Engine Titanium Consortium - Center for Nondestructive Evaluation ...

Improvements in detectability attainable through use of zoned ultrasonic inspection will be
quantified and documented, permitting subsequent assessments by the OEMs of the effectiveness
of such systems in improving the quality of titanium billet used for aircraft engine applications.
