Interfacial Stability of Eutectic Composites
SourceComposites formed by unidirectional solidification of eutectic alloys usually exhibit a preferred crystallography of both phases and low-energy interfaces. Because of this, eutectic composites have been found to exhibit excellent microstructural stability and property retention after elevated temperature exposure. Some coarsening occurs at very high temperature without changing the basic aligned composite microstructure. The rate of coarsening is greater in finer microstructures and is related to the amount of interfacial area and the specific interfacial energy between phases.
