发布时间：2023-12-18 - 摘要：Influence of magnetic stirring on the solidification structure and segregation behavior of Ti-1023 alloy during VAR steady state melting process was analyzed by SEM （scanning electron microscope）, XRD （X-ray diffraction） and chemical composition analysis. The results reveal that equiaxed grain zone mainly contains acicular and lamellar α structure, while columnar grain zone is mainly composed of equiaxed grain α structure. Fe element content is gradually increased in both equiaxed and columnar grains along the grain growth direction, and the segregation rate of Fe element is more serious in equiaxed grain than that in columnar grain. The segregation rate of Fe element is decreased in both equiaxed and columnar grains with magnetic stirring, and macro-segregation of Fe element in the ingot is decreased, which is closely related to the formation of β phase in the alloy.关键词：VAR;Ti-1023 Alloy;Segregation Behavior;Magnetic Stirring;Solidification Structure

发布时间：2023-12-18 - 摘要：Microstructure evolution and mechanical properties of rolled Mg-4Zn-0.5Er-1Y alloy sheets with annealing at 200380℃ for 0.54 h were investigated. It is found that distinct dynamic recrystallization grain with fine size can be observed in the annealed alloy sheets. Amounts of secondary phase containing RE exist in the matrix alloy, which are broken into fine particle after hot rolling to promote the heterogeneous nucleation of dynamic recrystallization grain. Strength of the alloy sheet after annealing treatment is decreased with the obvious improvement of plasticity. The alloy sheet with approximately 8 μm in size exhibits desirable mechanical properties with annealing at 350℃ for half hour, such as tensile strength of 276MPa and elongation of 22.5%. Activation energy of grain boundary migration reaches 22.76kJ/mol. In addition, kinetics model of dynamic recrystallization grain growth was established.关键词：Heat Treatment;Mechanical Properties;DRX

The results show that, through controlling cooling rate of the alloy, semi-solid AZ91D-3Ca magnesium alloy billets with rosette structure primary phase can be prepared successfully by low voltage pulsed magnetic field. Under low voltage pulsed magnetic field, with increasing in preheating temperature of mould and decreasing in pouring temperature, primary phase dendrites are degraded gradually. Primary phase can be changed from well-developed dendrite to rosette structure under low voltage pulsed magnetic field with only high preheating temperature of the mould or lower pouring temperature.关键词：Low Voltage Pulsed Magnetic Field;Semi-solid;Magnesium Alloy

发布时间：2023-12-18 - 摘要：The interfacial heat transfer coefficient （IHTC） between castings and metal mold during solidification process was calculated through coupling numerical simulation with simulated annealing algorithm based on Isight platform by help of tested temperature data from A356 aluminum alloy. Meanwhile, interface input between the Isight and the ProCAST was resolved successfully. Uniform-step was used to calculate post-treated data, which was more matched with uniform time-step treated experimental data, Furthermore, it was convenient for calculating optimized goal. Through Isight platform integrating with ProCAST software, not only heat transfer coefficient with interface temperature or time can be accurately calculated, but also the method is used to optimize casting process and mould design.关键词：ProCAST Simulation;Isight Optimization;IHTC;Simulated Annealing Algorithm;Inverse

发布时间：2023-12-18 - 摘要：With the aim at replacing the original steel supporter, modal analysis and its structure optimization of die casting magnesium alloy steering supporter were conducted. The results reveal that, compared to that of original steel supporter, the first six normal mode frequency of the magnesium alloy supporter is increased, and the relative vib-displacement is slightly reduced. However, the elastic modulus of magnesium alloy is remarkably lower than that of steel, so the local rigidity of magnesium alloy up-beam is lower than that of steel structure, which results in its first vibration deformation in corresponding to location larger than the original steel structure. Through optimizing the original magnesium alloy structure and improving the local rigidity of the up-beam, modal behavior of the magnesium alloy steering supporter can reach or partly exceed the original steel structure.关键词：Magnesium Alloy;Steering Supporter;Modal Analysis;Structural Rigidity

发布时间：2023-12-18 - 摘要：Impact abrasive wear behavior of thixo-injecting forming hypereutectic high Cr cast iron billets by conventional sand casting and by slope cooling semi-solid casting was analyzed. The results show that slurry fluidity is greatly decreased due to coarse rod-like carbides in conventional as-cast billets, which results in surface rough and internal shrinkage hole in thixo-injecting forming parts, meanwhile, matrix is obviously fragmented by coarse rod-like primary carbides, and the carbides are broken off during wear process, leading to the deterioration of wear resistance. Slurry exhibits acceptable fluidity during thixo-injecting forming process as a result of fine primary carbides in slope cooling semi-solid billets, which leads to smooth surface and low internal defects in the parts, meanwhile, primary carbides and eutectic carbides show fine and uniform, resulting in the low cutting role in matrix and uniformly surface wear, which are responsible for the improvement of wear resistance.关键词：Hypereutectic High Cr Cast Iron;Semi-solid Thixo-injecting Forming;Impact Abrasive Wear Resistance

发布时间：2023-12-18 - 摘要：Effects of deformation temperature and strain rate on deformation behavior of semi-solid 6063 alloy were investigated on the Gleeble 3800 thermal-mechanical simulator at 615630℃ and 0.15s-1. The results show that flow stress of semi-solid aluminum alloy is decreased with increasing in deformation temperature and it is increased with increasing in strain rate. The deformation temperature and strain rate have the significant effects on the peak stress of 6063 alloy rather than steady flow stress. The natural logarithm of the sine equation of alloy flow stress and reciprocal of absolute temperature meets linear relationship, and relationship between flow stress and strain rate meets hyperbolic sine equation. On the basis of the experimental data from semi-solid 6063, a constitutive equation was established by means of the multi-variable regression to describe the relation between the processing parameters and flow stress. The model exhibits desirable precision by comparing calculated results with experimental ones.关键词：6063 Aluminum Alloy;Semi-solid;Thixo-Compression;Constitutive Equation

Semi-solid die casting was conducted. The results reveal that without heating on semi-solid die casting die, liquid aluminum alloy can not completely fill cavity, resulting in occurrence of many casting defects. With heating on mould, castings exhibit desirable formability. In the range of cross-section, with increasing in ingate cross section, quality of the castings is improved.关键词：Aluminum Alloy;Semi-solid;Die Casting Die;Ingate

The results reveal that the lower first shot speed can decrease defects as a result of exhausting air slowly, meanwhile, when the first shot speed reaches 95L/min, defects can be decreased too. In addition, lower pouring temperature and proper injection pressure are beneficial for the decrease of porosities in the die casting bracket.关键词：Aluminum Alloy Bracket;Injecting Speed;Defects;Pouring Temperature

发布时间：2023-12-18 - 摘要：By means of quantitative analysis, critical moving diameter and migration law of the gas bubble in the liquid metal were described theoretically in vertical centrifugal field, and equation of the critical moving diameter and movement velocity on the gas bubble was established and verified through the experiment. The results reveal that in vertical centrifugal field, the critical moving diameter is decreased with increasing in centrifugal angular velocity and radius. Movement velocity of the gas bubble is divided into the rising velocity and the centripetal velocity. With the gas bubble moving, both rising velocity and centripetal velocity are increased with the decrease of acceleration. When the resistance force is equal to the power, the acceleration is zero and the movement velocity reaches maximum value, then it is gradually reduced. The resultant movement velocity of the gas bubble is increased with increasing in the centrifugal angular velocity and radius. The higher the centrifugal angular velocity and radius, the more intensive the migration of gas bubble, so the porosity is more difficult to form. Finally, the experimental result is well in agreement with theoretical analysis.关键词：Centrifugal Casting;Liquid Metal;Gas Bubble;Critical Diameter;Movement Law

The results show that average hardness of particle reinforced Al-20Si-5Mg composites cylinder liner is lower than that of cast iron ones. However, with increasing in loading, under dry sliding condition, wear resistance of the composites cylinder liner at as-cast, solid solution and solid solution +aging state is apparently superior to that of cast iron ones, while under wet condition, with high loading, such as 300N and 400N, it is slightly better than that of cast iron ones.关键词：Particle Reinforced Hypereutectic Al-Si Alloy;Centrifugal Casting;Cylinder Liner;Hardness;Wear Resistance

Microstructure of coating surface was observed by SEM （scanning electron microscope）. The results reveal that, with 1.5A aluminum target current, AlSn20 coating can greatly improve the corrosion resistance of bearing alloy as a result of increasing electrochemical impedance to about 5 to 6 order of magnitude and self-corrosion potential to-1.12V. Corrosion resistance of AlSn20 coating is closely related to aluminum target current. With decreasing in aluminum target current, corrosion resistance of coating is improved increasingly.关键词：Bearing Alloy;AlSn20 Coating;Corrosion Resistance;Self-corrosion Potential

发布时间：2023-12-18 - 摘要：Hydrogen storage alloys La0.83Mg0.1Ni3.25Al0.15Mn0.1 was prepared by induction melting and annealing and by melt spun. Effects of melt spun on the phase structure, microstructure and electrochemical properties of the alloy were investigated by XRD （X-ray diffraction）, EPMA and electrochemical testing. The results reveal that, although effect of cooling rate on phase constituent in the alloy can be neglected, it greatly affected the abundance of different phases. With increasing in cooling rate, abundance of LaNi5 with CaCu5 type structure is increased, while abundance of LaNi3 phase with PuNi3 type structure is decreased. The microstructure of alloy prepared by melt spun is composed of columnar grain structure. In addition, activity of the alloy is almost independent of cooling rate. With increasing in cooling rate, maximum discharge capacity is decreased and cycling stability of the alloy is obviously improved, where S100 reaches 97.03% with cooling rate of 15 m/s.关键词：Melt Spun;La0.83Mg0.1Ni3.25Al0.15Mn0.1 Hydrogen Storage Alloys;Phase Structure;Electrochemical Properties

发布时间：2023-12-18 - 摘要：Effects of different Si, Cu and Mg additions on electrical conductivity and mechanical properties of cast aluminum alloy were investigated by orthogonal testing. The results reveal that Si can improve tensile strength of the aluminum alloy, however, it can also deteriorate the electrical conductivity as a result of severely reducing effective conductive cross-section as a semi-conductor. Cu and Mg can increase the tensile strength of the alloy while they decrease electrical conductivity as a result of Cu and Mg solving in the aluminum matrix resulting in the increase of matrix lattice distortion and scattering rate of electron wave. Electrical conductivity and mechanical properties of the T6 treated alloy are further improved, which is attributed to the homogeneous precipitation of Mg2Si, Al2Cu, CuMgAl2（S） and Q/W （AlxSi4Mg5Cu4） and the weakness of Si dissevering the matrix.关键词：Cast Aluminum Alloy;Alloying Element;Electrical Conductivity;Mechanical Properties

The results reveal that Mn can effectively reduce Fe content in the magnesium melts and improve the current efficiency of magnesium anodes, however, excessive Mn will decrease the current efficiency of the magnesium anodes due to forming a little secondary phase with Si, C, O as the cathode to promote the self-corrosion of the anodes. The matrix microstructure of the Mg-Mn alloy with different Mn contents is composed of α-Mg solid solution phase which exhibits coarse columnar grain with lower Mn content while it becomes equiaxed grain with increasing in Mn content. However, it shows slight change with excessive Mn content.关键词：Mn Content;Mg-Mn Sacrificial Anodes;Microstructure;Electro-Chemical Properties;Fe Content
