Residual Stresses in Railway Axles

Abstract. The companies producing railway axles are obliged to demonstrate a level of residual stresses in their products based on the specification of standard EN 13261 in which the applicable methods are suggested and the allowable values of residual stresses are specified. An objective of this contribution is to arouse a discussion whether the requirements of the standard can be met by means of the suggested measuring methods – hole-drilling (according to ASTM E837-13 standard) or X-ray diffraction. It especially applies to the ability to determine the residual stress distribution in the depth of 2 mm below the surface. The mentioned issue is demonstrated by means of both measuring methods under various measurement conditions.
