Simulation of Alloy Content Assessment in Fe-Si Alloy Steel by Eddy Current Testing

摘要：

　　The present study,which is based on the finite element method,investigates the alloy element content assessment of these Fe-Si alloy steel sheets from the view point of eddy current testing.The relative permeability and conductivity were preset parameters.Eddy current signals were gathered by a differential type cylindrical probe and subsequent nondestructive tests were carried out with the preparation of four Fe-Si alloy steel sheets with different silicon contents.The result of the numerical simulation demonstrated that the signal increased with the increase of the silicon content in the Si-Fe alloy steel sheets.And the measured result confirmed the rationality of the application of eddy current testing in the average silicon content assessment.
