    The effects of rapid solidification on microstructure and hydrogen sorption properties of binary BCC Ti–V alloys
    摘要:
    The main purpose of the present work was to study the effect of rapid solidification (RS) on the microstructure and hydrogen storage properties of body centred cubic (BCC) Ti rich Ti-V alloys (Ti1-xVx, x = 0.1-0.3). Ribbons were prepared by melt spinning at spinner rotation velocities of 1000-3000 rpm. Ribbon morphology and microstructure were found to depend on the vanadium content and spinner velocity. For Ti0.8V0.2, the relation between the ribbon thickness and velocity can be expressed as a power law function, indicating that, during solidification of the Ti-V ribbons, heat transfer at the interface between spinner and ribbon controls the heat extraction. Temperature desorption spectroscopy (TDS) and in situ synchrotron (SR-XRD) studies of the RS alloys showed that hydrogen desorption from the RS alloy hydrides occurred at lower temperatures than from the as cast alloys. RS caused a microscale chemical element separation in the alloys, which depends on the vanadium content and the spinner velocity. In addition, ribbon recalescence was observed to cause nanoscale chemical redistribution trough spinodal decomposition. These two last features were proposed to be the reasons for the observed thermal destabilisation. (C) 2013 Elsevier B.V. All rights reserved.

    binary refractory concentrated alloy (RCA) systems, by measuring the atomic size misfit and the modulus misfit parameters and applying them to the Labusch and Suzuki SSH-based models. Interestingly, we find a general trend that increasing the portion of the atomic size misfit parameter provides a better estimation of the measured SSH, which is a noticeable feature of the edge dislocation mediated SSH
    固溶硬化 (SSH) 是提高合金强度的最简单方法之一,因为只有溶质的浓度才重要。最近有人提出,一些浓体心立方 (BCC) 合金中的 SSH 可能由边缘位错主导,这与先前提出的稀 BCC 合金的 SSH 理论不同。在这项研究中,我们通过测量原子尺寸失配和模量失配参数并将它们应用于基于 Labusch 和 Suzuki 的 SSH 模型,研究了 14 种二元耐火浓缩合金 (RCA) 系统中的主要 SSH 机制。有趣的是,我们发现了一个总体趋势,即增加原子尺寸失配参数的部分可以更好地估计测量的 SSH,这是边缘位错介导的 SSH 的一个显着特征。

    摘要 Ti 0.1 V 0.9 H x D y ( x + y ≈0.7) 合金已通过X 射线粉末衍射、差示扫描量热法(DSC) 和1 H 核磁共振(NMR) 进行了研究。富H样品和[H]/[D]=1样品的晶体结构在室温下为体心四方(bct),而富D样品的晶体结构为体心立方(密件抄送)。在除氢化物外的所有样品中,在 200-220 K 附近观察到类似于从 δ D 相到 α D 相的相变。在氢化物中,H 原子占据八面体 (O) 位点。在富含 H 的样品中,H 原子同时占据 O 和四面体 (T) 位点。在[H]/[D]=1的样品和富含D的样品中,H原子占据T位。1 H 自旋晶格弛豫时间 (T 1 ) 的温度和频率依赖性已通过改进的 Bloembergen-Purcell-Pound (BPP) 方程进行分析。O 位点的 H 扩散活化能高于 T 位点。氢化物的 D 添加和 Ti 的添加降低了 O

    Abstract The V 0.9 Ti 0.1 alloy absorbs a large amount of hydrogen, but it has never been used for the anode material for a Ni MH battery due to the poor discharge behavior in KOH electrolyte. V 0.9 Ti 0.1 alloy powder has been sintered with Ni powder to provide a catalytic effect on the absorption/desorption of hydrogen in KOH electrolyte. The optimal sintering condition was 5 min at 900°C and the
    摘要 V 0.9 Ti 0.1 合金吸收了大量的氢,但由于在KOH电解液中的放电性能差,它从未被用于镍氢电池的负极材料。V 0.9 Ti 0.1 合金粉末已与Ni 粉末烧结,以提供对KOH 电解液中氢的吸收/解吸的催化作用。最佳烧结条件是 900°C 下 5 分钟,改变镍粉的量以研究表面改性对放电特性的影响。所有用镍粉烧结的电极在 KOH 电解液中经过 10 次循环后完全活化。电极的放电容量随着烧结合金的 Ni 含量显示出最大行为。发现表现出最高放电容量 302 mA hg -1 的 Ni 粉末的最佳量为 25 wt.%。从扫描电子显微镜(能量色散光谱)和X射线等各种分析的结果发现,在烧结过程中形成了VNi 3 。在V 0.9 Ti 0.1 颗粒表面形成的VNi 3 相为电极提供了最佳放电容量。根据 Brewer-Engel 理论,发现 VNi 3 相具有高度的电催化性,这反映在交换电流密

    DOI:10.1039/c4cc02571g
    日期:——
    Vertically aligned titanium dioxide nanotube (TNT) arrays codoped with nitrogen and 3d transition metals were successfully fabricated using anodization and nitridation processes. The codoping of N and Fe yielded the highest visible-light-induced photoelectrochemical water oxidation due to bandgap narrowing of impurity levels by N and Fe.
