Résumé :

Inspection by eddy current is one of techniquesthat are very used in nondestructive evaluation of materials. Theobject of this work is to carry out an analysis of the residualstresses in the material created by external solicitations andanalyses by eddy currents as a non destructive testing method.The analysis of the eddy current results will be compared to theresults obtained by the traditional methods (X-rays diffraction…)in order to determine a relation between the non-destructive testsand destructive. It was shown in this work that all microstructuremodifications of the samples were detected and they can bequantified by eddy current impedance measurement. Theimpedance analysis by eddy current will be correlated with themicrostructure changes observed in the material because ofplastic damage and fatigue.
