Correlation between Barkhausen Noise and plastic deformation in TRIP 800 steel specimens

摘要

The aim of this study is to contribute to a better understanding of the dependence between Magnetic Barkhausen Noise and the plastic deformation of TRIP 800 steel samples. The TRIP 800 steel samples were subjected to increasing deformation by means of tensile loading and, meanwhile, Magnetic Barkhausen Noise parameters were measured (online measurements). Magnetic Barkhausen Noise parameters were, also, measured after the tensile deformation (offline measurements). The microstructure of the samples was studied by using Scanning Electron Microscopy and, finally, micro hardness and macro hardness measurements took place.
