Xrd Method

The use of magnetic Barkhausen noise (MBN) signal to non-destructively characterize the in-depth residual stress state of machined steel was investigated. The effect of the frequency of the magnetic field applied and of analysing the resulting MBN signal in different frequency bands for an in-depth residual stress characterisation is discussed. The effect of the residual stress on each of the parameters derived from the MBN signal is analysed comparing with the result of the XRD method.

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.

The Relationship

The Magnetic Barkhausen Noise (MBN) technique can evaluate the residual stresses in carbon steel and provide information about the relationship between residual stress level and MBN signal. This research work is based on the analysis of MBN signals obtained from carbon steel samples. ASTM A36 and A516 carbon steel were used to vary the residual stress by heat treatment process with 5 conditions: annealing, normalizing, quenching in oil, quenching in water and quenching in salt water. The microstructure and hardness of samples also were varied by these heat treatment processes. Twelve samples (including base materials) were cut to analyze the microstructure and hardness by the microscope and hardness testing machine. Reference materials from each condition were established to represent the MBN signals. The MBN technique was used to evaluate the residual stresses from heat treatment process on each reference material. Then each sample was prepared to tensile specimen. All specimens were applied static tension load below yield point. The load was increased at 25 N/mm2 (MPa) in increment. Each tensile stress level was measurement by MBN technique at 0 and 90 degree of direction of tension axis. The experimental results found that the MBN signal amplitude changed as the condition of heat treatment changed and the relationship between tensile stress and MBN signal showed linear correlation. This research is useful to understand and guide for establishing the reference materials for residual stress measurement by MBN technique.

Magnetic Barkhausen noise (MBN) is a new technique on non-destructive testing of residual stress. The testing system based on virtual instrument was explored. It can achieve the MBN and deal with it in time. The technique is applied to analyze residual stress in the welding line of iron materials back and forth the heat treatment. Through comparing with the data of blind-hole method, the corresponding change between Barkhausen signals and residual stress is verified.
