This study discusses a Tγ/A method of plotting wear data from a twin-disc machine for
identifying the wear and damage transitions of wheel and rail materials. As found in previous …

There is an increased demand for railway services, which has resulted in an increase in
speeds and axle loads. The increase in axle loads and speeds have resulted in an increase …

Wheel–rail contact creates high stresses in both rails and wheels, which can lead to different
damage, such as plastic deformation, wear and rolling contact fatigue (RCF). It is important …

This paper presents a new approach for modelling the wear in wheel-rail contacts for a wide
range of test and contact conditions (material pairing, load, creep, lubrication etc.) in the mild …

Tribology is the science of friction, wear, lubrication and contact mechanics. The wheel-rail
interface is one of the most complex machine element contacts from a tribological …

This work presents a ratcheting mechanism-based numerical model to study the initiation
location and initiation life of rolling contact fatigue (RCF) or wear damage and the initial …

Rolling contact fatigue (RCF) and wear are inevitable problems for wheels and rails.
Recently, increasing vehicle speeds and axle loads have led to the need for an increase in …

Industrial revolution in engineering materials applications through additive manufacturing
has influenced the steel application in engineering industry. Limitations of wear of carbon …

The pin-on-disc test model system was used to simulate contact wear between wheel flange
and rail gauge corner. Pins were extracted from a class C cast steel wheel and discs were …

In this study, an ultrasonic nanocrystalline surface modification (UNSM) technique was
applied to normal and heat-treated rails made of 60 kgK steel to enhance the wear …
