Title:
HOMONIZATION OF ALUMINUM ALLOY BY HEAT TREATMENT
Document Type and Number:
Japanese Patent JPS58181852
Kind Code:
A
Abstract:
Aluminium alloys containing lithium and copper and/or magnesium as principal alloying constituents are homogenized at 530 DEG 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 DEG C/hour up to a final homogenization temperature in the region of 550 DEG -560 DEG C and are then allowed to cool without prolonged holding at temperature.
