Surface Residual Stresses

Management of the residual stress state is vital for the design and production stages of carburised components in order to satisfy the technical requirements related to performance, fatigue behaviour and useful lifetime. This enforces the use of practical, reliable and time- and cost-effective stress measurement methods by manufacturers. This study aims to investigate the efficiency of the magnetic Barkhausen noise (MBN) method in rapid non-destructive determination of surface residual stresses in carburised steels. A series of AISI 8620 steel specimens with different residual stress states was prepared by altering the carburising and subsequent tempering parameters. The specimens were characterised through scanning electron microscopy (SEM) investigations and hardness measurements, and the surface residual stresses were determined using both the MBN and X-ray diffraction (XRD) methods. The results show that a good correlation exists between surface residual stress and the parameters derived from the MBN signals.

Railway Wheels

Residual stresses on the surface of disks of one-piece-rolled steel railway wheels, caused by their fi nishing (turning) with different tool feed rate and speed, are measured using the X-ray diffractometric method implemented using the DRP portable diffractometer. It is shown that the specifi ed fi nishing parameters have signifi cant infl uence on the level of surface residual stresses induced by fi nishing. The most favorable stress state (compressive stresses up to –200 MPa) on the surface of the disks is achieved under relatively small values of tool feed and speed. The results may serve as basis for improving of the fi nishing technology of solid-rolled wheels.

ABSTRACTEnergy-dispersive neutron diffraction has been developed at the NIST reactor as a probe of sub- and near-surface residual stresses in technological samples. Application of the technique has been made to a variety of metallurgical specimens which includes the determination of tri-axial stresses as a function of depth in a number of uranium-3/4wt%Ti samples with different thermo-mechanical histories, and in two types of 7075-T6 aluminum “ogives”- of interest to the Army. Preliminary results have been obtained for an induction-hardened steel shaft, a fatigue lifetime test specimen for the SAE.
