“…Developing premium wheel materials with improved tribology properties have been considered to be an effective way to prevent such degradations. Wheels with different microstructures, such as bainitic wheels [2], laser cladding wheels [3], spheroidized pearlite wheels [4], etc., have been widely developed. However, the traditional lamellar pearlitic wheel steels are still commonly used in railways in various countries because of their excellent wear and RCF resistance and superior work-hardening ability.…”

“…Lian and others [15] conclude that the formation of white etching layers will speed up crack formation and failure of wheel/rail materials. Nevertheless, relative investigations into the impacts of the damaged layer of wheel/rail materials induced by mechanical processing during the process of contact fatigue haven't been that detailed [16] [17] [18]. This present paper is investigating the contact fatigue property of D2 highspeed wheel steel by using rolling fatigue tester.…”

Through the rolling contact fatigue experiment under the condition of the lubricating oil, this article investigated the relation between contact fatigue property and microstructure on the surface layer of D2 wheel steel. The results showed that although the roughness of the original specimen induced by mechanical processing would diminish to some extent in the experiment, the 0.5-1.5 μm thick layer of ultrafine microstructure on the original mechanically-processed specimen surface would still become micro-cracks and small spalling pits due to spalling, and would further evolve into fatigue crack source. Additionally, even under the impact of the load that was not adequate to make the material reach fatigue limit, the ferrite in the microstructure underwent plastic deformation, which led the refinement of proeutectoid ferrite grains. During the experiment, the hardening and the refinement caused by plastic deformation consisted with the theory that dislocation gave rise to plastic deformation and grain refinement. The distribution laws of hardness and ferrite grain sizes measured could be explained by the distribution law of the shearing stress in the subsurface.

“…In recent years, the high strength low alloy steels (HSLA) have attracted significant interest in applications with excellent formability for the bridge and building industries [1][2][3]. Refining the pearlite interlamellar spacing and grain size of steels can effectively improve the mechanical properties and elongation rate of steel [4][5][6]. In engineering structure, HSLA steels are the key point that ensures structural safety of earthquake-resistant frames during major earthquake [7].…”

The influences of Nb elements and hot deformation on the strength of steels were investigated. The microstructures and mechanical properties of the steels are determined through optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and tensile tests. The nanometer sized carbide particles precipitates in the grain boundary are attributed mainly to severe deformation at high temperature. Of the two steels with different content of Nb elements and deformation, the strength of 2#steel was more lager due to more content of Nb can form more precipitates to limit grains growth. The results show that the microstructures and mechanical properties of the steels are significantly affected by the content of Nb elements, but are only slightly affected by the deformation.
