Experimental results indicated that the porosity in Al2O3/TiC/Ni/Mo (hereafter called Al2O3/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. 关键词：复合陶瓷热压烧结重复热压烧结制备工艺实验研究
