Micro fracture investigations of white etching layers

The fracture behavior of a white etching layer formed on the rail surface in pearlitic steels during the rail-wheel contact is investigated using indentation-based microcantilever fracture tests. The sample thickness is in the order of 5 μm. The local fracture toughness of the white etching layer, its neighboring brown etching layer, martensite...

Study of White Etching Layer in Rail Steel R260Mn by Thermo-Mechanical Simulation

Railway transport plays a vital role in a country’s economic growth. Derailments result in loss of life, damage to rolling stock, service disruptions and harm the environment leading to the decrease in economic growth of a country. Improving train operating safety has been a high priority of the rail industry and the government. Train accidents...
