The objective of this work is to investigate the microstructure evolution railway pearlitic wheel materials (ER7, CL60 and C-class) under a rolling-sliding contact loading. Firstly, microstructures steel at different depths from strain-free matrix top surface were systematically investigated via laser scanning confocal microscope (LSCM), electron microscopy (SEM), backscattered diffraction (EBS...

The relevance of this work stems from the urgent need for modern development Ukrainian railway transport and acceleration Ukraine's integration into European transportation. Currently, most effective way to travel across borders between countries with different track gauges is use gauge-changeable wheelsets, a system that can change one gauge another when moving through special changing facilit...
