Abstract EN
An experimental investigation was carried out to study the effect of variation in Barkhausen noise (BN) analysis parameters (magnetizing voltage and excitation frequency) for assessment of microhardness profile upon surface grinding.
A varying amount of surface damage was induced in the ground samples by changing the downfeed during grinding.
It was observed that variation in microhardness inversely affects root mean square (rms) value of BN signal.
The observed BN profile indicated no phase transformation or microstructural changes upon grinding.
Metallographic study of ground samples has been undertaken to confirm the results obtained by BN analysis.
Barkhausen noise parameter (rms value of BN signal), at elevated magnetizing voltage and excitation frequency, increased with reduction in microhardness along the depth indicating the applicability of BN analysis technique in assessing the microhardness profile of ground steel.
