ABSTRACT:
A dispersion strengthened mechanically alloyed aluminum-base alloy system is provided by a process comprising solution treating an alloy consisting essentially of, by weight, about 0.5 up to about 4% lithium, above 1% up to about 5% magnesium, about 0.5% up to about 2% carbon, a small but effective amount of oxygen which does not exceed 1%, and the balance essentially aluminum, the dispersoid content of the alloy being up to about 8 volume %. Preferred embodiments of the alloy are in the solution treated or solution treated and underaged condition are characterized by an improved combination of strength, low density, ductility, and fracture toughness.
