Fabrication of metal matrix composite by spontaneous infiltration and subsequent in situ reaction processes.

Fabrication process of aluminum matrix composite was developed by applying the in situ reaction followed by spontaneous infiltration of liquid aluminum into the ceramic powder mixed with metal powders. Further, the spontaneous infiltration of liquid magnesium into the SIC powder phase was also completed with help of the infiltration agent of SiO2 mixed in SiC powder phase.
