The paper presents the investigations conducted in the Fraunhofer Institute (IZFP Saarbrucken) by use of a BEMI microscope (BEMI= Barkhausenrausch- und Wirbelstrom-Mikroskopie or Barkhausen Noise and Eddy Current Microscopy). The ability to detect cyclic and contact fatigue load influences has been investigated. The measurement amplitudes obtained with Barkhausen Noise and Eddy Current probes have been analysed. Correlation of measurement results and material's condition has been observed in case of the eddy current mode method for frequencies above 2 MHz (for contact-loaded material samples). Detection of material's fatigue process (at 80 % fatigue life) in the sample subjected to series of high-cyclic loads has been proven to be practical...
