| 摘 要： | 用渗流理论讨论了Ti-Al2O3金属陶瓷的显微结构同宏观电导率的关系,发现渗流模型结果与实验结果是一致的。该Ti-Al2O3金属陶瓷的渗流阈值为(Ti的临界百分含量)ω*=0.16,其临界指数即为三维连续渗流的临界指数值。

| Abstract: | The relation between the microstructure and the macroscopic conductivity of Ti-Al2O3 cermet is analysed by using percolation theory. It is found that the result of percolation model is consistent with experimental result. The percolation threshold ω* the critical percent content of Ti-Al2O3 cermet is 0.16, and critical exponents are the same as those of three-dimensional continuous percolation. |
