This work presents a study on the fatigue crack initiation in the presence of stratified surface
layers (SSL)–a combination of white and brown etching layer–on rail wheels. Reproducible …

With rail travel getting more popular more demands are being put on rail infrastructure. The
wheel/rail contact is the one of the main parameters that is key to maintaining a high …

The subject of the research in this work was the S49 rail made of R260 rail steel (1.0623).
The carried out investigations concern microstructure tests and tests of mechanical …

High carbon Cr‐bearing SAE 52100 is widely used for bearing production. The in‐service
microstructure of bearing steel is tempered high C martensite, which has superior …

It is important to know tribological properties of rail and wheel for predicting the service life of
both components. In railway, the tribological system is open and the harsh working condition …

In operating conditions, railroads are subject to abrasive and fatigue wear. Their durability
period depends on the properties of the materials from which rail sections are made, the …

The properties of pearlitic steel are controlled by pearlite characteristics, which in turn
depend on transformation temperatures. This work aims to study the relationship between …

Purpose: Cutting sheets of various materials is a commonly used product finishing process
in industrial conditions. If high quality of cut edges is required, defects caused by cutting on a …

Medium carbon steels are commonly used for railway wheels due to a good balance of
hardness and fracture toughness, as well as solid wear properties. Among rail wheel steels …

In this study, the effect of WC coating on the tribological performance of rail steels was
investigated by roller on plate wear tests and potentiodynamic polarization corrosion tests …
