cr, Ni, Mo, and V were introduced into the Fe matrix [20–22]. We replaced one of the 45 Fe atoms with an alloying element to construct a 2.22 at.
The effect of sensitization and fatigue loading frequency on corrosion fatigue of AA5083-H131
2019, International Journal of FatigueCitation Excerpt :As such, the high f data was typically collected at shorter crack lengths than the high f data. Longer cracks are predicted to have more acidic electrolytes [57–66], which could cause an increase in da/dN from either increased H production and uptake per HEAC or increased crack tip dissolution for crack advance. Note, there is no f dependence for DoS of 33 mg/cm2 and below.
