  Abstract The heat resistance of copper alloys is desirable to improve while it services at high temperature as electrically and thermally conductive components. In present paper, the strengthening pattern of nickel-based superalloys is expected to be applied in copper alloys. Here the Cu50Ni37.5M12.5 (M = Al, Cr, Mo) alloys were prepared by vacuum arc melting and heat-treated in the corresponding conditions

  摘要 铜合金作为导电导热元件在高温下使用时，需要提高其耐热性。在本文中，镍基高温合金的强化模式有望应用于铜合金。在此，Cu50Ni37.5M12.5 (M = Al, Cr, Mo) 合金通过真空电弧熔炼制备，并在相应条件下进行热处理，以获得三种不同的典型显微组织。对三种合金的室温（RT）性能（硬度和电阻率）和高温性能（熔点、软化温度和变温电阻率）进行了详细对比和分析。通过γ'相相干析出强化的Cu50Ni37.5Al12.5合金显示出最好的导电性和最高的硬度（5. 47 % IACS（国际退火铜标准）和 310.1 HV）。γ'相的分裂有助于在高时效温度下硬化。三种合金的电阻率-温度行为表明，随着温度升高的电阻率由理想的晶格电阻率和由于缺陷引起的电阻率增量组成。Cu50Ni37.5Al12.5合金室温电阻率最小，在整个加热过程中电阻率保持最低（RT-1077K）。因此，相干的沉淀γ'相有望

  MoNi4 was prepared by multi-step long-term thermal treatment. The crystal structure was re-evaluated by single-crystal and powder X-ray as well as powder neutron diffraction resulting in space group I4/m and lattice parameters of a=5.7300(6) Å and c=3.5649(6) Å. Despite the formation by complex solid-state reaction, the crystal structure of MoNi4 is fully ordered, whereby the single-crystalline micro-domains

  通过多步长期热处理制备单相MoNi 4 。通过单晶和粉末 X 射线以及粉末中子衍射重新评估晶体结构，得到空间群I 4/ m和晶格参数a = 5.7300(6) Å 和c = 3.5649(6) Å。尽管是通过复杂的固态反应形成的，但MoNi 4的晶体结构是完全有序的，单晶微畴的特征尺寸低于20μm。这种有序性得到了从 Mo 到 Ni 的强电荷转移的支持，阻碍了反位点的形成。两种类型的四原子键稳定晶体结构。该键合是各向同性的，允许在不同的晶体方向上裂解，表面上主要是镍原子。与镍物质的负有效电荷相结合，这使得我们能够更多地了解 MoNi 4在催化过程中的行为。

  Abstract Field-ion microscope observations were made on Ni 4 Mo alloy to investigate surface effects on ordering during in situ annealing after quenching from high temperature α phase region. Surface ordering occurred preferentially at 200} FCC and/or 111} FCC facets (at 880–835°C). Surface layers with low degree of order ranging from ten to a few tens angstroms in thickness were formed (at 760–720°C)

  摘要 采用场离子显微镜观察Ni 4 Mo 合金高温α相区淬火后原位退火过程中有序化的表面效应。表面排序优先发生在 200} FCC 和/或 111} FCC 面（880–835°C）。形成了厚度为十到几十埃的低有序度表面层（在 760-720°C 下）。相对较大的有序域中的有序度在表面附近（825-810°C）下降。在距表面 100-300 A 深度范围内的试样内部，有序行为与大块试样（825-720°C）的有序行为基本相同。同质成核有序结构域与样品内部（670°C）中相对较大的异质成核结构域共存。某些相对低指数 (FCC) 的平面（在 880-720°C 下）。源自β结构（有序结构）的刻面出现在表面（670°C）。此外，观察到原位形成的变形孪晶（在 810-825°C）。
• Carbothermic reduction of copper, nickel, and cobalt oxides and molybdates

  The carbothermic reduction of NiO, CoO, CuO, MoO3, and the MMoO4 (M = Ni, Co, Cu) molybdates has been studied by thermogravimetry. The results demonstrate that the reactivity of the molybdates with solid carbon, the sequence of reduction reactions, and the composition of reaction intermediates are determined by the reactivity of the constituent oxides, which decreases in the order CuO > MoO3 > NiO > CoO. The reaction intermediates in the reduction of CuMoO4 are Cu6Mo5O18 and Cu2Mo3O10, and those in the reduction of CoMoO4 are Co2Mo3O8 and CoMoO3. NiMoO4 is reduced without oxide intermediates. The reactions of CuMoO4 and NiMoO4 with solid carbon lead to selective reduction of the molybdates to metals (Cu or Ni) and molybdenum oxides (MoO2 and MoO3-x). In the reactions of NiMoO4 and CoMoO4 with CO gas, the metals are formed at comparable rates, which favors the formation of metal solid solutions, intermetallic phases, and mixed carbides.
