... corrosion because local corrosion damages are likely the sites of local stress concentration and crack initiation. Currently these infrastructures are designed only for approximately 20-25 years of life, which is unsustainable not only from lifecycle assessment point of view, but also for generating...

...Abstract Localized corrosion poses a critical challenge for geothermal systems due to the presence of high temperatures and corrosive species such as chlorides, acid gases, and dissolved oxygen. Models that can accurately predict the risk of localized corrosion are thus essential for effective...

... the corrosion of low alloy steels (P110 and 3Cr) and stainless steels (13Cr and 316), especially promoted the localized corrosion of 13Cr stainless steel. The critical oxygen content and the suitability of several materials for use in oxygen-containing environments were discussed. Based on a comprehensive...

...Abstract Localized corrosion can occur in pipelines transporting crude oil in areas of the pipeline where water wets the pipe surface either during operation or shutdowns. This has been attributed to the presence of CO₂, and in some cases O₂, in the crude oil which dissolves...
