Fabricating a 15 vol%-3.5 μm-SiCp/Al composite by a squeeze casting technique

The fabrication of a 15 vol%-3.5 μm-SiCp/Al composite by a squeeze casting technique is discussed. Squeeze casting process is an economic route for fabricating particle reinforced aluminum composites. In the squeeze casting process, aluminum melt infiltrates into the particle preform and then solidifies under a high pressure. It is found that the fabrication process is an effective process to lower the volume fraction and improve the distribution of the particle in the SiCp/Al composite.
