| Abstract: | On the basis of the proposition and manufacture of a new type of metal matrix interpenetrating phase composites (IPCs) by vacuum high pressure infiltration, a squeeze casting method was chosen for further study on this new type of metal matrix IPCs. By employing the highly porous ceramic preforms made of self propagating high temperature synthesis(SHS) reaction of Al TiO 2 C system, squeeze casting process was studied. By means of OM, SEM and TEM we have closely examined and analyzed the obtained highly porous SHS reaction products and the resulting metal matrix IPCs for further understanding. |
