On the composition base of commercial X65 grade pipeline steels, a Cu modified steel was designed to show improved resistance microbially induced corrosion (MIC). The mechanical properties Cu-added and its behavior in soil solution inoculated with sulfate-reducing bacteria (SRB) were investigated this work. results demonstrated that exhibits good combination strength toughness. ions released fr...

In this study, an electrochemical hydrogen permeation experiment was used to determine the diffusion parameters, and a microprint test visualize distribution of in X65 pipeline steel with different levels cold deformation. The curves show that both current density effective coefficient decrease increasing reversible irreversible traps is calculated from it found amount increases deformation, es...

This paper evaluates the effects of microbiologically influenced corrosion (MIC) on fatigue-crack growth of candidate materials useful in expanding bio-ethanol usage, including a storage-tank steel (ASTM A36) and two pipeline steels (API 5L X52 and X70). The microbiological species sampled and cultivated from an ethanol fuel production stream are responsible for both acetic acid and hydrogen su...

Low-carbon steel is widely used in industrial pipelines, and corrosion studies are focused mostly on erosion-corrosion, its prediction control. In this paper, the rate pipelines modeled using a flow loop measured by linear polarization resistance method (LPR) 3-electrode setup for API-5L-X65 QT steel. Optical microscopy SEM conducted to examine surface of sample products. The effect NaCl concen...

In the last few decades, great effort has been spent on advanced material testing and development of damage models intended to estimate ductility fracture ductile metals. While most studies focused static are applied at room temperatures only, in this paper, multiaxial tests have executed investigate effects dynamic action temperature mechanical behavior an API X65 steel. To end, a Split Hopkin...

Near-neutral pH and a low redox potential are considered favorable conditions for immobilizing radionuclides in deep repository systems within clay formations. Cigeo is the future French Industrial Center Geological Disposal high- intermediate-level long-lived radioactive waste, to be built at depth of 500 m Callovian–Oxfordian clay. In-depth knowledge mechanisms kinetics corrosion occurring on...
