  Vibrational entropy and microstructural effects on the thermodynamics of partially disordered and orderedNi3V

  摘要：

  Samples of Ni3V were prepared with two microstructures: (1) with equilibrium D0(22) order, and (2) with partial disorder (having a large D0(22) chemical order parameter, but without the tetragonality of the unit cell). For both materials, we measured the difference in their heat capacities from 60 to 325 K, inelastic neutron-scattering spectra at four values of Q at 11 and at 300 K, and Young's moduli and coefficients of thermal expansion. The difference in heat capacity at low temperatures was consistent with a harmonic model using the phonon density of states (DOS) curves determined from the inelastic neutron-scattering spectra. In contrast, at temperatures greater than 160 K the difference in heat capacity did not approach zero, as expected of harmonic behavior. The temperature dependence of the phonon DOS can be used to approximately account for the anharmonic contributions to the differential heat capacity. We also argue that some of the anharmonic behavior should originate with a microstructural contribution to the heat capacity involving anisotropic thermal contractions of the D0(22) structure. We estimate the difference in vibrational entropy between partially disordered and ordered Ni3V to be S-pdis-S-ord=(+0.038+/-0.015)k(B)/atom at 300 K.

• Phase equilibria in the V-Ni-Sb system

  Phase relations in the V-Ni-Sb system have been studied by x-ray diffraction, and the 1070-K section of its phase diagram has been constructed in the region 0-67 at % Sb. The VSb phase (NiAs structure) is shown to have a homogeneity range: V1.04-1.00Sb0.96-1.00 (a = 0.4274(1)-0.4266(2) nm, c = 0.5464(2)-0.5448(4) nm). The binary antimonides with the NiAs structure dissolve the third component. V solubility in NiSb is within 3.5 at %. Ni dissolution in VSb is accompanied by partial Ni substitution for V and Ni incorporation into position 2d of space group P6(3)/mmc, up to the composition V0.84Ni0.32Sb0.84 (a = 0.42187(6) nm, c = 0.54000(9) nm).

  The isothermal section of the phase diagram of the ternary system Y-Ni-V at 773 K was investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersion spectroscopy (EDS) techniques. It consists of 16 single-phase regions, 29 two-phase regions and 14 three-phase regions. At 773 K, the maximum solid solubility of V in Ni, Y2Ni17, YNi5, Y2Ni7, YNi3, and YNi2, is about 17, 1, 2, 2, 2 and 2 at.%, while Y in Ni, Ni3V, Ni2V, Ni2V3, NiV3 and V does not exceed 1 at.%. No ternary compound has been observed in this work. (c) 2008 Published by Elsevier B.V.
