    Magneto-plasticity in micro-cutting of single-crystal copper

    查看更多>>摘要：The plasticity of metals can be significantly affected by the application of a magnetic field,otherwise known as the magneto-plastic effect.This paper investigates the magneto-plastic effect in the micro-cutting of a non-magnetic ductile material,single-crystal copper,under a weak magnetic field and re-ports the influence of the phenomenon on the cutting forces and machined surface quality.A softening effect was observed from the large reduction in cutting forces from 3.2 N to 1.5 N under the magnetic field.As compared to the magnetic field intensity and polarity,the variation in magnetic field orien-tations with respect to the cutting direction exhibited a stronger influence on the cutting force,chip morphology,machined surface texture,subsurface microstructure,surface roughness,and machined sur-face microhardness of the copper sample.An analytical model was developed based on the geometry of the cutting chips to correlate the orientation-dependent influence of the magnetic field on the cutting forces.On the surface quality,excessive folds with four different types of morphology produced under magnetic-free cutting were suppressed after applying the magnetic field with the most significant im-provement achieved with the 90° magnetic field direction.The magnetic-assisted changes in machined surface morphology also led to the reduction in machined surface roughness and microhardness.The op-timistic micro-cutting outcomes in this work establish a greater understanding of the magneto-plastic effect and demonstrate the applicability of magneto-plasticity in ultraprecision manufacturing.

    New insights into the mechanism of localised corrosion induced by TiN-containing inclusions in high strength low alloy steel

    查看更多>>摘要：This work investigated the chemical and electrochemical mechanisms of localised corrosion triggered by CaS·xMgO·yAl2O3·TiN complex inclusions in high strength low alloy steel(HSLAS)under a simulated ma-rine environment.Special focus was given to the role of the TiN portion of the inclusion on the initiation and growth of the corrosion pits.The thermodynamic process of pitting initiation was investigated by Gibbs free energy,Pourbaix diagram and first principle calculation.Localised corrosion is mainly induced by inclusions and triggered by dissolution of adjacent distorted matrix.Chemical dissolution of CaS por-tion in CaS·xMgO·yAl2O3·TiN complex inclusion creates an acidic aggressive environment that accelerates the further dissolution of inclusion and matrix.Galvanic coupling effect between TiN inclusion and ma-trix is directly verified.TiN covered with a TiO2 film acts as the cathodic phase in galvanic corrosion,although it has a lower Volta potential than the matrix.This is an unusual correlation with the scanning Kelvin probe force microscopy result,which has been explained for this special system.

    Heterogeneous precipitate microstructure in titanium alloys for simultaneous improvement of strength and ductility

    Mengyuan HaoPei LiXuexiong LiTianlong Zhang...
    150-163页
    查看更多>>摘要：The design of alloys with simultaneous high strength and high ductility is still a difficult challenge.Here,we propose a new approach to designing multi-phase alloys with a synergistic combination of strength and ductility by engineering heterogeneous precipitate microstructures through the activation of differ-ent transformation mechanisms.Using a two-phase titanium alloy as an example,phase field simulations are carried out firstly to design heat treatment schedules that involve both conventional nucleation and growth and non-conventional pseudospinodal decomposition mechanisms,and the calculated microstruc-tures have been evaluated by crystal plasticity finite element modeling.According to simulations,we then set a two-step heat treatment to produce bimodal α+β microstructure in Ti-10V-2Fe-3Al.Further me-chanical testing shows that the ductility of the alloy is increased by～50％and the strength is increased by～10％as compared to its unimodal counterpart.Our work may provide a general way to improve the mechanical properties of alloys through multiscale microstructure design.

    S-scheme CoTiO3/Cd9.51Zn0.49S10 heterostructures for visible-light driven photocatalytic CO2 reduction

    164-170页
    查看更多>>摘要：Cd1-xZnxS solid solutions with strong light absorption are promising materials for solar-driven CO2 re-duction;however,their relatively weak redox ability and intrinsic photo-corrosion limit their further development as a photocatalyst.The addition of a second photocatalyst with a suitable band struc-ture to construct a S-scheme photocatalytic system can solve both problems simultaneously.Here,we report a S-scheme photocatalyst based on the heterostructure of CoTiO3/Cd9.51Zn0.49S10(abbreviated as CoTiO3/CdZnS)that enables the efficient photocatalytic reduction of CO2.Detailed physicochemical char-acterization resolves the S-scheme charge transfer mechanism in this composite photocatalyst.With the well-designed structure of particles and desirable band offsets,this hybrid system offers visible light ab-sorption in a broad spectral region,large surface area,strong redox ability,and fast carrier separation and transportation.Under visible-light illumination,the CoTiO3/CdZnS hybrid system displays a CO formation rate of about 11 mmol h-1 g-1 combined with a long-term operational stability.Besides,a high appar-ent quantum efficiency(AQE)of 7.27％is realized for the CO2-to-CO reduction reaction by the optimized CoTiO3/CdZnS hybrid under 420 nm monochromatic light irradiation.

    Optimizing magnetic/dielectric matching in permalloy/carbonized cotton fiber composites by strain-tunable ferromagnetic resonance and defect-induced dielectric polarization

    Xiaochen ShenChenglong HuWenling RenRongzhi Zhao...
    174-181页
    查看更多>>摘要：Electromagnetic losses in composites could be synergistically controlled by permeability and permittivity,associated with multiple ferromagnetic resonances and dielectric polarization.However,it is still chal-lenging for simultaneous tunability for both the terms in a magnetic/dielectric composite system.Here,we demonstrate the tunable ferromagnetic resonances and the enhanced dielectric losses at gigahertz frequencies in permalloy/carbonized cotton fiber composites with different annealing temperatures.It is theoretically confirmed that the stress field acting on the magnetic permalloy layer increases with increasing temperature because of the shrinkage of the dielectric carbonized cotton fibers,resulting in multiple ferromagnetic resonances,in which there is a linear relationship(fr=1.52 x σ+9.38)be-tween the resonance frequency(fr)and the stress(σ).The present work provides a fundamental insight into understanding the micromagnetic dynamics of the magnetic/dielectric composite system.

    Monodispersed Co@C nanoparticles anchored on reclaimed carbon black toward high-performance electromagnetic wave absorption

    182-192页
    查看更多>>摘要：Recently,developing carbon-based hybrid materials loaded with magnetic components has been gener-ally regarded as a promising and practically feasible strategy when it comes to constructing lightweight electromagnetic wave absorbers.In the current work,reclaimed carbon black(CB)nanopowder was firstly produced by simple burning of wheat straw,which was then employed as sustainable carbon-based host materials(carrier)and successfully decorated Co@C nanoparticles via a simple thermal reduction process.Remarkably,both the as-fabricated nanocomposites and corresponding electromagnetic wave absorption performances could be effectively tuned by tailoring the dosage of the Co@C nanoparticles.The mini-mum reflection loss(RLmin)of-53.989 dB was achieved for CB/Co@C-2#at 2.28 mm thickness,mean-while,CB/Co@C-3#was featured by a wide effective absorption band(EAB)of 6 GHz(6.72-12.72 GHz)at a 2.73 mm matching thickness,which covered the entire X band,suggesting that the CB/Co@C nanocom-posites were an attractive candidate for electromagnetic wave absorber.According to the synergistic influ-ence of dielectric loss and magnetic loss from CB and Co@C,respectively,as well as the properly matched impedance,a reasonable electromagnetic wave attenuation mechanism was illustrated.It is noteworthy that the preparation process of CB is a facile,recycled,and low-cost strategy for achieving nanoscale carbon-based absorbing materials,moreover,the CB/Co@C nanocomposites provide a reference for con-structing lightweight dielectric-magnetic products with superb electromagnetic wave absorption perfor-mances.

    S-scheme ZnO/WO3 heterojunction photocatalyst for efficient H2O2 production

    Zicong JiangBei ChengYong ZhangS.Wageh...
    193-201页
    查看更多>>摘要：Designing highly efficient photocatalyst for hydrogen peroxide(H2O2)production is an ideal strategy to avoid the shortcomings of traditional H2O2 production and to realize the conversion of solar energy to chemical energy.In this work,a step-scheme(S-scheme)heterojunction photocatalyst composed of ZnO and WO3 is carefully prepared by hydrothermal and calcination method for efficient photocatalytic H2O2 production.The ZW30 composite photocatalysts exhibit enhanced activity with the highest H2O2-production rate of 6788 μmol L-1 h-1.The results show that the photocatalytic H2O2 production pro-cess is dominated by a direct two-electron O2 reduction pathway.The enhanced photocatalytic H2O2-production activity is attributed to the formation of interfacial internal electric field(IEF)in the S-scheme heterojunction,which boosts the spatial separation of charge carriers and enables electrons with the strongest reduction power to participate in H2O2 production.This work provides an in-depth insight of the great advantages of S-scheme heterojunction in photocatalytic H2O2 production.
