Non-Destructive Testing Device for Hot Forming High Strength Steel Parts Based on Barkhausen Noise

Abstract:

In order to realize the nondestructive testing for hot forming high strength steel parts, a hardness testing device based on Magnetic Barkhausen Noise (MBN) was developed. By measuring MBN of standardized blocks of Rockwell hardness and extracting feature values of the noise, a fitted curve between hardness and MBN peak was calibrated. Good linearity was found between hardness and MBN peak within high hardness range 35~60HRC. The testing device was proved to be high-precision and stable by measuring the practical high strength steel parts.
