The Effect of Thickness Upon Sustained Load Crack Propagation in Ti-6Al- 4V alloy Tested in 3-1/2% NaCl Solution

Abstract

The titanium alloy Ti-6Al-4V was found to be susceptible to sustained load cracking in 3-1/2% NaCl solution, and this susceptibility increased with specimen thickness. The sensitivity to thickness was found in the thickness range near that required for plane strain crack propagation. Cracking rates were also found to increase with increasing specimen thickness. The mechanism for the sustained load cracking may have been either a stress corrosion cracking mechanism arising from the presence of the salt water or a hydrogen-assisted cracking mechanism arising from the hydrogen content of the alloy.
