X-ray Fourier Analysis on Rolling Contact Fatigue Layer Formed in Rail

The crystallite size and dislocation density in RCF (rolling contact fatigue) affected layers have been identified using X-ray Fourier analyses on serviced rails. The evaluation of the crystallite size and dislocation density is based on modified Williamson-Hall and Warren-Averbach models. This evaluation enables quantification of the microstructure evolution in the...
