“…The dislocations are distributed uniformly at the beginning of the plastic stage and the dislocation density is small. With further tension, the dislocation density increases and dislocations become distributed heterogeneously . Afterwards, dislocation tangles, dislocation walls and dislocations pile up at the vicinity of grain boundaries form the regions of high dislocation density.…”

“…K. I. Yamamoto et al investigated the magnetization changes due to stress change in a constant magnetic field on amorphous ribbons and found that the magnetization change due to stress was divided into reversible and irreversible components. J. Pal'a et al used two magnetic methods (hysteresis and Barkhausen noise emission) to study the degradation of a low‐carbon steel with plastic tension after unloading and observed the dislocation structure formation by transmission electron microscopy. However, most studies monitored the magnetic responses under the excitation of external magnetic field and little effort was made to relate the magnetic characteristics with different loading stages.…”

The purpose of this paper is to explore the correlation between the mechanical actions and the piezomagnetic field variations of ferromagnetic steels. The continuous examination of changes in the piezomagnetic behaviour was performed during tensile tests of Q235 and Q345 steels. The results obtained allowed the division of the magnetic behaviour of the investigated steels into four stages corresponding to four distinct loading stages. The piezomangtic fields demonstrate apparently different variation characteristics in different loading stages. Furthermore, the field intensity firstly reaches its extremum before the yield point. The variation of the ratio between the stress of the extreme point and the yield strength shows regular changes. The characteristics of the piezomagnetic responses are discussed in terms of the mechanical and microstructural condition of the steel. Additionally, a comparison of the piezomagnetic field variations in Q235 and Q345 steels demonstrates that the piezomagnetic properties are unique attributes of the material, which may result from the different chemical composition and microstructure of the two steels.

“…Due to the microstructural dependence of the magnetic response, the magnetomechanical effect has recently been receiving increasing attention particularly from those interested in applying it to the condition monitoring of steel structures by magnetic measurement. Pal'a et al used the magnetic methods of piezomagnetic hysteresis and Barkhausen noise emission to study the degradation of a low‐carbon steel with plastic tension after unloading and observed the dislocation structure formation by transmission electron microscopy. Huang et al studied the quantitative relationships between the surface residual magnetic field and cyclic stress with applied magnetic field.…”

The objective of this research is to explore the correlation between uniaxial ratcheting behaviour and magnetic response under asymmetrical cyclic stressing in X80 pipeline steel. The magnetic field variations from cycle to cycle were recorded simultaneously during ratcheting. Analysis made in the present work shows that the magnetic hysteresis loop evolves systematically with the number of cycles in terms of its shape and position. The most prominent result here is that the magnetic field under a certain stress first decreases sharply in the preliminary stage of ratcheting, followed by a stable decreasing period with an approximately linear slope. Furthermore, it can be concluded that ratcheting influences the changes in magnetic field more significantly under tensile stress than compressive stress. The underlying reason of the strong non‐linearity of the magnetic field evolution was discussed.
