... and production of rail steel are discussed, including: impact of steel chemistry on the phase diagram, effect of thermomechanical processing on microstructure, and in uence of microstructure or residual stress on mechanical properties. KEYWORDS: accelerated cooling, rail steel, pearlitic steel, quenching...

...J. Toribio; B. González; J. C. Matos; F. J. Ayaso This paper deals with the influence of the manufacturing process on the fatigue behavior of pearlitic steels with different degrees of cold drawing. The fatigue crack growth rate (d a /d N ) is related to the stress intensity range (Δ K ) by means...
