| 1 | Comparative study on the interface and mechanical properties of T700/Al and M40/Al composites显示文摘T700/Al and M40/Al composites were fabricated by squeeze casting technology, and their interface and mechanical properties were investi-gated comparatively. The results showed that both of the composites were dense, and the fibers were distributed uniformly in aluminum ma-trix. Aluminum carbide (Al4C3) was observed on the interface of the two carbon fiber-reinforced aluminum (Cf/Al) composites. There was little Al4C3 with a length of 300-500 nm and a width of 30-60 nm in the M40/Al composite, whereas there was a great deal of Al4C3 with a length of 200-400 nm and a width of 100-200 nm in the T700/Al composite, due to a higher graphitization of M40Cf than T700Cf. The M40/Al composite showed a much higher tensile strength than the T700/Al composite, and it was related to interfacial bonding between carbon fibers and aluminum matrices. | ZHANG Yunhe WU Gaohui | 2010 | Rare Metals2010，29，1： | 8 |
| 2 | Microstructure and Mechanical Properties of 45 vol.%SiC_p/7075Al Composite显示文摘Microstructure and mechanical behavior of high volume content Si Cp/7xxx Al composites have not been explored yet. Therefore, in the present work, 45 vol.% SiC p/7075 Al composite has been prepared by pressure infiltration method. High density dislocations were found around Si C/Al interface in SiC p/7075 Al composite after water-quenching and aging treatment. Fine dispersed nano-η′ phases were observed after the aging treatment. Adverse to other Si Cp/Al composites prepared by the pressure infiltration method,an interface layer was observed between SiC particles and Al matrix. Furthermore, high-resolution transmission electron microscopy(HRTEM) observation indicated that this interface layer was coherent/semicoherent with that of the SiC particles. 45 vol.% SiC p/7075 Al composite demonstrated high tensile strength(630 MPa) and micro-ductility. Compared to aged Si Cp/2024 Al composite, the aged Si Cp/7075 Al composite showed an increase of about 200% in the tensile strain and 90% in the tensile strength, respectively.It is speculated that nano-η′ phases in the Al matrix significantly contributed to the strengthening effect while the interface layer between Si C and Al matrix might be beneficial to the strength and plasticity of Si Cp/7075 Al composite. | Ziyang Xiu Wenshu Yang Ronghua Dong Murid Hussain Longtao Jiang YongXing Liu Gaohui Wu | 2015 | Journal of Materials Science & Technology2015，31，9： | 7 |
| 3 | Mechanical Properties of C_f/Mg Composites Fabricated by Pressure Infiltration Method显示文摘The carbon fibers and the woven reinforced magnesium matrix composites were fabricated by pressure infiltration method.Effects of fiber species,fiber arrangement,hybrid particles and environment temperature on microstructures and properties of the composite were studied.Results showed that the mechanical properties at ambient temperature were affected by interfacial reaction.The magnesium matrix composites reinforced with graphite fibers showed higher strength and elastic modulus due to less interfacial reaction.During loading,the fibers were pulled out and the load was transferred through the interfaces,then the fiber bundles were fractured,finally the whole specimen failed.The introduction of hybrid SiC particles during fabrication can improve the mechanical properties of the magnesium matrix composites.Moreover,taking orthogonal carbon fiber woven as reinforcement can modify the anisotropy and reliability of materials. | Meihui Songt Gaohui Wu Wenshu Yang Wei Jia Ziyang Xiu Guoqin Chen | 2010 | Journal of Materials Science & Technology2010，26，10： | 6 |
| 4 | Microstructure and Tensile Properties of Yttria Coated-Alumina Particulates Reinforced Aluminum Matrix Composites显示文摘The liquid-phase coating method was used to deposit Y2O3 ceramic on the surface of α-Al2O3. The coatedAl2O3p/6061Al composites were produced using squeeze casting technology. The microstructure and tensile properties of the composites were analysed and studied. The results showed that the coated Al2O3 particles are able to disperse homogeneously in the aluminum liquid. The microstructure of the composites is more even in comparison with that of as-received powders. The tensile testing indicated that mechanical properties of the coated-Al2O3p/6061Alcomposites are better than those of uncoated particles. In the composite with 30% volume fraction, the tensile strength, yield strength as well as elongation is increased by 29.8%, 38.4% and 10.3%, respectively. The SEM analysis of fracture indicated that the dimples of the coated-Al2O3p/6061Al composites are more even. | Zhiqiang YU, Gaohui WU, Longtao JIANG and Dongli SUNSchool of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, ChinaPresent address: Department of Materials Science, Fudan University, Shanghai 200433, ChinaPh.D., to | 2005 | Journal of Materials Science & Technology2005，21，1： | 2 |
| 5 | Reaction procedure of a graphite fiber reinforced Ti-Al composite produced by squeeze casting-in situ reaction显示文摘The in situ reaction procedure and microstructure evolution of a graphite fiber reinforced Ti-Al composite (Grf/Ti-Al) was investigated, and the stability of TiAl3 at high temperature was discussed. As-cast material was prepared by pressing molten pure aluminum into a preform, which was composed of titanium particles and graphite fibers. The in situ reaction procedure of the as-cast material was investigated by differential scanning calorimetry (DSC), and phases in the products were detected by X-ray diffraction (XRD). Experimental results showed that TiAl3 was formed first. With an increase in temperature, TiC and Al4C3 were observed, but TiAl3 decreased. In the final product, Al2O3 and TiO2 were observed. It was considered that the previous forming TiAl3 decomposed, then TiC precipitated, and subsequently, oxidation resulted in the formation of Al2O3 and TiO2. | WU Gaohui LIU Yanmei XIU Ziyang JIANG Longtao YANG Wenshu | 2010 | Rare Metals2010，29，1： | 2 |
| 6 | Research progress in interface modification and thermal conduction behavior of diamond/metal composites显示文摘Diamond/metal composites are widely used in aerospace and electronic packaging fields due to their outstanding high thermal conductivity and low expansion.However,the difference in chemical properties leads to interface incompatibility between diamond and metal,which has a considerable impact on the performance of the composites.To improve the interface compatibility between diamond and metal,it is necessary to modify the interface of composites.This paper reviews the experimental research on interface modification and the application of computational simulation in diamond/metal composites.Combining computational simulation with experimental methods is a promising way to promote diamond/metal composite interface modification research. | Ping Zhu Pingping Wang Puzhen Shao Xiu Lin Ziyang Xiu Qiang Zhang Equo Kobayashi Gaohui Wu | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，2： | 2 |
| 7 | Study on the Thermal Expansion and Thermal Cycling of AlNp/Al Composites显示文摘The AIN particle reinforced aluminum matrix composites with 50% volume fraction were fabricated by squeeze-casting technology. The thermal expansion behavior and its response to thermal cycling were studied between 20℃ and 400℃. Compared with four theoretical models, the measured CTEs of the composite lie within the elastic bounds derived by Schapery's analysis. Schapery's model and Kerner's model agree well with the CTEs of the composites at lower temperature and elevated temperature, respectively. Strain hysteresis was observed between heating and cooling curves during cycling. This was attributed primarily to the anelastic behavior of the matrix induced by matrix residual stresses. | Qiang ZHANG, Gaohui WU, Dongli SUN and Bofeng LUANSchool of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China | 2002 | Journal of Materials Science & Technology2002，18，1： | 2 |
| 8 | Damping properties of fly ash/epoxy composites显示文摘An inexpensive fly ash (FA), which is from a waste product, was employed to prepare fly ash/epoxy composites. The purpose of this study is to characterize the contributions of matrix viscoelasticity, hollow structure characteristic (porosity), and filler/matrix interface friction to the high vibration damping capacity of such composites. The damping properties of the composites were investigated in the temperature range of -40 to 150°C and in the frequency range of 10 to 800 Hz by using a tension-compression mode. The results indicate that the peak value of damping loss factor (tanδ) for the fly ash/epoxy composites can reach 0.70-0.90 in test specification, and the attenuation of damping loss factor is inconspicuous with increasing frequency. In addition, scanning electron microscope (SEM) was used to observe the morphology of the fly ash as well as its distribution in the matrix, which will help to analyze the effect of fly ash on the damping properties of the fly ash/epoxy composites. | Jian Gu Gaohui Wu Xiao Zhao | 2008 | Journal of University of Science and Technology Beijing2008，15，4： | 2 |
| 9 | Microstructure and Properties of M40 Carbon Fibre Reinforced Mg-Re-Zr Alloy Composites显示文摘M40 carbon fibre reinforced rare earth magnesium alloy ZM6 composites with fibre volume fraction about 60% were fabricated by pressure infiltration method. The microstructure, interfacial morphology, and precipitation were studied by scanning electron microscopy, transmission electron microscopy, and energy dispersive X-ray spectrometer. It was shown that the interfaces between Mg alloy and fibres were well bonded and free from cracks. The Mg12Nd phase was preferentially precipitated at the fibre/matrix interfaces, leading to the segregation of Nd at the interfaces and the dramatic decrease of Mg12Nd precipitation in the matrix far from interfaces. Crystal defects such as high-density dislocations and twins were observed in the matrix near the fibre/matrix interface. A high bending strength (1393 MPa) and elastic modulus (190 GPa) were achieved in M40/ZM6 composite. | Gaohui Wu Meihui Song Ziyang Xiu Ning Wang Wenshu Yang | 2009 | Journal of Materials Science & Technology2009，25，3： | 2 |

| 11 | Fabrication of in situ Ti_2AlN/TiAl Composites by Reaction Hot Pressing and Their Properties显示文摘Ti2AlN/TiAl composites with different volume fractions of reinforcement were successfully fabricated by hot-pressing sintering method(reaction hot pressing) using Ti, Al and TiN powders as starting materials. The synthesis process includes four stages: first, the reactions between Al and Ti powers and between Al and TiN powders respectively occur and result in TiAl3 phase; secondly, Al powders in the sample are exhausted; the remaining Ti cores react with TiAl3 layer to form Ti-Al intermetallics; moreover, a few Ti2AlN particles precipitate from the TiAl3 phase; thirdly, Ti-Al intermetallics react with the remaining Ti cores to form Ti3Al and TiAl phases. TiAl phase and original TiN powers are in direct contact each other; finally, the residual TiN powers react with TiAl phase and result in a plenty of Ti2AlN phase. Compared with TiAl matrix, the hardness, elastic modulus and high-temperature compressive strength of Ti2AlN/TiAl composite are improved obviously and they are all enhanced with increasing the volume fraction of Ti2AlN phase. | 孙东立 SUN Tao WANG Qing HAN Xiuli GUO Qiang WU Gaohui | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，1： | 1 |
