Abstract: A new technology for metal matrix composites-infiltration-semi-solid densification under pressure based on the analyses of kinds of conventional metal matrix composites preparation methods was proposed. Al2O3sf·SiCp/Al was prepared successfully by this new technology. The results show that the interface bonding is very good, the structure is very dense and the performance is excellent. It establishes the study foundation for metal matrix composites prepared by infiltration-stamp forging in semi-solid state integral technology.

 

Key words: metal matrix composites; infiltration; semi-solid densification
