| 2 | Deposition of FeCoNiCrMn high entropy alloy(HEA) coating via cold spraying显示文摘High entropy alloys(HEAs) are of great interest in the community of materials science and engineering due to their unique phase structure. They are constructed with five or more principal alloying elements in equimolar or near-equimolar ratio. Therefore, HEAs can derive their performance from multiple principal elements rather than a single element. In this work, solid-state cold spraying(CS) was applied for the first time to produce FeCoNiCrMn HEA coating. The experimental results confirm that CS can be used to produce a thick HEA coating with low porosity. As a low-temperature deposition process, CS completely retained the HEA phase structure in the coating without any phase transformation. The characterization also reveals that the grains in the CSed HEA coating had experienced significant refinement as compared to those in the as-received HEA powder due the occurrence of dynamic recrystallization at the highly deformed interparticle region. Due to the increased dislocation density and grain boundaries,CSed HEA coating was much harder than the as-received powder. The tribological study shows that the CSed FeCoNiCrMn HEA coating resulted in lower wear rate than laser cladded HEA coatings. | Shuo Yin Wenya Li Bo Song Xingchen Yan Min Kuang Yaxin Xu Kui Wen Rocco Lupoi | 2019 | Journal of Materials Science & Technology2019，35，6： | 13 |
| 3 | 颗粒团聚对Al基SiC颗粒增强复合材料的流变形为影响(英文)显示文摘基于微观组织的有限元分析模型,研究颗粒团聚对Al基SiC颗粒增强金属基复合材料流变行为的影响。通过建立的3种增强颗粒分布的胞元模型(一个团聚现象、两个团聚现象和随机分布),分析讨论基体和增强颗粒中的等效应力和等效应变的分布规律,以此为基础,获得3种颗粒分布模型下的SiC颗粒增强Al基复合材料的应力应变曲线。结果表明:颗粒增强金属基复合材料的流变行为和力学响应与增强颗粒的分布非常敏感,但在弹性变形阶段这种影响就相对较弱。从增强颗粒的最大主应力分布来看,颗粒团聚增加了SiC颗粒开裂的概率。从基体的静水应力分布来看,颗粒团聚将促进早期的界面脱粘和在韧性基体中形成微空洞。 | 张鹏 李付国 | 2010 | 稀有金属材料与工程2010，39，9： | 10 |
| 4 | A Versatile Method for Uniform Dispersion of Nanocarbons in Metal Matrix Based on Electrostatic Interactions显示文摘Realizing the uniform dispersion of nanocarbons such as carbon nanotube and graphene in metals, is an essential prerequisite to fully exhibit their enhancement effect in mechanical, thermal, and electrical properties of metal matrix composites(MMCs). In this work, we propose an effective method to achieve uniform distribution of nanocarbons in various metal flakes through a slurry-based method. It relies on the electrostatic interactions between the negatively charged nanocarbons and the positively charged metal flakes when mixed in slurry. For case study, flake metal powders(Al, Mg, Ti,Fe, and Cu) were positively charged in aqueous suspension by spontaneous ionization or cationic surface modification. While nanocarbons, given examples as carboxylic multi-walled carbon nanotubes, pristine single-walled carbon nanotube, and carbon nanotube–graphene oxide hybrid were negatively charged by the ionization of oxygen-containing functional groups or anionic surfactant. It was found that through the electrostatic interaction mechanism, all kinds of nanocarbons can be spontaneously and efficiently adsorbed onto the surface of various metal flakes. The development of such a versatile method would provide us great opportunities to fabricate advanced MMCs with appealing properties. | Zan Li Genlian Fan Zhanqiu Tan Zhiqiang Li Qiang Guo Dingbang Xiong Di Zhang | 2016 | Nano-Micro Letters2016，8，1： | 5 |
| 5 | Enhanced ductility of Mg–3Al–1Zn alloy reinforced with short length multiwalled carbon nanotubes using a powder metallurgy method显示文摘Mg–3Al–1Zn–CNTs composites, with different weight fractions(0.25–1.0 wt%) of carbon nanotubes(CNTs) were successfully fabricated via a powder metallurgy method. The processing parameters were adopted in such a way to have uniform dispersion of short length CNTs without any damage, as well as re fi ned and dissolved β phases structures throughout the composite matrix. The composite exhibited impressive increase in microhardness(about+23%) and tensile failure strain value(about+98%) without signi fi cant compromise in tensile strength, compared to the un-reinforced Mg–3Al–1Zn alloy. The synthesized composites can be used in automotive and aerospace industries due to their low density and high speci fic strength. | Muhammad Rashad Fusheng Pan Muhammad Asif Li Li | 2015 | Progress in Natural Science:Materials International2015，25，4： | 3 |
| 6 | A novel approach for fabricating a CNT/AlSi composite with the self-aligned nacre-like architecture by cold spraying显示文摘A fully dense carbon nanotubes (CNTs) reinforced AlSi matrix composite with the multiscale nacre-like architecture was designed and successfully realized by flake powder metallurgy followed by cold spraying (CS). The nanolaminated and ultrafine-grained structure initially created in the CNT/AlSi flaky powder was perfectly conserved, due to the typical ‘cold’ feature of CS. As discussed based on finite element analysis and single splat observation, self-alignment behavior of the flaky powders during impact also allowed the formation of the microlaminated structure. Hence, the scalable CS technique opens a new avenue for bioinspired material design and fabrication with complex shape. | Xinliang Xie Chaoyue Chen Gang Ji Run Xu Zhanqiu Tan Yingchun Xie Zhiqiang Li Hanlin Liao | 2019 | Nano Materials Science2019，1，2： | 3 |
| 7 | Interface-dominated mechanical behavior in advanced metal matrix composites显示文摘Metal matrix composites(MMCs)incorporate a reinforcing or functional secondary phase into a metal matrix to achieve specific properties.Of the parameters which may affect the mechanical behavior of MMCs,the structure and properties of the reinforcement/matrix interface play a crucial role.This article reviews recent developments in measuring the interfacial properties in advanced MMCs,with an emphasis on the use of micro-/nano-mechanical testing approaches.It is shown that,with the novel in situ and ex situ experimental capability,researchers can now obtain some of the critical interfacial properties as well as the effects of reinforcement/matrix interfaces on the composites’deformation and failure mechanisms that were unattainable previously by conventional methodologies.Moreover,the micro-/nano-mechanical testing platform allows for both fundamental and applied research on the composites’mechanical performance under service conditions,which is considered a promising and emerging research direction. | Qiang Guo Yifan Han Di Zhang | 2020 | Nano Materials Science2020，2，1： | 3 |
| 8 | Friction stir welding of carbon nanotubes reinforced Al-Cu-Mg alloy composite plates显示文摘Carbon nanotubes(CNTs) reinforced Al-Cu-Mg composite plates of 2.2 mm in thickness after extrusion and T4 treatment were joined by friction stir welding(FSW) and the joint efficiency reaches 87%. There was no precipitate in both heat-affected zone(HAZ) and nugget zone(NZ) as a medium rotation rate of 800 rpm and a relative high travel speed of 100 mm min-1were used. In the NZ, FSW disarranged the alignment of CNTs to random orientation and dispersed CNT uniformly. The orientation of CNTs perpendicular to the tensile direction and the possible dissolution of solute clusters made the HAZ become the weakest zone in the joint leading to the failure in the HAZ. | Ke Zhao Zhenyu Liu Bolyu Xiao Zongyi Ma | 2017 | Journal of Materials Science & Technology2017，33，9： | 2 |

| 10 | Microstructure and mechanical properties of in-situ TiB_2/A356 composites and a prediction model of yield strength显示文摘The in-situ TiB_2/A356 composites were successfully synthesized through the mixed salt reaction method.The advantage of this technique was that the particle sizes and morphology can be controlled by the melt reaction.Therefore,the technique can be designed to obtain expected properties,such as high strength at high and room temperatures,high damping capacity,high modulus and good fatigue life.Results showed that in the as-cast state of A356 alloy and TiB_2/A356 composites,the eutectic Si phase is normally in the needle shape,and TiB_2 particles are mostly in the cubic or near spherical shape,with the size ranging from 30 to 500 nm uniformly distributed in the grains.Also,TiB_2 particle clusters are observed in composites.With an increase in TiB_2particles,the average grain size of composites decreases both in as-cast and T6 state.It is found that both the yield stength and ultimate tensile strength increase with an increase in the TiB_2 volume fraction.On the contrary,the elongation reduces with the addition of TiB_2 particles.Based on the experimental results and Clyne's report,a revised model related to particle strengthening mechanism was proposed to fairly predict yield strengths of TiB_2/A356 composites.The satisfactory agreement between the calculated values and experimental data reported in the literature was obtained. | Yi-jie Zhang Ming-liang Wang Xian-feng Li Dong Chen Nai-heng Ma Hao-wei Wang | 2015 | China Foundry2015，12，4： | 2 |
| 11 | Monitoring Damage Evolution in a Titanium Matrix Composite Shaft Under Torsion Loading Using Acoustic Emission显示文摘The damage behaviors of a titanium matrix composite shaft under torsion loading were monitored using the acoustic emission technique. The composite shaft with SiC fibers at ±45° orientations was prepared by the solid-state fabrication process. Both the torsional rigidity and torsional strength of the TMC shaft were improved by SiC fibers. The acoustic emission responses during the loading-unloading-reloading, under quasi-static and cyclic torsion tests were investigated. Multiple acoustic emission signals were grouped as mechanical noise, matrix deformation, interface debonding and fiber fracture using amplitude, waveform shape and frequency centroid parameters. A substantial reduction of signals generated by matrix deformation was found in the reloading test. During the quasi-static torsion test, interface debonding and progressive breaks of SiC fibers occurred. According to different acoustic emission behaviors, the failure process in the torsion fatigue test can be divided into three stages: the initial stage, the fiber fracture stage and the fast fracture stage. | Xu Kong Yu-Min Wang Xu Zhang Qing Yang Guo-Xing Zhang Li-Na Yang Rui Yang | 2019 | Acta Metallurgica Sinica(English Letters)2019，32，10： | 2 |
| 12 | PULSED Nd-YAG LASER WELDING OF AN AI-SiC_p METAL MATRIX COMPOSITE显示文摘A study is presented of the laser welding behaviour of an SiC particulate re-inforced Al-alloy comPOsite using a pulsed Nd-YAG laser. The influences of laser weldingparameters of laser intensity, pulse duration and the beamjs focus position on the depth ofweld penetration as well as the size of weld bead width were investigated. A typical mi-crostructure of a weld section reveals that the three distinct zones are present. Cracks andporosity were fOund to be two major defects in laser welded metal matrix composites(MMC). These investigations have led to an optimum welding condition proposed forlaser welding of SiC partiulate reinforced aluminium alloy comPosites with minimum de-fects. | Xu Jiukua Jiang Chengyu(Mechanical Engineering Institute, Nanjing University of Aeronauticsand Astronautics, Nanjing, 210016, China)Yu Damin Liu Weicheng(Department of Manufacturing Engineering, Hong Kong Polytechnic University) | 1997 | Chinese Journal of Aeronautics1997，10，1： | 2 |
| 13 | Nano-SiC_P particles distribution and mechanical properties of Al-matrix composites prepared by stir casting and ultrasonic treatment显示文摘Nano-ceramic particles are generally difficult to add into molten metal because of poor wettability. Nano-SiC_Particles reinforced A356 aluminum alloy composites were prepared by a new complex process, i.e., a molten-metal process combined with high energy ball milling and ultrasonic vibration methods. The nano particles were β-SiC_P with an average diameter of 40 nm, and pre-oxidized at about 850 °C to form an oxide layer with a thickness of approximately 3 nm. The mm-sized composite granules containing nano-SiC_P were fi rstly produced by milling the mixture of oxidized nano-SiC_P and pure Al powders, and then were remelted in the matrix-metal melt with mechanical stirring and treated by ultrasonic vibration to prepare the composite. SEM analysis results show that the nano-SiC_P articles are distributed uniformly in the matrix and no serious agglomeration is observed. The tensile strength and elongation of the composite with 2 wt.% nano-SiC_P in as-cast state are 226 MPa and 5.5%, improved by 20% and 44%, respectively, compared with the A356 alloy. | Shu-sen Wu Du Yuan Shu-lin Lü Kun Hu Ping An | 2018 | China Foundry2018，15，3： | 1 |
| 14 | Effect of tool plunge depth on reinforcement particles distribution in surface composite fabrication via friction stir processing显示文摘Aluminium matrix surface composites are gaining alluring role especially in aerospace, defence, and marine industries. Friction stir processing(FSP) is a promising novel solid state technique for surface composites fabrication. In this study, AA6061/SiC surface composites were fabricated and the effect of tool plunge depth on pattern of reinforcement particles dispersion in metal matrix was investigated. Six varying tool plunge depths were chosen at constant levels of shoulder diameter and tool tilt angle to observe the exclusive effect of plunge variation. Process parameters chosen for the experimentation are speed of rotation, travel speed and tool tilt angle which were taken as 1400 rpm, 40 mm/min, and 2.5 °respectively. Macro and the microstructural study were performed using stereo zoom and optical microscope respectively. Results reflected that lower plunge depth levels lead to insufficient heat generation and cavity formation towards the stir zone center. On the other hand, higher levels of plunge depth result in ejection of reinforcement particles and even sticking of material to tool shoulder. Thus, an optimal plunge depth is needed in developing defect free surface composites. | Sandeep Rathee Sachin Maheshwari Arshad Noor Siddiquee Manu Srivastava | 2017 | Defence Technology(防务技术)2017，13，2： | 1 |

| 16 | Wear behavior of light-weight and high strength Fe-Mn-Ni-Al matrix self-lubricating steels显示文摘The good combination of mechanical and tribological properties for self-lubricating materials is crucial. In this work, novel self-lubricating Fe-16.4 Mn-4.8 Ni-9.9 Al-xC(wt%) steels containing graphite phase were fabricated using mechanical alloying and spark plasma sintering. The compositions of the steels were designed by using thermodynamic calculation, and the effect of carbon addition on the microstructure was further investigated. The steel possesses high hardness of 621 HV, high yield strength of 1437 MPa and good fracture toughness at room temperature. The yield strengths are still above 600 MPa at 600?C.The tribological behavior and mechanical properties from room temperature to 800?C were studied, and the wear mechanisms at elevated temperatures were discussed. The steel has a stable friction coefficient of 0.4 and wear rate in a magnitude of 10^(-6) mm^3/N·m below 600?C. The good tribological properties of the steels were mainly attributed to the high hardness, lubrication of graphite and stable surface oxide layer. | Liuliu Han Kun Li Cheng Qian Jingwen Qiu Chengshang Zhou Yong Liu | 2019 | Journal of Materials Science & Technology2019，35，4： | 1 |
| 17 | Microstructure, mechanical and corrosion properties of electron-beam-melted and plasma-transferred arc-welded WC_P/NiBSi metal matrix composites显示文摘As one of the new additive manufacturing processes,electron beam melting(EBM)has seen its promising potential in the fabrication of metal matrix composites(MMCs)components with complex geometries.In this work,WC_P/NiBSi MMCs were fabricated by EBM and plasma-transferred arc welding(PTAW)for a comparative study.The microstructures of both samples were examined using a scanning electron microscope(SEM)equipped with an electron backscattered diffraction(EBSD)detector.The macrohardness was tested using a Rockwell hardness method(Type C),while the microhardness was measured using different loadings(0.5-1.0 N)based on different phases.The anti-abrasion performance was tested as per the ASTM G105 standard.The corrosion behavior of the MMCs was also assessed by potentiodynamic polarization.The results indicate that the EBM bulk and the PTAW cladding MMCs exhibit different microstructures due to the different local solidification conditions.This is believed to lead to the varied mechanical properties and corrosion resistance of the MMCs,and the possible mechanisms were also discussed. | Chang Liu Hui Peng Yue Zhao Yuan Yuan Hong-Bo Guo Hui-Bin Xu | 2019 | Rare Metals2019，38，9： | 0 |

| 19 | Relationship between dispersibility of ZrO2 nanoparticles in Ni-ZrO2 electroplated nanocomposite coatings and mechanical properties of nanocomposite coatings显示文摘Ni-ZrO2 nanocomposite coatings with monodispersed ZrO2 nanoparticles were prepared from the composite plating bath containing dispersant under DC electrodeposition condition. It is found that the morphology, orientation and hardness of the composite coating with monodispersed ZrO2 nanoparticles have lots of difference from the composite coating with agglomerated ZrO2 nanoparticles and pure nickel coating. Especially, the result of hardness shows that only a very low volume fraction (less than 1%) of monodispered ZrO2 nanoparticles in Ni-ZrO2 composite coatings will result in higher hardness of the coating. The hardness of Ni-ZrO2 nanocomposite coatings with monodispersed and agglomerated ZrO2 nanoparticles are HV 529 and HV 393, respectively. The hardness value of the former composite coatings is over 1.3 times higher than that of the later. All these composite coatings are 2 - 3 times higher than that of pure nickel plating (HV 207) prepared under the same conditions. | WANG Wei HOU Feng-yan GUO He-tong | 2004 | 中国有色金属学会会刊:英文版2004，14，z1： | 0 |
| 20 | Residual Stresses and Deformation Behaviour in a SiC_p/Al Composite显示文摘Experiments were conducted to determine theresidual stresses with X-ray diffraction in the ma-trix of a SiC/Al composite after different thermaltreatments,and to investigate the stress-straincharacteristics and fracture behaviour of the com-posite.It was found that there existed a tensileresidual stress in the matrix and both thermal cy-cling between room temperature and 350℃ and lowtemperature treatment in liquid nitrogen reducedthe residual stress.The results of the strengthdifferential effect and Bauschinger effect were con-sistent with the results of residual stressmeasurements.The tensile residual stresses in the Almatrix enhanced the strength differential effect.Themagnitude of Bauschinger effect is greater for a testinitially started in compression than that in tension. | 孙正明 李家宝 王中光 李伟杰 周延春 | 1992 | Journal of Materials Science & Technology1992，8，2： | 0 |
