• On the partial atomic volume and the partial molar enthalpy of aluminium in some phases with Cu and Cu3Au structures

  日期：1991.6

  The lattice parameters and macroscopic densities of the solid solutions of Co(Al), Rh(Al), Ir(Al), Ni(Al), Cu(Al), Ag(Al) and Au(Al) and the intermetallic compounds of Ni3AI and Ag2Al were measured over the whole range of homogeneity. The dependence of both the average atomic volume and the enthalpy of formation on mole fraction was investigated for the systems A9-Al (A9 = Co, Rh, Ir), A1O-Al (A10 = Ni, Pd, Pt) and B11-Al (B11 = Cu, Ag, Au). The partial atomic volume and the partial molar enthalpy of aluminium were analysed for phases with the Cu and CU3Au structures. Among the quasi-homological systems, the smallest values for the partial atomic volume of aluminium and the most negative values for the partial molar enthalpy of aluminium were found in the solid solutions A10' (Al). These indicate a strong charge transfer from aluminium-atoms to atoms of nickel, palladium and platinum.

  AbstractThe rare-earth metal-rich RE14T3Al3 series (RE = Y, Gd–Tm, Lu) was extended to the transition metals T = Cu, Rh, and Pd. All compounds have been prepared by arc-melting the rare-earth elements with appropriate amounts of TAl precursors. The compounds crystallize in the tetragonal Gd14Co3In2.7-type structure with space group P42/nmc. Two structures (Y14Rh2.97(1)Al3.03(1): a = 952.99(4) pm, c = 2292

• Band engineering in Al-TM (TM=Rh, Ir) quasicrystalline approximants via alloying and enhancement of thermoelectric properties

  The binary Al-Ir 1/0 quasicrystalline approximant is predicted to be a narrow band gap semiconductor with a large Seebeck coefficient; however, it has not yet been realized practically because the presence of Al vacancies causes excess hole doping, which results in a small Seebeck coefficient. Here, we synthesized and measured the true density, lattice constant, and thermoelectric properties of Al-(Rh,Ir) quasicrystalline approximants with a series of Al-73(.3)(RhxIr1-x)(26.7) (x = 0, 0.25, 0.5, 0.75,1.0) compositions. The number of atoms per unit cell calculated using the true density, nominal composition, and lattice parameter increased with increasing Rh content x. The compositional dependence of the Seebeck co-efficient and dimensionless figure of merit zT showed a maximum value at x = 0.25, 850 K. The results indicated that Rh doping could effectively suppress Al vacancies, and the width of the band gap decreased with increasing x. In other word, a trade-off was observed between the amount of Al vacancies and the width of the band gap between the Al-Ir and Al-Rh 1/0 quasicrystalline approximants. (C) 2020 Elsevier B.V.
