Abstract
Aluminum alloys containing lithium and copper and/or magnesium as principal alloying constituents are homogenized at 530.degree. C. or above to take into solution as-cast intermetallic phases which do not fully go into solution at conventional homogenization temperatures for this class of alloy. Preferably the alloy ingots are slowly heated at rates not exceeding 50.degree. C./hour up to a final homogenization temperature in the region of 550.degree.-560.degree. C. and are then allowed to cool without prolonged holding at temperature.
