This book was released on 1966 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stress-corrosion behavior of four alloys of aluminum was investigated. Using cantilever-loaded fatigue-cracked specimens, the crack propagation characteristics of 7178-T6, 2014-T6, 2024-T351, and 7075-T6 aluminum alloys were determined. The aqueous environments used were: immersion in distilled water, constant immersion in 3-1/2 percent sodium chloride, and alternate immersion in salt solution and air. The results are interpreted in terms of fracture mechanics parameters. Where susceptibility to stress-corrosion exists, the rate of crak propagation is dependent upon stress intensity and environment. A method is also presented to obtain threshold values of stress intensity for stress-corrosion attack with minimal experimental effort. Results are compared to those of other testing methods.
