Experimental Study on the Stress of Ferromagnetic Tensile Specimen Using Magnetic Barkhausen Noise Detection

Article Preview

Abstract:

This paper describes a newly developed set of Barkhausen noise testing system including magnetizing and pick-up coils and the subsequent data acquisition unit based on the generation mechanism of Barkhausen noise. We studied the intensity of magnetic Barkhausen noise (MBN) of 16MnR steel under different states of stress by tensile test of flat-shaped specimens.
