Description

The engine titanium consortium is currently conducting an extensive study of the ultrasonic response and detectability of a number of naturally occurring hard-alpha defects found in titanium billets. These naturally occurring defects appear to be highly irregular in shape and inhomogeneous in composition, and we would like to access the extent to which their responses can be predicted by available ultrasonic scattering models [1]. Three dimensional geometrical (surface and solid) models of the hard-alpha defects are needed in order to obtain the geometrical and material properties to drive the ultrasonic model calculations and the subsequent probability-of-detection evaluation [2].
