.... To address this weak point, a new advanced alloy with increased molybdenum content, which will be called Alloy 825 CTP, was developed. Previous corrosion tests showed an increased critical pitting temperature measured on the new alloy 1 and based on these data further corrosion tests were performed. Alloy...

... under laboratory and field exposures. From the results, it is possible to better understand the atmospheric corrosion of steel and zinc under various exposure conditions. The technique should also allow the design of reliable and realistic corrosion tests for different industrial applications...

... an often-interesting choice in terms of cost-benefit ratio. During welding and materials qualification steps, the most commonly specified test for checking localized corrosion resistance of CRA, in particular in chloride-containing environments, is the ferric chloride ASTM(1) G48 corrosion test. So, many...

... available X65 pipe. The steels were cut into two sizes: 115 mm × 18 mm × 3 mm as stressed samples for SCC test and 75 mm × 19 mm × 3 mm as unstressed samples for corrosion test. For mechanical tests, the samples were machined into the standard sheet-type specimen based on ASTM E8.8 Note that all the samples...

... for the other three features were not shown clearly. In the present work, pitting corrosion tests and crevice corrosion tests of AM N06210 in green death solution (11.5 %H 2 SO 4 + 1.2 % HCl + 1 % FeCl 3 +1 %CuCl 2 ) were conducted to estimate the sensitivity to localized corrosion and metallographic analysis...

..., the relation between concrete crack width and corrosion- induced mass loss of steel bar was studied in a probabilistic way. Concrete block specimens containing steel bars were prepared and subjected to accelerated corrosion test (ACT). Three concrete cover thicknesses were considered including 25.4 mm, 50.8 mm...

... and to evaluate crevice corrosion in H2S environment with this dope-free solution. Atmospheric corrosion was evaluated after long-term exposure to natural environments and accelerated cyclic corrosion tests in a lab. Resistance to crevice corrosion was assessed through specifically designed high pressure and high...

.... Concrete block specimens containing steel bars are prepared and subjected to accelerated corrosion test. As the corrosion-induced mass loss of steel bars reaches different levels ranging from 0% to 30%, the tests are terminated. The steel bars are taken out of the concrete block, cleaned with a sand...

... vapor phase corrosion inhibitor was investigated. Electrochemical tests were conducted and showed a significantly lower corrosion rate in steam generating boilers and boiling water. Short term (720 hours) corrosion tests in boiling water showed a decreased corrosion rate from 5.3 mpy to 1.93 mpy for 50...

... of the base material (not tested in geothermal environment) for comparison to the analysis of the tested specimens. The specimens used for the geothermal corrosion test were prepared in accordance with standard ASTM G4-08 [1]. They were polished using SiC paper (down to 1200 grit) cleaned with alcohol...

.... In addition, the specimen employing 100% N2 back shielding gas with 2,000 ppmO2 was acceptable in corrosion test. It was observed that the corrosion resistance of SDSS weld joint is mainly affected by depletion of nitrogen in the surface of root bead and less affected by oxygen content levels. The nitrogen...

.... Current corrosion tests and measurement methods for qualification and selection of aerospace coatings often provide poor correlation to service environment performance and do not assess the highest risk failure modes of localized corrosion, galvanic attack, and environment assisted cracking. Furthermore...

It was also shown that welds containing these flaws suffered enhanced corrosion in ASTM G48A 1 pitting corrosion tests. Because of their effects on environmental...

.... Accelerated corrosion tests were performed periodically and the corrosion rates at different time intervals were measured with linear polarization resistance (LPR). The change in the resonant wavelength over time was recorded using an optical spectrum analyzer (OSA). After corrosion test, all the steel straws...
