Title:
【発明の名称】金属‐セラミック複合物内における複合セラミックホイスカーの形成
Document Type and Number:
Japanese Patent JPH03502821
Kind Code:
A
Abstract:
The present invention relates to the formation of whisker reinforced metal matrix composites in which complex boride or carbide whiskers 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.
