Abstract
A method of treating a blank of an aluminium base alloy comprising a combination of heat treatments and cold forming operations to produce a highly recovered semi-fabricated wrought product that is not statically recrystallized and that is inherently non-superplastic and is capable of superplastic deformation only after an initial non-superplastic deformation to achieve dynamic recrystallization.
