Resumo(s)
Rolling contact fatigue twin-disc tests were performed on rail/wheel steels from Spanish
high velocity trains (AVE). Residual stress profiles were determined using X-ray diffraction before
and after cyclic loading. The evolution of residual stress profiles, due to cyclic loading, was
analysed in order to study how they affect the rolling contact fatigue behaviour of these materials.
This study is included in a major project where other related phenomena and materials’ properties
have been studied.
