    A microstructural approach has been used to explain the deformation characteristics which influence the formability of aluminum alloy sheet materials. Optical metallography and transmission electron microscopy were used to study the response of various aluminum alloys to uniaxial and biaxial deformation. The predominant strengthening mechanisms for a given alloy had the strongest effect on strain localization and biaxial strain hardening behavior. Dispersion-strengthened alloys displayed a wavy slip mode, and high levels of strain hardening and resistance to strain localization. Precipitation or solid-solution-strengthened alloys exhibited more localized deformation and lower capacities for biaxial strain hardening.
