Abstract

Using the diffusion bonding process in a Ti-alloy, a variety of obstacles of carefully controlled size and shape has been imbedded into a nearly uniform solid medium. The obstacles considered are cavities in the shape of disks, cylinders and spheres. Experimental data are compared with the results of computer calculations for the back scattering of ultrasonic waves in the technologically important regime lambda equals obstacle dimensions. The usual simplifying approximations such as those made for Rayleigh scattering from an object in a liquid or gas were found to be not always applicable. The results show dramatic differences in the intensity of the scattered wave and its frequency dependence and should be significant for nondestructive testing applications.
