STRESS-CORROSION TESTS ON COMMERCIAL AND HIGH PURITY GRADE 7075-T6 ALUMINUM ALLOY.
Abstract
Alternate immersion stress-corrosion tests were conducted on commercial and high purity 7075-T6 aluminum alloy stressed in the short transverse direction at levels of 8000 psi to yield strength. No failures occurred in the commercial grade at stress levels of 20,000 psi or less. In the high purity grade, the highest stress which did not produce failures was 10,000 psi. At levels of 30,000 psi or less, the commercial grade specimens had a life of three or more times that of the high purity specimens. (Author)
