Abstract:
A process for the production of a metal matrix composite consisting of discontinuous reinforcing particles in a metal matrix consisting essentially of aluminum, titanium or an alloy of titanium and aluminum, which comprises the sequential steps of (a) coating said reinforcing particles with at least one metal selected from the group consisting of aluminum and titanium by chemical vapor deposition to a thickness sufficient to fill the void space between said particles; and (b) consolidating the metal-coated particles to provide a reinforced metal article, wherein said reinforcing particles are selected from the group consisting of particulates of carbon, graphite, silicon carbide, aluminum oxide, zirconia, garnet, aluminum silicates including silicates modified with fluoride and hydroxide ions, boron carbide, simple or mixed carbides, borides, carboborides and carbonitrides of tantalum, tungsten, zirconium, hafnium and titanium, and intermetallics.
