Metal Matrix Composites (MMC's)
Metal matrix composites have found applications in both the sports as well as military. They are primarily used to combine the hardness and energy absorbing characteristics of the ceramic with the bonding and ductility characteristics of metal.
As will other composites, specimen preparation must maintain flatness across the varying component hardness’. In addition, the correct preparation process should result in a microstructure which has avoided pulling out the brittle component.
