Acoustic Emission Behaviour of a Low Alloy Steel.

Abstract

Acoustic emission has become an important nondestructive evaluation technique, especially for pressure vessels. In the fabrication of heavy section pressure vessels, the materials experience various heat treatments which result in heterogeneous microstructures. Therefore, a program was undertaken to characterize the acoustic emission response to these variations in the microstructure of pressure vessel steel, namely, ASTM A533B steel. This data is intended to provide a base for evaluating field testing results and simultaneously to enhance the understanding of acoustic emission sources in martensite and bainite during deformation and fracture.
