Journal ArticleDOI
Magneto-acoustic and Barkhausen emission: Their dependence on dislocations in iron
TL;DR: Magneto-acoustic emission (MAE) and Barkhausen emission (BE) have been measured from polycrystals of pure iron which were then heat-treated at successively higher temperatures as mentioned in this paper.
Journal ArticleDOI
The measurement of stress in steels of varying microstructure by magnetoacoustic and Barkhausen emission
TL;DR: Magnetoacoustic emission (MAE) and Barkhausen emission (BE) have been measured as a function of applied magnetic field and tensile stress from mild-steel samples in a wide range of heat treatments, to develop a technique to measure stress without prior knowledge of the microstructure as mentioned in this paper.
Journal ArticleDOI
Magnetoacoustic and Barkhausen Emission in Ferromagnetic Materials
TL;DR: Magnetoacoustic emission (MAE) and Barkhausen emission (BE) have been studied in ferromagnetic materials placed in a magnetic field, varying at a few millihertz as mentioned in this paper.
Journal ArticleDOI
Magneto-acoustic and Barkhausen emission from domain-wall interactions with precipitates in Incoloy 904
TL;DR: Magneto-acoustic emission (MAE) and Barkhausen emission (BE) were measured from single crystals and polycrystals of Incoloy 904 alloy, in which a uniform, random distribution of coherent spherical precipitates (non-magnetic inclusions) forms on isothermal ageing.
