title = "Evaluation of rolling contact fatigue of rail materials in twin disc tests",
abstract = "Rolling Contact Fatigue (RCF) is a common failure mechanism in rails. Accelerated RCF tests were carried out on five rail materials. The aim was to evaluate the wear rates, and the depth and mean spacing between RCF cracks. Thickness and maximum hardness of surface layers were measured using micro-indentation. The results showed that for hard rails the wear rates are lower. For the pearlitic materials (R260, R350HT, and R400HT), there is a correlation between thickness of deformed layers and mass losses. Cracks were shallower for R400HT and deepest for standard rail material. Hardened rails had lower mean spacing between cracks.",
