Abstract
Abstract Continuous total immersion testing of pickled beryllium sheet material in synthetic sea water revealed mat corrosion rate decreases asymptotically from about 21.5 to 2.0 mpy as exposure period increased from 5 to 150 days. Beryllium was observed to be susceptible to severe pitting attack. Testing established that beryllium is susceptible to stress-corrosion when exposed to synthetic sea water. Time-to-failure decreased from about 2340 to 40 hours as applied tensile stress was increased from 1220 to 40,000 psi. Electron fractography studies suggested that stress-corrosion failure occurred transgranularly.
