ABSTRACT:
Aluminum alloy compositions and related fabrication techniques are described. Articles made of the composition by the process contain a novel dispersed strengthening phase based on iron and refractory metals. Rapid solidification techniques are used to assure a fine distribution of this phase. Articles made according to the invention have mechanical properties significantly in excess of those of conventional aluminum alloys.
