| 摘 要： | 采用SPS烧结方法，通过测定密度、气孔率、硬度、抗弯强度以及组织观察，系统地研究了Al2O3对Ti3SiC2／Al2O3复合材料性能的影响。结果表明，在Ti3SiC2中添加适量Al2O3可以在强度及断裂韧性略有增加的前提下，大幅度提高材料的硬度，维氏硬度最高可达10．28GPa。当Al2O3含量过高时，材料强度、断裂韧性的下降是由于Al2O3的团聚所致。

| Abstract: | The effect of Al2O3 on the mechanical properties and microstructure of a Ti3SiC2/ Al2O3 composite fabricated by SPS(Spark Plasma Sintering)was studied in detail. The results show that the presence of the Al2O3 improves the hardness of the Ti3SiC2 up to 10.28 GPa. While at the same time increasing the strength and fracture toughness. On the other hand, slight decreases in flexural strength and fracture toughness were observed with Al2O3 additions higher than 10vol%, as a result of agglomeration of Al2O3 particles in the composite. |
