Journal of Alloys and Compounds Impact Factor & Information

Publisher: Elsevier

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: We report a facile, rapid and low-cost two step approach to synthesize hierarchical CuO@MnO2 core–shell nanosheet arrays directly on Cu foil substrate. The as prepared CuO@MnO2 arrays can be directly used as integrated electrodes. Furthermore, the CuO@MnO2 nanosheet arrays were assembled with the commercial Li Ion Battery Cathode (LiCoO2) as a full cell, which exhibited high capacity and good cycle stability (120 mA h g−1 after 100 cycles at a rate of 150 mA g−1) and an excellent rate performance (a stable capacity of about 127 mA h g−1 after 100 cycles of variable charging rate). The excellent performance of the CuO@MnO2 hybrids comes from their intelligent integration of the two compatible components into unique hierarchical architectures with a high specific capacity. Primary single-crystalline CuO nanosheet arrays directly grown on Cu substrates allow for efficient electrical and ionic transport. The secondary MnO2 shell provide enhanced surface area and high theoretical Li+ storage capacity, and can also serve as volume spacers between neighboring CuO nanosheet arrays to maintain electrolyte penetration as well as reduce the aggregation during Li+ intercalation, thus leading to improved electrochemical energy storage performance.

    ABSTRACT: Electrochemical reduction of silicon on metal electrodes in molten silicate was studied. An iron sheet was immersed in SiO2–Li2O–MgO at 1273 K, and the electrode potential was controlled for 1 h. Formation on the iron of a Si-containing layer about 10–30 μm thick was observed after the electrolysis, depending on the potential. When a molybdenum electrode was used, α-MoSi2 layer about 5 μm thick was formed on the surface. The results suggest the applicability of molten oxide electrolysis as a synthesis method of Si-containing alloy layers.

    ABSTRACT: Visible-light-absorbing compounds that generate reactive oxygen species in water are needed to maximize the degradation rate of organic dye under incident solar radiation. In this study, hollow ZnFe2O4 and ZnFe2O4/TiO2 composites were prepared by coprecipitation and microemulsion method, respectively. The structure and morphology of as-prepared samples as well as their magnetic properties and photocatalytic degradation activities on methyl orange and rhodamine B solution were investigated in detail. The results show that ZnFe2O4/TiO2 composites have excellent performance on photocatalytic degradation of dye in wastewater under visible light. Especially, the photocatalytic degradation activity of the composite with 25% on dye in wastewater was comparable to that of pure titanium dioxide (under UV light). Also, all samples show good stability, and are easy to recycle. This work demonstrates a cost-effective, recyclable, environment-friendly and simple way to directly degrade organic dye in wastewater by means of photocatalysis.

    ABSTRACT: Solid solutions in the Ca8−xSrxBi2(PO4)6O2 system were synthesized using the solid-state reaction method. The structures were refined by Fullproof program which is based on Rietveld method formalism. The Sr2+ ions were noted to occupy two sites (4f) and (6h), with a strong preference for (6h) sites. The heavy atoms Bi3+ preferentially occupied the (6h) site. The charge distributions (CD) (through CHARDI-it method) were used to validate the structures. The frequencies observed in the Raman and infrared spectra were explained and discussed and comparisons with Fluoroapatites and other oxyapatites. The electrical properties of the samples were also studied by the complex impedance method between 600 and 725 °C. The results revealed that electrical conductivity increased with increasing strontium content.

    ABSTRACT: The magnetic and magnetocaloric properties of alloy has been investigated by using of electron microscopy, X-ray diffraction, calorimetric, heat capacity and magnetic measurements. The substitution of Fe atoms for Mn atoms in the CoMnGe system leads to a decrease in the martensitic transition temperature from 650 K to room temperature (RT) and presents the magnetostructural properties in vicinity of RT. In order to assess MCE, temperature dependent of magnetization measurements have performed under applying variable magnetic fields. The largest entropy change values are −34.9 J kg−1 K−1 (magnetization) and −33.6 J kg−1 K −1 (demagnetization) for . The adiabatic temperature change value of is calculated 8.5 K for 2 T from magnetic and heat capacity measurements. The density of states of electrons at Fermi level and the Debye temperature values of this alloy are found 1.19 states eV−1 atom−1 and 353 K from low temperature heat capacity measurements. This giant magnetocaloric effect makes this material a very promising candidate for future RT cooling applications.

    ABSTRACT: Bulk nanostructured higher manganese silicide (HMS) samples with different grain size are prepared by melting, subsequent ball milling (BM), and followed by spark plasma sintering (SPS). The effects of BM time on the microstructures and thermoelectric properties of these samples are investigated. It is found that BM effectively reduces the grain size to about 90 nm in the sample after SPS, which leads to a decrease in both the thermal conductivity and electrical conductivity. By prolonging the BM time, MnSi and tungsten/carbon-rich impurity phases are formed due to the impact-induced decomposition of HMS and contamination from the tungsten carbide jar and balls during the BM, respectively. These impurities result in a reduced Seebeck coefficient and increased thermal conductivity above room temperature. The measured size-dependent lattice thermal conductivities agree qualitatively with the reported calculation results based on a combined phonon and diffuson model. The size effects are found to be increasingly significant as temperature decreases. Because of the formation of the impurity phases and a relatively large grain size, the ZT values are not improved in the ball-milled HMS samples. These findings suggest the need of alternative approaches for the synthesis of pure HMS with further reduced grain size and controlled impurity doping in order to enhance the thermoelectric figure-of-merit of HMS via nanostructuring.

    ABSTRACT: Quantitative microstructure information is critical to modeling and prediction of mechanical properties of structural components. In this study, the microstructure characteristics of aged squeeze-cast AZ91 alloy were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM) analyses. Particularly, a study of the three-dimensional morphology of continuous precipitation during heat treatment was carried out using a combination of TEM and AFM. The results showed that a typical precipitate consisted of three kinds of faces, namely, broad, side, and end faces. The precipitate also presented a lath-shaped morphology with lozenge ends. Combined SEM and TEM analyses revealed quantitative information on the sizes and area number densities of precipitates after aging at different temperatures with different times. In general, the length and width of precipitates increased more rapidly than thickness during aging. The area number density initially increased and then slowly decreased because of coarsening. Furthermore, a special microstructure characteristic of the non-uniform continuous precipitation during aging was investigated using electron probe microanalysis (EPMA). The relationship between hardness response and yield strength was established.

    ABSTRACT: Bi3.25La0.75Ti3O12 (BLT) ferroelectric thin films were prepared on Pt/Ti/SiO2/Si substrates by metalorganic decomposition method. Mechanical stress effect on leakage current was investigated. The results demonstrate that the leakage current increases with increasing electric field. Under mechanical tensile or compressive stress, the increase trend of the leakage current with electric field shows negligible change in low field region (below 75 kV/cm), while that gets weakened in high field region (above 75 kV/cm) compared with that at free state (zero stress). At a certain electric field (above 75 kV/cm), the leakage current decreases with increasing tensile or compressive stress. The effect of domain reorientation induced by stress combined with the contribution from charge injected into films is found to be reasonable for the explanation of the leakage current in BLT thin films under different stress.

    ABSTRACT: The effect of a steady magnetic field on reactive diffusion in Ni–Al diffusion couples was investigated. The diffusion couples prepared by the electrodeposition technique were annealed in the temperature range of 530–590 °C with and without the magnetic field of 6 T. Regardless of the magnetic field, two intermetallic compounds, i.e., Ni2Al3 and NiAl3, were present in the product layers of diffusion couples. NiAl3 phase shows island-like structures at relatively lower temperatures while the Ni2Al3 phase forms a typical layered structure. The growth of Ni2Al3 layer was found to be parabolic. When the diffusion direction was perpendicular to the direction of the magnetic field, the external magnetic field reduced the growth rate of the Ni2Al3 phase. Whereas the magnetic field had no obvious effect on the growth rate of Ni2Al3 layers in the diffusion configuration of mutually parallel directions. The magnetic field intensity and direction dependence of growth rate of Ni2Al3 intermetallic layers can be attributed to the change in number of collision of an atom with neighbors during diffusion due to spiral motion under the action of the Lorentz force, which leads to change the frequency factor, not activation energy, for layer growth.

    ABSTRACT: Two-dimensional transition metal chalcogenides are attracting increasing attention in energy storage due to their unique structures and electronic properties. CuS has been demonstrated with a metal-like electronic conductivity and a high theoretical capacity. In this work, a facile strategy was reported for one-step synthesis of acetylene black (AB) incorporated layered CuS nanosheet via a simple solvothermal route. X-ray diffraction, Raman spectroscopy, scanning electron microscopy and transmission electron microscopy were used to investigate the morphologies and microstructures of the as-prepared materials. Electrochemical data showed that the CuS/AB composites displayed a high specific capacitance of 2981 F/g at 1.0 A/g and retained 64.6% (1924.5 F/g) at a high current density of 20 A/g, indicative of good rate capability. Furthermore, the composites retained approximately 92% of the initial specific capacitance after 600 cycles at a current density of 1.0 A/g, demonstrating good cycling stability. The outstanding electrochemical properties of the CuS/AB composite suggested that it had great potential for practical applications in high-performance supercapacitors and the present synthesis strategy maybe readily extended to the preparation of other composites based on CuS for potential applications in energy storage and conversion devices.

    ABSTRACT: Translucent alumina ceramics with high transparency were successfully prepared via gelcasting and vacuum sintering. Effects of powder properties and copolymer content on solids loading of the slurry and then on the porosity, microstructures of both green bodies and sintered ceramics, as well as optical transmittance of the final ceramics were extensively investigated. Fine and de-agglomerated alumina powder was effective to prepare slurries with higher solids loading. They resulted in lower porosity (higher relative density) and smaller pore size in green bodies. After sintered at 1860 °C for 6 h in vacuum, the resultant ceramics from higher solids loading had less residual pores. In-line transmittance of the ceramic (1 mm thick) from 55 vol% solids loading reached as high as 53.6% at 600 nm, much higher than previously reported data (<30%).

    ABSTRACT: Tetragonal-structured Mg2YVO6 ceramics were prepared by conventional solid-state method, and their physical and microwave dielectric properties were investigated for the first time. The forming of Mg2YVO6 main phase was confirmed by XRD diffraction pattern. XPS and Raman spectrum were recorded to clarify the chemical states of elements and vibration and rotation modes of the specimen, respectively. In addition, the relationships between sintering temperature, packing fraction, and microwave dielectric properties in Mg2YVO6 ceramics were also studied. The new microwave dielectric material Mg2YVO6 ceramics sintered at 1290 °C for 4 h has a dielectric constant (εr) of ∼10.88, a Q × f of ∼68,300 GHz (f = 10.389 GHz), and a τf ∼ −53.9 ppm/°C, demonstrating a candidate for microwave application.

    ABSTRACT: A transparent nickel selenide (Ni0.85Se) is prepared by a facile solvothermal reaction and used as an efficient Pt-free counter electrode (CE) for dye-sensitized solar cells (DSSCs). Field emission scanning electron microscopy observes that the as-prepared Ni0.85Se possesses porous structure. Cyclic voltammogram measurement indicates that Ni0.85Se electrode has larger current density than Pt electrode. Electrochemical impedance spectroscopy shows that the Ni0.85Se electrode has lower charge-transfer resistance than Pt electrode. Under simulated solar light irradiation with intensity of 100 mW cm−2 (AM 1.5), the DSSC based on the Ni0.85Se CE achieves a power conversion efficiency (PCE) of 8.88%, which is higher than the solar cell based on Pt CE (8.13%). Based on the transparency of Ni0.85Se, the DSSC with Ni0.85Se/mirror achieves a PCE of 10.19%.

    ABSTRACT: The aluminum foam sandwich (AFS) with metallic bonding was fabricated by means of fluxless soldering with self-abrasion. The effects of abrasion forms on interfacial feature, the deformation and failure behavior of AFS are compared through microstructural observation and static three-point bending tests. The good wetting process was realized assisting with the abrasion. The self-abrasion of aluminum foam produced mechanical stirring to make the microstructure more uniform and reduce the defects of the soldering seam. The load–deflection curve of AFS with metallic bonding exhibited three distinct regions. Three failure modes with indentation, core shear and plastic hinge were identified during the bending tests. An excellent bonding has been informed between aluminum alloy face sheets and aluminum foam core due to the retained cohesion between them. Assisting with self-abrasion, fluxless soldering using a zinc-based alloy has been proven to be suitable for fabricating AFS.
