In quality control, microstructures are investigated rigorously to ensure structural integrity, exclude the presence of critical volume defects, and validate formation target microstructure. For quenched, hierarchically-structured steels, morphology bainitic martensitic major concern guarantee reliability material under service conditions. Therefore, industries conduct small sample-size inspect...

The combined influence of prior plastic strain in the austenite, and applied stress in the course of the transformation, on the crystallographic texture of a bainitic steel was studied in this work. The experimental data were obtained using Electron Back Scatter Diffraction (EBSD) method and analyzed using two methodologically different approaches. It was concluded that the plastic deformation ...

Thermo-mechanical treatments using continuous cooling after forging are an established method for producing bainitic steels, mainly because of the elimination energy intensive additional heat treatment processes. The is usually employed in uncontrolled manner industrial sector, which can be detrimental to resulting microstructural morphology and, consequently, final product properties. In this ...

This research work aims to study the effect of 2wt%Mo on bainitic transformation kinetics and bainite morphology in 0.6wt%C-1.2wt%Si-1.0wt%Mn-0.2wt%Cr steel. Specimens are austenitized at 950°C rapidly cooled salt bath isothermally treated between 200°C–300°C for different time intervals. Another set specimens oil after an austenitization treatment then tempered temperature range 200°C–550°C. I...

Pipelines have been installed and operated around the globe to transport oil gas for decades. They are considered be an effective, economic safe means of transportation. The major concern in their operation is corrosion. Among different forms corrosion, stress corrosion cracking (SCC), which caused by stresses induced internal fluid flow or other external forces during pipeline’s operation, com...
