ABSTRACT:
An aluminum or aluminum-alloy material sheet comprised of an aluminum material having an ultra-fine, submicron grain structure. The strength and physical properties of the aluminum or aluminum-alloy material sheet are improved over previous aluminum and aluminum-alloy material sheets because the aluminum is produced by cryomilling the aluminum or aluminum-alloy materials into a metal powder with ultra-fine, submicron grain structure. The powder is consolidated and rolled into the form of a sheet.
