Aluminum metal matrix composites are valued for their lightweight nature, high performance, and favorable thermal expansion characteristics, preparing them to be suitable for aerospace, defense, automotive, athletic training equipment, and electronics applications. Al-7175 alloy, widely employed in aerospace for advancing structural components, is selected in this pilot study as a base material. reinforcements included varying weight percentages of Al2O3 (2, 4, 6, and 8%), SiC (three levels), and palm kernel shell ash (PKSA) as a sustainable waste-based additive. The composite are fabricated by stir casting method, and test specimens are prepared in accordance with international standards to evaluate stiffness, tensile strength, impact resistance, and wear behavior. The results revealed that incorporating Al₂O₃, SiC, and PKSA enhanced stiffnesses per the additives added in MMCsby1%, 1.5%, 1.6%, and 1.7% (as per the wt.%) and tensile strengthby8%, 10%, and 40, impact resistance by7%, 34%, 25%, and 42%, reduced wear by 2.4%, 22%, and 7.2%due to the synergistic effect of these reinforcements. An L9 orthogonal array and design of experiments (DOE) approach are employed to optimize Wire Electrical Discharge Machining (WEDM) parameters, for minimal surface roughness and optimal material removal rate (MRR). MRR reduction is linked to a higher Ton, voltage, wire feed rate, and Toff settings, with long-range producing higher MRR at minimum reinforcements level but increases in surface roughness. Optimal WEDM parameters are determined as Ton = 5, Toff = 5, voltage = 75, and wire feed = 6, enabling efficient and precise production ofAl-7175 hybrid metal matrix composites (HMMCs) reinforced with Al2O3, SiC, and PKSA across different weight fractions.
Herein, using first-principle calculations and full potential linearized augmented plane wave, the structural, mechanical, and opto-electronic properties of K3XO (X = Cl, Br, and I) anti-perovskite oxides have been studied under different pressures. The structures optimization shows cell parameters very close to the available experimental and theoretical values. The mechanical stability criteria is checked by computed the elastic constants C11, C12 and C44 using the optimized data. Our results also demonstrate the ductility of the all compounds under study and their usefulness in medium-temperature devices, as they have a relatively high Debye temperature. Furthermore, the calculated band structure revealed a direct band gap for the three antiperovskites, the energy band gap values are about 4.21, 3.55 and 3.16 eV for K3ClO, K3BrO and K3IO, respectively, these values of Eg increase linearly as a function of pressure. We investigate also the optical properties of these compounds under various pressures, such as the dielectric function, absorption coefficient, energy loss function, reflectivity and refractive index, within the photon energy interval 0-25 eV, hence all the studied antiperovskites exhibit excellent optical properties, including low reflectivity and high absorption in the ultraviolet region which is good for photovoltaic applications.
Deep-sea mud is expected to be a novel and potential rare earths resource that supplements terrestrial rare earths, and has received international attention. In this work, the leaching kinetics and behavior of rare earths from deep-sea mud with sulfuric acid was investigated. The results revealed that the rare earth elements (REEs) could be leached out via a sulfuric acid leaching process. A optimized REEs leaching percentage of 82.83% was obtained by using 1.0 mol/L sulfuric acid as leaching agents with a liquid-solid ratio of 4:1 and stirring speed of 250 rpm at 60℃ for 30 min. Under the optimized leaching conditions, the leaching kinetics analysis showed that the leaching process was conformed to the shrinking-core model which contained two stages as follows: 1) From 0 min to 4 min, the reaction was controlled through an external diffusion process, and could be described as X = 0.5491·e–4569/RT·t (Ea = 4.569 kJ/mol); 2) From 4 min to 30 min, due to the increase of solid calcium sulfate products, the reaction gradually transformed into an internal diffusion-controlled process, and could be described as 1 – 2/3X – (1 – X)2/3 = 0.0577·e–7083/RT·t (Ea = 7.083 kJ/mol).
This study introduces a dual-objective optimization framework for the laser powder bed fusion (PBF-LB) of TC11 titanium alloy, designed to concurrently mitigate deformation and improve densification. A multiphysics finite element model, which incorporates temperature-dependent material properties, was developed to investigate the deformation mechanisms across an energy density range of 21.2-54.5 J/mm3. Experimental validation, conducted using 3D laser scanning, demonstrated close alignment with the predicted outcomes, with maximum deviations ranging from 0.04 to 0.08 mm. Systematic density measurements uncovered the nonlinear coupling effects between laser power and scan speed, resulting in an empirical power-velocity equation (P = 0.2V + 30, where P denotes laser power and V represents scanning speed), which yielded a peak relative density of 99.2%. The proposed strategy offers a comprehensive approach to the precision manufacturing of complex PBF-LB components, effectively balancing dimensional accuracy with mechanical performance, while minimizing experimental effort.
In this study, super-paramagnetic Zn0.8Ni0.2Fe2O4 ferrite nanoparticles were synthesized simultaneously with the PEG layers covering using the hydrothermal method. The X-ray Diffraction (XRD) was used to determine the structure of ferrite, the Scanning Electron Microscope (SEM) indicated that the average size of particles was approximately 10.7-13.1 nm, respectively, and PEG affected to change the average size of the particle, besides, they can be a good candidate for the agglomeration of the particles, this lead to keep the super-paramagnetic state of them. Additionally, the Vibrating Samples Magnetometer (VSM) revealed that the magnetization saturation Ms of samples reached the highest value (28.47 emu/gr) with 0.15 g/5 ml PEG concentration. The high saturation magnetization of super-paramagnetic Zn0.8Ni0.2Fe2O4 ferrite nanoparticles promises a good ability for applications such as microwave absorbing materials, X-ray clothing protection, MRI contrast image enhancement, target drug delivery, and gas sensors.
This study investigates the effects of solution and aging heat treatments on SiCp/Al-Mg-Si-Cu aluminum matrix composites using scanning electron microscopy, confocal microscopy, salt spray corrosion tests, and electrochemical characterization. Solution and aging treatments promote finely dispersed CuMgA2 phases, significantly enhancing mechanical properties, increasing hardness to 134 HV and strength to 440 MPa. With prolonged corrosion, particle stripping on the composite surface intensifies. After 8 days of corrosion, morphology fluctuation variances are 14.40 for untreated samples, 5.73 for solution-treated samples, and 4.40 for aged samples. Electrochemical tests reveal that aged samples have the lowest corrosion current (1.616×10–7 A/cm2) and the largest capacitive arc, indicating superior corrosion resistance. XPS analysis confirms that aging results in uniformly distributed CuMgAl2 phases, enhancing corrosion resistance. Aging treatment significantly improves corrosion resistance, followed by solution treatment, with untreated samples performing the worst.
The oxidization roasting process is an effective method for synthetizing micron-sized spherical manganese ferrite (MnFe2O4) with a multilayer structure. In the synthesis process of the manganese ferrite samples, the phase formation, morphology evolution and interfacial reactions of the MnO-Fe2O3 system under different factors were comparatively investigated. The experimental results revealed that manganese ferrite with a magnetization saturation (Ms) value of 64.96 emu/g and a coercivity (Hc) value of 34.10 Oe can be successfully synthesized for 30 min at 1300°C with a Mn/Fe molar ratio of 1:2 in an air atmosphere. However, the micron-sized spherical manganese ferrite samples exhibited a total pore volume of 0.034 cm3/g, a pore volume of 0.032 cm3/g, a specific surface area (SSA) of 6.41 cm3/g and an average particle size (APS) of 20.96 nm. The reduction roasting conditions facilitated the formation of micron-sized spherical MnFe2O4, with FexMn1-xO (0 ≤ y ≤ 1) as intermediates. These intermediates were subsequently oxidized to MnxFe3-xO4 (1 < x ≤ 3), MnxFe3-xO4 (0 < x < 1), and MnFe2O4 under different stages and conditions. Additionally, tetrahedral coordinated Mn²⁺ ions in Mn3O4 with spinel-type crystal structures were replaced by tetrahedral coordinated Fe²⁺ ions to form MnxFe3-xO4 with a similar crystal structure. Both normal and inverse spinel structures of manganese ferrite coexist and transform during the synthesis of MnxFe3-xO4 via the oxidization roasting process.
Against the backdrop of dwindling energy supplies and escalating environmental pressures in ironmaking, low-carbon ironmaking technologies have garnered significant research attention. This study centers on developing blast furnace biomass composite pellets from carbon-neutral biomass and high-silica magnetite concentrate. The physicochemical properties and pyrolysis behaviors of these biomass materials are systematically analyzed. From a microscopic structural perspective, the feasibility of forming spherical biomass composite pellets is critically discussed, followed by an in-depth examination of their strength and phase structure evolution. When the biomass addition ratio reaches 7%, the compressive strength of rice husk-waste wood chip composite pellets exceed 2200.00 N·P–1, while waste wood chip-based composite pellets exhibit a higher strength of 2660.03 N·P–1. High-temperature roasting of high-silica ore generates bridging solid solutions and minor complex silicates, which are dispersed within pores and between particles. This phenomenon enhances the structural integrity of composite pellets and reinforces their compressive strength. This work establishes a theoretical foundation for producing high-quality biomass composite pellets in blast furnace operations.
