Abstract
The present study utilizes pulse height distribution analysis to investigate the relationship between magneto-acoustic emission (MAE) and pearlite (carbon) content in iron and plain carbon steel. All of the samples were found to display the same basic features in the pulse height distribution—(1) a primary peak, attributed to 90° domain wall motion, and (2) a secondary peak, which became more pronounced at higher fields and was believed to be associated with domain magnetization vector rotation. In iron, the rotation component of MAE was dominant even at low levels of magnetization. In contrast, a fully pearlitic sample exhibited MAE produced primarily by 90° domain wall motion. Distributions from samples having “intermediate” compositions (containing both ferrite and pearlite) resembled one another more than either of the two “pure” component samples, suggesting a strong interaction between 90° domain wall processes and the ferrite/pearlite boundary.
