Abstract

The velocity of Rayleigh waves is correlated with the depth of the decarburized layer and the hardness of rail steel. With increase in the depth of the decarburized layer and decrease in the hardness, the velocity of Rayleigh waves increases. Conversely, in the same conditions, the coercive force of the rail steel declines. The thickness of the decarburized layer is determined by this method and confirmed by direct measurements.
