Abstract
Abstract Alloy specimens of Ti-8Al-1Mo-1V were salt-coated and exposed to conditions conducive to hot salt stress corrosion. Subsequent tensile tests revealed that ductility was strain rate and temperature sensitive. Embrittlement was more pronounced at slow crosshead speeds in the vicinity of ambient temperature. After salt exposure, ductility was restored by vacuum annealing. Substantial increases in hydrogen content were measured in embrittled specimens. These results demonstrate that hydrogen can be generated during elevated temperature exposure to salt and that the subsequent embrittlement is a manifestation of “slow strain rate” hydrogen embrittlement.
