Abstract

Experiments have been carried out using yoke for energizing alternating magnetic field in the steel samples. We used acoustic emission sensors and ultrasound microphone for recording acoustic signal born in the steel material. Results of experiments clearly show the presence of Acoustic Barkhausen noise. We are introducing graphs presenting dependence of acoustic time response signal on magnetic signal (inductance) in form of Lissajous curve. It is claimed that this new method gives more in-sigh in the material than the widely used simple RMS measurement of acoustic response.
