| 摘 要： | 在Si3N4基体中添加第二相粒子Ti(C0.12N0.88），研究Ti(C0.12N0.88）添加量对Si3N4-Ti(C0.12N0.88）复合材料性能的影响。结果表明，在Si3N4-Ti(C0.12N0.88）复合材料中，Ti(C0.12N0.88）在Si3N4基体中能够稳定存在，并能起到增韧初强的作用，添加适量的Ti(C0.12N0.88），Si3N4-Ti(C0.12N0.88）复合材料的抗弯强度和断裂韧性都有不同程度的提高。

| Abstract: | The effect of addition of the second phase particles to the Si 3N 4 matrix material on the mechanical properties of Si 3N 4-Ti(C 0.12N 0.88) composites was investigated. The experimental results show that the addition of Ti(C 0.12N 0.88) particles can improve the flexural strength and the fracture toughness of Si 3N 4-Ti(C 0.12N 0.88) composites. The second phase particles Ti(C 0.12N 0.88) are found to be stable in the Si 3N 4 matrix material. |
