“…This correspondence shows that the coercive field and UTS are well correlated. This important correlation between mechanical properties and magnetic properties needs to be further investigated since it is known that neutron irradiation changes both the magnetic [29] and mechanical properties of this steel.…”

“…Therefore, the saturation magnetization decreases as more and more FeB and Fe 2 B phases are introduced with increasing boronizing time. In a low alloy steel, Park et al [13] showed that the increase of saturation magnetization is due to Fe atoms being separated from Fe 3 C carbide after neutron irradiation. In this study the decrease in saturation magnetization is attributed to the formation of the FeB and Fe 2 B phases.…”

“…It has been shown that the change in magnetic parameters of irradiated steel depends on various conditions: specimen preparation, irradiation conditions, residual stress and microstructural differences [12,13]. The effect of these parameters on saturation magnetization is the subject of controversy [14].…”

The change of saturation magnetization in boronized low carbon microalloyed steels was investigated as a function of boronizing time. Specimens were boronized in an electrical resistance furnace for times ranging from 3 to 9 h at 1123 K. The metallurgical and magnetic properties of the specimens were investigated using optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD) and vibrating sample magnetometry (VSM). A boride layer with saw-tooth morphology consisting of FeB and Fe 2 B was observed on the surface, its thickness ranged from 63 µm to 140 µm depending on the boronizing time. XRD confirmed the presence of Fe 2 B and FeB on the surface. The saturation magnetization decreased with increasing boronizing time. This decrease was attributed to the increased thickness of the FeB and Fe 2 B phases. Cracks were observed at the FeB/Fe 2 B interfaces of the samples. The number of interfacial cracks increased with increasing boronizing time.

“…While it has been frequently shown that mechanical changes in steels, such as those resulting from neutron irradiation, have effects on the major loops of magnetization (e.g., Park et al 2004a;Park et al 1997a)), Barkhausen noise (e.g., (Chang et al 2002;Altpeter et al 2001;Park et al 1999d;Park et al 1999b;Sipahi et al 1994)), impedance spectroscopy (Park et al 2004b;Park et al 2004a), and ferromagnetic resonance (Park et al 2004b;Park et al 2003), only one group has looked at the effects of mechanical changes and precipitation on minor hysteresis loops where the magnetic history is not merely between positive and negative saturations Kobayashi et al 2009Kobayashi et al , 2008Takahashi et al 2005). First order reversal curves (FORCs) are similar to minor loops but consist of only part of the loop.…”
