Zusammenfassung: | Present study aims to fabricate selectively reinforced aluminum hybrid composites using varying combinations of porous ceramic preforms containing discontinuous dispersoids of silicon carbide, aluminosilicate fiber, and carbon followed by direct squeeze infiltration processing of molten aluminum into the preforms. Porous preforms are successfully fabricated by the burn out of polyethylene glycol, and aluminum is used as the binder for the sintered body. Selectively reinforced hybrid aluminum composite has been successfully processed using liquid metal squeeze infiltration of porous preforms by controlled process parameters like preform preheating temperature, liquid metal temperature, squeeze pressure, and die temperature. |
