| 1 | Ba_(1-x)K_(x)Fe_(2)As_(2)铁基超导带材的织构调控与性能研究显示文摘高性能超导材料是高场磁体开发的基础.铁基超导体具有很高的上临界场和较低的各向异性,在高场应用领域具有广阔的前景,如加速器磁体、高场核磁共振谱仪、医用磁共振成像系统和可控核聚变装置.本文通过一种易于规模扩展的工艺路线制备了铜银复合包套Ba_(1-x)K_(x)Fe_(2)As_(2)(Ba122)超导带材,其传输临界电流密度在4.2 K和10 T外磁场下为1.1×10^(5)A cm^(-2),达到了105A cm^(-2)的实用化水平.该制备路线结合了平辊轧制织构化工艺和热等静压致密化工艺.通过改变轧制工艺参数,可以调控多晶的织构度.研究表明,在轧制过程中施加较大的变形量可以提高Ba122超导带材的c轴织构度,从而提高其传输性能.对高性能带材的微观结构表征表明,其Ba122相元素分布均匀,晶粒细小且连接性良好,有助于提高晶界钉扎作用.磁光成像研究表明,即使在25 K,样品中仍然存在较大的磁化电流.本文采用的易于规模化扩展且低成本的制备路线在Ba122超导带材中获得了很高的传输性能,表明铁基超导材料在未来高场应用中是潜在的有力竞争者. | 刘世法 姚超 黄河 董持衡 郭文文 成者 朱炎昌 Satoshi Awaji 马衍伟 | 2021 | Science China Materials2021，64，10： | 2 |

| 9 | Properties of seven-filament Cu/Ag-sheathed(Ba,K)Fe_(2)As_(2)tapes fabricated from round and square wires显示文摘Iron-based superconductor,a promising candidate for high-field applications,has attracted significant attentions.For practical utilization,the superconducting tapes should have high transport critical current density(J_(c)),low production cost,larger mechanical strength and good homogeneity.In this study,seven-filament Cu/Agsheathed(Ba,K)Fe_(2)As_(2)tapes were fabricated from round and square wires.It is found that the tapes rolled from square wires have a desirable uniformity of filament deformation and distribution,compared with the ones rolled from round wires.Moreover,the J_c of tape was obviously improved by using square drawing dies instead of traditional round ones.For the tapes rolled from square wires annealed under ambient and 2 MPa by hot pressing,the transport J_c values reached 1.51×10^(4) A·cm^(-2)and 4.86×10^(4) A.cm^(-2)(4.2K,10T),respectively.The deformation process on the cross section of the tapes during rolling was analyzed by using the powder-flow model.These results indicate a potential application of Cu/Ag(Ba,K)Fe_(2)As_(2)tapes in high-magnetic-field region. | Zhen-Kun Jin Cong Liu Chao Yao Liu Li He Huang Dong-Liang Wang Chi-Heng Dong Kai Wang Xian-Ping Zhang Satoshi Awaji Yan-Wei Ma | 2021 | Rare Metals2021，40，12： | 0 |
| 10 | A VASUALIZATION FOR THE DYNAMIC BEHAVIORS OF THE MIXTURE OF WATER MASS FOR NORTHWESTERN PACIFIC NEAR JAPAN显示文摘Recent studies are focusing on the distribution of water mass because the mixture region of water mass is highly related to the rich fishing grounds[Yasuda I.,Watanabe Y.,Fish.Oceanogr.3(3):172–181,1994].Due to the large data size and time-varying property,efficient exploration and visualization of the ocean data is always extremely challenging.To extract the dynamic behaviors of the water mass and its mixture from a large-scale simulated ocean dataset,we developed an efficient visualization system by applying our volume compression method and our volume rendering method.This system allows us to investigate the time-varying distributions of ocean physical properties,additionally from the user’s perspective and requirements.In the experiments,we show the generality and expressiveness by applying our system for single-and multi-property visualizations to find some significant ocean water mass.Consequently,we could obtain a clear visualization result to show the dynamic behaviors of the mixture of water mass for simulation data regarding a location in the northwestern Pacific near Japan. | KUN ZHAO SATOSHI NAKADA NAOHISA SAKAMOTO KOJI KOYAMADA CHANDRAJIT BAJAJ YOICHI ISHIKAWA TOSHIYUKI AWAJI TEIJI IN SEI-ICHI SAITOH | 2013 | International Journal of Modeling, Simulation, and Scientific Computing2013，4，S01： | 0 |
