Stress Corrosion Cracking of Titanium and Titanium Base Alloys in Aqueous and Gaseous Media.
Abstract
Bromine, Crack propagation, Moisture, Hydrogen embrittlement, Fracture(Mechanics), High strength alloys, X ray microscopy, Gas chromatographyOxygen was found to increase significantly the stress corrosion cracking susceptibility of titanium alloys to methanol and bromine environments and the initial exposure stage is highly sensitive to the presence of moisture which can absorb on the surface and provide a protective film of water. Cracking planes in single crystal specimens were affected by stress level, chemical factors, and specimen orientation. Depth profiles of hydrogen concentration by ion microanalyses were made of cathodically charged commercially pure titanium and titanium alloys and stress was found to be a factor in determining the tendency for absorption of hydrogen. The importance of anodic dissolution in the stress corrosion cracking process is considered and discussed in depth. (Modified author Abstract)
