چکیده
The present research investigates improvement of Eddy Current (EC) technique as a
nondestructive method for measurement of ductile cast iron microstructural and mechanical
characteristics. Six samples of heat treated ductile cast iron have been selected to study the
relations between pearlite content and EC outputs. These outputs include voltage and normalized
impedance as well as calculated parameters of harmonic analysis. Furthermore, correlation
between mechanical properties such as hardness, yield strength and ultimate tensile strength in
samples containing different ferrite-pearlite matrices and the magnetic responses has also been
found. High correlation coefficients of the relations indicate an acceptable level of accuracy in
comparison with destructive method.
