  熔融 LiCl-KCl-PrCl[sub 3] 体系中 Pr-Ni 合金的电化学形成和相控制

  摘要：

  在 723 K 的熔融 LiCl-KCl-PrCl 3 (0.50 mol %) 系统中研究了 Pr-Ni 合金的电化学形成。通过恒电位电解在 0.50 V 下在 Ni 电极上快速形成连贯且致密的 PrNi 2 膜。使用薄Ni电极（50μm），在整个电极变成PrNi 2 后在0.50V下形成PrNi。形成的PrNi 2 电极通过电化学置换转变为其他相，即PrNi 3 、Pr 2 Ni 7 、PrNi 5 和Ni。阐明了合金的形成反应和相应的平衡电位。从使用透射电子显微镜和电子衍射的形态学和晶体学研究来看，已经表明快速 PrNi 2 形成是由于晶界内和附近的高 Pr 扩散率。

• Experimental investigation and thermodynamic modeling of the Ni–Pr system
  作者：Mianliang Huang、Thomas A. Lograsso

  日期：2005.5

  The Ni-Pr system is investigated via experiments and thermodynamic modeling. In the experimental part, five alloys with compositions of Ni-96 at.% Pr, Ni-85 at.% Pr, Ni3Pr, Ni5Pr and Ni-5 at.% Pr were prepared by arc melting pure Ni and Pr slugs and annealing the alloys at 500 degrees C for 2 weeks. The annealed alloys were then subjected to differential thermal analysis (DTA) measurements. The decomposition temperatures of Ni7Pr, (1162 degrees C), Ni3Pr (1029 degrees C), Ni2Pr (921 degrees C), dhcp (Pr) (780 degrees C), the cutectic reaction temperature of liquid <-> fcc (Ni) + Ni5Pr (1280 degrees C) and the congruent melting point of Ni5Pr (1385 degrees C) were determined by DTA, respectively. In the modeling part, the available phase equilibrium and thermodynamic data in the Ni-Pr system were analyzed by using thermodynamic models for the Gibbs energies of individual phases. An optimal set of thermodynamic parameters was obtained using WinPhad software. The calculated phase equilibria and thermodynamic properties from the model parameters were compared to the corresponding experimental data and good agreement was obtained. (c) 2004 Elsevier B.V.

  The isothermal section at 773 K of the phase diagram of Pr-Fe-Ni system was investigated by X-ray powder diffraction and scanning electron microscopy equipped with energy dispersive spectroscopy. The isothermal section consists of 11 single phase regions, 19 two-phase regions and 9 three-phase regions. The maximum solid solubilities of Fe in Ni, PrNi5, Pr2Ni7, PrNi3, PrNi2, Pr7Ni3 and Pr3Ni are about 80.0, 18.2, 15.4, 11.8, 1.9, 1.7 and 4.4 at%, respectively. The maximum solid solubilities of Ni in Fe and Pr2Fe17 are about 5.0 and 1.2 at%, respectively. The solid solubility of Fe in PrNi phase is negligible. The influence of Fe substitution on the microwave absorbing properties of the PrNi5 alloy was investigated. The frequency corresponding to the minimum absorption peak of Pr16.67Ni83.33-xFex (x = 0.0-17.5) shifts towards higher frequency region upon the Fe substitution. The Pr16.67Ni68.33Fe15.0 alloy exhibits the best microwave absorption properties. The minimum reflection loss of Pr16.67Ni68.33Fe15.0 powder is -35.10 dB at 9.76 GHz, and the frequency bandwidth of reflection loss smaller than -10 dB reaches about 1.60 GHz with the best matching thickness of 1.5 mm.
