ABSTRACT:
A process for improving the properties of low density aluminum alloys comprises a controlled heat and cooling treatment of a shaped alloy to obtain a product which in the non-aged condition has improved fracture toughness without sacrificing tensile properties. The product is particularly useful for treating forged Al-Li-Mg alloys.
