  • Influence of Silver Nanoferrite and Nanochromite on Physical Properties
           for High-Frequency and Biomedical Applications

    • Free pre-print version: Loading...

      Abstract: In this work, the effects of silver nanoferrite and nanochromite (Ag2Fe2O2, Ag2Cr2O4) were studied using the flash auto-combustion technique. Numerous physical properties were clarified from the different structures determined from the x-ray examination such as lattice parameter the cation dispersion, oxygen parameter, hopping length, and interatomic distance. Among antimicrobial properties, Ag addition to both samples showed high efficacy against both types of tested bacteria (gram-positive and gram-negative); however, they showed moderate effect against Candida albicans fungus. No activity appeared against Aspergillus flavus fungus for both samples. The switching field and high-frequency response of Ag2Fe2O4 and Ag2Cr2O4 nanoparticles were studied from the magnetic properties. Ag2Cr2O4 nanoparticles are expected to be used for high-frequency applications more than Ag2Fe2O4 ones. As a result of all previous analyses, the applications of this study promote the use of Ag2Fe2O4 nanoferrite and Ag2Cr2O4 nanochromite for high-frequency, switching field, and biomedical applications as antimicrobial nanomaterials.

  • Simulation Study of the Microstructure and Defects During the Directional
           Solidification of GaAs

    • Free pre-print version: Loading...

      Abstract: The preparation of high-quality GaAs crystals is the basis for the development of high-frequency microwave electronic devices and light-emitting devices. A molecular dynamics (MD) simulation of the directional solidification of GaAs was conducted. The anisotropic growth process and structural defects have been analyzed by radial distribution function, the largest standard cluster analysis, and visualization analysis. The results indicate that induced crystallization with different crystal orientations leads to different microstructural changes, which in turn cause the anisotropic growth of GaAs crystals. During the [100] crystal-oriented solidification, only sphalerite crystal structures were present in the system, while wurtzite structures were also formed in the [110] and [111] crystal orientation systems, and the [111] crystal orientation system is the more obvious. In addition, due to the dense packing structure of the (111) plane, numerous partial dislocations with a Burgers vector of 1/6< 112 > are formed in the GaAs crystal, and there is also a companion relationship between such dislocations and twins, which significantly reduces the crystallization effect. The study of the microstructure evolution of GaAs on the atomic scale provides a reference for the theory of crystal growth.

  • A Comparative Study on Corrosion Behaviors of 15CrMo in Saline (Na2SO4)
           Gas Phase and Liquid Phase at 350°C

    • Free pre-print version: Loading...

      Abstract: The differences between the corrosion behaviors of 15CrMo in saline (Na2SO4) saturated steam and saline saturated water are clarified in this study. The corroded samples were analyzed by scanning electron microscope/energy dispersive spectrum (SEM/EDS), x-ray diffraction, and x-ray photoelectron spectroscopy. The results indicate that the destruction of cementite (Fe3C) could be intensified in the saline gas phase. In saline saturated steam (gas phase), the corroded surface is mainly covered by Fe3O4, which is in form of irregular particles. In addition,, dissolved SO in the steam (gas phase) is reduced to S2–. In the gas-phase corrosion of 15CrMo, insoluble sulfide occurs. In saturated saline water (liquid phase), smaller particles are distributed on the surface. The corrosion products in liquid-phase corrosion consists of Fe3O4, Fe2O3, and Fe. The surface of 15CrMo in the saturated saline gas phase is corroded more severely than in the liquid phase in the fixed conditions. The crystal Fe3O4 is well formed in the liquid/gas phases. The crystallinities of Fe3O4 are 99.50% (gas-phase corrosion) and 99.87% (liquid-phase corrosion).

  • Model Experiment for Molten Metal Temperature Homogenization with Rotating
           Permanent Magnet

    • Free pre-print version: Loading...

      Abstract: In order to obtain a uniform thermal distribution of a liquid metal melt in e.g. aluminum furnaces, mixing can be provided by rotating permanent magnets. A rotating permanent magnet generates a rotating magnetic field which induces a volume force in the nearby liquid metal. This paper presents a quick-and-dirty experimental and numerical study of temperature equalization with a permanent magnet for a liquid metal volume with a vertical temperature gradient. Thermocouples and a thermal camera have been used to capture the temperature dynamics. The setup consists of a thin walled stainless steel container filled with GaInSn eutectic alloy and a cylindrical NdFeB permanent magnet placed near the side wall. A parametric sweep has been performed by changing the inclination angle of the magnet in order to find the most efficient position for which the thermal balance can be achieved the fastest.

  • Field-Dependent Magnetic Domain Behavior in van der Waals Fe3GeTe2

    • Free pre-print version: Loading...

      Abstract: Two-dimensional magnetic van der Waals (vdW) materials can show a variety of topological nontrivial spin textures, such as Bloch- or Néel-type stripe, skyrmion, or bubble domains under certain external stimuli. It is critical to understand the magnetic domain behavior in vdW materials in order to control their size and density in response to external stimuli, such as electric and magnetic fields. We examine the magnetic field dependence of topologically non-trivial magnetization spin textures in vdW Fe3GeTe2. Néel-type stripe domains and skyrmions are formed depending on the magnetic field-cooling protocol used during in situ Lorentz transmission electron microscopy (LTEM) experiments. Use of quantitative reconstruction of magnetic induction maps and micromagnetic simulations allow for the understanding of the LTEM results of Néel-type stripe domains as well as skyrmions. In addition, the deformation of skyrmion contrast is observed as a result of the introduction of an in-plane magnetic field. We demonstrate the stability of the stripe domains and skyrmions in response to an externally applied magnetic field due to an energy barrier for domain wall annihilation. Our results establish an understanding of the energy landscape that governs the behavior of the topologically non-trivial spin textures in vdW materials which can be harnessed for spintronic applications.

  • Reaction Products from High Temperature Treatments of (LaxGd1−x)2Zr2O7
           System and Volcanic Ash Powder Mixtures

    • Free pre-print version: Loading...

      Abstract: Abstract Rare-earth zirconate (REZ) pyrochlores, specifically (La,Gd)2Zr2O7, are promising alternatives to substitute 7YSZ in thermal barrier coatings (TBC) due to their increased phase stability and resistance to calcium-magnesium-aluminosilicate (CMAS)-based damage at high temperatures. This work analyses the reaction products of isothermal treatments at 1250°C of (LaxGd1−x)2Zr2O7 powder mixtures in reaction with natural volcanic ashes (VAs) with different chemical compositions (Popocatepetl, Colima, and Eyjafjallajökull). The chemical composition in the (LaxGd1−x)2Zr2O7 system showed a strong influence on the formation of reprecipitation products (Zr,Gd,La oxides), reactive crystallization products (La-Gd apatites, lanthanum silicates, zirconolite, and garnets), and intrinsic crystallization products (hematite-like structures). The formation of garnets, which enhances the mitigation effect against molten VAs/Si deposit damage, was observed more promptly on (La0.5Gd0.5)2Zr2O7 promoted by high contents of Fe, Ca, Ti, and Mg on VAs. Thus, the (La0.5Gd0.5)2Zr2O7 system stands as a possible candidate to overcome today’s threats for the integrity of current TBCs.

  • Machine Learning Interatomic Potential for High-Throughput Screening of
           High-Entropy Alloys

    • Free pre-print version: Loading...

      Abstract: Abstract We have developed a machine learning-based interatomic potential (MLIP) for the quaternary MoNbTaW (R4) and quinary MoNbTaTiW (R5) high-entropy alloys (HEAs). The MLIP enabled accurate high-throughput calculations of the elastic and mechanical properties of various non-equimolar R4 and R5 alloys, which are otherwise very time-consuming calculations when performed using density functional theory (DFT). We demonstrate that the MLIP predicted properties compare well with the DFT results on various test cases, and are consistent with the available experimental data. MLIPs are also utilized for high-throughput screening of non-equimolar R4 candidates by guided iterative tuning of R4 compositions, to discover candidate materials with promising hardness–ductility combinations. We also used this approach to study the effect of Ti concentration on the elastic and mechanical properties of R4, by statistically averaging the properties of over 100 random structures. The MLIPs predicted the hardness and bulk modulus of equimolar R4 and R5 HEAs which were validated using experimentally measured Vicker’s hardness and modulus. This approach opens a new avenue for employing MLIPs for screening HEA candidates.

  • Static Recrystallization Behavior of Mg–Gd–Y–Zn–Zr Alloy During
           Annealing Treatment

    • Free pre-print version: Loading...

      Abstract: Abstract The static recrystallization (SRX) behavior of upsetting-extrusion (UE) deformed Mg-13.14Gd-3.86Y-2.0Zn-0.39Zr alloy after different annealing treatments was investigated. The results shown that the SRX occurs after annealing treatment. The degree of SRX increased with increasing annealing temperature. Inside the deformed grains, the main formation mechanism of the recrystallized grains was due to the gradual transformation of a large number of low-angle grain boundaries (LAGBs) into high-angle grain boundaries (HAGBs) with the annealing treatment, thereby forming new grains. At the same time, the dislocation density of the alloy was also reduced. The average grain size decreased because the coarse deformed grains were gradually eroded by new recrystallized grains. No phase transformation occurred in the alloy after annealing treatment. The finely dispersed Mg5(Gd,Y) phase transformed from being abundantly distributed at the grain boundaries of the dynamic recrystallization (DRX) grains to precipitate gradually at the recrystallized grain boundary and inside the grains. The annealing treatment consumed the lamellar and block-shaped long-period stacking ordered (LPSO) phases as strengthening phases, and the newly generated recrystallized grains had random orientations, so the basal texture strength of the alloy decreased.

  • Combined Experimental and Computational Study of Molybdenum and Niobium
           for Nuclear Sensor Application

    • Free pre-print version: Loading...

      Abstract: Abstract Due to their novel electromagnetic and thermal properties, molybdenum (Mo) and niobium (Nb) become optimal temperature sensor materials for nuclear energy applications. We leveraged voltage recorded during a heat ramp to tune a computational method to predict the Seebeck electromotive force (EMF) of Mo and Nb. Using a combined Density Functional Theory (DFT) and Boltzmann Transport Equations (BTE) method the voltage was predicted but did not include the effects of temperature on atomic structure. Combining Ab Initio Molecular Dynamics (AIMD) and BTE included temperature effects on structure optimization and yielded voltages in a good agreement with experiment. Lanthanum (La) and Phosphorus (P) additives in Mo and Nb, respectively, could increase the EMF compared to those of the pure metals. The presence of oxygen (O) in Mo increases the EMF while O in Nb slightly reduces the EMF. Our studies suggested that heat treatment-induced structural changes that lead to a reduction in voltage occur not only at the mesoscale as previously understood but also at the atomic scale.
