Abstract

Demands for advanced materials which can endure hostile environments (high temperature, high stress) constantly increase. In such hostile environment, even small defects may result in component failure. For instance, a small, hard alpha defect in a titanium alloy rotating component of a jet engine could initiate a crack resulting in engine failure. Therefore, it is important to detect small defects in advanced materials such as titanium alloys. Ultrasound is often used for these purposes.
