Evaluation of Railway Rails Suffered from Rolling Contact Fatigue Using X-Ray Generalized cosα Method

Abstract:

In this study, the diffraction rings were measured point by point all over the head of rail sample which was used in service, and shearing stresses with respect to the depth direction were determined using the generalized cosα method. The full width at half maximum was also estimated from the diffraction ring.
