In the previous study, we proposed an eddy current magnetic signature method as a way to evaluate the residual strain of low carbon steels. However, the dependence of the pearlite content which affects magnetic properties of steel on the eddy current magnetic signature has not been discussed yet. In this study, to evaluate the effect of the pearlite content on the eddy current magnetic signature, two kinds of low carbon steels with different pearlite contents are investigated. The specimens with different r...

Evaluation of residual strain of low carbon steels with various pearlite contents by eddy current magnetic signature method

This study aims at proposing a novel magnetic testing method, eddy current magnetic signature method for evaluation of residual strain in carbon steels. This method characterize the eddy current magnetic signatures that is eddy current signals in an impedance plain during magnetization process. In order to discuss the feasibility of this method, eddy current magnetic signatures of a set of tensile test specimens are investigated. The relationship between eddy current signature and plastic deformation is di...
