ALUMINUM SHEET PRODUCTS HAVING IMPROVED FATIGUE CRACK GROWTH RESISTANCE AND METHODS OF MAKING SAME

摘要

Aluminum sheet products having highly anisotropic grain microstructures and highly textured crystallographic microstructures are disclosed. The products exhibit improved strength and improved resistance to fatigue crack growth, as well as other advantageous properties such as improved combinations of strength and fracture toughness. The sheet products are useful for aerospace and other applications, particularly aircraft fuselages.
