Description

The ultrasonic detection of altered microstructures in metals is a difficult, but necessary task. The detection of hard alpha inclusions in titanium jet engine disks is an important, safety related, example of the need. One proposed tool for detecting such altered microstructures involves analyzing changes in the ultrasonic grain noise; i.e., in the incoherent part of the scattered signal.
