Geometrical and Ultrasonic Modeling of Hard-Alpha Defect Components in Titanium Alloys

Overview of the ETC POD Methodology

“…As noted above, the methodology incorporates physical models of the inspection process, and an important step is the validation of these model predictions. Detailed validations have been conducted for flat-bottom holes (FBH) and synthetic hard alpha inclusions (SHA) [5][6][7] and similar effects are in progress for naturally occurring defects [8,9].…”
