Mechanisms of microstructural damage during rolling contact fatigue of bearing steels
… where microstructural damage manifests as dark-etching regions and white-etching areas, which display different properties from the surrounding region. The aim of this study is to identify the mechanisms for such damage and to suggest models that can explain the influence of the initial …

Microstructural alterations in bearing steels under rolling contact fatigue
… formed in rolling contact fatigued bearings – dark etching regions (DERs), white etching bands (WEBs) and white etching areas (WEAs). Very good agreement is obtained between the predications made by the models and the experimental data from both this research and the literature. Moreover, the …

Finite Element Modelling of Deep Zone Residual Stresses in Rolling Contact Bearing Elements.
… different microstructural features, termed as dark etching regions (DERs) and white etching bands (WEBs); visible after Nital etching. Intensive work has been carried out in the past few decades to define these microstructural changes along with mechanical properties evolution, however, its …
