Abstract : This investigation of the fracture behavior of titanium in the marine environment evaluated a spectrum of titanium alloys for loss of fracture resistance in seawater. A comparison of the wet-stress-cracking behavior was made with metallurgical variables. Sensitivity was found to be related to the titanium-aluminum embrittling reaction and was dependent on aluminum content, isomorphous beta stabilizer content, and heat treatment. Control of the factors leading to the titanium-aluminum reaction appears to provide a means of eliminating the problem or reducing it to the extent that alloys will be safe to use. A program to accomplish such control is outlined. (Author)
