Abstract

PRE-CRACKED specimens of an alloy of titanium, aluminium, molybdenum and vanadium (90: 8: 1: 1) with a yield strength of 107,000 lb./in.2 were stressed in saturated hydrocarbons using the cantilever beam test designed by Brown1. The hydrocarbons were n-propane, and n-heptane and n-hexane of commercial purity (99+ mole per cent). These were contained in ‘Tygon’ or polyethylene cemented to the specimens with silicone rubber cement. During a test, the surface of the specimen containing a small fatigue crack was stressed in tension while submerged in one of the hydrocarbons.
