Numerical determination of hysteresis parameters for the modeling of magnetic properties using the theory of ferromagnetic hysteresis
TL;DR: In this article, various model parameters needed to describe hysteresis on the basis of the Jiles-Atherton theory can be calculated from experimental measurements of the coercivity, remanence, saturation magnetization, initial anhysteretic susceptibility, initial normal susceptibility, and maximum differential susceptibility.

Nondestructive evaluation of creep damage in power-plant steam generators and piping by magnetic measurements
TL;DR: In this paper, the authors used magnetic hysteresis measurements to evaluate creep damage in power plant weldments and found that during high temperature creep there is a significant change in microstructure such as the formation of voids, dislocation networks and grain boundary cavities.

Recent developments in modeling of the stress derivative of magnetization in ferromagnetic materials
David Jiles,M.K. Devine +1 more
TL;DR: The effect of changing stress on the magnetization of ferromagnetic materials leads to behavior in which magnetization may increase, or decrease, when exposed to the same stress under the same external conditions as discussed by the authors.

Magnescope: A poratble magnetic inspection system for evaluation of steel structures and components
TL;DR: In this article, a portable magnetic inspection device was developed for nondestructive evaluation of ferromagnetic steel structures and components, consisting of an inspection head, instrumentation for measuring magnetic-field and flux density, and a computer together with the necessary control and data analysis software.

Detection of fatigue in structural steels by magnetic property measurements
TL;DR: In this article, magnetic hysteresis measurements have been used to monitor the changes in the parameters due to low cycle fatigue, with the overall objective of developing a new tool to enhance the present NDE techniques for detecting failure.
