Abstract

Experimental data are compared with theoretical calculations for the scattering of ultrasonic pulses from a single spherical cavity embedded in a metallic solid. Except at high frequencies, the data are in reasonable agreement with theory, bearing out the notable features predicted for the angular dependence and the mode conversion between longitudinal and transverse waves. At high frequencies the disagreement can be accounted for by the lack of monochromicity in the ultrasonic pulse, and the technique for analyzing the data taking into account the broadband spectrum must be applied. The experimental parameters were chosen to span the regime where the wavelength is of the order of the size of the spherical cavity (0.8mm) on samples of diffusion bounded Ti-6% Al-4% V.
