| 摘 要： | 本文观察分析了两种国产ＳｉＣ晶须的表面杂质元素和形貌，得知晶须Ａ表面光滑，其中有少量晶须是弯曲状，晶须Ｂ比较平直，表面粗糙．晶须Ａ中包含有许多堆垛层错（Ｓｔａｃｋｉｎｇｆａｕｌｔｓ），人字状花纹缺陷（Ｃｈｅｖｒｏｎｄｅｆｅｃｔｓ）和锯齿状缺陷，而晶须Ｂ中仅观察到有堆垛层错．测试了这两种晶须增韧的氧化铝陶瓷刀具材料的性能，并探讨了晶须增韧氧化铝陶瓷刀具材料的机理．

| Abstract: | Two kinds of home-made whiskers from different supplier were characterizedby X-ray diffraction, transmission electron microscopy and scanning electron rnicrocopy.Whisker A has a much smoother surface profile than whisker B. While whisker B seems morestraight than whisker A. Whisker A contained a high density of stacking faults, chevron defects and sawteeth faults along their entire length, while whisker B contains only stackingfaults. The mechanical properties of the two kinds of reinforced ceramics tool materials weredisscussed in order to investigate whisker toughening effeet. |
