| 英文摘要 | B4C-ZrB2 ceramics were reactively hot pressed by three-step process using B and C with Zr (C-B-Zr mixtures) or ZrO2 (C-B-ZrO2 mixtures) as raw materials. Based on thermodynamic analysis and experimental results, the C-B-Zr or C-B-ZrO2 mixtures were firstly held at 1000 degrees C, then held at 1650 degrees C, and finally held at 2000 degrees C under 30 MPa. B4C-ZrB2 ceramics were obtained by using the three-step process and controlling the reaction sequence. The ZrB2 grains in B4C-ZrB2 ceramics from C-B-Zr mixtures had a bimodal grain size distribution including fine grains with size of 1-2 mu m and large agglomeration-like grains with size of 10-30 mu m, while that in the ceramics from C-B-ZrO2 mixtures showed homogeneous distribution with small grain size of 1-2 mu m. The B4C-ZrB2 ceramics from C-B-ZrO2 mixtures showed higher relative density, more homogeneous and fine-grained microstructure, higher hardness (33.0 +/- 1.3 GPa), and comparable toughness (4.1 +/- 0.2 MPam(1/2)), compared with the ceramics from C-B-Zr mixtures.
