Evaluation of microstructures in 2.25Cr-1Mo and 9Cr-1Mo steel weldments using magnetic Barkhausen noise
TL;DR: In this paper, the magnetic Barkhausen Noise (MBN) measurements have been used to characterise different microstructural regions such as coarse grain region, fine grain regions, intercritical structure (composed of retained austenite and tempered ferrite) within the heat affected zone (HAZ) of 2.25Cr-1Mo steel and 9Cr 1Mo steel weldments using simulated HAZ microstructure samples.

On the shape of the magnetic Barkhausen noise profile for better revelation of the effect of microstructures on the magnetisation process in ferritic steels
TL;DR: The shape of the Magnetic Barkhausen Noise (MBN) profiles has been compared for two different methods of MBN measurements in order to reveal the true extent of the influence of different carbon-content related microstructures on the magnetisation process.

Dependence of the magnetic Barkhausen emission with carbon content in commercial steels
TL;DR: In this paper, the dependence of the magnetic Barkhausen Effect (MBE) with carbon content in commercial steels has been studied and the cause of this dependence was analyzed on the base of domain walls theory.

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.
