| Abstract: | TiC Ni composites have been prepared by combining forced compaction with self propagating high temperature synthesis (SHS).The experimental results show that process parameters significantly influence the quality of TiC Ni products by combustion synthesis. Optimal process parameters have been obtained for preparing TiC Ni FGM and composites, including 56% of preform density ,10 MPa of pre pressure P 1, pressing time t 1, 160 MPa of high pressure P 2 and 20 s of dwell time t 2 at high pressure period. |
