METHODS OF MAKING HIGHLY-FORMABLE ALUMINUM ALLOYS AND ALUMINUM ALLOY PRODUCTS THEREOF

Provided herein are highly-formable aluminum alloys and methods of making such alloys. The method of preparing aluminum alloys described herein can include a low final cold reduction step and/or an optional inter-annealing step to produce randomly distributed crystallographic texture components that produce an isotropic aluminum alloy product exhibiting improved formability and deep drawability. The methods described herein result in aluminum alloy microstructures having a balance of alpha fibers and beta fibers that promote improved formability of aluminum alloy sheets. The resulting improvements in quality allow for shaping processes with reduced rates of spoilage. 本文提供了高度可成形的铝合金以及制造此类合金的方法。本文所述的制备铝合金的方法可包括低最终冷减缩步骤和/或任选的中间退火步骤，以产生随机分布的晶体织构成分，从而产生表现出提高的可成形性和深拉性的各向同性铝合金产品。本文所述的方法产生了具有α纤维和β纤维平衡的铝合金微结构，所述铝合金微结构促进铝合金薄片的可成形性提高。所获得的质量提高使得成型过程的损耗率降低。
