Abstract
The invention comprises an alloy having improved intermediate temperature properties at temperatures up to about 316.degree. C. The alloy contains (by weight percent) about 1-6% X contained as an intermetallic phase in the form of Al.sub.3 X. X is at least one selected from the group consisting of Nb, Ti and Zr. The alloy also contains 0.1-4% strengthener selected from the group consisting of Si and Mg. In addition, the alloy contains about 1-4% C and 0.1-2% O present as aluminum carbides and oxides for grain stabilization.
