Abstract
A method is provided for producing dispersion-strengthened mechanically alloyed Al-Li alloys with improved mechanical properties. The method comprises subjecting mechanically alloyed, degassed, consolidated Al-Li powders consisting essentially of from above 1.5% up to about 3.5% lithium from about 0.4% up to about 1.5% oxygen, from about 0.2% up to about 1.2% carbon and the balance essentially aluminum, to a heat treatment which will produce an aging response in the alloy.
