The stress corrosion cracking behavior of Ti-8Al-1Mo-1V has been studied in several environments. Of the environments employed, methanol with a small addition of hydrochloric acid was found to be the most aggressive. Altering the microstructure of the alloy produced a marked improvement in resistance to stress corrosion cracking in distilled water and salt water media. The SCC susceptibility was also significantly decreased by the addition of sodium nitrate to both salt water and methanol plus hydrochloric acid environments. Fractographic analyses have been carried out and related to SCC behavior.
