A yoke probe, which has a winding coil for excitation, a pickup coil to detect magnetic flux and a U-shaped magnetic single-yoke, has developed and examined to evaluate the magnetic property like coercive force using the probe without machining of specimens. Ac permeability was also evaluated indirectly by means of impedance measurement with the proposed probe. Then measured magnetic parameters were correlated with mechanical parameter like Vickers hardness. Additionally the impedance distribution of the deformed steels was evaluated. Impedance distribution will reflect the distribution of mechanical properties of the deformed steels. Our trail for NDE of degradation of materials using magnetic single-yoke probe is introduced and its potential is discussed.
