... Abstract Gears are a common part type for applications of the magnetic Barkhausen noise (MBN) techniques for nondestructive inspection. This article discusses the typical applications for MBN techniques, namely, detection of grinding retemper burn, evaluation of residual stresses, and detection...

... trepanning the part. The nonlinear elastic methods, including Barkhausen noise, eddy current, and ultrasonic, rely on higher-order effects of stress on the magnetic, electrical, or acoustical properties of the part. If the part is not externally constrained, then the residual-stress distribution must be...

... properties characterization methods rely on bulk measurements of the hysteretic properties of material magnetization or of some related phenomenon, such as Barkhausen noise. The flux leakage method also is used to inspect steel reinforcement in concrete beams. The basic function of the magnetic field...
