ANALYSIS OF STRESS-CORROSION CRACKING OF TI-6AL-4V FUEL TANK MATERIAL IN METHYL ALCOHOL.

Abstract

Material from a high yield strength 6Al-4V titanium alloy space vehicle fuel tank was found to be susceptible to stress-corrosion cracking in methyl alcohol by an unidentified cleavage mechanism. Cracks propagated in contact with methanol at plane strain stress intensities as low as 15 ksi in. The same material was found to be somewhat susceptible to cracking in distilled water, by the same mechanism, with a crack propagating at a plane strain stress intensity of about 30 ksi in. (Author)
