Modeling of the Barkhausen jump in low carbon steel
TL;DR: In this paper, a model for the magnetic Barkhausen jump in low carbon content steels is presented, and the results of the model are used to deduce the influence of the microstructural features and of the magnetizing parameters on the amplitude and duration of the Barkhaen jumps.
Journal ArticleDOI
Effect of the demagnetisation factor on the Barkhausen noise signal
TL;DR: In this paper, a splitting of the magnetic Barkhausen noise (MBN) signal distribution was observed in the form of two peaks during a slowly varying magnetisation sweep through specimens of an alloy steel.

Monitoring the Microstructural Evolution in Spheroidized Steels by Magnetic Barkhausen Noise Measurements
Kemal Davut,Cemil Hakan Gür +1 more
TL;DR: In this article, the authors monitor the degree of spheroidization in steels by Magnetic Barkhausen Noise (MBN) method and show that MBN signals are very sensitive to the variations in the microstructure caused by the heat treatment.

The acoustic emission along the hysteresis loop of various ferro and ferrimagnets
Marcel Guyot,V. Cagan +1 more
TL;DR: In this article, a general quantitative original law is established from measurements on series of polycrystalline ferrimagnets: the acoustic emission activity is proportional to the hysteresis losses, whatever the grain size, the composition or the measuring temperature are.
Journal ArticleDOI
The influence of controlled rolling on the pulse height distribution of magnetic Barkhausen noise in steel
TL;DR: In this paper, the influence of furnace cooling, normalizing and controlled rolling on the MBN pulse height distribution of relatively low carbon steel was investigated, and it was shown that randomly oriented undeformed grains result in a narrow symmetrical pulse-height distribution which shifts to lower values as grain size is reduced.

Physics of magnetism
TL;DR: Paleomagnetism is the study of the magnetic properties of rocks as discussed by the authors, and it is one of the most broadly applicable disciplines in geophysics, having uses in diverse fields such as geomagnetic, tectonics, paleoceanography, volcanology, paleontology, and sedimentology.

A Theory of Domain Creation and Coercive Force in Polycrystalline Ferromagnetics
TL;DR: Granular inclusions, grain boundaries, lamellar precipitates, and the crystalline surface have been examined as possible nucleation centers for domains of reverse magnetization in ferromagnetic materials as discussed by the authors.

Stress effect on the magnitude of acoustic emission during magnetization of ferromagnetic materials
H. Kusanagi,H. Kimura,S. Sasaki +2 more
TL;DR: In this paper, the effect of stress on the magnitude of acoustic emission during magnetization of mild steel and nickel has been investigated, and it has been shown that the acoustic emission shows a strong dependence on stress.
