Relationship Between the Two-Point Correlation of Elastic Constants and Backscattered Ultrasonic Noise in Two-Phase Titanium Alloys
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.
