The results showed that for 2Y-TZP materials, because of low stabilizer content and small critical transformation size, more tetragonal zirconia could change into monoclinal, better effect of transformation toughening operated, hence higher fracture toughness was obtained.

晶粒尺寸、稳定剂含量对氧化锆陶瓷相变增韧效果具有重要的影响。2Y-TZP材料由于稳定剂含量低，临界相变尺寸也小，在低温烧结条件得到细晶粒情况下，断裂过程中有更多的晶粒达到或超过临界相变尺寸，因而具有更高的断裂韧性。

The microcrystalline strengthening effect is obvious, due to the sample with fine grain size that was wintered at low temperature and owned good bending strength. At the same time, also due to fine grain sizes, only less tetragonal zirconia grain that their sizes exceeded critical phase transformation size and could change into monoclinal phase when suffering stress, indistinct effect of transformation toughening operated, hence lower fracture toughness was obtained.

由于其晶粒尺寸较小，细晶强化的效果非常明显，因此，材料具有较高的抗弯强度；同时，由于晶粒小，只有一部分晶粒可以达到临界相变尺寸，相变增韧的效果不明显，因此试样的断裂韧性较低。

The results show that constitutional phases in the 〓 alloy is the same as that in the 〓 alloy, but phase composition and transformation temperatures of two alloys are quite different. The Ms temperature of the 〓 alloy is lower than-180℃. In order to enable the alloy to be used for making pipe couplings, it is necessary to control Al addition and to increase Ti addition in the alloy. In the 〓 alloy, there exist three constitutional phases: TiNi matrix phase with B19′structure,β-Ta phase and NiTa〓 phase. Transformation temperatures, M〓, Ms, As and A〓, of the alloy are 55℃, 66℃, 94℃ and 109℃, respectively.

结果表明，〓合金显微组织的相组成物与〓合金一样，但相成分明显不同，相变温度相差较大，其Ms温度低于-180℃，要想使该系合金用于制作记忆合金管接头，必须控制铝的添加量并提高合金中的钛含量使合金的Ms温度控制在-80℃～-100℃之间；〓合金是由具有B19'结构的TiNi基体相、β—Ta固溶体和NiTa〓化合物三相组成的，其相变温度M〓、Ms、As和A〓分别为：55℃、66℃、94℃和109℃。

The results indicate that the improved grey target could meet the invariance of effect samples after nonsingular linear transformation caused by clout distance; the weighted Mahalanobis distance is just the weighted Euclidean distance when there is no correlation among observed indexes, which avoids correlation of decision indexes, influences of different dimension and differences of importance on effect of decisions, and the incompatibility of grey target transformation.

结果表明，改进后的灰靶满足：靶心距对效果样本作非奇异线性变换的不变性；当观测指标间不存在相关性时，加权马氏距离就是加权欧氏距离。避免了决策指标间的相关性、不同量纲和重要性差异对决策效果的影响以及灰靶变换的不相容问题。
