  Synthesis and structure determination of a new series of hydrogen storage alloys; RMg2Ni9 (R=La, Ce, Pr, Nd, Sm and Gd) built from MgNi2 Laves-type layers alternating with AB5 layers

  摘要：

  A number of new ternary magnesium based alloys, RMg2Ni9 (where R=La, Ce, Pr, Nd, Sm and Gd), have been synthesized by reacting a mixture of MgNi2 with RNi5 intermetallic compounds or by direct combination of the elements in the atomic ratio R:Mg:Ni=1:2:9. The crystal structure, determined by Guinier-Hagg X-ray powder diffraction, is related to the hexagonal PuNi3 type. All interatomic distances are close to the corresponding ones in (C-15) MgCu2, (C-14) MgZn2, (C-36) MgNi2, RNi3 and RNi5 of metallic-type bonding. (C) 1997 Elsevier Science S.A.

• Cocktail effect on RT5-type (R = rare earth, T = 3d transition metal) high entropy intermetallic compounds

  intermetallic compounds due to their single-phase characteristics and high configuration entropy. The magnetic cocktail effect is observed in magnetic measurements. These intermetallic compounds show low-temperature magnetic transition and field-induced ferromagnetic characteristics. The cocktail effect is suggested to be modulated by the spins with random directions at rare earth and transition metal sublattices

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

  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.
