Claims14
Aluminum base alloy comprising:
- from 3.0 to 18.5 weight percent nickel, from 3.0 to 14.0 weight percent yttrium, balance aluminum, said alloy being in the devitrified state and containing less than 40 percent intermetallic phases, said alloy being characterized by high strength and high ductility.
A process for making an aluminum alloy forming a billet of an aluminum alloy containing from 3.0 to 18.5 weight percent nickel, from 3.0 to 14.0 wt % yttrium, and balance aluminum;
- and
- extruding said billet at a temperature in the range of 700-900° F. and at an extrusion ratio greater than 10:1.
