EBSD study of early-damaging phenomena in wheel–rail model test

In the early-damage regime of rails subjected to rolling contact fatigue, the material undergoes severe plastic deformation forming a modified sub-surface microstructure. This zone close to the surface determines subsequent fatigue properties of the whole component and can differ considerably from a...

Zusammenfassung:In the early-damage regime of rails subjected to rolling contact fatigue, the material undergoes severe plastic deformation forming a modified sub-surface microstructure. This zone close to the surface determines subsequent fatigue properties of the whole component and can differ considerably from an initial microstructure of the same material. Therefore, a fundamental understanding of early damage phenomena (
