Barkhausen Effect in Dual Phase Steels

    Graphical Abstract
    • Abstract
  • The present paper describes the charecteristics of Barkhausen noise and magnetomechanical acoustic emission in ferrite-martensite dualphase steels during Barkhausen jumps, and the influence of mic-rostrcture, stress and strain on a magnetic and acoustic Barkhausen signal.The results show that Barkhausen noise(BN) in dual phase steels strengthen with the increase of the pulling stress,and that weaken with the decrease of comprassive stress.The relationship between Barkhausen signal and the mechanism of deformation in materials is discussed.
