Abstract:

Tensile, fracture, fatigue, fatigue crack growth, and stress corrosion properties for aluminum alloy 2124-T851 thick plate were determined. Material property comparisons were then drawn between the 2124-T851 alloy and its parent alloy, 2024, in the T851 condition. A comparison of the mechanical properties of aluminum alloy 2124-T851 and 2024-T851 revealed that the 2124-T851 alloy exhibited similar tensile properties with possibly less short transverse ductility, superior fracture toughness, comparable fatigue properties with slightly lower smooth fatigue resistance, and identical fatigue crack growth rates. The 2124-T851 alloy also demonstrated good stress corrosion resistance.
