Validation of Stress and Hardness Determination by a New NDT Method
Using the reference techniques of neutron diffraction, mechanical hardness test and magnetic hysteresis measurement the new non-destructive testing (NDT) approach for residual stress, hardness and coercive field determination by Barkhausen noise amplitude as a function of the strength of magnetizing field will be validated. For that purpose, it is planned to consider different industrial components: steel plate with a welding seam, formed automotive component and reactor pressure vessel surveillance specimens reconstituted by Beam Welding methods. A positive validation for that examples would have a big impact for further applications of the described Barkhausen noise method since the reliability of the obtained NDT data will significantly increase.
