Magnetomechanical Acoustic Emission - A Review

Abstract

This article reviews magnetomechanical acoustic emission (MAE) that can be used in developing nondestructive testing techniques for residual stress measurements and microstructural characterization. Effects of metallurgical and magnetic parameters on MAE are considered drawing from basic studies on nickel and iron as well as from applied research on rail and wheel steels. Some of the observed features of MAE can be explained in terms of the domain theory. Practical applications require additional developmental efforts, but potential for useful residual stress analysis is well demonstrated.
