Abstract

A recrystallized aluminum alloy having brass texture and Goss texture, wherein the amount of brass texture exceeds the amount of Goss texture, and wherein the recrystallized aluminum alloy exhibits at least about the same tensile yield strength and fracture toughness as a compositionally equivalent unrecrystallized alloy of the same product form and of similar thickness and temper.
