  Ti0.64Zr0.36Ni合金多晶型与氢化性能的关系

  摘要：

  摘要 研究了母晶结构对Ti 0.64 Zr 0.36 Ni合金氢化的影响。具有立方CsCl型结构的奥氏体Ti 0.64 Zr 0.36 Ni合金在氢化后保持其金属亚晶格结构。它通过 10.4% 的单元体积膨胀形成 Ti 0.64 Zr 0.36 NiH 1.6 氢化物（PH 2 = 1 MPa 和 T = 373 K）。相反，马氏体Ti 0.64 Zr 0.36 Ni合金的单斜TiNi型结构在吸氢后发生改性。在 PH 2 = 0.06 MPa 和 T = 373 K 时，两种氢化物与正交 CrB 型结构和成分 Ti 0.64 Zr 0.36 NiH 和 Ti 0.64 Zr 0.36 NiH 2.2 共存，分别导致细胞体积膨胀 5.36% 和 1% . 这些晶体结构的稳定性通过与其他 AB 金属间化合物（A = Ti、Zr、

  超冷合金中的相选择

  摘要：

  摘要 对于金属间二元和三元合金，过冷极限对晶体生长速度 v 作为过冷温度 Δ T 的函数的影响仍未得到解释。结合静电悬浮技术，我们在法国格勒诺布尔的欧洲同步辐射设施 (ESRF) 进行了原位高能同步加速器 X 射线衍射测量，以研究二元合金 NiTi、Zr 基的相形成三元合金 (NixCu1−x)Zr ( x = 0.3 , 0.4 ) 和 Ni 基三元合金 Ni ( Zr 0.5 Ti 0.5 ) 在过冷温度 Δ T Δ T hyp 和 Δ T > Δ T hyp 下的凝固事件，而 Δ T hyp 是系统的相应过冷极限。我们的结果表明立方 B2 型（CsCl 型，空间群 Pm3 m # 221 ) 相始终是所有研究合金的主要凝固相。这适用于所有获得的过冷度。因此，所有研究的合金在其超冷极限下的晶体生长速度中观察到的减速效应似乎是由与不同相的形成不同的原因引起的。

  multi-component AB2-type Laves phase in Ti–Zr–Ni (V, Cr, Fe, Mn, Co)ternary to octonary alloys system. To probe the formation and stability of AB2-type Laves phase in high-entropy alloys, a series of multi-component alloys have been synthesized via melting under protective Ar atmosphere and subsequent annealing at 525 K for 40 h. Systematic investigation has been carried out to understand phase stability using both

  摘要 本研究报告了多组分 AB2 型 Laves 相在 Ti-Zr-Ni（V、Cr、Fe、Mn、Co）三元至八元合金体系中的形成和稳定性。为了探测高熵合金中 AB2 型 Laves 相的形成和稳定性，通过在保护性 Ar 气氛下熔化并随后在 525 K 下退火 40 小时合成了一系列多组分合金。使用热力学和参数方法进行了系统研究以了解相稳定性。X 射线衍射测量和 Rietveld 分析表明在多组分合金中形成了 C14 Laves 相。混合焓（ΔHmix），已发现尺寸差异 (δ) 和价电子浓度 (VEC) 在控制这些合金中多组分 Laves 相的形成方面发挥着重要作用。价电子浓度和每原子电子比 (e/a) 决定了在这些高熵合金中稳定 Laves 相的元素选择。

From the data of different classes of systems, a unique relationship between melting entropy and melting viscosity has arisen in glass forming systems, which highlights the positive roles of low melting entropy on glass formation from a special perspective.

  到目前为止，关于熔化熵对玻璃形成的作用还没有达成共识。为此，对伪二元合金 Zr 2 Ni-Ti 2 Ni 的三种成分进行了研究，即共晶成分 (Zr 2 Ni) 0.206 (Ti 2 Ni) 0.794 , (Zr 2 Ni ) 0.654 (Ti 2 Ni) 0.346 , 莱夫斯化合物 (Zr 2 Ni) 0.44 (Ti 2 Ni) 0.56. 合金的熔化熵、熔化粘度和玻璃形成性的研究结果明确表明，低熔化熵和高熔化粘度有利于玻璃形成。从不同类别系统的数据来看，在玻璃成型系统中出现了熔化熵与熔化粘度之间的独特关系，从一个特殊的角度突出了低熔化熵对玻璃形成的积极作用。这项对热力学、动力学和玻璃形成的研究高度表明，熔化熵应作为设计金属玻璃的重要参考。
• An investigation of hydriding performance of Zr2−xTixNi (x=0.0, 0.3, 0.7, 1.0) alloys

  Zr2-xTixNi (x = 0.0, 0.3, 0.7, 1.0) alloys were prepared by arc melting method. The effect of Ti substitution in Zr site has been investigated in the perspective of both microstructural evolution and hydriding properties. The as-prepared Zr2Ni alloy exists as tetragonal C16 phase and Ti substituted alloys show mixed phase structure. The pressure-composition isotherms (PCI) revealed that with increase in Ti content, the equilibrium plateau pressure increases whereas the hydrogen uptake decreases. All the alloys absorb hydrogen without any incubation period. The rate of hydriding reaction decreases with incorporation of Ti and this is in agreement with the activation energy (Ea) values calculated using the modified KJMA model.

  The effect of Zr on the structure and electrochemical properties of nanocrystalline TiNi-type alloys was studied. These materials were prepared by mechanical alloying (MA) followed by annealing. It was found that the respective replacement of Ni in nanocrystalline TiNi by Zr, and by Zr and Fe improved not only the discharge capacity but also the cycle life of these electrodes. In the nanocrystalline TiNi0.875Zr0.125, a powder discharge capacity up to 135 mA h g(-1) was measured on the 10th cycle (at 40 mA g(-1) discharge current). The studies show that the electrochemical properties of Ni-MH batteries are a function of the microstructure and the chemical composition of the used electrode materials. (C) 2004 Elsevier B.V.

  Nanocrystalline TiNi1-xMx (M = Mg, Mn, Zr; x = 0, 0.125, 0.25) ternary alloys were prepared by mechanical alloying (MA) followed by annealing. The effect of Mg, Mn and Zr on the structure and electrochemical properties of nanocrystalline TiNi-type alloys was studied. It was found that the respective replacement of Ni in TiNi by Mg, Mn or Zr improved not only the discharge capacity but also the cycle life of these electrodes. In the nanocrystalline TiNi0.875Mn0.125 powder the discharge capacity up to 151 mA h g(-1) on the 10th cycle was measured (at 40 mA g(-1) discharge current). The studies show, that the electrochemical properties of nanocrystalline MH electrodes are a function of the chemical composition of the used materials. The band structure has been studied by the Tight Binding version of the Linear Muffin-Tin orbitals method in the Atomic Sphere Approximation (TB LMTO ASA). (c) 2005 Elsevier B.V. All rights reserved.
