Abstract:

This document presents data on the compatibility of titanium alloys Ti-8Al-1Mo-1V and Ti-6Al-4V with flyaway materials, materials which might contact titanium in the airplane during its operation, proposed for use on the U.S.A. supersonic transport. Testing procedures are described in detail and results are tabulated. Flyaway materials were applied to two types of test specimens Heimerl-Braski self-stressed specimens, which were subjected to a bend deflection test following exposure, and simple U-bend specimens. For the Heimerl-Braski specimen configuration, a comparative statistical analysis of bend deflection test results was conducted. For the U-bend specimen configuration, stress corrosion, surface etch, and embrittlement effects were compared qualitatively. A rating of compatible or incompatible was assigned for each material-specimen-test parameter combination.
