’A Poll Tax on Wheels’: Might the move to Privatise Rail in Britain have Failed? [PDF]
, 2010 Rail privatisation was a controversial, widely unpopular policy whose implementation was not inevitable. This article employs counterfactual history methodology to examine whether the move to rail privatisation in Britain might have failed. It places the

steel research international, EarlyView.Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

LGR-Net: A Lightweight Defect Detection Network Aimed at Elevator Guide Rail Pressure Plates
SensorsIn elevator systems, pressure plates secure guide rails and limit displacement, but defects compromise their performance under stress. Current detection algorithms face challenges in achieving high localization accuracy and computational efficiency when ...

The effect of white etching layer patches on a larger rail defect
MATEC Web of Conferences, 2017 Manufacturing defects such as porosity that formed in the rail could result in catastrophic failure if it remain in service. In this study, a crack that initiated from a large void was modelled using boundary element model to investigate the effect of ...

steel research international, EarlyView.The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

steel research international, EarlyView.Strain‐induced NbC precipitation governs hot‐deformation resistance in CrNiMnMoB ultrahigh‐strength steel by suppressing dynamic recrystallization, increasing activation energy, and refining martensitic substructures. The precipitation response is controlled by temperature, supersaturation, and strain rate, with slow deformation promoting extensive NbC

Deep Learning (Fast R-CNN)-Based Evaluation of Rail Surface Defects
Applied SciencesIn current railway rails, trains are propelled by the rolling contact between iron wheels and iron rails, and the high frequency of train repetition on rails results in a significant load exertion on a very small area where the wheel and rail come into ...
