Influence of Surface Roughness on the Cavitation Wear of P265GH and X2CrNi18-9 Steel Cavitation Generators

Communications, 2018
The aim of this paper was to determine the effect of surface roughness of cavitation generators made from two different materials: P265GH steel, with a ferritic-pearlitic structure, and X2CrNi18-9 (304L) steel with an austenitic structure on the mass ...

Effect of Tempering Temperature on Microstructure and Mechanical Properties of Bainitic Railway Wheel Steel with Thermal Damage Resistance by Alloy Design

Metals, 2020
Thermal damage is one of the principle modes of wagon railway wheels. A new bainitic railway wheel steel with high thermal damage resistance and good combination of strength, plasticity, and toughness was developed.

Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

Advanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

In-situ tensile-shear test in SEM and DIC analysis of two pearlitic steel microstructures: undeformed-coarse and deformed-refined

Journal of Materials Research and Technology, 2023
The deformation and fracture behaviors of undeformed-coarse (UC) and deformed-refined (DR) pearlitic steel microstructure were investigated via in-situ tensile-shear (TS) test in scanning electron microscopy (SEM).

Corrosion Inhibition of S275 Carbon Steel in CO2 Capture Systems Using Monoethanolamine (MEA) Solvent

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.

Influence of surface defects on the fatigue crack initiation in pearlitic steel

MATEC Web of Conferences, 2014
Tensile fatigue tests were performed under load control, with constant stress range Δσ on pearlitic steel wires, from the hot rolled bar to the commercial prestressing steel wire (which has undergone seven cold drawing steps).
