The program started in 2007 under the Metals Affordability Initiative. The goal of the program is to evaluate and demonstrate capability of titanium based thermal protection systems. In the program, more than a half dozen of titanium alloy sheets (0.040~0.060 inch gage) and thin foils (approx. 0.003~0.004 inch gage) are produced for various evaluations including elevated temperature mechanical properties and oxidation resistance. This presentation will update and discuss the recent progress of the program.
