  zr
Lead zirconium titanate (PZT) films (Zr/Ti=45:55) with a high dielectric constant are prepared successfully on the low-resistance Si substrate in sol-gel dip-coating process with PT film used as the buffer layer.
      
The solid acids were prepared by mounting H2SO4 on TiO2 · nH2O and Zr(OH)4, respectively, followed by calcining at 823K.
      
To deal with this contradictory situation, insolvable zirconium tricarboxybutylphosphonate (Zr(PBTC)) powder was employed to make a composite with SPEEK polymer in an attempt to improve temperature tolerance of the membranes.
      
SPEEK/Zr(PBTC) composite membranes were obtained by casting a homogeneous mixture of Zr(PBTC) and SPEEK in N,N-dimethylacetamide on a glass plate and then evaporating the solvent at 60°C.
      
Results showed significant improvement not only in temperature tolerance, but also in methanol resistance of the SPEEK/Zr(PBTC) composite membranes.

The isothermal sections at 1200℃ of the systems Mo-Ti-Zr and Mo-Nb-Zr have been determined by metallographic and X-ray diffraction methods supplemented by hardness measurements. The constitutions of these two systems are strikingly similar; besides a b.c.c, ternary terminal solid solution and a ternary Laves phase isomorphous with MgCu_2 structure, no new intermediate phase has been found.In the Mo-Ti-Zr system the lattice parameter of the ternary solid solution increases with the increase...

The isothermal sections at 1200℃ of the systems Mo-Ti-Zr and Mo-Nb-Zr have been determined by metallographic and X-ray diffraction methods supplemented by hardness measurements. The constitutions of these two systems are strikingly similar; besides a b.c.c, ternary terminal solid solution and a ternary Laves phase isomorphous with MgCu_2 structure, no new intermediate phase has been found.In the Mo-Ti-Zr system the lattice parameter of the ternary solid solution increases with the increase of Ti or Zr in solid solution, and the ternary Laves phase is (Ti, Zr) Mo_2. In the Mo-Nb-Zr system, the lattice parameter of the ternary solid solution also increases with the increase in the Nb- or Zr-content, and the ternary phase in this case is Zr(Mo, Nb)_2.The iso-hardness contours of the Mo-Ti-Zr system tend to expand towards the titanium corner as the Ti-content is increased, whereas those of the Mo-Nb-Zr system expand towards the niobium corner with the increase in Nb-content in a like manner.

应用金相及X射线衍射方法,并辅之以硬度测量研究了Mo-Ti-Zr,Mo-Nb-Zr两三元系的1200℃恒温截面。两合金系统的1200℃恒温截面很相似,包括一个单相区α及一个两相区(α+ε)。在Mo-Ti-Zr系中α为体心立方Mo-Ti-Zr三元固溶体,其点阵常数随固溶体中钛、铅含量的增加而增大,ε为三元Laves相(Ti,Zr)Mo_2,其结构与ZrMo_2相同。在Mo-Nb-Zr系中α为体心立方Mo-Nb-Zr三元固溶体,其点阵常数也随固溶体中铌、锆含量增加而增加,ε为具有MgCu_2型结构的三元Laves相Zr(Mo,Nb)_2。在Mo-Ti-Zr三元系中,随着钛含量的增加,合金的等硬度曲线呈半环状向钛角扩展,在Mo-Nb-Zr三元系中,随着铌含量的增加,合金的等硬度曲线也呈半环状向铌角扩展。

An investigation of the thermal stability of titanium alloy TA8 (Ti-5Al-2.5Sn-3Cu-1.5Zr) showed that the embrittlement was closely related to the surface structures of the alloy. The formation process of such surface structures has been discussed. On account of the fact that oxygen diffuses into the matrix of the alloy during thermal exposure, the precipitation of Ti_2Cu and α-ordered phase in high oxygen solid-soluted surface and/or near surface layers may play an important role in causing the embrittlement...

An investigation of the thermal stability of titanium alloy TA8 (Ti-5Al-2.5Sn-3Cu-1.5Zr) showed that the embrittlement was closely related to the surface structures of the alloy. The formation process of such surface structures has been discussed.

本文报导了TA8(Ti-5Al-2.5Sn-3 Cu-1.5 Zr)合金热稳定性的研究结果,提出了表面结构的脆化机理,探讨了表面结构的形成。认为,在热暴露时,由于氧向基体的扩散作用,在含有高浓度固溶氧的表面或近表层中,Ti_2Cu和a有序相的析出,在合金脆化中起主要作用。

研究了合金元素Rb,Au,Mo,W,Zr,Hf对Pt的蠕变激活能的影响:Rh,Zr,Hf提高Pt的蠕变激活能;W,Mo,Au降低Pt的激活能。结合这些合金元素的特性,讨论了Pt合金的蠕变断裂机制。
