چکیده: Eddy current and Barkhausen noise nondestructive testing techniques were considered to evaluate the magnetic properties of the decarburised steels as a function of microstructure. To make changes
in decarburising depth, carbon steel samples were austenitised at 890 °C for 120–270 min. Considering different decarburised depths, height, position and width of the noise profiles were extracted in
order to analyse the magnetic Barkhausen noise measurements. Next, the eddy current test was performed to detect the changes in the microstructure through decarburising of the steel taking into
account the impedance variations. According to the results, both techniques allow us to detect changes in the magnetic properties of the decarburised steels and link them with their microstructural
changes, nondestructively.
