| 1 | Kinetics and Mechanism of Interfacial Reaction in a SiC_f/Ti Composite显示文摘In order to evaluate the interfacial reaction, a SiCf/Ti (TA1) composite was fabricated by a vacuum hot pressingmethod and then heat-treated in vacuum at 800℃ for up to 100 h. The elemental distributions of C, Si and Ti at theinterfacial reaction zone were investigated. It was found that the reaction zone occurs during the fabrication processand continuously grows at high temperature because the Si and C atoms diffuse from SiC fibers to the matrix and Tiatoms diffuse in the opposite direction. The growth of the reaction zone is diffusion controlled and the mechanismof the reaction can be described by a reactive diffusion model of solid-state growth of an AmBn layer between twoelementary substances A and B. | Guoxing ZHANG, Qiang KANG, Nanlin SHI, Geping LI and Dong LIInstitute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China | 2003 | Journal of Materials Science & Technology2003，19，5： | 7 |

| 3 | Measurement of interfacial residual stress in SiC fiber reinforced Ni-Cr-Al alloy composites by Raman spectroscopy显示文摘Raman spectroscopy was used to measure Raman spectra of the inner SiC fibers and surface C-rich layers of SiC fibers, composite precursors and SiCf/Ni-Cr-Al composites. The residual stresses of the inner SiC fibers and surface C-rich layers were calculated, and the effect of the(Al + Al_2O_3) diffusion barrier layer on the interfacial residual stress in the composites was analyzed in combination with the interface microstructure and energy disperse spectroscopy(EDS) elements lining maps. The results show that the existence of(Al + Al_2O_3) diffusion barrier improves the compatibility of the SiCf/Ni-Cr-Al interface,inhibits the adverse interfacial reaction, and relieves the residual stress inside SiC fibers and at the interface of composite material. Heat treatment can reduce the residual stress at the interface. As the heat treatment time increases, the residual stress at the interface decreases. | Xixi Niu Haoqiang Zhang Zhiliang Pei Nanlin Shi Chao Sun Jun Gong | 2019 | Journal of Materials Science & Technology2019，35，1： | 3 |

| 5 | An effective strategy towards construction of CVD SiC fiber-reinforced superalloy matrix composite显示文摘In this work,a modified approach for preparing CVD SiC fiber-reinforced superalloy matrix composites was rationally developed.The composites were fabricated by vacuum hot pressing(VHP)process using precursor wires coated with(Al+Al2O3)diffusion barrier layers and GH4169 superalloy coatings.BNi-7 brazing filler metals were introduced on the surface of precursor wires in order to decrease the temperature of the VHP process.It was found that the VHP temperature was reduced by about 100℃,and the melting,diffusion,nucleation and growth processes of BNi-7 fillers at 900?C motivated the recrystallization and plastic flow of the matrix under the increasing pressure,thereby a compact composite composed of intact SiC fibers and fine equiaxial grain structure superalloy matrix was achieved.Meanwhile,the elements were distributed homogeneously among the fibers in the composite and no interfacial reactions occurred.This method provides a new insight for designing and manufacturing high-quality composites in practical engineering. | Haoqiang Zhang Lin Liu Zhiliang Pei Nanlin Shi Jun Gong Chao Sun | 2020 | Journal of Materials Science & Technology2020，47，14： | 3 |

| 7 | Preparation and Characterization of Polyaniline Nanofibers by Template-free Method显示文摘In the presence of p-toluene sulfonic acid (TSA) as a dopant, polyaniline (PAni) nanofibers, (about 80~165 nm in diameter) were successfully synthesized with a chemical template-free method. It was found that the formation probability, morphology, and diameter of the resulting PAni-TSA nanofibers were sensitive to the synthetic conditions,such as reaction temperature, the molar ratio of TSA to aniline, and the concentration of TSA in the polymerization media. The molecular structure was characterized by using the FT-IR, Raman spectra and X-ray diffraction, which shows that the main chain structure of PAni-TSA nanofibers was in agreement with that of granular PAni. | Xuemei GUO, Kun LUO and Nanlin SHI Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China | 2005 | Journal of Materials Science & Technology2005，21，2： | 2 |

| 10 | Preparation of SiC Fiber Reinforced Nickel Matrix Composite显示文摘A method of preparing continuous(Al+Al2O3)-coated SiC fiber reinforced nickel matrix composite was presented,in which the diffusion between SiC fiber and nickel matrix could be prevented.Magnetron sputtering is used to deposit Ni coating on the surface of the(Al+Al2O3)-coated SiC fiber in preparation of the precursor wires.It is shown that the deposited Ni coating combines well with the(Al+Al2O3) coating and has little negative effect on the tensile strength of(Al+Al2O3)-coated SiC fiber.Solid-state diffusion bonding process is employed to prepare the(Al+Al2O3)-coated SiC fiber reinforced nickel matrix with 37% fibers in volume.The solid-state diffusion bonding process is optimized and the optimum parameters are temperature of 870,pressure of 50 MPa and holding time of 2 h.Under this condition,the precursor wires can diffuse well,composite of full density can be formed and the(Al+Al2O3) coating is effective to restrict the reaction between SiC fiber and nickel matrix. | Lu Zhang Nanlin Shi Jun Gong Chao Sunt | 2012 | Journal of Materials Science & Technology2012，28，3： | 1 |

| 14 | Effects of Cr and Al Contents on the Preparation of SiC Fiber-Reinforced NiCrAl Alloy Matrix Composite显示文摘In this work,the effects of Cr and Al contents on the preparation of SiC fiber-reinforced NiCrAl alloy matrix composites(SiCf/Ni-20Cr-5Al,SiCf/Ni-15Cr-5Al,SiCf/Ni-10Cr-5Al and SiCf/Ni-10Cr-3Al)were thoroughly discussed.The composites were prepared by vacuum hot pressing process using matrix-coated fibers.It was found that Cr solute atoms played a significant role in retarding the recrystallization of NiCrAl alloy matrix,and the Al elements in the form of γ'-Ni3Al phase had a suppression effect on the plastic flow of the matrix.Therefore,the reduction in Cr and Al contents was conductive to the recrystallization and plastic flow of NiCrAl alloy matrix,thereby reduced the size and number of micro-voids in the composite.In addition,this work provides some guidance for designing and manufacturing reasonable SiC fiber-reinforced Ni alloy matrix composites. | Haoqiang Zhang Xixi Niu Zhiliang Pei Nanlin Shi Jun Gong Chao Sun | 2020 | Acta Metallurgica Sinica(English Letters)2020，33，10： | 0 |

| 16 | CORRELATION BETWEEN TENSILE STRENGTH AND SURFACE MORPHOLOGY OF SiC FILAMENT显示文摘The surface morphology of the continuous SiC filament,prepared by radio frequency heatingCVD technique,has been observed and the tensile strength of the filament related to thetechnological parameters of preparation has also been investigated.The tensile strength isfound to be dependent directly upon the surface smoothness,grain size and uniformity.How-ever,the CVD temperature,the composition and flow rate of reactive gases,as well as thecleansing of W wire substrate,etc.,are the very important factors.A protective layer coatedover the outer surface of SiC filament may effectively improve the smoothness,susceptibilityto surface damage and properties of the SiC filament. | SHI Nanlin LIU Qingmin CHANG Xinchun QUAN Rong XIA Fei Institute of Metal Research,Academia Sinica,Shenyang,China | 1990 | Acta Metallurgica Sinica(English Letters)1990，3，12： | 0 |
| 17 | Effects of Substrate Temperature on the Growth of Polycrystalline Si Films Deposited with SiH_4+Ar显示文摘Polycrystalline silicon(poly-Si) films were deposited using Ar diluted SiH4 gaseous mixture by electron cyclotron resonance plasma-enhanced chemical vapor deposition(ECR-PECVD).The effects of the substrate temperature on deposition rate,crystallinity,grain size and the configuration of H existing in poly-Si film were investigated.The results show that,comparing with H2 dilution,Ar dilution could significantly decrease the concentration of H on the growing surface.When the substrate temperature increased,the deposition rate increased and the concentration of H decreased monotonously,but the crystallinity and the grain size of poly-Si films exhibited sophisticated trends.It is proposed that the crystallinity of the films is determined by a competing balance of the self-diffusion activity of Si atoms and the deposition rate.At substrate temperature of 200℃,the deposited film exhibits the maximum poly-Si volume fraction of 79%.Based on these results,higher substrate temperature is suggested to prepare the poly-Si films with advanced stability and compromised crystallinity at high deposition rate. | Hua Cheng Aimin Wu Jinquan Xiao Nanlin Shi Lishi Wen | 2009 | Journal of Materials Science & Technology2009，25，4： | 0 |
| 18 | Sea Cucumber-like Polyaniline Nanofibers Synthesized by Aqueous Solution Method显示文摘The preparation of polyaniline nanofibers in aqueous solution was studied as functions of the concentrations and ratios of reactants. The morphology and microstructure of polyaniline nanofibers are affected by the concentrations and proportions of the reactants. A special kind of sea cucumber-like polyaniline nanofibers can be prepared under control of reaction conditions. Secondary growth is the formation mechanism. In addition, the bulk electrical conductivity of these sea cucumber-like polyaniline nanofibers was higher than that of other common polyaniline nanofibers. | Baoyun Liu Li Liu Nanlin Shi Jun Gong Chao Sun | 2010 | Journal of Materials Science & Technology2010，26，1： | 0 |
| 19 | Effect of Ar on Polycrystalline Si Films Deposited by ECR-PECVD using SiH_4显示文摘In this paper,polycrystalline silicon films were deposited by electron cyclotron resonance plasma-enhanced chemical vapor deposition(ECR-PECVD)using SiH_4/Ar and SiH_4/H_2 gaseous mixture.Effects of argon flow rate on the deposition efficiency and the film property were investigated by comparing with H_2.The results indicated that the deposition rate of using Ar as discharge gas was 1.5-2 times higher than that of using H_2, while the preferred orientations and the grain sizes of the films were analogous.Film crystallinity increased with the increase of Ar flow rate.Optimized flow ratio of SiH_4 to Ar was obtained as F(SiH_4):F(Ar)=10:70 for the highest deposition rate. | Hua CHENG Aimin WU Nanlin SHI Lishi WEN | 2008 | Journal of Materials Science & Technology2008，24，5： | 0 |
| 20 | Interfacial Interaction in Coated Carbon Fibre Reinforced Aluminous Mg-based Composites显示文摘Four kinds of Mg alloys reinforced with carbon fibres were fabricated by a gas pressure infiltration technique. The fibres were pre-coated a SiO_2 layer prior to fabrication.Different microstructures and interactions in the fibre-matrix interface of these composites were observed by transmission electron microscopy (TEM). The results showed that the interracial interaction strongly depended on the content of Al in the Mg-based matrices.The microstructure of the interface could then be controlled by adjusting the Al content of the Mg- based matrix.In addition,fibres extracted from different Mg-based matrix all had some degradation owing to the interracial reaction and the fibre-matrix interdiffusion. | Kun LI Nanlin SHI Jun GONG Chao SUN | 2008 | Journal of Materials Science & Technology2008，24，6： | 0 |
