ABSTRACT
Investigation of fatigue processes on the basis of domain structure imaging makes possible identification of material zones and fatigue degree and will permit the introduction of changes in the wheel construction at the design stage. Investigation results of domain structure of wheelset’s rolling surface subjected to contact loads and material samples subjected to cyclic loads have been presented in this paper.
