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
Grain size measurement using magnetic and acoustic Barkhausen noise
TL;DR: In this article, it was shown that the number of counts of both magnetic and acoustic Barkhausen signals vary inversely with grain size, and the amplitude of both signals increased in proportion to grain size.

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.

Improvement of the Barkhausen noise method for stress evaluation
TL;DR: In this paper, the authors measured the Barkhausen noise bursts for ferritic-pearlitic, tempered microalloyed, 3.5Ni and 9Ni steels in an unloaded state and under tensile stresses, and the area Ar, peak amplitude Vm and restricted area RAr was determined.
