| 英文摘要 | Ta0.8Hf0.2C-27 vol%SiC (99.0% in relative density) composite was toughened and strengthened via pressurelessly in-situ reactive sintering process. HfC and beta-SiC particles were formed after reaction of HfSi2 and carbon black at 1650 degrees C. Ta0.8Hf0.2C was obtained from solid solutioning of HfC and commercial TaC. The beta-alpha phase transformation of SiC proceeded below 2200 degrees C. High aspect ratio, platelet-like alpha-SiC grains formed and interconnected as interlocking structures. Toughness and flexural strength values of 5.4 +/- 1.2 MPa m(1/2) and 443 +/- 22 MPa were measured respectively. The toughening mechanisms by highly directional growth of discontinuous alpha-SiC grains were crack branching, bridging and deflection behaviors. |
