Abstract

Changes in the ultrasonic nonlinearity parameter, β, have been attributed to changes in dislocation density. This sensitivity suggests future applications in nondestructive testing. In this work, the change in β in rolled polycrystalline copper is examined. Methods for obtaining β are presented, with specific attention to sources of variations in measurements, thus ensuring repeatability. Finally, the changes in β are compared to changes in dislocation structure by hardness measurements and transmission electron microscopy.
