Quick Reaction Evaluation of Materials and Processes (QRE). Task Order 0008: Titanium Billet Characterization and Materials Properties Development (Nonconforming Titanium) - Executive Summary
Abstract
A previous federal investigation identified a risk associated with improperly processed titanium (Ti) material being used in the fabrication of critical components in several USAF and DoD systems. To investigate the potential for major mishaps, a USAF Titanium Task Force was formed to further define risk to USAF systems and to assist with mitigation efforts. An R&D testing program was designed to develop reasonable lower bound property data on a heretofore not fully characterized form of Ti for two alloys: Ti-6Al-4V and Ti-6Al-6V-2Sn. Such data was developed on both properly processed plate materials along with billet material, representing the improperly processed material. Key results obtained in this investigation have shown that improperly processed materials can have properties that do not meet specifications and requirements. Engineers and designers must account for reduced properties when assessing the integrity and safety of components that are, or may have been, made with the improperly processed materials described herein. This report provides data that should be used in such assessments.
