摘要：
The stress corrosion cracking (SCC) behavior of Ti-8Al-1Mo-1V has been studied in several molten salt environments. Extensive data are reported for the alloy in highly pure LiCl-KCl. The influence of the metallurgical heat treatment and texture, and the mechanical microstructure show similarities with aqueous solutions at lower temperature. The fracture path and cracking modes are also similar to that found in other environments. Finally, the influence of H//2O and H** minus in molten LiCl-KCl lead to the conclusion that hydrogen does not play a major role in crack extension in this environment.
