Abstract
An improved L1aluminum alloy having magnesium or nickel; at least one of scandium, erbium, thulium, ytterbium, and lutetium; at least one of gadolinium, yttrium, zirconium, titanium, hafnium, and niobium; and at least one ceramic reinforcement. Aluminum oxide, silicon carbide, aluminum nitride, titanium boride, titanium diboride and titanium carbide are suitable ceramic reinforcement particles. These alloys derive strengthening from mechanisms based on dislocation-particle interaction and load transfer to stiffen reinforcements.
