Abstract
A multifrequency electromagnetic sensor was used to measure decarburization in steel. Decarburization samples were generated by heat treating Fe-0.8 wt.% C steel rods for various times in air at 1000 °C. The inductance value of the sensor at different frequencies varied as a function of decarburization depth due to the difference in magnetic permeability between ferrite and pearlite. The relationship between sensor output and decarburized layer thickness was modelled using finite element software. © 2008 Acta Materialia Inc.
