ABSTRACT:
A composite aluminum-base alloy having a mechanically alloyed matrix alloy. The matrix alloy has about 4-40 percent by volume aluminum-containing intermetallic phase. The aluminum-containing intermetallic phase includes at least one element selected from the group consisting of niobium, titanium and zirconium. The intermetallic phase is essentially insoluble in the matrix alloy below one half of the solidus temperature of the matrix alloy. The balance of the matrix alloy is principally aluminum. A stiffener of 5 to 30 percent by volume of the composite aluminum-base alloy is dispersed within the metal matrix.
