Journal description

The aim of the Journal of Alloys and Compounds is identical to the journal's aim under its previous title: Journal of the Less-Common Metals. The journal was originally intended to serve as an international medium for the publication of work on the physical sciences of usually called less-common-metals, their compounds and their alloys. Its great strength lies in the diversity of discipline which it encompasses, drawing together results from materials science, solid-state chemistry and physics. The interdisciplinary nature of the journal is evident in many subject areas. Experimental and theoretical approaches to materials problems require an active interplay between a variety of traditional and novel scientific disciplines. In much of the work published in the journal, synthetic and structural studies are combined with investigations of chemical and physical properties of alloys and compounds, contributing to the development of areas of current scientific interest. The Journal of Alloys and Compounds provides a unique international forum where materials scientists, chemists and physicists can present their results both to workers in their own fields and to others active in related areas.

    ABSTRACT: Simple high-valent iron-oxo species, ferrate(VI) (FeVIO42−, Fe(VI)) has applications in energy storage, organic synthesis, and water purification. Of the various salts of Fe(VI), barium ferrate(VI) (BaFeOr4) has also a great potential as a battery material. This paper presents the thermal decomposition of BaFeO4 in static air and nitrogen atmosphere, monitored by combination of thermal analysis, Mössbauer spectroscopy, X-ray powder diffraction, and electron-microscopic techniques. The formation of FeIV species in the form of BaFeO3 was found to be the primary decomposition product of BaFeO4 at temperature around 190°C under both studied atmospheres. BaFeO3 was unstable in air reacting with CO2 to form barium carbonate and speromagnetic amorphous iron(III) oxide nanoparticles (<5 nm). Above 600°C, a solid state reaction between BaCO3 and Fe2 O3 occurred, leading to the formation of barium ferrite nanoparticles, BaFe2 O4 (20-100 nm).

    ABSTRACT: This paper describes a facile route for the preparation of visible-light-active N-doped TiO2 nanorods arrays at low temperature by a template-free oxidant peroxide method (OPM) and crystallized under hydrothermal treatment. The samples were characterized for structural, morphological and optical properties by XPS, FE-SEM, HRTEM, XRD, Raman and UV–vis spectroscopy. XPS analysis revealed that N dopant atoms were mainly added at the interstitial sites into TiO2 lattice structure and few N atoms were present as substitutional sites of nitrogen atoms and/or at molecularly chemisorbed γ-N2 molecules. FE-SEM and HR-TEM analyses show that doping does not influenced the cylindrical architecture of the nanorods. However, N doping causes an obvious red shift in the band edge which increases visible region absorption. The photocatalytic activity of pristine and N-doped TiO2 photocatalysts was tested for the degradation of methyl orange (MO) under UV and visible light irradiation. The N-doped TiO2 photocatalysts showed an efficient photocatalytic activity for methyl orange degradation under UV and visible-light irradiation as compared to pristine TiO2. Multiple cycles for the MO photodegradation were performed without a decrease in the photocatalytic activity. PEC studies showed that photocurrent densities of 8.2 μA cm−2 and 7.0 μA cm−2 were obtained under UV and visible-light illumination at a potential of 0.8 V.

    ABSTRACT: Ductility enhancement up to about 28–39% in fracture elongation with simultaneous strengthening was achieved in fine-grained magnesium and magnesium alloy sheets by multi-pass rolling with lowered temperature suitable for industrial fabrication. Specifically, high strengths at yielding following slip-dominated Hall–Petch relations were achieved owning to the naturally twinning's replacement by pyramidal<c+a> under intense basal texture. These Hall–Petch relations had a high slope of 190 MPa μm1/2 and frictional stresses ranging from 40 MPa to 144 MPa. The variation in frictional stress matched well with solid solution hardening and/or precipitation hardening. Enhanced uniform elongation was strongly correlated with improved strain-hardening rate via introducing solid solution and/or fine precipitates in Mg alloys compared with pure Mg, and conversely post-necking elongation (local elongation) as well as cold-workability under compressive stress was strikingly weakened by the restriction of dynamic recovery.

    ABSTRACT: Microstructure and tensile properties of a new α/β Ti–47Zr–5Al–3V (wt%) alloy are investigated in the present study. Both α/β and β thermal annealing at 650 °C–800 °C for 1 h and subsequent aging at 450 °C for 2 h are introduced to investigate the effect of thermal annealing and aging on the microstructure and tensile properties of the Ti–47Zr–5Al–3V alloy after cold rolling. After thermal annealing, a fully equiaxed microstructure, a bi-modal microstructure and a fully lamellar microstructure are obtained with increasing the annealing temperature (650–800 °C), respectively. The 450 °C/2 h aging leads to further precipitation of extremely fine α platelets from the annealed samples. With increasing the annealing temperature, the tensile strength (σb) of annealed samples increases gradually from ∼1350 to 1420 MPa, whereas the elongation to failure (εf) first increases and then decreases and the highest εf ∼10.6% is attained at 750 °C. For all annealed samples, the 450 °C/2 h aging leads to increased strength and decreased ductility and the 750 °C/1 h annealing plus 450 °C/2 h aging results in the best combination of ultrahigh strength (σb ∼1510 MPa) and good ductility (εf ∼9.3%). The ultrahigh strength results from the strengthening of fine secondary α platelets, while the good ductility is attributed to the formation of large primary αp grains and the fine β grain size.

    ABSTRACT: Metal-Ceramic composites possess remarkable mechanical properties and chemical stability, but suffer from brittleness. Here, we prepare laminated Ti/Al2O3 composite via tap-casting and hot-press sintering at 1500 °C with an applied pressure of 30 MPa for 1.5 h to improve its mechanical performance. Compact laminated structure and crack deflections emerged in a distinct interfacial region were observed. The EDS and XRD results demonstrate that aluminum (Al) and oxygen (O) elements transmit through the interface to titanium (Ti) layers and react with Ti to form Al–Ti intermetallic compounds, titanium oxides and solid solutions of Al–Ti–O. Meanwhile, triple junction boundary emerging in interface is evaluated by Zener's relation. Finally, the schematic illustration of microstructure evolution indicates that the hybrid fracture mode (e.g. trans-granular fracture, inter-granular fracture and the co-existing mode) results in the crack deflection. Owing to this hybrid fracture method, the laminated Ti/Al2O3 composite invariably performs better performance than monolithic composite.

    ABSTRACT: Due to the exhaustion of rare metal resources and the hazard of toxic material to the environment, development of cost-effective, nontoxic, and earth-abundant thermoelectric materials has become more urgent. This study introduces a nontoxic, earth abundant n-type iron-based cost-effective Fe–2.3C–Si–5Mn–7V–8Cr thermoelectric material that is prepared by a simple melting method. Significant increase in both electrical conductivity and Seebeck coefficient are achieved by several heat treatment processes to optimize the distribution and grain size of VC, Cr23-xFexC6 typed chromium carbide as well as base matrix. As a result, the power factor of the sample that is normalized at 1150 °C is about 0.75 mWm−1K −2 in maximum value, which is 2.6 times larger than that (0.29 mWm−1K−2) of as-cast sample. The highest ZT value of the sample that is normalized at 1150 °C is 0.028 at 868 K, which is 4.3 times larger than that of as-cast sample (0.0065 at 964 K) in present study, indicating that a proper heat treatment process would remarkably enhance ZT value. This research provides extremely valuable data for the future researches on thermoelectric alloys.

    ABSTRACT: Sonication-assisted interfacial self-assembly of tiny GO sheets (whose lateral size less than 200 nm) on cationic polyelectrolyte-decorated SiO2 microspheres was achieved, leading to the formation of uniform GO thin layer coated SiO2 microspheres (i.e., SiO2/GO composite microspheres), which possessed high aqueous dispersity. RGO/TiO2 composite hollow microspheres were further one-pot synthesized by solvothermal treatment of SiO2/GO microspheres in the presence of polyvinylpyrrolidone (PVP) using TiF4 as Ti precursor and ethanol/water as a mixed solvent. It was found that PVP and appropriate volume ratio of ethanol to water (v/v = 20:8) were key factors for the fabrication of RGO/TiO2 hollow microspheres with well-defined microspherical hollow structure. The composition, morphology, structure and crystalline phase of RGO/TiO2 hollow microspheres were carefully examined by a series of characterizations like FTIR, UV–vis and Raman spectroscopy as well as XRD, SEM and TEM inspections. Compared with the solvothermally synthesized TiO2 hollow microspheres and blended RGO−TiO2 hollow microspheres, RGO/TiO2 hollow microspheres displayed rather enhanced photocatalytic performance toward the degradation of methylene blue. Moreover, RGO/TiO2 hollow microspheres were durable and robust enough so that they were able to be reused for many times with only a little loss of photocatalytic activity and without the destruction of morphology and structure, exhibiting prominent application potential. This work reveals a facile and versatile synthetic methodology for the fabrication of advanced GO- and RGO-containing hybrid materials with unique shapes and designed properties.

    ABSTRACT: CeO2:Er3+ films were deposited by electron-beam evaporation technique. Photoluminescence properties of Er3+ doped CeO2 films annealed in air atmosphere were investigated. Visible and near-infrared emission peaks were assigned to the transitions from 2H11/2, 4S3/2, 4F9/2, 4I11/2 and 4I13/2 levels to 4I15/2 level, respectively. The structure and the luminescent properties of CeO2:Er3+ films were characterized by X-ray diffraction, photoluminescence and photoluminescence excitation spectra. In addition, luminescence intensities of Er3+ and the intensity ratio of red/green emission peaks were also investigated. They were strong affected by the doping concentration of Er3+. With the good luminescent properties, CeO2:Er3+ films should be promising candidates for multifunctional applications.

    ABSTRACT: A novel Ca5Y3Na2(PO4)5(SiO4)F2 compound with apatite structure was synthesized by solid state reaction method. The crystal structure was characterized by X-ray diffraction and refined with Rietveld refinements. The luminescence properties of Ca5Y3Na2(PO4)5(SiO4)F2:Eu phosphors were also investigated. The results indicated that the Ca5Y3Na2(PO4)5(SiO4)F2:Eu phosphors prepared in reducing atmosphere contained both Eu2+ and Eu3+ ions, which could be identified from their characteristic emissions. Upon UV light excitation, the emission spectrum including an asymmetric broad band of Eu2+ and several peaks of Eu3+ covered blue and red light regions, matched well with the spectrum required for plant growth. Thermal stability property was also investigated, and the results showed that Ca5Y3Na2(PO4)5(SiO4)F2:Eu exhibited good thermal stability. The luminescence spectra and time-resolved emission spectra indicated that there was no energy transfer between Eu2+ and Eu3+.

    ABSTRACT: Electronic structure of Cr, Mn, Fe, and Co transition metal (TM) ions in GaN and AlN is studied within the Generalized Gradient Approximation augmented by the +U corrections, which are treated as free parameters. The main impact of U(N) is the opening of the band gap by shifting both valence and conduction band energies. The intracenter transitions between the gap states of TM impurities are weakly affected by U(N), but they are sensitive to U(TM) which directly act on d(TM) orbitals. The impact of U(TM) depends on both the level symmetry and its occupancy (i.e., on the charge state of the TM ions). Degeneracies of partially occupied multiplet levels are lifted, the effect being mainly driven by the +U correction and not by the Jahn-Teller mechanism. The role of the U-induced hybridization between TM and host states is elucidated.

    ABSTRACT: The total energies and forces of the Ba0.5La0.5Fe11.5Cu0.5O19 structure were calculated using the density functional theory (DFT) and generalized gradient approximation (GGA). The calculations demonstrated that at 0 K, the magnetic ions Cu2+ preferentially occupy Fe3+ at the 4f2(0) and 4f2(1) configurations. For the site occupancy at the higher temperature (0–1500 K, except 0 K), we computed the formation probability of twenty inequivalent configurations using the Maxwell–Boltzmann statistical distribution. Correspondingly, the Cu2+ ions prefer to enter the 4f2 and 2b sites, especially close to lanthanum layer. In order to confirm the computational conclusions, La–Cu substituted barium hexaferrites with the chemical formula of Ba1−xLaxFe12−xCuxO19 (x = 0.0, 0.1, 0.3, and 0.5), prepared by a conventional ceramic method, were investigated by the Raman spectra and Rietveld refinement of X-ray diffraction patterns (XRD). The experiments revealed that the Cu2+ ions are partitioned at the 2b and 4f2 sites in the ratio of around 1:2.

    ABSTRACT: In this work the plasmonic photocatalytic activity of ZnO/noble metals nanocomposites has been investigated. Ag nanowires and Au nanospheres were prepared and mixed with ZnO in order to prepare the nanocomposites. It was demonstrated that the composites containing the plasmonic Ag nanowires and ZnO nanoparticles showed a significant photocatalytic activity enhancement compared to the pure ZnO in decomposition of methylene blue (MB). By investigation of mechanisms governing the performance of plasmonic photocatalysts, it was found that the photocatalytic activity enhancement can be attributed to the energy transfer from Ag nanowires to the ZnO nanoparticles induced by the surface plasmonic resonance (SPR). Such energy transfer is due to increasing the average path length of the photons in the composite and the SPR-induced local electromagnetic field near the surface of Ag nanowires. This mechanism predicts an enhancement in the concentration of charge carriers at the semiconductor surface by which the photocatalytic activity improves. The results showed that the photocatalytic activity enhancement was depended on the diameter size and concentration of Ag nanowires in the composites. Our studies showed that the composite containing 4.5 wt % of Ag nanowires with mean diameter size of 280 nm exhibited the highest photocatalytic activity enhancement compared to the pure ZnO nanoparticles. Furthermore, ZnO/Au nanospheres composite presented a little enhancement in photocatalytic activity compared to the composites containing Ag nanowires.

    ABSTRACT: Nanostructured graphene/Bi2Te3 composites were fabricated with either Bi2Te3 powder or nanowires (NWs) and various graphene contents, and their thermoelectric properties were investigated. The Bi2Te3 powder was produced from Bi2Te3 beads with a conventional ball milling process, whereas the Bi2Te3 NWs were fabricated with a solution-phase synthetic route. The composites with a graphene content of 0.5 wt.% exhibited enhanced power factors, presumably because of an improvement in the Seebeck coefficients of the samples, which overwhelmed the reduction in electrical conductivity. In addition, the introduction of graphene reduced the lattice thermal conductivity of the composites because it caused the formation of many boundaries in the Bi2Te3 matrix. The maximum thermoelectric figure of merit (ZT) of 0.4 was achieved at 300 K with the 1 wt.%-graphene/Bi2Te3-NW composite; it was larger than that of the pristine Bi2Te3 NWs and graphene/Bi2Te3-powder composites.
