When grinding hardened steel there is always the possibility for surface damage in the form of residual stress and microstructural changes. Methods for detecting this sort of damage may have drawbacks, such as production time, complexity, subjectivity and use of hazardous chemicals. The authors present a relatively new method, known as the Barkhausen noise analysis, that may meet the demand for measuring defects in ground steels.
