Abstract: The present invention provides an aluminum hybrid metal matrix composite including cerium and graphite. The aluminum-cerium intermetallic is stable at temperatures up to a melting point of aluminum and graphite provides in situ lubrication. This stability is advantageous in applications such as cylinder liners and other applications where strength and stiffness at elevated temperatures are required.
