Abstract

Results are presented on the scattering of ultrasonic waves from defects embedded in metals and on the influence of these defects on the mechanical properties. A simple correlation has been discovered between an empirical expression for the ductility of a sample containing a single void and the back-scattered ultrasonic power derived from scattering theory. An expression is derived which relates the ductility (reduction in cross-sectional area at tensile fracture) with the high-frequency (15 MHz) back-scattered ultrasonic signal in an approximately linear fashion. The data obtained on diffusion bonded Ti-alloy samples are in good agreement with the predictions. These results open the door to the prediction of ductility from ultrasonic measurements.
