Bent-beam specimens selected from the high strength groups of each of the alloys have accumulated over 21 weeks of exposure time in the environments of distilled and tap water. Some failures were observed with alloy specimens that were exposed to distilled water. U-bend specimens have undergone over 28 weeks of testing, and significant failures were noted in several of the environments. Selected bent-beam specimens, coated with solid propellant, have undergone 3 weeks of exposure without failure. A high-temperature high-humidity environment produced the most rapid stress-corrosion failures. Of the room- temperature environments, distilled water was found to produce the most rapid failures.
