445-485页

查看更多>>摘要：Within the past ten years,spark plasma sintering(SPS)has become an increasingly popular process for Mg manufacturing.In the SPS process,interparticle diffusion of compressed particles is rapidly achieved due to the concept of Joule heating.Compared to traditional and addi-tive manufacturing(AM)techniques,SPS gives unique control of the structural and microstructural features of Mg components.By doing so,their mechanical,tribological,and corrosion properties can be tailored.Although great advancements in this field have been made,these pieces of knowledge are scattered and have not been contextualized into a single work.The motivation of this work is to address this scientific gap and to provide a groundwork for understanding the basics of SPS manufacturing for Mg.To do so,the existing body of SPS Mg literature was first surveyed,with a focus on their structural formation and degradation mechanisms.It was found that successful Mg SPS fabrication highly depen-ded on the processing temperature,particle size,and particle crystallinity.The addition of metal and ceramic composites also affected their mi-crostructural features due to the Zener pinning effect.In degradative environments,their performance depends on their structural features and whether they have secondary phased composites.In industrial applications,SPS'd Mg was found to have great potential in biomedical,hydrogen storage,battery,automotive,and recycling sectors.The prospects to advance the field include using Mg as a doping agent for crystallite size re-finement and using bulk metallic Mg-based glass powders for amorphous SPS components.Despite these findings,the interactions of multi-composites on the processing-structure-property relationships of SPS Mg is not well understood.In total,this work will provide a useful direc-tion in the SPS field and serve as a milestone for future Mg-based SPS manufacturing.

486-511页

查看更多>>摘要：Metal-air battery is an environmental friendly energy storage system with unique open structure.Magnesium(Mg)and its alloys have been extensively attempted as anodes for air batteries due to high theoretical energy density,low cost,and recyclability.However,the study on Mg-air battery(MAB)is still at the laboratory level currently,mainly owing to the low anodic efficiency caused by the poor corrosion resistance.In or-der to reduce corrosion losses and achieve optimal utilization efficiency of Mg anode,the design strategies are reviewed from microstructure perspectives.Firstly,the corrosion behaviors have been discussed,especially the negative difference effect derived by hydrogen evolution.Spe-cial attention is given to the effect of anode micro-structures on the MAB,which includes grain size,grain orientation,second phases,crystal structure,twins,and dislocations.For further improvement,the discharge performance,long period stacking ordered phase and its enhancing effect are considered.Meanwhile,given the current debates over Mg dendrites,the potential risk,the impact on discharge,and the elimination strategies are discussed.Microstructure control and single crystal would be promising ways for MAB anode.

查看更多>>摘要：Magnesium(Mg)alloys are lightweight materials with excellent mechanical properties,making them attractive for various applications,inclu-ding aerospace,automotive,and biomedical industries.However,the practical application of Mg alloys is limited due to their high susceptibility to corrosion.Plasma electrolytic oxidation(PEO),or micro-arc oxidation(MAO),is a coating method that boosts Mg alloys'corrosion resist-ance.However,despite the benefits of PEO coatings,they can still exhibit certain limitations,such as failing to maintain long-term protection as a result of their inherent porosity.To address these challenges,researchers have suggested the use of inhibitors in combination with PEO coat-ings on Mg alloys.Inhibitors are chemical compounds that can be incorporated into the coating or applied as a post-treatment to further boost the corrosion resistance of the PEO-coated Mg alloys.Corrosion inhibitors,whether organic or inorganic,can act by forming a protective barrier,hindering the corrosion process,or modifying the surface properties to reduce susceptibility to corrosion.Containers can be made of various ma-terials,including polyelectrolyte shells,layered double hydroxides,polymer shells,and mesoporous inorganic materials.Encapsulating corrosion inhibitors in containers fully compatible with the coating matrix and substrate is a promising approach for their incorporation.Laboratory studies of the combination of inhibitors with PEO coatings on Mg alloys have shown promising results,demonstrating significant corrosion mitigation,extending the service life of Mg alloy components in aggressive environments,and providing self-healing properties.In general,this review presents available information on the incorporation of inhibitors with PEO coatings,which can lead to improved performance of Mg alloy com-ponents in demanding environments.

查看更多>>摘要：The paper reports on the atomic investigation about β phase in Mg96Gd2Y1Ni1 alloy by using the first-principles study and the high-angle an-nular dark-field scanning transmission electron microscope(HAADF-STEM)corrected by atomic Cs.By using HAADF-STEM,the rectangularβ phases were observed in the underage and peak aging stages in Mg96Gd2Y1Ni1 alloy.The β phase could be precipitated from the previously precipitated β phase,and the β phase grew in steps when it was precipitated.A special transition structure of three atomic layer thicknesses was first observed at the edge of the β phase and the structure of this interface is probably as the β/Mg1 interface for the analysis of thermodynamic characterization and electronic characterization.The β'phase and the βH structure were precipitated only at the edge of the length directions of the β phase.The β'phase continues to grow into a β phase directly without the formation of β1 phase,resulting in an increase in the length of the β phase,which is discovered for the first time.

查看更多>>摘要：In order to obtain Mg alloys with fine microstructures and high mechanical performances,a novel friction-based processing method,name as"constrained friction processing(CFP)",was investigated.Via CFP,defect-free Mg-Zn-Ca rods with greatly refined grains and high mechanical properties were produced.Compared to the previous as-cast microstructure,the grain size was reduced from more than 1 mm to around 4 pm within 3 s by a single process cycle.The compressive yield strength was increased by 350％while the ultimate compressive strength by 53％.According to the established material flow behaviors by"tracer material",the plastic material was transported by shear deformation.From the base material to the rod,the material experienced three stages,i.e.deformation by the tool,upward flow with additional tilt,followed by upward transportation.The microstructural evolution was revealed by"stop-action"technique.The microstructural development at regions adjacent to the rod is mainly controlled by twinning,dynamic recrystallization(DRX)as well as particle stimulated nucleation,while that within the rod is related to DRX combined with grain growth.

586-602页

查看更多>>摘要：For the sake of improving the mechanical properties and corrosion resistance of biodegradable Mg alloy synergistically,various content of el-ement V(0％,0.05％,0.10％,0.15％,0.20％,in mass fraction)are introduced into an Mg-Zn-Y alloy with long-period stacking ordered(LP-SO)structure,and the effects of V on its microstructure,mechanical properties and corrosion resistance are investigated systematically.The re-sults indicate that the grains are effectively refined by V addition,and the primary α-Mg in Mg-Zn-Y-V0.1 alloy is most significantly refined,with grain size being decreased by 62％.The amount of 18R LPSO structure is increased owing to the V addition.The growth mode of the sec-ond phase(W-phase and 18R LPSO structure)is transformed to divorced growth pattern,which ascribes to the thermodynamic drive force of V to promote the nucleation of LPSO phase.Thus,18R LPSO structure presents a continuous distribution.Due to grains refinement and modifica-tion of second phase,the tensile strength and strain of alloys are both enhanced effectively.Especially,the ultimate tensile strength and the elon-gation of V0.1 alloy are 254 MPa and 15 26％,which are 41％and 61％higher than those of V-free alloy,respectively.Owing to the continu-ously distributed 18R LPSO structure with refined grains and stable product film,the weight loss and hydrogen evolution corrosion rates of V0.1 alloy are 7.1 mm·a-1 and 6.2 mm·a-1,respectively,which are 42.6％and 45.4％lower than those of V-free alloy.

查看更多>>摘要：Magnesium(Mg)-based bone implants degrade rapidly in the physiological environment of the human body which affects their structural in-tegrity and biocompatibility before adequate bone repair.Rare earth elements(REEs)have demonstrated their effectiveness in tailoring the corro-sion and mechanical behavior of Mg alloys.This study methodically investigated the impacts of scandium(Sc)and terbium(Tb)in tailoring the corrosion resistance,mechanical properties,and biocompatibility of Mg-0.5Zn-0.35Zr-0.15Mn(MZZM)alloys fabricated via casting and hot ex-trusion.Results indicate that addition of Sc and Tb improved the strength of MZZM alloys via grain size reduction and solid solution strengthe-ning mechanisms.The extruded MZZM-(1-2)Sc-(1-2)Tb(mass fraction)alloys exhibit compressive strengths within the range of 336-405 MPa,surpassing the minimum required strength of 200 MPa for bone implants by a significant margin.Potentiodynamic polarization tests re-vealed low corrosion rates of as-cast MZZM(0.25 mm·a-1),MZZM-2Tb(0.45 mm·a-1),MZZM-1Sc-1Tb(0.18 mm·a-1),and MZZM-1Sc-2Tb(0.64 mm·a-1),and extruded MZZM(0.17 mm·a-1),MZZM-1Sc(0.15 mm·a-1),MZZM-2Sc(0.45 mm·a-1),MZZM-1Tb(0.17 mm ·a-1),MZZM-2Tb(0.10 mm·a-1),MZZM-1Sc-1Tb(0.14 mm·a-1),MZZM-1Sc-2Tb(0.40 mm·a-1),and MZZM-2Sc-2Tb(0.51 mm· a-1)alloys,which were found lower compared to corrosion rate of high-purity Mg(about 1.0 mm·a-1)reported in the literature.Furthermore,addition of Sc,or Tb,or Sc and Tb to MZZM alloys did not adversely affect the viability of SaOS2 cells,but enhanced their initial cell attach-ment,proliferation,and spreading shown via polygonal shapes and filipodia.This study emphasizes the benefits of incorporating Sc and Tb ele-ments in MZZM alloys,as they effectively enhance corrosion resistance,mechanical properties,and biocompatibility simultaneously.

查看更多>>摘要：The self-assembly of hybrid inorganic-organic materials on stationary platforms plays a critical role in improving their structural stability and wide usability.In this work,a novel two-step hydrothermal approach is proposed for synthesizing stable and advanced hybrid coatings on metal-oxide platforms through the surface modification of layered double hydroxide(LDH)films using novel metal-organic frameworks(MOFs).Ini-tially,Mg-Al LDH nanocontainers,grown on a magnesium oxide layer produced through plasma electrolytic oxidation(PEO)of AZ31 Mg alloy substrate,were intercalated with cobalt via an oxidation route,providing the metallic coordination center for the MOF formation.In the subse-quent step,a pioneering technique is introduced,utilizing tryptophan as the organic linker for the first time at a pH of 10.The self-assembly of cobalt-tryptophan complex,driven by the strong bonding between electrophilic sites of monomers and nucleophilic sites,facilitated the formation of a MOF network having a cloud-like structure on the surface of MgAl LDH's film.The resulting MOF-LDH encapsulation containers demon-strate exceptional electrochemical stability when exposed to a 3.5％NaCl solution,surpassing the performance of PEO and pure LDH coatings.This enhanced stability is attributed to the development of a dense top layer and a stable composition within the self-assembled MOF,effectively sealing flaws and preventing the infiltration of corrosive ions into the underlying metallic substrate.The formation mechanism of MOFs on LDH galleries is investigated using density functional theory calculations.
