Mechanical Property Data on Aluminum Alloy 7150-T7751 Plate

Abstract

A mechanical properties investigation was performed on aluminum 7150- T7751, a product using a recently developed thermal processing technique. Properties examined were tensile, fracture toughness, fatigue crack growth, spectrum fatigue crack growth, constant amplitude fatigue, stress corrosion cracking, and stress corrosion cracking threshold. Test results indicate this material possesses high strength with somewhat greater resistance to corrosion and decreased fracture toughness over conventional 7000 series aluminums of similar strength. Fatigue properties were found to be similar to those of other 7000 series aluminums, while fatigue crack growth rates were greater in the lower stress intensity ranges and similar in the higher ranges. Keywords: Stress corrosion cracking, Stress corrosion threshold, Spectrum fatigue, Constant amplitude fatigue crack growth, Tensile, Fracture toughness.
