| 1 | Three principles for preparing Al wire with high strength and high electrical conductivity显示文摘The trade-off relation between the strength and the electrical conductivity has been a Iong-standing dilemma in metallic materials. In the study, three key principles, i.e.elongated grains, sharp texture and nano-scale precipitates, were presented for preparing Al wire with high strength and high electrical conductivity based on the specially designed experiments for breaking the mutually exclusive relation between the strength and the electrical conductivity. The results show that the elongated grains could lead to a higher electrical conductivity in Al wire without sacrificing the strength;while, the <111> sharp texture can efficiently strengthen the Al wire without influencing the electrical conductivity. Furthermore, nano-scale precipitates with proper size can simultaneously improve the strength and electrical conductivity of Al alloy wire. Under the guidance of the above three key principles, Al wires with high strength and high conductivity were prepared. | J.P.Hou R.Li Q.Wang H.Y.Yu Z.J.Zhang Q.Y.Chen H.Ma X.M.Wu X.W.Li Z.F.Zhang | 2019 | Journal of Materials Science & Technology2019，35，5： | 7 |
| 2 | Free electron lasers driven by plasma accelerators:status and near-term prospects显示文摘Owing to their ultra-high accelerating gradients,combined with injection inside micrometer-scale accelerating wakefield buckets,plasma-based accelerators hold great potential to drive a new generation of free-electron lasers(FELs).Indeed,the first demonstration of plasma-driven FEL gain was reported recently,representing a major milestone for the field.Several groups around the world are pursuing these novel light sources,with methodology varying in the use of wakefield driver(laser-driven or beam-driven),plasma structure,phase-space manipulation,beamline design,and undulator technology,among others.This paper presents our best attempt to provide a comprehensive overview of the global community efforts towards plasma-based FEL research and development. | C.Emma J.Van Tilborg R.Assmann S.Barber A.Cianchi S.Corde M.E.Couprie R.D'Arcy M.Ferrario A.F.Habib B.Hidding M.J.Hogan C.B.Schroeder A.Marinelli M.Labat R.Li J.Liu A.Loulergue J.Osterhoff A.R.Maier B.W.J.Mc Neil W.Wang | 2021 | High Power Laser Science and Engineering2021，9，4： | 2 |
| 3 | Effect of stress profile on microstructure evolution of cold-drawn commercially pure aluminum wire analyzed by finite element simulation显示文摘The evolution of microstructure in the drawing process of commercially pure aluminum wire(CPAW)does not only depend on the nature of materials, but also on the stress profile. In this study, the effect of stress profile on the texture evolution of the CPAW was systematically investigated by combining the numerical simulation and the microstructure observation. The results show that the tensile stress at the wire center promotes the formation of <111> texture, whereas the shear stress nearby the rim makes little contribution to the texture formation. Therefore, the <111> texture at the wire center is stronger than that in the surface layer, which also results in a higher microhardness at the center of the CPAW under axial loading. | Y.K.Zhu Q.Y.Chen Q.Wang H.Y.Yu R.Li J.P.Hou Z.J.Zhang G.P.Zhang Z.F.Zhang | 2018 | Journal of Materials Science & Technology2018，34，7： | 2 |

| 6 | Excellent strength-ductility combination in Co_(36)Cr_(15)Fe_(18)Ni_(18)Al_(8)Ti_(4)Mo_(1)multi-principal element alloys by dual-morphology B2 precipitates strengthening显示文摘Precipitation strengthening provides one of the most widely-used mechanisms for strengthen-ing multi-principal-element alloys(MPEAs).Here,we report dual-morphology B2 precipitates in Co_(36)Cr_(15)Fe_(18)Ni_(18)Al_(8)Ti_(4)Mo_(1)MPEA obtained by thermo-mechanical processing.Electron microscopy charac-terization reveals that the dual-morphology B2 precipitates are either recrystallized B2 particles formed at the grain boundaries or triple junctions with recrystallization process,or rod-like within the non-recrystallized FCC matrix.The dual-morphology B2 precipitates enhance the yield strength and ultimate tensile strength up to 1120 MPa and 1480 MPa,respectively.This work suggests the mechanical proper-ties of the alloy can be optimized by B2 precipitation strengthening to meet the needs of engineering applications. | X.S.Liu R.Li X.F.Fan Q.Q.Liu X.Tong A.X.Li S.Xu H.Yang S.B.Yu M.H.Jiang C.Huo P.F.Yu M.T.Dove G.Li | 2023 | Journal of Materials Science & Technology2023，，3： | 1 |

| 12 | Investigating the use of an ionic liquid for rare earth mineral flotation显示文摘Common collectors for rare earth mineral(REM) flotation,which include carboxylates and hydroxamates,face problems such as being non-selective and sensitive to impurity ions.A type of ionic liquid(IL),tetraethylammonium mono-(2-ethylhexyl)2-ethylhexyl phosphonate([N_(2222)][EHEHP]),has been investigated previously for rare earth elements(REE) solvent extraction,and was proven to be selective and effective.In this work,[N_(2222)][EHEHP] was evaluated as a collector in bastnasite(a primary REM source for REE production) flotation for the first time.The results were compared with quartz and hematite,two common gangue minerals in REM deposits.Zeta potential measurements and Fouriertransform infrared spectroscopy(FT-IR) were completed to investigate the surface chemical properties involved in the flotation of these minerals using this collector.The findings were compared with microflotation results.FT-IR and zeta potential measurements suggest adsorption of the collector’s phosphonate group onto bastnäsite and hematite,likely through chemisorption;whereas for quartz,the minimum micro flotation recovery is likely due to no adsorption of IL on its surface.Micro flotation re sults show higher collectability of [N_(2222)] [EHEHP] for hematite than bastnasite,the latter only shows appreciable recovery at pH 5 with elevated dosage of IL(500 g/t).To achieve better separation,a two-stage flotation scheme was designed and evaluated by bench scale flotation on a synthetic mineral mixture.The concentrates and tails were analyzed by magnetic separation,and it is found that bastnasite recovery over 90% with maximum upgrade ratio 1.7 can be achieved with elevated collector dosage. | R.Li C.Marion E.R.L.Espirtu R.Multani Xiaoqi Sun K.E.Waters | 2021 | Journal of Rare Earths2021，39，7： | 0 |
