| 摘 要： | 在Ｃｅ－ＴＺＰ中掺入０ｍｏｌ％～３ｍｏｌ％的Ｙｂ２Ｏ３，用ＸＲＤ、ＳＥＭ研究了Ｙｂ２Ｏ３掺入量对Ｙｂ－Ｃｅ－ＴＺＰ断裂相变量和显微结构的影响，讨论了Ｙｂ２Ｏ３的掺杂对Ｃｅ－ＴＺＰ材料力学性能的显著影响。实验表明，适量Ｙｂ２Ｏ３的掺入降低了Ｙｂ－Ｃｅ－ＴＺＰ的晶粒尺寸，提高了材料的断裂相变量，显著改善了材料的力学性能。在实验范围内，０．７５Ｙｂ－９Ｃｅ－ＴＺＰ表现出较优的力学性能。

| Abstract: | The 0mol%～3mol% Yb 2O 3 was added in Ce-TZP, XRD and SEM were used to investigate the increment of monoclinic phase content and microstructure before and after fracturing.The important influence of Yb 2O 3 additive on the mechanical properties of Ce-TZP was studied. It was found that proper amount of Yb 2O 3 additive can decrease the grain size, increase the fracturing increment of monoclinic phase content, improve the mechanical properties effectively. Especially, the 0.75Yb-9Ce-TZP showed the best mechanical properties in our experiments. |
