3Laser performance upgrade for precise ICF experiment in SG-Ⅲ laser facility显示文摘The SG-Ⅲlaser facility(SG-Ⅲ)is the largest laser driver for inertial confinement fusion(ICF)researches in China,which has 48 beamlines and can deliver 180 kJ ultraviolet laser energy in 3 ns.In order to meet the requirements of precise physics experiments,some new functionalities need to be added to SG-Ⅲand some intrinsic laser performances need upgrade.So at the end of SG-Ⅲ's engineering construction,the 2-year laser performance upgrade project started.This paper will introduce the newly added functionalities and the latest laser performance of SG-Ⅲ.With these function extensions and performance upgrade,SG-Ⅲis now fully prepared for precise ICF experiments and solidly paves the way towards fusion ignition.Wanguo Zheng Xiaofeng Wei Qihua Zhu Feng Jing Dongxia Hu Xiaodong Yuan Wanjun Dai Wei Zhou Fang Wang Dangpeng Xu Xudong Xie Bin Feng Zhitao Peng Liangfu Guo Yuanbin Chen Xiongjun Zhang Lanqin Liu Donghui Lin Zhao Dang Yong Xiang Rui Zhang Fang Wang Huaiting Jia Xuewei Deng 2017Matter and Radiation at Extremes2017,2,5:13
4Atomic structures of Zr-based metallic glasses显示文摘The atomic structures of Zr-Ni and Zr-Ti-Al-Cu-Ni metallic glasses were investigated by using classical molecular dynamic (MD),reverse Monte Carlo (RMC),ab initio MD (AIMD) simulations and high resolution transmission electron microscopy (HRTEM) techniques. We focused on the short-range order (SRO) and medium-range order (MRO) in the glassy structure. It is shown that there are icosahedral,FCC-and BCC-type SROs in the Zr-based metallic glasses. A structural model,characterized by imperfect ordered packing (IOP),was proposed based on the MD simulation and confirmed by the HRTEM observation. Furthermore,the evolution from IOP to nanocrystal during the crystallization of metallic glasses was also ex-plored. It is found that the growth from IOP to nanocrystal proceeds through three distinct stages: the formation of quasi-ordered structure with one-dimensional (1D) periodicity,then 2D periodicity,and finally the formation of 3D nanocrystals. It is also noted that these three growth steps are crosslinked.HUI XiDong LIU XiongJun GAO Rui HOU HuaiYu FANG HuaZhi LIU ZiKui CHEN GuoLiang 2008Science China(Physics,Mechanics & Astronomy)2008,51,4:8
5Magnetocaloric effect in Er-Al-Co bulk metallic glasses显示文摘A series of Er-Al-Co bulk metallic glasses (BMGs) have been prepared by the copper mold casting method. The glass forming ability and magnetocaloric effect (MCE) for these alloys have been investigated. The second-order magnetic transition from para-magnetic to ferromagnetic states takes place at about 9 K. These BMGs exhibit excellent MCE because of their large effective magneton number; Er56Al24Co20 BMG has a maximum entropy change and refrigeration capacity of 16.06 J kg-1 K-1 and 546 J kg-1,respectively,under the field of 50 kOe (10 kOe=795.775 kA/m) indicating that these BMGs are potential candidate magnetic materials for hydrogen liquefaction.HUI XiDong XU ZhiYi WU Yuan CHEN XiaoHua LIU XiongJun LU ZhaoPing 2011Chinese Science Bulletin2011,56,36:6
6Vacancy formation enthalpies of high-entropy FeCoCrNi alloy via first-principles calculations and possible implications to its superior radiation tolerance显示文摘Because atoms in high-entropy alloys(HEAs) coordinate in very different and distorted local environments in the lattice sites, even for the same type of constituent, their point defects could highly vary.Therefore, theoretical determination of the thermodynamic quantities(i.e., defect formation enthalpies)of various point defects is rather challenging because each corresponding thermodynamic quantity of all involve constituents is not unique. The knowledge of these thermodynamic quantities is prerequisite for designing novel HEAs and understanding the mechanical and physical behaviors of HEAs. However,to date there has not been a good method to theoretically derive the defect formation enthalpies of HEAs. Here, using first-principles calculations within the density functional theory(DFT) in combination of special quasi-random structure models(SQSs), we have developed a general method to derive corresponding formation enthalpies of point defects in HEAs, using vacancy formation enthalpies of a four-component equiatomic fcc-type FeCoCrNi HEA as prototypical and benchmark examples. In difference from traditional ordered alloys, the vacancy formation enthalpies of FeCoCrNi HEA vary in a highly wide range from 0.72 to 2.89 eV for Fe, 0.88–2.90 eV for Co, 0.78–3.09 eV for Cr, and 0.91–2.95 eV for Ni due to high-level site-to-site lattice distortions and compositional complexities. On average, the vacancy formation enthalpies of 1.58 eV for Fe, 1.61 eV for Cr, 1.70 eV for Co and 1.89 eV for Ni are all larger than that(1.41 eV) of pure fcc nickel. This fact implies that the vacancies are much more difficult to be created than in nickel, indicating a reasonable agreement with the recent experimental observation that FeCoCrNi exhibits two orders of amplitudes enhancement of radiation tolerance with the suppression of void formation at elevated temperatures than in pure nickel.Weiliang Chen Xueyong Ding Yuchao Feng Xiongjun Liu Kui Liu Z.P.

8Alloying effects of the elements with a positive heat of mixing on the glass forming ability of Al-La-Ni amorphous alloys显示文摘The effects of Sn and Ga additions on the glass forming ability(GFA)of(Al86La5Ni9)100 xSnx(x=0,0.2,0.3,0.5,0.7,1 and 2at.%)and(Al86La5Ni9)100 xGax(x=0,0.2,0.5,1 and 1.5 at.%)alloys were systematically investigated.Unlike common microalloying methods,both Sn and Ga have a positive heat of mixing with the main component of Al.Our analysis confirmed that proper Sn addition can suppress the strong formation ofα-Al and enhance the GFA due to the positive heat of mixing between Sn and Al and the large difference in their atomic sizes.While the addition of Ga to the base alloy acted as the nucleation cites forα-Al and accelerated precipitation of theα-Al phase,thus deteriorating the GFA.CHEN ZiPan GAO JingEn WU Yuan WANG Hui LIU XiongJun LU ZhaoPing 2014Science China(Physics,Mechanics & Astronomy)2014,57,1:3

10Interpretable machine-learning strategy for soft-magnetic property and thermal stability in Fe-based metallic glasses显示文摘Fe-based metallic glasses(MGs)have been extensively investigated due to their unique properties,especially the outstanding soft-magnetic properties.However,conventional design of soft-magnetic Fe-based MGs is heavily relied on“trial and error”experiments,and thus difficult to balance the saturation flux density(Bs)and thermal stability due to the strong interplay between the glass formation and magnetic interaction.Herein,we report an eXtreme Gradient Boosting(XGBoost)machine-learning(ML)model for developing advanced Fe-based MGs with a decent combination of Bs and thermal stability.Zhichao Lu Xin Chen Xiongjun Liu Deye Lin Yuan Wu Yibo Zhang Hui Wang Suihe Jiang Hongxiang Li Xianzhen Wang Zhaoping Lu 2020npj Computational Materials2020,,1:2
11Evaluation of the relative γ-ray intensities emitted from ^(56)Co and ^(66)Ga显示文摘56Co and 66Ga with γ-ray energies covering the range of 0.84-3.55 and 0.68-4.81MeV, respectively, are important radionuclides for Ge detector calibration. The newly evaluated relative γ-ray intensities were recommended using the measurements finished after 2000 year by Baglin and Browne in 2004. In 2005 China groups measured the relative γ-ray intensities. The China measurements were about 2% systematically lower than other measurements and these evaluations. In this paper the discrepancies among these measurements and the evaluations are analyzed carefully and the new evaluations are re-recommended.YU Weixiang HUANG Xiaolong CHEN Xiongjun LU Hanlin 2009Nuclear Science and Techniques2009,20,6:1
12In-situ Mg_(77)Cu_(12)Zn_5Y_6 bulk metallic glass matrix composite with extraordinary plasticity显示文摘We report experimental evidence of in-situ Mg77Cu12Zn5Y6 bulk metallic glass (BMG) ma- trix composite with extraordinary plastic strain of 18.5% and specific strength of 4.31×105 N·m·kg?1, which are the highest plasticity and specific strength in Mg base BMG alloys reported to date. The excel- lent mechanical properties are attributed to the for- mation of the composite structure which is composed of amorphous matrix and hexagonal-close-packed (hcp) Mg solid solution needle phase with a width less than 500 nm. As plastic phase, the Mg needles not only possess the capability of deformation but also have work hardening phenomenon effect. They give rise to multiple shear bands, and hinder the propagation of local shear band in amorphous matrix.HUI Xidong DONG Wei WANG Meiling LIU Xiongjun YU Jialing CHEN Guoliang 2006Chinese Science Bulletin2006,51,2:1

142-10 Direct Measurement of the Main s-process Neutron Source显示文摘The 13C(, n)16O reaction is the key neutron source reaction for the main s-process nucleosynthesis[1]. Theimportant energy range (Gamow window) for the 13C( , n)16O reaction during the s-process spans from 140 to230 keV in the center of mass frame. Because of the Coulomb barrier, the cross sections drop exponentially asmeasurement approaches the Gamow window energies. Limited by cosmic ray background and the available beamintensity, the ground-based measurements are limited to energies above 280 keV. Therefore, the extrapolationbased on R-matrix calculation and/or in-direct measurement is the current method to estimate the cross sectionsfor astrophysical interest with limited precision. Moreover, due to the existence of sub-threshold resonances, thereare rather large uncertainties associated with the extrapolated cross sections which limit the precision of the currentreaction rate and thus prevent us from a complete understanding of the nucleosynthesis of heavy elements.Tang Xiaodong Ren Jie Chen Han Chen Zhijun Chen Xiongjun Huang Hanxiong Jiang Liyang Li Kuoang Ruan Xuchao Wang Shuo Zhang Ningtao the JUNA collaboration 2014IMP & HIRFL Annual Report2014,,1:0
15Effects of trace elements on mechanical properties of the TiZrHfNb high-entropy alloy显示文摘Refractory high-entropy alloys have great potential to be utilized as high-temperature materials,and the repeatability and reproducibility of their mechanical properties are critical for practical applications.In this work,nevertheless,we found that the mechanical properties of the TiZrHfNb HEA greatly varied with the content of impurities in the samples even using high-purity raw materials.Specifically,the oxygen impurity is mainly responsible for the increment of the yield stress due to the strong interstitial hardening effect,whilst the ductility deterioration closely associates with the content of metalloid elements B,C,and Si.Our analysis reveals that the metalloid elements not only tend to segregate at grain boundaries but also enhance the aggregation of Zr and Ti.Such co-segregation induced the formation of strong(Zr,Ti)-metalloid bonds,resulting in grain boundary embrittlement and brittle fracture.Our current work demonstrates that the impurity contents in refractory HEAs need to be strictly controlled during production in order to improve their stability of mechanical performance.Xiaoyuan Yuan Yuan Wu Meisa Zhou Xiongjun Liu Hui Wang Suihe Jiang Xiaobin Zhang Honghui Wu Xiaochun Liu Zipan Chen Xiangqi Xu Zhaoping Lu 2023Journal of Materials Science & Technology2023,,21:0
16Research progress and application of deep in-situ condition preserved coring and testing显示文摘With the depletion of shallow resources,the exploration of deep earth resources has become a global strategy.The study of the different patterns in the physical mechanical properties of rocks at different occurrence depths is the basis for exploring deep into the earth,with the core and premise being the acquisition and testing of deep in-situ core specimens.Based on the original idea of deep in-situ condition preserved coring(ICP-Coring)and testing,combined with theoretical modeling,numerical analysis,test platform development,indoor testing and engineering application,the principles and technologies of deep ICP-Coring are developed.This principle and technology consists of five parts:in-situ pressurepreserved coring(IPP-Coring),in-situ substance-preserved coring(ISP-Coring),in-situ temperaturepreserved coring(ITP-Coring),in-situ light-preserved coring(ILP-Coring),and in-situ moisturepreserved coring(IMP-Coring).The theory and technology of temperature and pressure reconstruction at different occurrence depths and in different environments are proposed,and prototype trial production was completed by following the principle of displacement and tests based on the in-situ reconstructed environment.The notable advances are as follows:(1)Deep in-situ coring system:A pressure-preserved controller with an ultimate bearing capacity greater than 140 MPa,highperformance(temperature-resistant,pressure-resistant,and low thermally conductive)temperaturepreserved materials,an active temperature control system,and high-barrier quality-preserved membrane materials were developed;a deep ICP-Coring capacity calibration platform was independently developed,a deep in-situ coring technology system was developed,and the acquisition of deep in-situ cores was realized.(2)In-situ storage displacement system:Following the dual-circuit hydraulic design idea,a single-drive source push-pull composite grabbing mechanism was designed;the design of the overall structure for the deep in-situ displacement storage system and ultrahigh pressure cabin structure was completed,which could realize docking the coring device and core displacement in the in-situ reconstructed environment.(3)Test analysis system:A noncontact acoustic-electric-magnetic test system was developed under the in-situ reconstructed environment,and the errors between the test results and traditional contact test results were mostly less than 10%;a detachable deep in-situ core true triaxial test system was developed,which could perform loading tests for deep in-situ cores.The relevant technological achievements were successfully applied to the exploration and development of deep resources,such as deep mines,deep-sea natural gas hydrates,and deep oil and gas.The research results provide technical and equipment support for the construction of a theoretical system for deep in-situ rock mechanics,the development of deep earth resources and energy,and the scientific exploration of different layers and occurrence depths(deep and ultradeep)of the Earth.Heping Xie Yunqi Hu Mingzhong Gao Ling Chen Ru Zhang Tao Liu Feng Gao Hongwei Zhou Xiaobo Peng Xiongjun Li Jianbo Zhu Cunbao Li Ruidong Peng Yanan Gao Cong Li Jianan Li Zhiqiang He 2023International Journal of Mining Science and Technology2023,33,11:0
