Abstract

Magnetoacoustic emission (MAE) and Barkhausen emission (BE) measurements have been carried out on steel specimens heat treated to produce various microstructures ranging from martensitic/bainitic to ferritic/pearlitic. The magnetic domain structure of the specimens has been studied using transmission electron microscopy, and micromagnetic processes have been observed using an in-situ magnetizing device. The results are used in the interpretation of the MAE and BE measurements.
