Abstract
A method is taught for the in-situ precipitation of ceramic materials in a metal matrix. By means of the solvent assisted reaction, metal-ceramic composites having highly superior properties may be obtained. The invention involves the reaction of the ceramic forming constituents in a metal solvent medium to provide very finely-dispersed ceramic particles in the metal matrix. Exemplary materials include titanium diboride in an aluminum matrix.
