Abstract
High strength forged aluminum alloys and methods for producing the same are disclosed. The forged aluminum alloy products may have grains having a high aspect ratio in at least two planes, generally the L-ST and the LT-ST planes. The forged aluminum alloy products may also have a high amount of texture. The forged products may realize increased strength relative to conventionally prepared forged products of comparable product form, composition and temper.

A forged aluminum alloy product comprising:
- a crystalline microstructure having grains;
- wherein the grains include first type grains and second type grains;
- wherein the crystalline microstructure comprises from 5 vol. % to 50 vol. % of the first type grains;
- wherein the first type grains at least include representative first grains;
- wherein the representative first grains make up 60-90 vol. % of the first type grains;
- wherein the representative first grains have an average aspect ratio of from 3.5:1 to 20:1 in the LT-ST plane;
- wherein the representative first grains have an average aspect ratio of from 6:1 to 30:1 in the L-ST plane;
- and
- wherein at least portions of the forged aluminum alloy product have a sectional thickness of at least 1 inch;
- and
- wherein the aluminum alloy of the forged aluminum alloy product is a 2xxx aluminum alloy.
