Monitoring of Plastic Straining Degree of Components Made of Interstitial Free Steel after Uniaxial Tensile Test by the Use of Barkhausen Noise Technique

Abstract

In article 2100597, Neslušan and co-workers demonstrate the usability of the magnetic Barkhausen noise (MBN) technique for monitoring the critical state of plastic straining in the case of interstitial free (IF) steel used in automotive body parts. They are alerting of rupture during forming when MBN grows in the direction of load (TD) at the expense of the perpendicular direction (RD). The remarkable drop of MBN envelope width and the shift of MBN envelope above the critical threshold also alert incoming rupture.
