| 1 | Effect of forging temperature on the microstructures and mechanical properties of the SiC_p/AZ91 magnesium matrix composite显示文摘In this paper,10 vol.pct SiCp/AZ91 magnesium matrix composite was fabricated by stir casting technology.The ingots were forged at temperatures of 320,370 and 420℃,respectively.XRD,OM and SEM were used to characterize microstructure of the composites.It was shown that the clusters of particles in the as-cast composite were largely eliminated,and that the tensile strength was improved obviously. | Kun WU Kunkun DENG Hai CHANG Yewei WU Xiaoshi HU Mingyi ZHENG | 2010 | Acta Metallurgica Sinica(English Letters)2010，23，2： | 1 |

| 3 | Numerical modeling of contaminant advection impact on hydrodynamic diffusion in a deformable medium显示文摘The self-weight of solid waste or machine-rolled compaction can induce or trigger contaminant migration in the landfill.Although the consolidation-induced hydraulic gradient driving solution transport has been extensively investigated,little attention has been paid to ion migration caused by its concentration gradient variation.It is necessary to more precisely predict the multi-stage contaminant transports in deforming porous material.Based on the modified Cam-clay model,the proposed fluid-solid coupled model can simulate the elastoplastic deformation behavior of layered kaolinite and KBr solution transport/sorption,and its modeling results were validated by published laboratory data.The solid-fluid interactions were analyzed by comparing various transport manners of K^(+)and Br^(−)from excess pore pressure generation to dissipation.Results reveal that the consolidation process can accelerate KBr solute advection from the contaminated layer into the uncontaminated layer,and then affects the subsequent diffusion,mechanical dispersion and sorption for K^(+)and Br^(−).The simulations also indicate that consolidation-induced solute transport is time-dependent,and therefore the ion diffusion and mechanical dispersion should receive more attention. | Chunguang Wang Shuqing Liu Xingkai Shi Guanglei Cui Hongxu Wang Xing Jin Kunkun Fan Songtao Hu | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，3： | 0 |
| 4 | Nanostructure designing and hybridizing of high-capacity silicon-based anode for lithium-ion batteries显示文摘Lithium-ion batteries have long been used in electronic products and electric vehicles,but their energy density is slowly failing to keep up with demand.Because of its extraordinarily high theoretical specific capacity,silicon is regarded as the most potential next-generation anode material for practical lithium-ion batteries.However,its unavoidable volume expansion issue can cause electrode deformation and loss of electrical contact during cycling,resulting in significant performance reduction.This work reviews and evaluates the modification measures of Si,SiO,and SiO_(2) as anode materials in order to address the challenges that silicon-based anode materials encounter.We not only review their lithium storage mechanism,but also focus on nanostructure designing and hybridizing to improve the electrochemical performance of silicon-based anodes.The silicon-based anodes can exhibit exceptional capacity retention and excellent rate performance after structural optimization and hybridization,which will greatly facilitate their commercial application.Finally,we discuss our thoughts and recommendations for the future development of silicon-based materials. | Longzhi Li Yue Deng Kunkun Hu Bangqiang Xu Nana Wang Zhongchao Bai Xun Xu Jian Yang | 2023 | Progress in Natural Science:Materials International2023，33，1： | 0 |
