The paper analyses fatigue crack closure in the near-threshold regime of the EA4T railway axle steel. The dependence of fatigue crack growth threshold on air humidity was experimentally obtained. Varying air humidity led to changes of fatigue thresho

Residual stresses play an important role in propagation of potential fatigue cracks and they influence residual fatigue lifetime of railway axles. Essential step for assessment of residual fatigue lifetimes of railway axles is determination of magnit

Assessment of residual fatigue life of railway axles commonly does not include effect of residual stress. This paper presents advanced methodology for estimation of residual fatigue life of railway axles considering not only external loading but also

The railway axles are subjected to cyclic loading during their operation. Their load is of long-term nature, therefore a real risk of fatigue failure exists. This failure could lead to derailment of the whole train with serious consequences. To preve

The operation of railway axles should fulfill at least two main demands: safety and low operation costs. A significant part of operation costs is given by the length of regular inspection intervals which should reveal potential fatigue cracks in rail

The main aim of the presented paper is to show how heat treatment, in our case the induction hardening, will affect the wear rates as well as the ratcheting evolution process beneath the contact surface in the field of line rolling contact. Used wear

One of the most loaded components of the train, with very long operation time, is a railway axle. During its operation, the conventional fatigue limit of 107 cycles is reached easily and information about fatigue behavior for a higher number of cycle
