Abstract
A boron containing ceramic-aluminum metal composite is formed by mixing a boron containing ceramic with a metal powder comprised of aluminum or alloy thereof, shaping the mixture into a porous preform, contacting the preform with an infiltrating metal comprised of aluminum or alloy thereof 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, such that the infiltrating metal infiltrates the porous preform to form the composite. The composite that is formed may be used for vehicular parts.
