MEASUREMENT OF RESIDUAL STRESSES IN RAILWAY RAILS MADE FROM HIGH-CARBON STEEL BY A NONDESTRUCTIVE METHOD (EXCHANGE OF EXPERIENCE)

This very brief article essentially cites two systems for determining the residual stresses in rail which the authors have investigated: one is based on measuring the anisotropy of the magnetic permeability, and the other on measuring the effective values of the magnetic permeability using the high harmonics of the emf's from the signal of a pickup. In both cases superposed pickups are used. The measurement results obtained with the magnetic transducers are compared with those obtained with a strain gauge using a cutout template. Two figures show the distributions of residual stresses at the center of the testpiece cross section, as obtained with both transducers, and compare them with those obtained by the strain-gauge measurement.
