    溅射近等原子 NiTi 形状记忆薄膜退火过程中引起的结构和缺陷
    摘要:
    在通过射频磁控溅射制备的自支撑 NiTi 薄膜中研究了退火过程中引起的结构和缺陷。Ni4Ti3 与 (B2) 基体相结合的沉淀不会影响在 550°C 下短时间退火的薄膜的形状记忆行为。随着退火时间和/或温度的进一步增加,不连贯的 Ni4Ti3 析出物会形成并阻碍形状记忆行为。退火薄膜的脆化可能是由晶界沉淀、热蚀刻和应力梯度引起的。

    Production of NiTi shape memory alloys via electro-deoxidation utilizing an inert anode
    摘要:
    NiTi shape memory alloys (SMA) with equiatomic composition of Ni and Ti were prepared by electro-deoxidation, in molten calcium chloride, at 950 degrees C. Constant voltage electro-deoxidation was conducted using a NiTiO(3) cathode, and either a carbon anode or a novel CaRuO(3)/CaTiO(3) composite inert anode. Both anode materials successfully allowed NiTi shape memory alloy to be obtained. The primary difference is that molecular oxygen was produced on the inert anode, instead of environmentally undesired CO(2) greenhouse gases on the carbon anode. Indeed, it was found that carbon could successfully be substituted with conductive calcium titanate-calcium ruthenate composites for electro-deoxidation. Furthermore. DSC was used to analyze the phase transformation of NiTi shape memory alloys, with results revealing the existence of reversible martensite-austenite phase transformations during the cooling and heating process.

    heat of formation of an intermetallic and the milling energy required for its formation during mechanical alloying. This has been demonstrated in case of B2 intermetallic compounds, namely, NiAl, FeAl, CoAl and MnAl. The milling energy corresponding to the start of formation of the compounds during mechanical alloying of the elemental blends is found to decrease linearly with the heat of formation of the
    摘要 本文试图得出金属间化合物的形成热与其在机械合金化过程中形成所需的铣削能量之间的关系。这已经在 B2 金属间化合物,即 NiAl、FeAl、CoAl 和 MnAl 的情况下得到证明。发现与元素混合物的机械合金化过程中化合物开始形成相对应的研磨能量随着金属间化合物的形成热而线性降低,使用 Miedema 模型计算。还合成了 Al 3 Zr、Ni 3 Al、Ni 3 Mn、CoFe、NiTi、Zr 3 Co,以尝试在更广泛的化合物范围内以及混合焓测试假设的强度。已尝试了解化合物形成的机制。

    for which few additions have been obtained, probably due to the understanding being confounded by other impurity phases. This alteration intrinsically results in enhanced desorption properties of Mg2NiH4 when Ti is dissolved, i.e., not only does it exhibit a decreased peak desorption temperature with a reduction in the activation energy, but it also positively changes the enthalpy value in comparison
    在低温下实现快速氢解吸是储氢中Mg基合金的主要挑战之一。在这里,我们报告说,通过将钛固溶到其晶格中,可以本质上改善Mg 2 NiH 4的脱氢过程。根据动力学模型研究,建议通过将限速步骤从已证明的成核和/或扩散转变为二维相边界迁移来促进氢解吸,但由于了解有限,可能没有获得更多的结果。通过其他杂质相。当钛溶解时,这种改变本质上导致Mg 2 NiH 4的解吸性能增强,即,它不仅显示出降低的峰值解吸温度,并降低了活化能,而且与纯化合物相比,其焓值也发生了积极变化。这些获得的结果可以使人们对固体溶解如何增强固有的脱附特征有更深入的了解,并且还可以为改善镁基合金中的氢存储提供见识。

    Abstract An Electro-Assisted Powder Metallurgical (EPM) route is able to prepare porous NiTi alloys with controllable porosities and pore sizes using nickel (Ni) and titanium (Ti) powders at a temperature ranging from 850 to 950 °C. Ammonium hydrogen carbonate (NH4HCO3) was used as a sacrificial space holder to tailor the porosity and pore size of the NiTi alloy and its properties, i.e., elastic modulus

    The phase equilibria of the Ti–Ni–Sn and Ti–Ni–Sb ternary systems have been studied in the whole concentration range by means of X-ray and EPM analyses at 1073 K and 873 K, respectively. Four ternary intermetallic compounds TiNiSn (MgAgAs-type), TiNi2−xSn (MnCu2Al-type), Ti2Ni2Sn (U2Pt2Sn-type), and Ti5NiSn3 (Hf5CuSn3-type) are formed in Ti–Ni–Sn system at 1073 K. The TiNi2Sn stannide is characterized
