  Structural-thermodynamic method of phase analysis of multicomponent alloys based on the example of the Ni50Со25Мо25 alloy

  摘要：

  A structural-thermodynamic method of phase analysis of multicomponent alloys is proposed. The method is based on the use of the model of pairwise interaction and experimental determination of the sign of pairwise chemical interaction and includes an electron microscopic study of microstructures above and below the temperature of phase transition ordering-phase separation for each of the diffusion couples. The method is demonstrated on the example of the Ni50Co25Mo25 alloy. It is shown what precipitates are formed in the investigated alloy over the whole temperature range of heat treatment including the liquid state. We can conclude that structural data obtained in other works, for alloys, to some extent similar in composition to the alloy studied, are far from the results obtained in the present paper.

  of excess electrical energy in a power system to hydrogen through the use of water electrolysis is considered an effective alternative to replace fossil fuels. However, the scarcity and high cost of Pt-based materials for the hydrogen evolution reaction (HER) impedes their large-scale application in electric power systems. On the basis of the nanoscale Kirkendall effect, three-dimensional CoMoMg nanomeshes

  摘要 通过使用水电解将电力系统中多余的电能转化为氢气被认为是替代化石燃料的有效替代方法。然而，用于析氢反应（HER）的铂基材料的稀缺性和高成本阻碍了它们在电力系统中的大规模应用。在纳米级柯肯德尔效应的基础上，通过传统的高温烧结方法制备了三维 CoMoMg 纳米网。纳米网 CoMoMg 合金主要由金属间化合物 Co3Mo 组成，在 1 M KOH 中，在 10 mA cm-2 的电流密度下实现了 36 mV 的低过电位。该电极在不同电流密度（尤其是 2 A cm-2）下的 60,000 s HER 过程中显示出优异的长期稳定性，且不影响电催化活性，这归因于Co和Mo和三维纳米多孔结构之间的协同作用。该工作为设计高效耐用的析氢电催化剂提供了可行的策略，并有效解决了铂基贵金属催化剂昂贵的问题。

  The structures of the three η-carbides Ni6Mo6C, Co6Mo6C, and Co6Mo6C2, prepared by a new synthetic route, have been determined by Rietveld analyses of monochromatic neutron powder diffraction data. All three materials share the η-carbide structure-type with space group Fd3m (No. 227) and a = 10.8932(3) Å, a = 10.8998(2) Å, and a = 11.0709(3) Å, respectively. In the η-12 carbides, Ni6Mo6C and Co6Mo6C

  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.

  Phase structure and magnetic properties of the as-cast and as-milled/annealed SmCo(7-x)Mo(x) (x = 0, 0.1, 0.2, 0.3, 0.4) alloys have been systematically studied. It is found that all the as-cast series alloys are composed of the CaCu(5)-type and Th(2)Zn(17)-type phases. Saturation magnetization of the samples decreases with the Mo content increasing. Intrinsic coercivities ((i)H(c)) of no more than 0.06 T are observed in these as-cast samples, due to their rather coarse grain microstructures with an average grain size of 50 mm. The as-milled/annealed SmCo(7-x)Mo(x) powders crystallize in the disordered TbCu(7)-type (1:7) structure with very. ne nanograins, and a minor Co(3)Mo phase appears in the samples with x = 0.1-0.4. High iHc (>= 0.95 T) are achieved in these samples, with a maximum of 1.26 T located at x 0.2, which can be primarily attributed to strong pinning of the domain wall motion at the nanograin boundaries. The temperature coefficient (beta) of the iHc is about -0.22%/degrees C in the temperature range of 25-400 degrees C for the as-milled/annealed samples. (C) 2008 Elsevier B.V. All rights reserved.
