“…The four types of wheel steel in this study are intended for trains, and the number labeling and chemical compositions in weight percentage of these materials are shown in Table 1. The carbon content of materials #3 and #4 were slightly higher than common wheel materials [4,7,13]. The main difference in composition among the four materials was the amount of carbon, which varied from 0.51 % to 0.72 %.…”

The fatigue and wear characteristics of four different steel wheel materials are investigated in detail by using rolling contact fatigue and wear bench tests on a JD-1 apparatus, analyzing chemical composition and hardness, and performing profile analysis and micro-morphology analysis. The wear and fatigue behavior of one of the materials under different operation speeds is also investigated. The results show that the wear resistance of the materials has a positive correlation with their carbon content, while fatigue resistance has a negative correlation. Based on hardness analysis as a function of depth into the specimen, the thickness of layers with a steep hardness gradient has a negative correlation with the initial surface hardness in the tests using different materials. The hardness increments, however, have a positive correlation with initial surface hardness. The rolling tests on one material using different rotation speeds show that the hardness increments and the thickness of layers with a steep hardness gradient increase with the rotation speed. The analyses and experimental results demonstrate that two of the four materials exhibit good wear resistance and rolling contact fatigue resistance, making them suitable for either highspeed or heavy axle railroad operations.

“…The manufacturing of railway wheels involves heat treatments in order to achieve desirable characteristics in mechanical properties and residual stress distributions. After heat treatments, the forged and rolled wheels have a running surface consisting of fine-lamellar pearlite, a structure of alternating hard cementite and softer ferrite lamellae with a lamellar spacing of around 130 nm, and about 5-10% pro-eutectoid ferrite decorating the previous austenite grain boundaries [2,3]. The high temperatures occurring during operation can however degrade the microstructure, more specifically spheroidize the pearlitic microstructure.…”

Railway wheels are commonly made from medium carbon steels (~0.55 wt.% C), heat treated to a near pearlitic microstructure with 5–10% pro-eutectoid ferrite. During the operation of freight trains, where block brakes are used, high thermal loads occur together with the high contact stresses, which combined can affect the mechanical properties of the material. In this study, the effects of annealing on local microstructure and mechanical properties in pearlitic railway wheel steel were investigated using electron microscopy and micro-hardness. It is found that after annealing at 650 °C, the room temperature hardness reduces about 25%, accompanied by significant spheroidization of cementite in the pearlitic colonies, though the size and the orientation gradients of the pearlitic colonies have not changed much. The relationship between the microstructural changes and the mechanical properties are discussed.

“…At present, researches on surface damage of wheel–rail mainly focus on various aspects, such as materials improvement, 3,4 numerical simulation, 5 interaction force between wheel and rail, 6 factors affecting RCF, wear and damage mechanisms of wheel–rail, alleviation of damage, 7,8 corrugation, 9–11 etc. For the inevitable vibration in the wheel–rail contact, the vibration signals can reflect information of surface damage of wheel–rail.…”

The objective of the study was to explore the vibration signal responses on the surface damage of wheel materials using a JD-1 wheel–rail simulation facility. Vibration signals were extracted using the methods of local mean decomposition and Hilbert envelope spectrum. The surface damage of wheel rollers varies with different tangential forces. The results indicate that the surface damage of wheel materials has a corresponding characteristic frequency under different tangential forces conditions. When surface cracks appear on the surface of wheel rollers, the characteristic frequency of wheel roller is about 1830 Hz. However, the characteristic frequencies are about 800 Hz and 73 Hz for peeling and spalling damage on wheel roller. Multifractal dimensions of the vibration signals quantificationally identify and distinguish the surface damage types of wheel rollers, which can provide a meaningful guidance for the subsequent online detection of surface damage of wheel materials.
