Abstract
An intermetallic composite and method of making an intermetallic composite is disclosed comprising a porous titanate preform of the formula .epsilon..sub.xTi.sub.yO.sub.z, where .epsilon. represents an element reduceable by molten aluminum to form an aluminate of the formula .epsilon..sub.iA.sub.jO.sub.k. Adding aluminum and heating the preform sufficient to melt the aluminum results in formation of a post-combustion intermetallic composite comprising both titanium aluminide and 68 -aluminate.
