A three-dimensional multiscale model of intergranular hydrogen-assisted cracking [PDF]
, 2010 We present a three-dimensional model of intergranular hydrogen-embrittlement (HE) that accounts for: (i) the degradation of grain-boundary strength that arises from hydrogen coverage; (ii) grain-boundary diffusion of hydrogen; and (iii) a continuum model

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Electrochemical Behavior and Corrosion Products of Casing Steel under CO2 Condition
International Journal of Electrochemical Science, 2019 The anodic reaction of CO2 corrosion of steel is closely related to the formation and characteristics of the corrosion product film. However, the relationship between the anodic reaction and the corrosion product film has not been studied.

Corrosion Inhibition of API 5L X52 Carbon Steel by 1-ethyl-3-methylimidazolium-methanesulphonate and 1-ethyl-3-methylimidazolium Acetate Ionic Liquids in Hydrochloric Acid [PDF]
Archives of Metallurgy and Materials, 2020 The corrosion inhibition behaviour of 1-Ethyl-3-methylimidazolium-methanesulphonate (EMIM[MS]) and 1-Ethyl-3-methylimidazolium acetate (EMIM[Ac]) on API 5L X-52 carbon steel in 2 M HCl was investigated using weight loss, potentiodynamic polarization and ...

Advanced Engineering Materials, EarlyView.The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Experimental Study on Alternating Current Corrosion of Pipeline Steel in Alkaline Environment
International Journal of Electrochemical Science, 2016 The variation of the topsoil pH value in the X70 steel surface was studied under the AC corrosion process. The cyclic voltammetry technique was employed to investigate the AC action mechanism on the X70 pipeline steel in a soil environment.

Mechanism of metal dusting corrosion by pitting of a chromia-forming alloy at atmospheric pressure and low gas velocity [PDF]
, 2016 FeNiCr samples (800HT) were exposed at 570 °C, 1 bar to a 47.25CO-47.25H2-5.5H2O atmosphere (ac = 33) flowing at 18 μm/s. Pitting corrosion was observed. Pits showed a flattened morphology and a constant pit diameter growth rate. Corrosion rings appeared
