Management of the residual stress state has critical importance for fatigue life of the carburized steel components. The conventional methods of residual stress measurement are either destructive or have limited ability for in-situ measurement or take considerable time. Hence, there is a need for rapid, practical and reliable non-destructive method for measurement of residual stress. The aim of this study is to investigate the efficiency of the magnetic Barkhausen noise (MBN) method for evaluation of the surface residual stresses in the carburized SAE 8620 steel. Various samples having different residual stress states were prepared by changing carburization time at 900oC. The results of MBN measurements were compared with those of the X-ray diffraction method.
