Application Status of the Barkhausen Effect in Nondestructive Testing
Abstract: Change of internal
structure or internal defect in ferromagnetic materials can produce change in
Barkhausen noise, and by using Barkhausen noise signal measurement, the quality
and internal defects of the material can be judged. The nondestructive testing
technology is based on the Barkhausen effect, it gets the attention because of
its advantages, such as rapid, non-destructive, mensurable, mainly used to
detect stress, hardness, grain size, grinding burn etc.. The research status of
Barkhausen effect in nondestructive testing was reviewed. Its application
situation was investigated that the nondestructive testing technology based on
the Barkhausen effect on stress, hardness, grain size, grinding burn detection
etc., and the relationship between the MBN signals and stress, hardness, grain
size, grinding burn were showed.
