Description

This paper is concerned with recent investigations of the effects of both microstructure and stress on the magnetic properties of steels. In particular the paper focuses on how the changes in material condition due to differences in microstructure and stress lead to changes in magnetic NDE measurements using techniques such as Barkhausen effect sensors, magneto acoustic emission sensors, hysteresis and the magnetoelastic (magnetically induced velocity change) method.
