| 摘 要： | 以β-SiC为原始粉体，利用放电等离子烧结（SPS）工艺1800℃和1900℃制备了BAS／SiC陶瓷基复合材料．采用阿基米德排水法、XRD、SEM及三点弯曲等分析测试手段研究了复合材料的致密度、物相组成、微观结构及室温力学性能．结果表明，随着烧结温度升高，复合材料的致密度和室温力学性能增加，而复合材料的物相中没有发现β—SiC向α-iC的转变，这可能是由于SPS烧结速度较快相对而言烧结时间较短造成的．

| Abstract: | BAS/SiC composites were synthesized by sparking plasma sintering （SPS） at 1800℃ and 1900℃, respectively with β-SiC starting powders. Densification, phase composition, microstructure and room-temperature mechanical properties of the composites were studied by means of Archimedes＇ principle, XRD, SEM and three-point bending methods. The results showed the relative densities and mechanical properties of the composites increased with the sintering temperature increasing. No phase transformation happened from β-SIC to α-SiC, this could be due to the rapid sintering and short sintering time. |
