Measurement of residual stresses in the carburized steels by non destructive techniques

2016-10-01
Residual stress state on the surface layers has a critical effect on the service performance and fatigue life of the carburized components. Non-destructive determination of residual stress state in a rapid and reliable way has being gained importance for industrial applications. The aim of this study is to investigate the efficiency of the magnetic Barkhausen noise (MBN) method for monitoring the residual stress variations as a function of carburizing process parameters. For this purpose, MBN and XRD measurements were performed on a series of samples prepared by changing process parameters, and then, the results were compared and discussed.

Review of Residual Stress Measurement by Magnetic Barkhausen Noise Technique
Gür, Cemil Hakan (2018-01-01)
Determination of residual stress state is important for quality, integrity, and service performance of the components and structures. Almost all manufacturing processes cause considerable amounts of residual stress; thus, any process or product design ignoring it involves a risk for distortion or early failure. Among the existing methods, the magnetic Barkhausen noise method has been gaining attention for measuring residual stresses nondestructively in ferromagnetic materials. It is sensitive to the interac...
Monitoring variation of surface residual stresses in shot peened steel components by the magnetic Barkhausen noise method
SAVAŞ, SERDAR; Gür, Cemil Hakan (2010-12-01)
Shot peening is a cold working process by which residual compressive stresses are induced in the surface and near-surface region to increase the fatigue strength and the resistance to stress corrosion cracking This study covers non-destructive evaluation of surface residual stresses in the shot peened steel components by the magnetic Barkhausen noise method For this purpose various sets of steel specimens were prepared by a controlled shot peening process with different intensities impact angles and coverag...
