Six samples of heat treated ductile cast iron have been selected to study the<br />relations between pearlite content and EC outputs. These outputs include voltage and normalized<br />impedance as well as calculated parameters of harmonic analysis. Furthermore, correlation<br />between mechanical properties such as hardness, yield strength and ultimate tensile strength in<br />samples containing different ferrite-pearlite matrices and the magnetic responses has also been<br />found. High correlation coefficients of the relations indicate an acceptable level of accuracy in<br />comparison with destructive method.
