摘要： A boron containing ceramic-aluminum metal composite with a density of at least 95 percent of theoretical density and comprised of at least 30 percent by volume aluminum metal or alloy thereof. The boron containing ceramic and at least one reaction product of the boron containing ceramic and aluminum are dispersed within the aluminum metal or alloy. At most a trace of Al 4 C 3 is present in the composite. The composite can be formed by mixing a boron containing ceramic with a metal powder comprised of aluminum or aluminum alloy, shaping the mixture into a porous preform, contacting the preform with an infiltrating metal comprised of aluminum or aluminum alloy that melts at a lower temperature than the metal powder and heating to a temperature sufficient to melt the infiltrating metal, but insufficient to melt the metal powder. The infiltrating metal infiltrates the porous preform to form the composite. The composite may be used for vehicle parts.
