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
Effect of antiphase boundaries on the magnetic properties of Cu-Mn-Al Heusler alloys
A. J. Lapworth,J.P. Jakubovics +1 more
TL;DR: The magnetic properties of Heusler alloys of approximate composition Cu2MnAl have been studied by Lorentz microscopy as discussed by the authors, showing that magnetic domain walls have been observed to be pinned at antiphase boundaries.
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.
