| 摘 要： | 分析研究了挤压复合温度对Ｋ２Ｏ·６ＴｉＯ２Ｗ／ＺＡ２７合金复合材料的拉伸断口分形维数的影响规律及与拉伸断裂功之间的关系。研究发现该复合材料的拉伸断口具有统计自相似性，可以用分形维数来描述，自相似性的测量步长范围在０．１８５～３．７５０μｍ之间为最佳。复合材料拉伸断口分形维数同拉伸断裂功之间有较好的对应关系，分形维数随拉伸断裂功的增加呈线性增大。

| Abstract: | The tensileproperties were measured by using Instron tensile machine. The fracture surface of K2O*6TiO2W/ZA-27composites was studied by using fractal geometry. The results on fractal dimension oftensile surface showed that the fracture surface of K2O*6TiO2W/ZA-27composites has statistics self-similar property and can be investigated and described byfractal dimension. There exist good corresponding relations between tensile fracture workof composites and fractal dimension of fracture surface. The micro-mechanism of tensilefracture of composites was also discussed. |
