Net-shape forming and properties of high volume fraction SiCp/Al composites

High performance SiCp/Al composites have been realized their net-shape forming by use of a novel process—ceramic injection molding (CIM) for the preparation of SiC preform and pressureless infiltration of aluminum alloys. The dimension precision of prepared SiCp/Al parts could reach about ±0.3%, and...

Zusammenfassung:High performance SiCp/Al composites have been realized their net-shape forming by use of a novel process—ceramic injection molding (CIM) for the preparation of SiC preform and pressureless infiltration of aluminum alloys. The dimension precision of prepared SiCp/Al parts could reach about ±0.3%, and their properties could also better meet the requirement of electronic packaging on the materials. In this paper, the CIM process to fabricate SiC preform and the infiltration of SiC preform by Al alloys have been discussed in detail. Additionally, the properties of prepared SiCp/Al composites have also been given research and evaluation.
