| 1 | Effects of heat treatment on the microstructure and mechanical properties of ZA84 magnesium alloy显示文摘The effects of heat treatment on the microstructure and mechanical properties of ZA84 (Mg-8Zn-4Al-0.25Mn) alloy were investigated. The results indicate that the as-cast microstructure of the alloy is mainly composed of α-Mg matrix and two different morphologies of precipitates (continuous and quasi-continuous Mg32(Al,Zn)49 phases and isolated Mg5Al2Zn2 phases). After solid solution treatment at 345°C, the Mg32(Al,Zn)49 phases change from continuous and quasi-continuous net to disconnected acute angle shape, and parts of second phases sphericize. The optimum heat treatment condition for the alloy is solution treatment at 345°C for 48 h and water quenching, then aging treatment at 200°C for 12 h and atmosphere cooling. Under the optimum condition, the ulti-mate tensile strength and yield strength of the alloy can be improved, but the elongation is not effected much by heat treatment. | Mingbo Yang Liang Bai Fusheng Pan Hongjun Hu | 2008 | Journal of University of Science and Technology Beijing2008，15，6： | 5 |

| 3 | Selective laser melting of magnesium alloys: Necessity, formability, performance, optimization and applications显示文摘Selective laser melting (SLM), as a rapid prototyping technology, has been widely used to manufacture high-performance metal components with complex structures, which vitally provides a broad platform for the development and application of magnesium alloys. However, the poor laser formability of magnesium alloys has deleterious consequences in the application of SLM processing. This paper discusses the defect formation mechanisms during the SLM process and summarizes characteristics in terms of mechanical properties, oxidation and corrosion resistance. Current optimization schemes are reviewed from both macro and micro perspectives. Firstly, the relationship between process parameters and formability and material properties is clarified, and advanced optimization methods of the design of experiments, physical models, and machine learning are evaluated. Secondly, the effects of alloying elements, composite reinforcement, and post-treatment on the microstructure and properties of the SLMed magnesium alloy are reviewed. Finally, the future application development prospects are envisaged based on the comprehensive review. This work is significantly helpful to a better scientific understanding of SLMed magnesium alloy and puts forward some meaningful guiding opinions for the future work of magnesium alloy manufacturing. | Kun Li Chen Ji Shengwen Bai Bin Jiang Fusheng Pan | 2023 | Journal of Materials Science & Technology2023，，23： | 1 |

| 10 | Sensing Mechanism of Excited-State Intermolecular Hydrogen Bond for Phthalimide: Indispensable Role of Dimethyl Sulfoxide显示文摘Excited-state hydrogen bond strongly affects the intramolecular charge conversion process,which is very suitable for the design and development of high-performance fluorescent probes.However,as one of the most common solvents or additives used in sensing,the role of dimethyl sulfoxide(DMSO)in the system of the excited-state hydrogen bond is seldom explored.As the goal of this research,we investigated the sensing mechanism of a C0RM3-green fluorescent probe system for carbon monoxide releasing molecule(CORM-3)detection and tracking in vivo,through quantum chemistry calculations based on density-functional-theory(DFT)/time-dependent density-functional-theory(TDDFT)methods.Based on the analysis of the solvent effect of DMSO by the reduced density gradient function and IR spectroscopy,we provided a new strategy to explain the fluorescence mechanism.Subsequently,we verified the result through the potential energy curve of Phthalimide(PTI,the reduced product of C0RM3-green).The excited-state hydrogen bond between PTI and DMSO promotes radiation transition and leads to obvious difference in the photophysical properties of PTI and PTI-DMSO. | Dongdong Wang Tianxin Bai Xue Wang Yuting Xiong Yahui Zhang Zhenqiang Shi Fusheng Zhang Wenqi Lu Guangyan Qing | 2021 | Chinese Journal of Chemistry2021，39，5： | 0 |
| 11 | On acoustic performance for viscoelastic coating containing axisymmetric cavities using the multiple scattering method显示文摘A semi-analytical/numerical model based on the multiple scattering(MS) method has been established for analyzing the effect of acoustic performance on main energy attenuation mechanism in viscoelastic coating containing axisymmetric cavities.The basic functions of stress and displacement of the axisymmetric cavity surface are derived in the system of spherical coordinates.The transition matrix between the incident wave and the scattering wave are obtained by the numerical integral of the basic functions of the cavity surface.The reflection,transmission and absorption performance of viscoelastic materials containing periodic cavities are calculated using the MS method and the wave propagating theory of the multi-layered medium.The results indicate that low frequency energy is mainly attenuated through cavity resonance.The resonant properties are found to be very sensitive to the boundary conditions.The coupling of the double-cavity is capable of extending the absorption to even lower frequencies.The absorption performance of the viscoelastic coating in the high frequency range is independent of the backing material.Its energy attenuation depends mainly on acoustic properties of cavity scattering and mode conversion. | BAI Guofeng LIU Bilong SUI Fusheng LIU Ke YANG Jun | 2013 | Chinese Journal of Acoustics2013，32，4： | 0 |
| 12 | Effect of initial orientation on microstructure and mechanical properties of AZ31 Mg alloy sheets via accumulated extrusion bonding显示文摘In this study,effects of initial orientation on microstructure evolution and mechanical properties of AZ31 Mg alloy sheets via accumulated extrusion bonding(AEB)was systematically studied.The samples with RD and TD parallel to extrusion direction(ED)were labeled as RED and TED,respectively.RD and TD pieces alternately stacked was named as RTED.The results revealed that under three-dimensional compressive stress,{10-12}tensile twinning dominated the first stage deformation in container.As the plunger continuous press down,dynamic recrystallization(DRX)occurred,and the newly fine DRXed grains along original and twin grain boundaries gradually consumed the matrix and twin grains.The microstructure was completely transformed into recrystallized grain structure at sizing band with an average grain size of∼0.9μm in TED sample,smaller than that of RED sample.After the alloys extruded out of the die,DRXed grains significantly grew to∼4.5μm and 3.5μm for RED and TED samples,respectively.A laminated microstructure was obtained with average grain sizes of∼4.4μm in RD layers and 3.5μm in TD layers for RTED sample.The AEB processed samples exhibited an ED-tilt double-peak basal texture with similar texture intensity.The tensile tests results indicated that attributed to the combined effect of grain refinement and texture evolution,the yield strength and fracture elongation of RED and TED samples was significantly improved.The heterogeneous microstructure in RTED sample induced an extra work hardening(HDI-work hardening)in tensile deformation and resulted in a further improved elongation of 32.0%. | Xia Cao Tingzhuang Han Ji Xua Guangsheng Huang Hua Zhang Jianhui Bai Fusheng Pan | 2023 | Progress in Natural Science:Materials International2023，33，2： | 0 |
| 13 | Improved Corrosion Resistance of Ultrafine-Grained Mg-Gd-Zr Alloy Fabricated by Surface Friction Treatment显示文摘Gradient ultrafine-grained (UFG) Mg-2Gd-0.4Zr (wt%) alloy sheet, with a UFG layer of about 118 nm on the topmost treated surface, was fabricated by sliding friction treatment (SFT). The corrosion resistance of the SFT-processed UFG surface layer was greatly improved compared to the original coarse-grained (CG) structure, representing as a higher impedance and a lower corrosion rate (CG: 4.11 mm y^(−1), UFG: 2.71 mm y^(−1)). The UFG layer with high density of grain boundaries exhibits an excellent impeditive effect on the cracking of corrosion product films. Compared to the CG sample, the stable corrosion product film inhibits the formation of pitting so providing a better protective effect. In addition, the Gd-rich clusters are randomly distributed after SFT processing, which decreases the tendency of galvanic corrosion on the UFG surface. | Chunquan Liu Xianhua Chen Yulong Wu Yaobo Hu Wei Zhang Yusheng Zhang Jingying Bai Fusheng Pan | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，8： | 0 |
