Materials and Corrosion, EarlyView.Corrosion inhibitors CuSO4 and NaVO3 achieved up to 98% inhibition efficiency for carbon steel S275 in CO2‐loaded MEA solvent, reducing corrosion rates to 9.4 µm/year—outperforming costly stainless steel SS 316 L at a fraction of the cost. ABSTRACT Corrosion in CO2 capture units significantly impacts safety and costs.

Alloy Qualification for Producing Quench and Tempered Plate Steels with Extra‐Heavy Gage
steel research international, EarlyView.This study develops alloy concepts for ultraheavy steel plates (>100 mm) with ≥690 MPa yield strength. Through dilatometry and Jominy testing, the effects of Mo, Ni, and B on hardenability are quantified. A synergy between 0.5% Mo and 0.5%–1.0% Ni ensures core strength at low cooling rates, while boron microalloying suppresses ferrite and promotes ...

Phase Transformation Behavior of Continuously Cooled Fe–C–V–(Mo) Alloys
steel research international, EarlyView.Additions of vanadium and molybdenum microalloying are shown to reshape phase transformations in clean low‐carbon steels. By tracking microstructural shifts during continuous cooling, the work uncovers the correlation between transformation kinetics, ferrite morphology, and hardness.

steel research international, EarlyView.Prebending of 304L/Q345R cladded plates significantly alters the subsequent weld thermal cycle and modifies the local interfacial microstructure. Combined electron backscatter diffraction (EBSD) and microscopy analysis demonstrates that deformation twinning, martensitic transformation, and defect initiation are concentrated at the trimaterial junction,

steel research international, EarlyView.Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...
