Abstract

Aluminum alloys having improved strength characteristics at elevated temperatures (300°C) are manufactured by combining selected transition metals (Ni, Co, Ti, Fe, Y, Sc) and selected rare earth materials (Er, Tm, Yb, Lu) in amounts of about 2 to 12% and 2 to 15% atomic percent respectively in an amorphous, glassy state and subsequently devitrifying the amorphous material to form a crystalline mix of fcc and L12 phase material. Devitrification from the amorphous state may be effected by various means including thermal and thermo mechanical processes.
