Tensile stress effect on magnetic Barkhausen noise of silicon steel single crystal (measurements and simulations)

Résumé

The Magnetic Barkhausen Noise (MBN) measurement can be used to evaluate non-destructively mechanical internal stress in electrical steel laminations. However, such evaluation is complex as various factors can distort the MBN signal similarly. Internal stress is one of them, but an increase in dislocation density or other defects can be just as influential. This work focuses on single crystals with pre-determined crystallographic orientation to isolate basic mechanisms. The reconstructed MBN energy hysteresis cycles are compared to classical hysteresis loops, and to simulation obtained from a multiscale model. These comparisons provide new insights into the impact of tensile stress on the magnetization process and the magnetic domains kinetics and bring perspectives regarding the ideal way to perform MBN non-destructive evaluation of internal mechanical stress.
