11. Anisotropy in pearlitic steel subjected to rolling contact fatigue - modelling and experiments
Abstract : In rails and wheels subjected to severe rolling/sliding contact, large plastic deformations accumulate in the surface layer. This decreases the fatigue resistance of components and makes this layer prone to formation of common rolling contact related defects. READ MORE

12. On multiscale modeling of pearlitic steel
Abstract : By studying pearlitic steels using a scanning electron microscope it can be observed that pearlite is a two-phase material with cementite lamellae embedded in a matrix of ferrite. The cementite is commonly described as being stiff and brittle in comparison to the ferrite which is considered to have a soft and ductile mechanical behavior. READ MORE
