| 摘 要： | 采用自蔓延高温合成结合准热等静压（ＳＨＳ／ＰＨＩＰ）制备出了具有对称结构的 ＴｉＣ－Ａｌ２Ｏ３／Ｆｅ梯度材料，并对其抗热冲击及抗热疲劳行为进行了测试和分析·结果表明， ＳＨＳ／ＰＨＩＰ制备的 ＴｉＣ－Ａｌ２Ｏ３／Ｆｅ梯度材料具有预期的梯度式组成，在热冲击和热疲劳实验过程中均无梯度层间横向贯穿裂缝，克服了传统陶瓷／金属直接接合界面的热应力剥落．

| Abstract: | The microstructure and composition distribution of TiC-Al2O3/Fe functionally graded materials(FGM) prepared by SHS/PHIP were studied, and the resisting thermal shock behavior was analyzed. The results show that TiC-Al2O3/Fe FGM has the desired composition distribution. The thermal shock fracture of TiC-Al2O3/Fe FGM originated from the surface on the side of ceramic and propagated perpendicular to the graded layer. And the crack of thermal fatigue originated and propagated in graded layer. However, no cross-section crevice through the graded layer was found in the two conditions. |
