Abstract The present work investigates the resistance of a progressively cold-drawn carbon steel wire against hydrogen embrittlement. In this study, analytical and numerical methods are used to determine critical content, ratio embrittlement indices different material conditions. with highest degree cold deformation shows content improved At higher degrees deformation, stronger trapping, which ...

Rail grinding is a maintenance task performed in the field to return it profile and/or remove damage, however, can affect surface integrity of rail. In this paper, damage resistance three different ground rails (R260, R350HT and R400HT) was evaluated. samples were using same parameters low-traffic line field. The rail metallurgy then examined, white etching layer (WEL) formation wear rolling co...

Cover: Schematic diagram of the corrosion forms in a synthetic solution representing Callovo-Oxfordian porewater during month at 120°C observed on (left) ferrito-pearlitic steel and (right) ferritic samples. The composition structure product layers appear very similar. They are composed bilayer siderite enriched calcium magnesium, with magnetite islets internal layer calcite metal original surf...

The objective of this work is to investigate the microstructure evolution railway pearlitic wheel materials (ER7, CL60 and C-class) under a rolling-sliding contact loading. Firstly, microstructures steel at different depths from strain-free matrix top surface were systematically investigated via laser scanning confocal microscope (LSCM), electron microscopy (SEM), backscattered diffraction (EBS...

Corrosion experiments were performed on a ferrito-pearlitic (P285-NH) and ferritic steel (Armco) in synthetic solution representing the Callovo-Oxfordian porewater during month at 120°C. product layers (CPLs) characterized from micro to nanoscale terms of morphology (electron microscopies), composition (energy dispersive X-ray spectroscopy), structure (µ-Raman, selected area electron diffractio...
