| 英文摘要 | SiC-30vol%VB2 ceramic composite was pressureless densified at 2150 degrees C with excess B4C and C as sintering aids after in-situ formation of VB2 in SiC matrix. The sintered bulk gained a considerably high fracture toughness of 7.0 +/- 0.4 MPa m(1/2), which was similar to 2.4 times as high as that of the monolithic SiC ceramic, owing to the existences of weak heterophase boundaries, thermal residual stresses and microcracks. Meanwhile, since the VB2 particle has a lower elastic modulus than SiC and significantly suppressed the grain growth of SiC, the composite exhibited a high flexural strength of 458 +/- 36 MPa and a relatively low Young's modulus of 356 +/- 6 GPa, resulting in an increase of similar to 59.3% in mechanical strain tolerance (1.29 x 10(-3)) compared with that of single-phase SiC ceramic. Besides, the residual stresses and microcracks also induced a lower-than-expected Vickers hardness of 20.8 +/- 0.5 GPa in the composite. (C) 2016 Elsevier Ltd. All rights reserved. |
