The wheel/rail rolling contact fatigue was systematically explained in terms of its
classification, initiation mechanisms, influencing factors, consequences, as well as …

The railway track dynamic behavior shows intense characteristics in a wide frequency
domain, which plays an major role in the generation of wheel-rail rolling noise and the …

Eddy current testing (ECT) is widely applied to detect surface defects on metallic materials.
In ECT for cracks on complex curved surfaces, immunity to lift-off and the detection ability of …

Two heat-treatment routes of bainite austempering, namely above-Ms austempering and
below-Ms austempering, were applied on a low carbon rail steel. The obtained multiphase …

The comparison of wear resistance of bainitic and pearlitic steel is still a matter of
controversy. In this study, the dry rolling-sliding wear behaviors of three types of pearlitic …

The microstructures of the Fe-based alloy laser cladding layer were characterized by optical
microscope, scanning electron microscope and X-ray diffractometer. The load-bearing …

Ultrasonic surface rolling (USR) treatment with different rolling loads (600, 800, 1000 and
1200 N) was introduced to the 17Cr2Ni2MoVNb steel. The microstructure and rolling contact …

The effects of low temperature on the adhesion coefficient under both dry and degraded
adhesion conditions are investigated using a rolling-sliding apparatus. The results indicate …

In order to improve the resistance to damage of rail materials, laser dispersed quenching
(LDQ) with different quenching ratios was studied. The results indicated that the application …
