摘要：
A new pressing method was proposed for hot-pressing process.Experimental results indicated that the porosity in Al;O;/TiC/Ni/Mo （hereafter called Al;O;/TiC composite）composite compacts decreases by 6% after adopting this new technique.compared to traditional hot-pressing technique under the same sintering temperature. The flexural strength and Vickerhardness increase from 883 MPa to 980 MPa and from 16 GPa to 21.1 GPa, respectively.A theoretical model was given toanalyze the densification mechanism of the composite in the process of repetitious-hot-pressing.
