Statistical Evaluation of Barkhausen Noise Testing (BNT) for Ground Samples [PDF]

Sensors, 2019
Barkhausen noise testing (BNT) is a nondestructive method for investigating many properties of ferromagnetic materials. The most common application is the monitoring of grinding burns caused by introducing locally high temperatures while grinding. Other features, such as microstructure, residual stress changes, hardening depth, and so forth, can be ...
