| 1 | Influence of Substrate Negative Bias on Structure and Properties of TiN Coatings Prepared by Hybrid HIPIMS Method显示文摘TiN coatings were deposited using a hybrid home-made high power impulse magnetron sputtering(HIPIMS)technique at room temperature.The effects of substrate negative bias voltage on the deposition rate,composition,crystal structure,surface morphology,microstructure and mechanical properties were investigated.The results revealed that with the increase in bias voltage from-50 to-400 V,TiN coatings exhibited a trend of densification and the crystal structure gradually evolved from(111) orientation to(200)orientation.The growth rate decreased from about 12.2 nm to 7.8 nm per minute with the coating densification.When the bias voltage was-300 V,the minimum surface roughness value of 10.1 nm was obtained,and the hardness and Young's modulus of TiN coatings reached the maximum value of 17.4 GPa and 263.8 GPa,respectively.Meanwhile,the highest adhesion of 59 N was obtained between coating and substrate. | Zhenyu Wang Dong Zhang Peiling Ke Xincai Liu Aiying Wang | 2015 | Journal of Materials Science & Technology2015，31，1： | 10 |
| 2 | Ultrathin, flexible, and high-strength Ni/Cu/metallic glass/Cu/Ni composite with alternate magneto-electric structures for electromagnetic shielding显示文摘Electromagnetic interference(EMI)shielding materials with ultrathin,flexible,superior mechanical and thermal management properties are highly desirable for smart and wearable electronics.Here,ultrathin and flexible Ni/Cu/metallic glass/Cu/Ni(Ni/Cu/MG)multilayer composite with alternate magnetic and electrical structures was designed via facial electroless plating of Cu and Ni on an Fe-based metallic glass.The resultant 0.02 mm-thick Ni/Cu/MG composite displays a superior EMI shielding effectiveness(EMI SE)of 35 dB and a great EMI SE/t of 1750 dB/mm,which is greater than those of composites with monotonous multilayer or homogeneous structures.The improved EMI SE originates from the massive ohmic losses,the enhanced internal reflection/absorption,and the abundant interfacial polarization loss.Particularly,Ni/Cu/MG exhibits a high tensile strength of up to 1.2 GPa and outstanding mechanical stability,enabling the EMI SE remains unchanged after 10,000 times of bending.Moreover,Ni/Cu/MG has excellent Joule heating characteristics and thermal stability,which is very suitable for heating components of wearable hyperthermia devices. | Zenan Ma Jiawei Li Jijun Zhang Aina He Yaqiang Dong Guoguo Tan Mingqiang Ning Qikui Man Xincai Liu | 2021 | Journal of Materials Science & Technology2021，，22： | 3 |
| 3 | Structure and magnetostriction of Tb_(0.4)Nd_(0.6)(Fe_(0.8)Co_(0.2))_(1.90) alloy prepared by solid-state synthesis显示文摘Mechanical alloying (MA) and subsequent solid sintering process was used to prepare the Nd-containing magnetostrictive Tb0.4Nd0.6(Fe0.8Co0.2)1.90 alloy. The structure, thermal stability and phase transformation were investigated as functions of composition, milling process and annealing temperature. An amorphous phase was formed by high-energy ball milling for 5 h with the ball-to-powder weight ratio of 20:1, which crystallized into MgCu2-type and PuNi3-type crystalline structure with different annealing temperatures. The magnetoelastic properties were investigated by means of a standard strain technique. The high Nd-content (Tb,Nd)(Fe,Co)2 Laves phase for the composition Tb0.4Nd0.6(Fe0.8Co0.2)1.90 was synthesized by MA process plus annealing at 500 ℃ for 30 min. | Liu Jinjun Wang Rong Yin Hongyun Liu Xincai Si Pingzhan Du Juan | 2012 | Rare Metals2012，31，6： | 2 |
| 4 | Structure and magnetic properties of mechanically alloyed Tb_(0.2)Pr_(0.8)(Fe_(0.4)Co_(0.6))_(1.93) and magnetostriction of its epoxy composite显示文摘The C15 Laves phase with composition Tb0.2Pr0.8(Fe0.4Co0.6)1.93 was synthesized by mechanical alloying (MA) and subsequent annealing process. The structure and magnetic properties of Tb0.2Pr0.8(Fe0.4Co0.6)1.93 were investigated by means of X-ray diffraction (XRD), a vibrating sample magnetometer, and a standard strain technique. The effect of annealing on the structure and magnetic properties was studied. The analysis of XRD shows that the high Pr-content Tb0.2Pr0.8(Fe0.4Co0.6)1.93 alloy with the single phase of MgCu2-type structure can be success-fully synthesized by MA method. The sample annealed at 450°C is found to have a coercivity of 196 kA/m at room temperature. An ep-oxy/Tb0.2Pr0.8(Fe0.4Co0.6)1.93 composite was produced by a cold isostatic pressing technique. A large magnetostriction of 400 ppm, at an ap-plied magnetic field of 800 kA/m, was found for the composite. The epoxy-bonded Tb0.2Pr0.8(Fe0.4Co0.6)1.93 composite combines a high mag-netostriction with a significant coercivity, which is a promising magnetostrictive material. | LIU Jinjun LIU Xincai PAN Jing JIANG Chengyong | 2009 | Rare Metals2009，28，1： | 2 |

| 6 | Crystallization behaviour and high coercivity of (Nd,Pr)_(13)Fe_(80)Nb_1B_6 melt-spun ribbons显示文摘Amorphous (Nd,Pr)13Fe80Nb1B6 ribbons were crystallized at 670-730°C for 5-25 min to study the effects of isothermal crystallization on their behavior and magnetic properties. XRD results indicate that the isothermal incubation time is 12, 5, and less than 5 min at 670, 700, and 730°C, respectively. High coercivities, with the maximum value of iHc = 1616 kA/m at 700°C for 19 min, measured by a physical property measurement system, are obtained in the crystallized ribbons. This is mainly attributed to the addition of Pr and Nb, because Pr2Fe14B has a higher anisotropic field than Nd2Fe14B, and Nb enriched in the grain boundary regions can not only reduce the exchange-coupling effects among hard grains, but also impede grain growth during the crystallization process. In addition, it should also be related to the characteristics of the furnace that the authors designed. | GUO Pengju LIU Xincai PAN Jing XU Feng LI Yong CUI Ping | 2009 | Rare Metals2009，28，3： | 1 |

| 8 | Magnetic texture of Nd_2Fe_(14)B solidified in the surface layer of anisotropic sintered-magnets显示文摘The arrangements of the easy magnetization axis [001] of columnar Nd2Fe14B crystals in the laser scanned layer on anisotropic sintered Nd15Fe77B8 magnets were investigated by XRD and the Bitter method. The results show that the common effects of both the heat flux and the substrate magnetization orientation constrain the columnar Nd2Fe14B solidified from the laser melting pool to form the c-axis texture orientated with the same direction as that of the substrate, when the geometric relationship between the heat flux in the laser scanning layer and c-axis texture orientation of the substrate is perpendicular to each other, and if the laser scanning velocity is no less than 25 mm·min-1. The c-axes of columnar Nd2Fe14B crystals are no longer randomly distributed in the plane normal to their preferential growing direction as they are randomly done in both ingots cooled by water-cooling copper mould and directionally solidified Nd-Fe-B rods. | PAN Jing LIU Xincai TU Fenghua | 2006 | Rare Metals2006，25，z1： | 1 |

| 11 | Multi-functional layered double hydroxides supported by nanoporous gold toward overall hydrazine splitting显示文摘Layered double hydroxides have demonstrated great potential for the oxygen evolution reaction,which is a crucial half-reaction of overall water splitting.However,it remains challenging to apply layered double hydroxides in other electrochemical reactions with high efficiency and stability.Herein,we report two-dimensional multifunctional layered double hydroxides derived from metalorganic framework sheet precursors supported by nanoporous gold with high porosity,which exhibit appealing performances toward oxygen/hydrogen evolution reactions,hydrazine oxidation reaction,and overall hydrazine splitting.The as-prepared catalyst only requires an overpotential of 233 mV to reach 10 mA·cm^(-2) toward oxygen evolution reaction.The overall hydrazine splitting cell only needs a cell voltage of 0.984 V to deliver 10 mA·cm^(-2),which is far more superior than that of the overall water splitting system(1.849 V).The appealing performances of the catalyst can be contributed to the synergistic effect between the metal components of the layered double hydroxides and the supporting effect of the nanoporous gold substrate,which could endow the sample with high surface area and excellent conductivity,resulting in superior activity and stability. | Yongji Qin Huijie Cao Qian Liu Shaoqing Yang Xincai Feng Hao Wang Meiling Lian Dongxing Zhang Hua Wang Jun Luo Xijun Liu | 2024 | Frontiers of Chemical Science and Engineering2024，18，1： | 0 |

| 14 | 电子束探针模拟和初步测试显示文摘Electron beam probe(EBP)is a non-interceptive device for beam profile measurement,which is under heavy development at many accelerator laboratories worldwide,i.e.SNS,FNAL,BINP,etc.,since the principle using charged particles as a probe beam to determine charge distribution is raised since the 1970s[1].EBP is especially suitable for high power accelerators because of its non-interceptability,and mainly devoted to circular machine.An EBP uses the deflection of a low energy electron beam in the target beam electromagnetic field to infer the profile information of the target beam.Measuring the deflection angle as a function of different impacts,one can reconstruct the beam distribution in the x or y direction. | Feng Yongchun Mao Ruishi Yin Yan Chen Yucong Dong Xiaoxia Li Juan Ding Jiajian You Yaoyao Liu Tong Kang Xincai Wang Yanmou Ma Weinian Song Haihong Li Weilong Xu Zhiguo Zhao Tiecheng | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
| 15 | FePCCu nanocrystalline alloys with excellent soft magnetic properties显示文摘The effect of Cu addition on crystallization behavior and soft magnetic properties of Fe 84xP10C6 Cux (x= 0 1.15) alloys was investigated. Low-cost FePCCu nanocrystalline alloys dispersed with α-Fe phase with an average grain size of 15-35nm were obtained by appropriately annealing the melt-spun ribbons at 683K for 5min. The Fe 83.25P10C6Cu0.75 nanocrystalline alloy exhibits a high B s of 1.65T, low H c of 3.3A/m and high eat 1kHz of21 100, which is superior to the traditional FePC soft magnetic alloys. The core loss is as low as 0.32W/kg at1.0 T and 50Hz, which is 60% that of nonoriented Fe 6.5 mass% Si-steel. It is encouraging to synthesize this Fe-based nanocrystalline alloy with excellent soft-magnetic properties even using commercially industry-grade raw materials, which is promising for the future industrial applications. | JIN YunLong FAN XingDu MEN He LIU XinCai SHEN BaoLong | 2012 | Science China(Technological Sciences)2012，55，12： | 0 |
| 16 | Genesis and distribution of oils in Mahu Sag,Junggar Basin,NW China显示文摘Based on the geological and geochemical analysis of potential source rocks in different formations and the classification of crude oil types,combined with the hydrocarbon generation thermal simulation experiments,the source,genesis,and distribution of different types of oils in the Mahu large oil province of the Junggar Basin are investigated.Four sets of potential source rocks are developed in the Mahu Sag.Specifically,the source rocks of the Permian Fengcheng Formation have the highest hydrocarbon generation potential and contain mainly TypesⅡandⅠorganic matters,with a high oil generation capacity.In contrast,the source rocks in other formations exhibit lower hydrocarbon generation potential and contain mainly TypeⅢorganic matter,with dominant gas generation.Oils in the Mahu Sag can be classified as three types:A,B and C,which display ascending,mountainous and descending C_(20)-C_(21)-C_(23)tricyclic terpenes abundance patterns in sequence,and gradually increasing relative content of tricyclic terpenes and sterane isomerization parameters,indicating an increasing oil maturity.Different types of oils are distributed spatially in an obviously orderly manner:Type A oil is close to the edge of the sag,Type C oil is concentrated in the center of the sag,and Type B oil lies in the slope area between Type A and Type C.The results of oil-source correlation and thermal simulation experiments show that the three types of oils come from the source rocks of the Fengcheng Formation at different thermal evolution stages.This new understanding of the differential genesis of oils in the Mahu Sag reasonably explains the source,distribution,and genetic mechanism of the three types of oils.The study results are of important guidance for the comprehensive and three-dimensional oil exploration,the identification of oil distribution in the total petroleum system,and the prediction of favorable exploration areas in the Mahu Sag. | DANG Wenlong GAO Gang YOU Xincai WU Jun LIU Shiju YAN Qi HE Wenjun GUO Liulinbo | 2023 | Petroleum Exploration and Development2023，50，4： | 0 |
| 17 | Recent progress of grain boundary diffusion process for hot-deformed Nd-Fe-B magnets显示文摘Grain boundary diffusion process(GBDP)was first proposed for sintered Nd-Fe-B magnets to achieve the high utilization efficiency of heavy rare earth elements.Recent success of fabricating high performance nanocomposite magnets by GBDP indicates that this method also exerts huge applicable potential on hot-deformed Nd-Fe-B magnets.In this review,the development and magnetic property enhancement mechanisms of different diffusion methods proposed on hot-deformed magnets were thoroughly elucidated.Moreover,the improve room for further property enhancement and the accompanying problems of GBDP on hot-deformed magnets are also discussed in this article. | Min Zhao Na Liu Xu Tang Renjie Chen Jinyun Ju Wenzong Yin Yeyuan Du Aru Yan Xincai Liu Jing Pan Zhiyi Xu | 2023 | Journal of Rare Earths2023，41，4： | 0 |
