ABSTRACT:
The present invention relates to the formation of whisker reinforced metal matrix composites in which complex boride or carbide whiskers having an aspect ratio of greater than 10:1 are distributed throughout a metal, metal alloy, or intermetallic matrix. Exemplary complex boride whiskers include TiNbB, TiTaB, TiVB, NbHfB, and TiNbMoB. Exemplary complex carbide whiskers include TiNbC, TiVC, TiZrC, TiHfC, and TiTaC. A method for the in-situ formation of complex boride and complex carbide whiskers within metallic matrices is disclosed which involves reacting a mixture of individual complex ceramic-forming constituents in the presence of a metal to precipitate the desired complex ceramic whiskers in a metal matrix.
