Jeffrey s Ceurter (*)

Barkhausen noise is created on the abrupt changes in the magnetization of materials beneath an applied alternating current. These changes are known to be affected by means of microstructure and the presence and distribution of elastic stresse In the case of grinding damage, the two residual stress and microstructural changes may be bring to lighted

In this article, the theory of Barkhausen noise is reviewed, with a focus upon the application of nondestructive testing for grinding damage upon ferromagnetic materials. The theory of grinding is discussed with relate to to microstructural and residual stres changes, and examples are given to present to view how Barkhausen ...
