摘      要：Al/Al203 composites of different ratios were hot-press sintered at 575~640℃ under a pressure of 30 MPa for 2 h in a vacuum furnace. It was found that the relative density of the Al/Al203 composites could be increased evidently with the rise of sinter temperature. No reaction occurred between At and Al203 at the sinter temperatures. Under 640℃-30 MPa-2 h experimental condition, Al/Al203 system FGM was successfully fabricated, and its density range changed quasi-continuously from 2.887×103 kg/m3 to 3.1909×103 kg/m3 within the middle 1.0 mm thickness range.
