当Zr/B/C = 2：2：1的混合粉末经球磨机械活化（MA）后暴露于空气中时，其发生自发自点火和自蔓延高温合成（SHS），生成ZrB 2和ZrC。该粉末经放电等离子烧结（SPS）在1800 ℃下得到ZrB 2-ZrC复合材料，其显微组织细小均匀，力学性能为维氏硬度17.8GPa，断裂韧性3.8MPa m（1/2）。(C)2004 Elsevier B. V.保留所有权利。
When the powder mixture of Zr/B/C = 2:2:1 was mechanically activated (MA) by ball milling and then exposed to air, it spontaneously self-ignited and the self-propagating high-temperature synthesis (SHS) occurred to form ZrB2 and ZrC. The ZrB2-ZrC composite was obtained from this powder by spark plasma sintering (SPS) at 1800 degreesC and exhibited fine, homogeneous microstructure and the mechanical properties of Vickers hardness of 17.8 GPa and fracture toughness of 3.8 MPa m(1/2).
