随着裂纹扩展，抗断裂能力的提高（r曲线响应）可以提高陶瓷的机械可靠性。为了了解微观结构如何影响r曲线行为，对SiC晶须增强氧化铝的裂纹相互作用与微观结构特征进行了直接观察。通过实验和理论研究，讨论了主要增韧机制对复合材料r曲线行为的影响。
Rising fracture resistance with crack extension (R-curve response) can lead to improvements in the mechanical reliability of ceramics. To understand how microstructures influence the R-curve behavior, direct observations of crack interactions with microstructural features were conducted on SiC whisker-reinforced alumina. The contribution of the dominant toughening mechanisms to the R-curve behavior of these composites is discussed using experimental and theoretical studies.
