Abstract

High-strength bainitic cast iron is studied after isothermal hardening at 340°C for from 0.5 to 5 h with the use of a non-destructive eddy-current method for monitoring the microstructure and mechanical properties. Iron microstructure is studied by optical microscopy and x-ray diffraction analysis. Brinell hardness and the impact energy are determined. Correlation is established between electromagnetic sensor signal, microstructure, and mechanical properties. It is shown that induced voltage and normalized impedance may be used for non-destructive monitoring of the production process and cast iron quality.
