    233-255页
    查看更多>>摘要：The rich resources and unique environment of the Moon make it an ideal location for human expansion and the utilization of extraterrestrial resources.Oxygen,crucial for supporting human life on the Moon,can be extracted from lunar regolith,which is highly rich in oxygen and contains polymetallic oxides.This oxygen and metal extraction can be achieved using existing metallurgical tech-niques.Furthermore,the ample reserves of water ice on the Moon offer another means for oxygen production.This paper offers a de-tailed overview of the leading technologies for achieving oxygen production on the Moon,drawing from an analysis of lunar resources and environmental conditions.It delves into the principles,processes,advantages,and drawbacks of water-ice electrolysis,two-step oxy-gen production from lunar regolith,and one-step oxygen production from lunar regolith.The two-step methods involve hydrogen reduc-tion,carbothermal reduction,and hydrometallurgy,while the one-step methods encompass fluorination/chlorination,high-temperature de-composition,molten salt electrolysis,and molten regolith electrolysis(MOE).Following a thorough comparison of raw materials,equip-ment,technology,and economic viability,MOE is identified as the most promising approach for future in-situ oxygen production on the Moon.Considering the corrosion characteristics of molten lunar regolith at high temperatures,along with the Moon's low-gravity envir-onment,the development of inexpensive and stable inert anodes and electrolysis devices that can easily collect oxygen is critical for pro-moting MOE technology on the Moon.This review significantly contributes to our understanding of in-situ oxygen production technolo-gies on the Moon and supports upcoming lunar exploration initiatives.

    256-269页
    查看更多>>摘要：Martensite is an important microstructure in ultrahigh-strength steels,and enhancing the strength of martensitic steels often involves the introduction of precipitated phases within the martensitic matrix.Despite considerable research efforts devoted to this area,a systematic summary of these advancements is lacking.This review focuses on the precipitates prevalent in ultrahigh-strength marten-sitic steel,primarily carbides(e.g.,MC,M2C,and M3C)and intermetallic compounds(e.g.,NiAl,Ni3X,and Fe2Mo).The precipita-tion-strengthening effect of these precipitates on ultrahigh-strength martensitic steel is discussed from the aspects of heat treatment pro-cesses,microstructure of precipitate-strengthened martensite matrix,and mechanical performance.Finally,a perspective on the develop-ment of precipitation-strengthened martensitic steel is presented to contribute to the advancement of ultrahigh-strength martensitic steel.This review highlights significant findings,ongoing challenges,and opportunities in the development of ultrahigh-strength martensitic steel.

    Recent progress in constructing fluorinated solid-electrolyte interphases for stable lithium metal anodes

    Di ZhangPengfei LvWei QinXin He...
    270-291页
    查看更多>>摘要：Lithium metal batteries(LMBs)are emerging as a promising energy storage solution owing to their high energy density and specific capacity.However,the non-uniform plating of lithium and the potential rupture of the solid-electrolyte interphase(SEI)during extended cycling use may result in dendrite growth,which can penetrate the separator and pose significant short-circuit risks.Forming a stable SEI is essential for the long-term operation of the batteries.Fluorine-rich SEI has garnered significant attention for its ability to ef-fectively passivate electrodes,regulate lithium deposition,and inhibit electrolyte corrosion.Understanding the structural components and preparation methods of existing fluorinated SEI is crucial for optimizing lithium metal anode performance.This paper reviews the re-search on optimizing LiF passivation interfaces to protect lithium metal anodes.It focuses on four types of compositions in fluorinated SEI that work synergistically to enhance SEI performance.For instance,combining compounds with LiF can further enhance the mechan-ical strength and ionic conductivity of the SEI.Integrating metals with LiF significantly improves electrochemical performance at the SEI/anode interface,with a necessary focus on reducing electron tunneling risks.Additionally,incorporating polymers with LiF offers balanced improvements in interfacial toughness and ionic conductivity,though maintaining structural stability over long cycles remains a critical area for future research.Although alloys combined with LiF increase surface energy and lithium affinity,challenges such as dend-rite growth and volume expansion persist.In summary,this paper emphasizes the crucial role of interfacial structures in LMBs and offers comprehensive guidance for future design and development efforts in battery technology.

    Effects of aggregate size distribution and carbon nanotubes on the mechanical properties of cemented gangue backfill samples under true triaxial compression

    Qian YinFan WenZhigang TaoHai Pu...
    311-324页
    查看更多>>摘要：The mechanical behavior of cemented gangue backfill materials(CGBMs)is closely related to particle size distribution(PSD)of aggregates and properties of cementitious materials.Consequently,the true triaxial compression tests,CT scanning,SEM,and EDS tests were conducted on cemented gangue backfill samples(CGBSs)with various carbon nanotube concentrations(PCNT)that satisfied fractal theory for the PSD of aggregates.The mechanical properties,energy dissipations,and failure mechanisms of the CGBSs under true triaxial compression were systematically analyzed.The results indicate that appropriate carbon nanotubes(CNTs)effectively enhance the mechanical properties and energy dissipations of CGBSs through micropore filling and microcrack bridging,and the optimal effect ap-pears at PCNT of 0.08wt％.Taking PSD fractal dimension(D)of 2.500 as an example,compared to that of CGBS without CNT,the peak strength(σp),axial peak strain(εl,p),elastic strain energy(Ue),and dissipated energy(Ud)increased by 12.76％,29.60％,19.05％,and 90.39％,respectively.However,excessive CNTs can reduce the mechanical properties of CGBSs due to CNT agglomeration,manifesting a decrease in σp,εl,p,and the volumetric strain increment(Δεv)when PCNT increases from 0.08wt％to 0.12wt％.Moreover,the addition of CNTs improved the integrity of CGBS after macroscopic failure,and crack extension in CGBSs appeared in two modes:detour and pass through the aggregates.Theσp and Ud firstly increase and then decrease with increasing D,and porosity shows the opposite trend.The εl,p and Δεv are negatively correlated with D,and CGBS with D=2.150 has the maximum deformation parameters(εl,p=0.05079,Δsv=0.01990)due to the frictional slip effect caused by coarse aggregates.With increasing D,the failure modes of CGBSs are sequen-tially manifested as oblique shear failure,"Y-shaped"shear failure,and conjugate shear failure.

    Rock fracture mechanism of buffer blasting with cushion layer at the borehole bottom

    325-334页
    查看更多>>摘要：This study primarily investigates the rock fracture mechanism of bottom cushion layer blasting and explores the effects of the bottom cushion layer on rock fragmentation.It involves analyses of the evolution patterns of blasting stress,characteristics of crack distri-bution,and rock fracture features in the specimens.First,blasting model experiments were carried out using the dynamic caustics prin-ciple to investigate the influence of bottom cushion layers and initiation methods on the integrity of the bottom rock mass.The experi-mental results indicate that the combined use of bottom cushion layers and inverse initiation effectively protects the integrity of the bot-tom rock mass.Subsequently,the process of stress wave propagation and dynamic crack propagation in rocks was simulated using the continuum-discontinuum element method(CDEM)and the Landau explosion source model,with varying thicknesses of bottom cushion layers.The numerical simulation results indicate that with increasing cushion thickness,the absorption of energy generated by the explo-sion becomes more pronounced,resulting in fewer cracks in the bottom rock mass.This illustrates the positive role of the cushion layer in protecting the integrity of the bottom rock mass.

    Depression mechanism of sulfite ions on sphalerite and Pb2+activated sphalerite in the flotation separation of galena from sphalerite

    Feng ZhangChenyang ZhangLinlin WuWei Sun...
    335-345页
    查看更多>>摘要：The depression mechanism of sulfite ions on sphalerite and Pb2+activated sphalerite in the flotation separation of galena from sphalerite still lacked in-depth insight.Therefore,the depression mechanism of sulfite ions on sphalerite and Pb2+activated sphalerite in the flotation separation of galena from sphalerite was further systematically investigated with experiments and density functional theory(DFT)calculations.The X-ray photoelectric spectroscopy(XPS)results,DFT calculation results,and frontier molecular orbital analysis indicated that sulfite ions were difficult to be adsorbed on sphalerite surface,suggesting that sulfite ions achieved depression effects on sphalerite through other non-adsorption mechanisms.First,the oxygen content in the surface of sphalerite treated with sulfite ions in-creased,which enhanced the hydrophilicity of the sphalerite and further increased the difference in hydrophilicity between sphalerite and galena.Then,sulfite ions were chelated with lead ions to form PbSO3 in solution.The hydrophilic PbSO3 was more easily adsorbed on sphalerite than galena.The interaction between sulfite ions and lead ions could effectively inhibit the activation of sphalerite.In addition,the UV spectrum showed that after adding sulfite ions,the peak of perxanthate in the sphalerite treated xanthate solution was significantly stronger than that in the galena with xanthate solution,indicating that xanthate interacted more readily with sulfite ions and oxygen mo-lecules within the sphalerite system,leading to the formation of perxanthate.However,sulfite ions hardly depressed the flotation of ga-lena and could promote the flotation of galena to some extent.This study deepened the understanding of the depression mechanism of sulfite ions on sphalerite and Pb2+activated sphalerite.

    346-359页
    查看更多>>摘要：Sinter is the core raw material for blast furnaces.Flue pressure,which is an important state parameter,affects sinter quality.In this paper,flue pressure prediction and optimization were studied based on the shapley additive explanation(SHAP)to predict the flue pressure and take targeted adjustment measures.First,the sintering process data were collected and processed.A flue pressure prediction model was then constructed after comparing different feature selection methods and model algorithms using SHAP+extremely random-ized trees(ET).The prediction accuracy of the model within the error range of±0.25 kPa was 92.63％.SHAP analysis was employed to improve the interpretability of the prediction model.The effects of various sintering operation parameters on flue pressure,the relation-ship between the numerical range of key operation parameters and flue pressure,the effect of operation parameter combinations on flue pressure,and the prediction process of the flue pressure prediction model on a single sample were analyzed.A flue pressure optimization module was also constructed and analyzed when the prediction satisfied the judgment conditions.The operating parameter combination was then pushed.The flue pressure was increased by 5.87％during the verification process,achieving a good optimization effect.

    Effect of Nb-V microalloying on the hot deformation behavior of medium Mn steels

    360-368页
    查看更多>>摘要：The influence of Nb-V microalloying on the hot deformation behavior and microstructures of medium Mn steel(MMS)was investigated by uniaxial hot compression tests.By establishing the constitutive equations for simulating the measured flow curves,we successfully constructed deformation activation energy(Q)maps and processing maps for identifying the region of flow instability.We concluded the following consequences of Nb-V alloying for MMS.(i)The critical strain increases and the increment diminishes with the increasing deformation temperature,suggesting that NbC precipitates more efficiently retard dynamic recrystallization(DRX)in MMS compared with solute Nb.(ii)The deformation activation energy of MMS is significantly increased and even higher than that of some re-ported high Mn steels,suggesting that its ability to retard DRX is greater than that of the high Mn content.(iii)The hot workability of MMS is improved by narrowing the hot processing window for the unstable flow stress,in which fine recrystallized and coarse unrecrys-tallized grains are present.

    Microstructural evolution during the progressive transformation-induced plasticity effect in a Fe-0.1C-5Mn medium manganese steel

    Mei ZhangWenhao LiYangfei ChenYang Jiang...
    369-379页
    查看更多>>摘要：The microstructural evolution of a cold-rolled and intercritical annealed medium-Mn steel(Fe-0.10C-5Mn)was investigated during uniaxial tensile testing.In-situ observations under scanning electron microscopy,transmission electron microscopy,and X-ray dif-fraction analysis were conducted to characterize the progressive transformation-induced plasticity process and associated fracture initi-ation mechanisms.These findings were discussed with the local strain measurements via digital image correlation.The results indicated that Lüders band formation in the steel was limited to 1.5％strain,which was mainly due to the early-stage martensitic phase transforma-tion of a very small amount of the less stable large-sized retained austenite(RA),which led to localized stress concentrations and strain hardening and further retardation of yielding.The small-sized RA exhibited high stability and progressively transformed into martensite and contributed to a stably extended Portevin-Le Chatelier effect.The volume fraction of RA gradually decreased from 26.8％to 8.2％prior to fracture.In the late deformation stage,fracture initiation primarily occurred at the austenite/martensite and ferrite/martensite inter-faces and the ferrite phase.
