Abstract Scope Railway crossings are one of the most important elements of the railway infrastructure. They are subjected to severe impact fatigue loading that causes degradation or failure of crossings. Damage in complex multiphase steels such as bainitic steels for crossings application is strongly affected by their microstructure. Understanding of damage in relation to the microstructure in these steels can provide guidelines for better design. In this study, we focus on damage in low carbon carbide free bainitic steels produced by continuous cooling transformation. Their complex heterogeneous microstructure can lead to strong strain partitioning among the microstructural constituents such as martensite, bainitic ferrite and retained austenite providing weak links for the crack initiation and propagation. In this study, we demonstrate the in situ strain partitioning and damage in carbide free bainitic steels using micro-digital image correlation in Scanning Electron Microscope (SEM) in combination with Electron Back Scatter Diffraction (EBSD).
