查询词典 titanium dioxide

First of all, titanium has excellent biocompatibility, high mechanical strength and low proportion; the second, the potential biological toxicity of non-noble alloys (such as alloys of Co-Cr and Ni-Cr)was avoided; the third, the disadvantage of over-abrasion of antagonization teeth resulted from high rigidity of porcelain was also avoided; the last, metal-resin bonding prostheses was easy to be repaired in mouth.

The results indicate that the effect of alloying elements V and Cr on mechanical properties at room-temperature, creep behavior and microstructures are similar. With increasing contents of V and Cr, their mechanical properties produce little change, the creep resistant property decreases and microstructure grows, which is mainly due to their characteristics of β-stability element and smaller atomic radius compared with Ti. On the contrary, the effects of V and Cr on the thermal stability are quite different. With increasing V content or decreasing Cr content the thermal stability for the alloy becomes better, which may be due to the different solution characteristics of V and Cr element in titanium alloy that V belongs to isomorphous β-stability element and Cr belongs to eutectoid β-stability element.

结果表明：合金元素V和Cr对Ti40合金室温力学性能、蠕变行为和组织的影响具有相似性，即随V和Cr含量的降低，合金室温综合力学性能变化不明显、抗蠕变能力减弱、组织粗化：这与V和Cr同属于β稳定元素、且原子半径都小于Ti原子有关；而V和Cr对于热稳定性能的影响则完全相反，V含量的增加或Cr含量的降低含金热稳定性能优化，其主要原因可能与V属于同品型β稳定元素而Cr属于共析型β稳定元素有关。
