Industry has been searching for ways to measure residual stresses accurately, quickly and easily without damage to the material being tested. Several methods have been developed; however, these are either destructive or of limited capability. A less conventional approach, the magnetic Barkhausen noise (MBN) method, is of particular interest because of its potential as a non-destructive industrial tool to measure residual stress and other microstructural parameters. The purpose of this study is evaluation of the relation between residual stress and magnetic Barkhausen noise in Fe360 Steel specimens. A MBN-stress calibration set-up was developed. To control the accuracy and the effectiveness of the developed system and procedure, various MBN measurements were carried out; hardness measurements were also conducted.
