The effect of compressive plastic deformation on the magnetic properties of AISI 4130 steels with various microstructures
TLDR
The magnetic properties of AISI 4130 steel after eight heat treatments have been investigated as discussed by the authors, and properties such as hysteresis loss, coercivity and initial permeability were found to be closely interrelated.Abstract:
The magnetic properties of AISI 4130 steel after eight heat treatments have been investigated. Properties such as hysteresis loss, coercivity, and initial permeability were found to be closely interrelated. Furthermore, they were each dependent on the hardness of the material. A relationship between the hardness and permeability was found which was microstructure independent. These parameters were also found to change in a systematic way with plastic deformation and this result can be used for non-destructive evaluation. Correlations between the magnetic parameters were also found to change in a systematic way with plastic deformation and this result can be used for non-destructive evaluation. Correlations between the magnetic parameters revealed relationships which depended on the microstructure of the material. The residual stress in steels can be determined from the changes in maximum differential permeability.read more

Effect of different stages of tensile deformation on magnetic barkhausen emission in high strength low alloy steel
TL;DR: In this paper, the effect of tensile deformation on micromagnetic parameters has been studied by many researchers, and most of these studies have been done only in the elastic region and the obtained relation between magnetic parameters and the applied stress has been used to determine the residual stresses, considering that the residual stress level will not exceed the yield stress of the material.

Theory of ferromagnetic hysteresis
David Jiles,David L. Atherton +1 more
TL;DR: In this paper, a mathematical model of the hysteresis mechanisms in ferromagnets is presented based on existing ideas of domain wall motion including both bending and translation, which gives rise to a frictional force opposing the movement of domain walls.

TL;DR: A theory of the magnetisation process in ferromagnets, based on existing ideas of domain rotation and domain wall motion is presented in this article, which has been developed via a consideration of the various energy terms into a mathematical description leading to an equation of state for a ferromagnet.

Model for the effect of tensile and compressive stress on ferromagnetic hysteresis
TL;DR: In this article, a model for the stress-dependent effective field was presented, which when used in conjunction with the Jiles-Atherton theory, qualitatively accounts for the change in slope and shape of the hysteresis curves with uniaxial stress and convexity of the curves depicting remanent and peak magnetization as a function of stress.
