CLASS 9 - Metal Matrix Composites (MMC'S)
Examples include ceramic fibers in a metal matrix and/or ceramic particles in a metal matrix.

Description: Metal matrix composite applications have been found in high performance sporting goods and high performance military applications. They are primarily used to combine the hardness and energy absorbing characteristics of the ceramic with the bonding and ductility characteristics of the metal.

Preparation Challenge: Hard particles in a metal matrix can be difficult to microstructurally prepare because of particle pull-out, as well as excessive polishing relief between the hard particles and the softer matrix.
