“…The initiation and evolution of wheel-rail RCF is also affected by the material microstructures, as for instance, RCF cracks are primarily initiated at the highly strained ferrite phase and propagated along grain boundaries by cavitation [15,16]. Moreover, varying work hardening levels were found on the pearlitic and bainitic rail materials [17][18][19]. The work hardening changed the H w /H r during the test, further affecting the wear and RCF behaviours.…”

“…In industrial processes like laser or electron beam welding, laser flash hardening, adiabatic shearing and in operating environments such as wheel-rail contact in railway traffic, the material is sometimes subjected to rapid heating and cooling within a localised volume [1][2][3][4][5][6]. Such local heating often has a short duration and is normally followed by self-cooling with large cooling rates.…”
