| 1 | Thermal Expansion of Al Matrix Composites Reinforced with Hybrid Micro-/nano-sized Al_2O_3 Particles显示文摘The thermal expansion behavior of aluminum matrix composites reinforced with hybrid(nanometer and micrometer) Al_2O_3 particles was measured between 100 and 600℃ and compared to theoretical models.The results revealed that the nanoparticle concentration had significant effect on the thermal expansion behavior of the composites.For the composites with lower nanoparticle concentration,their coefficient of thermal expansion(CTE) is determined by a stress relaxation process.While for the composites with higher nanoparticle concentration,their CTE is determined by a percolation process. | Zhibo Lei Ke Zhao Yiguang Wang Linan An | 2014 | Journal of Materials Science & Technology2014，30，1： | 6 |

| 3 | Microstructure and Tribological Behavior of Al2O3 Particle Reinforced Al Matrix Composites Fabricated by Spark Plasma Sintering显示文摘Nanoparticles and microparticles reinforced Al matrix composites were fabricated by spark plasma sintering, and the microstructure and tribological properties were investigated systemically. The nano-Al2O3 particle and micro-Al2O3 particle uniformly dispersed in Al matrix composites. The introduction of nanoparticles is beneficial to the decrease of friction coefficient and wear rate, while microparticles are responsible to the high friction coefficient, resulting in the abrasive wear. With the introduction of both nanoparticles and microparticles, their synergic effect will lead to the variation of tribological behavior. | 杨坤 AN Linan CHENG Laifei | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，5： | 2 |
| 4 | Strengthening Mechanisms of 15 vol.% Al_(2)O_(3) Nanoparticles Reinforced Aluminum Matrix Nanocomposite Fabricated by High Energy Ball Milling and Vacuum Hot Pressing显示文摘Increasing nanoparticle volume fraction has been proved to be effective in improving the strength of nanoparticle reinforced Al matrix nanocomposite. However, the underlying mechanisms for the ultrahigh strength of those nanocomposites with high volume fraction(> 10 vol.%) nanoparticles are short of experimental research. In this study, the strengthening mechanisms of high strength Al matrix nanocomposite reinforced with 15 vol.% Al_(2)O_(3) nanoparticles were investigated experimentally and analyzed theoretically. The results show that the thermal mismatch induced geometrically necessary dislocations exhibit a negligible strengthening effect, because of their low density in the nanocomposite that is contradiction to the conventional dislocation punch model. Orowan mechanism makes a major strengthening contribution in view of the deformation process dominated by nanoparticle-dislocation interactions due to the extreme pinning effect of nanoparticles on dislocation motion. In addition, the several mechanisms including grain boundary strengthening, load transfer strengthening, and elastic modulus mismatch induced dislocation strengthening contribute to the strength increase. | Ke Zhao Zhongying Duan Jinling Liu Guozheng Kang Linan An | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，6： | 1 |

| 7 | Electrical-field induced nonlinear conductive behavior in dense zirconia ceramic显示文摘The effect of the applied electric field on the conductive behavior of zirconia ceramics is studied by measuring its initial current-voltage curve at various temperatures. The results show that when the field strength is higher than the threshold for flash-sintering, the curves exhibit a nonlinear behavior by having an additional current on top of the linear current according to Ohm's law. Analyzing its transport behavior reveals that the additional current density is due to the extra oxygen vacancies induced by the electric field. The formation rate of the extra vacancies and associated current was related to the field strength. | Yan Gao Fangzhou Liu Dianguang Liu Jinling Liu Yiguang Wang Linan An | 2017 | Journal of Materials Science & Technology2017，33，8： | 1 |
| 8 | Synthesis of Non-oxide Porous Ceramics Using Random Copolymers as Precursors显示文摘In this paper,we reported a novel method for synthesis of non-oxide porous ceramics by using random copolymers as precursors.A silazane oligomer and styrene monomer were used as starting materials,which were copolymerized at 120 ℃ to form random polysilazane-polystyrene copolymers.The copolymers were then pyrolyzed at 500 ℃ to obtain porous ceramics by completely decomposing polystyrene(PS) and converting polysilazane(PSZ) into non-oxide Si-C-N ceramics.The obtained material contained a bi-model pore-structure consisting of both micro-sized and nano-sized pores with very high surface area of more than500 m^2/g.We also demonstrated that the pore structure and surface area of the materials can be tailored by changing the ratio of the two blocks.Current results suggest a promising simple method for making multiscaled porous non-oxide materials. | Xiaoqian Wang Kewei Wang Jie Kong Yiguang Wang Linan An | 2015 | Journal of Materials Science & Technology2015，31，1： | 1 |

| 10 | Comparative study of flexural strength test methods on CAD/CAM Y-TZP dental ceramics显示文摘Clinically,fractures are the main cause of computer-aided design and computer-aided manufacturing(CAD/CAM)3 mol%-yttria-stabilized tetragonal zirconia polycrystal(Y-TZP)all-ceramic dental restorations failure because of repetitive occlusal loading.The goal of this work is to study the effect of test methods and specimen’s size on the flexural strength of five ceramic products.Both biaxial flexure test(BI)and uni-axial flexure tests(UNI),including three-point flexure test(3PF)and four-point flexure test(4PF),are used in this study.For all five products,the flexural strength is as follows:BI>3PF>4PF.Furthermore,specimens with smaller size(3PF-s)have higher values than the bigger ones(3PF).The difference between BI and UNI resulted from the edge flaws in ceramic specimens.The relationship between different UNI(including 3PF-s,3PF and 4PF)can be explained according to Weibull statistical fracture theory.BI is recommended to evaluate the flexural strength of CAD/CAM Y-TZP dental ceramics. | Yongxiang Xu Jianmin Han Hong Lin Linan An | 2015 | Regenerative Biomaterials2015，2，4： | 1 |
| 11 | Deformation and failure behavior of heterogeneous Mg/SiC nanocomposite under compression显示文摘The heterogeneous magnesium(Mg) matrix nanocomposite with dispersed soft phase exhibits high strength and toughness. Herein, the deformation behavior and failure process were investigated to reveal the unique mechanical behavior of the heterogeneous microstructure under compression. The extensive plastic deformation is accompanied by the flattening and tilting of the soft phase, inhibiting strain localization and leading to strain hardening. Moreover, a stable crack multiplication process is activated, which endows high damage tolerance to the heterogeneous Mg matrix nanocomposites. The final failure of the composite is caused by crack coalescence in the shear plane along a tortuous path. The presence of dispersed soft phases within the hard matrix induces a noticeable change in mechanical response. Especially,the malleability of the heterogeneous Mg matrix nanocomposite is two and ten times higher than that of pure Mg and the homogeneous Mg matrix nanocomposite, respectively. The current study provides a novel strategy to break the trade-off between strength and toughness in metal matrix nanocomposites. | Xi Luo Jinling Liu Leigang Zhang Xu He Ke Zhao Linan An | 2022 | Journal of Magnesium and Alloys2022，10，12： | 1 |
| 12 | Ceramic Nanocomposites Reinforced with a High Volume Fraction of Carbon Nanotubes显示文摘Multi-walled carbon nanotubes(MWNTs) were incorporated into precursor-derived ceramics made from a polysilazane.A ceramic nanocomposite reinforced with about 35 vol%of carbon nanotubes(CNTs)was fabricated by infiltrating CNT-preform with liquid-phased polymeric precursor followed by pyrolysis.The nanocomposite has a dense structure without micro-cracks.The results reveal that the nanocomposite has lower indentation hardness but higher fracture energy than non-reinforced ceramic from the microindentation tests results.The effect of the CNTs on the mechanical properties of the nanocomposite should be discussed accordingly. | 杨坤 CHENG Laifei AN Linan SHAO Gang | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，1： | 1 |

| 14 | Micromechanical simulation on strength and ductility of two kinds of Al-based nanostructural materials显示文摘The nanostructured Al-based composites possess the combination of high yield strength and good ductility. In this paper, a micromechanical model is presented to simulate the mechanical response of bimodal nanostructured Al and the particle-reinforced aluminum matrix composite(PAMC). The constitutive relations for different phases are addressed in the model, as well as the contribution of microcracks. Numerical results show that the model can successfully describe the enhanced strength and ductility of the bimodal nanostructured Al, and the predictions of the PAMC are in good agreement with the experimental data. It is worth noting that the strength and ductility are sensitive to the volume fraction of constituents and the distribution of microcracks in both bimodal nanostructured Al and PAMC. Therefore, the present theoretical results can be used to optimize the microstructure for improving the mechanical properties of nanostructured Al-based composites. | Xu He Linli Zhu Jinling Liu Linan An | 2017 | Acta Mechanica Solida Sinica2017，30，4： | 0 |
| 15 | Ca^2+ doping effects in(K,Na,Li)(Nb0.8Ta0.2)O3 lead-free piezoelectric ceramics显示文摘Lead-free(K0.5-x/2Na0.5-x/2Lix)(Nb0.8Ta0.2)O3(KNLNT)and(K0.49-x/2Na0.49-x/2-LixCa0.01)(Nb0.8Ta0.2)O3(KNLNT-Ca)ceramics were prepared by a conventional ceramic processing.Structural analysis shows that the Ca^2+ doping takes the A site of ABO3 perovskite and decreases the phase transition temperature.Property measurements reveal that as a donor dopant,the Ca^2+ doping results in higher room-temperature dielectric constant,lower dielectric loss,and lower mechanical quality factor.In addition,the Ca^2+ doping does not change the positive piezoelectric coefficient d33,but increases the converse piezoelectric coefficient d 33*significantly.This is likely due to the increase in the relaxation,as well as the appearance of(CaNa/K·-VNa/K’)defect dipoles. | Lei TANG Tengfei LIU Jinxu MA Xiaowen ZHANG Linan AN Kepi CHEN | 2019 | Frontiers of Materials Science2019，13，4： | 0 |
| 16 | In-situ synthesis of Al(76.8)Fe(24) complex metallic alloy phase in Al-based hybrid composite显示文摘The complex metallic alloy(CMA), Al_(76.8)Fe_(24), was in-situ synthesized in the Al-based hybrid composite by powder metallurgy technique. The structural analysis by X-ray diffraction, scanning electron microscopy,and transmission electron microscopy indicated that the Al_(76.8)Fe_(24) CMA phase was formed by diffusion of Fe atoms into the Al matrix during the sintering stage. The formation of the CMA phase was mainly determined by the sintering temperature which was just above the eutectic temperature of Al–Fe. Moreover,the fully dense Al-based hybrid composite was obtained and exhibited ultrahigh strength ~1100 MPa,indicating that this method is expected to be effective in producing CMA particle reinforced Al-based hybrid composite. | Ke Zhao Baobao Cao Jinling Liu Yiguang Wang Linan An | 2017 | Journal of Materials Science & Technology2017，33，10： | 0 |
