| Abstract | 在室温下，利用WDW—E100D万能试验机和SEM研究了三维连通网状结构SiC陶瓷／Zr基非晶复合材料的准静态单轴压缩变形和断裂行为．结果表明，复合材料的轴向压缩断裂强度达到了1270MPa，在压缩条件下复合材料的断裂发生在弹性变形阶段，断裂前观察不到塑性变形；试样发生纵向劈裂和剪切断裂；三维连通网状结构SiC陶瓷是主要的承载单元，断口形貌为层片状、台阶式的解理断裂；非晶合金发生粘性流动，在变形过程中形成纹脉状断口形貌．出现典型的热软化效应． |
| Other Abstract | The deformation and fracture behaviors of 3D-net SiC/Zr-based amorphous composites have been investigated with the WDW-E100D testing machine and scanning microscopy （SEM） under monaxial compression at room temperature. It is found th compressive strength of the composites reaches 1 270 MPa. Under compressive loading, the matrix electron at, the samples exhibit elastic deformation followed by catastrophic failure without obvious yielding. The mode of failure of the composites is a mixture combining splitting and shear fracture. The 3D-net ceramic is the dominating cell bearing the weight; the microcosmic failure mechanical are typical cleavage fracture of 3D-net SiC, and inhomogenous flow deformation of amorphous alloys viscous flow traces, vein patterns and localized melting can be seen on the fracture surface of the amorphous alloys matrix. |
