Metal-matrix interpenetrating phase composites produced by squeeze casting

摘要

On the basis of the proposition and manufacture of a new type of metal matrix interpenetrating phase composites (MMIPCs) by vacuum high pressure infiltration, squeeze casting method was chosen for further study on this new type of MMIPCs. By employing the highly porous ceramic perform made from SHS reaction of Al TiO 2 C system, squeeze casting process was studied in detail. By means of OM, SEM and TEM, the obtained highly porous SHS reaction products and the resulting MMIPCs for further understanding were closely examined and analyzed.
