The array of tests included exposure to fresh water and salt water (each alternate wetting and drying regimes) and a high humidity environment. Additionally, accelerated corrosion propagation test were performed to assess the ability of each concrete...

... is evaluated after the test duration, typically 96 hours, in accordance with NACE TM0284-2016. However, HIC propagation behavior during HIC test has not been fully understood. In this study, a new in-situ HIC measurement method has been developed in order to make the connection between HIC propagation...

..., circumferential size and depth of a defect for any given time interval; this enables the acceptability of groups of defects that are predicted to interact to be assessed. Corrosion defects evolve over time and can be considered to have the following three stages: nucleation (birth), propagation (growth) and re...

..., the length of time is shorter for high stresses. Once cracks are initiated, propagation rate can be relatively low as compared to LME. Nevertheless, from a practical view point, the rate of crack growth can be devastatingly fast. Time SCC can occur when the material is stressed above the yield strength...

... ingress during tie-in operations and existence of crevice at the flange interface. Stainless steels are susceptible to crevice corrosion, and based on this corrosion risk, effect of temperature (4°C, 20°C and 60°C) on initiation and propagation of crevice corrosion of three kinds of stainless steels (AISI...
