The thin White Etching Layers (WELs) commonly exist on the surfaces of different rail grades in railway networks worldwide. Although the formation of WELs has been the subject of interest for a few decades, precise conclusions on their formation mechanisms are still in argument. Two popular hypotheses for WEL formation have been proposed concerning thermomechanically/thermally-induced and mechanically-induced WELs, respectively. Each type of WELs was formed in different operating conditions and had different microstructure, hardness, composition, and WEL/pearlite interface features. The invest...

White Etching Layers (WELs) were found to form on different rail grades in the railway networks across the world. The presentence of WELs on the rail promotes rolling contact fatigue defects, which is detrimental to railway transportation safety. However, the formation and evolution of WELs on different rail grades are not fully understood, as is their contribution to the formation of RCF defects on different rail grades. The extensive field monitoring, laboratory experiment, and material characterization were carried out to systematically investigate the formation mechanism and evolution of W...
