Engineering Design Data for Aluminum Alloy 7050-T73651 Plate

Abstract

Mechanical properties of aluminum alloy 7050-T73651 one-inch thick plate were determined and then compared to other high strength aluminum alloys. The fracture, fatigue crack growth, and stress corrosion properties and the flaw sensitivity index for the 7050-T73651 alloy were equal to or better than similar properties for other 7000 series aluminum alloys at similar strength levels. Conventional notched and smooth fatigue data indicated that the 7050- T73651 alloy had fatigue properties somewhat below those of 7049-T73, but equal to most other aluminum alloys. Environmental fatigue crack growth tests indicated that the crack growth rate was significantly accelerated by the presence of a 3.5 per cent sodium chloride solution environment. Changes in the specimen width were found to have an effect on the conditional fracture toughness values. (Author)
