Ceramic Matrix Composites (CMC's)
Specimen Preparation (Class 10 Procedures)
Metallographic Class 10 sample preparation

Description:

Ceramic matrix composites are used for either their high temperature resistance or there low wear characteristics.

Preparation Challenge:

Specimen preparation of these materials requires that the brittle phases be maintained.

Examples:
CERAMIC MATRIX COMPOSITE PROCEDURES
SiC fiber - Silicon Nitride Matrix
SiC fibers in Si3N4 matrix

Hafnium Diboride in a Boron Nitride Matrix
HfB2 fibers in BN matrix

SiC particles - Silicon Nitride Matrix
SiC particles in Si3N4 matrix

SiC particles - Zirconium Diboride Matrix
