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 degrees 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. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
