SCC Susceptibility of the Titanium Alloy TA7 in Alcohols Solution

    Graphical Abstract
    • Abstract
  • The stress corrosion susceptibility of the titanium alloy TA7 in various alcohol solutions and the Cl- ion effect were investigated by using the SSRT testing method, SEM analysis and metallographic examination. The results show that the titanium alloy exhibits obvious susceptibility to SCC in ethyl alcohol and methyl alcohol and but more striking susceptibility to SCC in 0.6% HCl-methyl alcohol. SCC cracks of the titanium alloy in these solutions initiated in general from the bottom of pits.
